ABSTRACT
Energy efficiency is the least expensive way for power and process industries to
meet a growing demand for cleaner energy, and this applies to the power
generating industry as well.
Auxiliary equipment has a critical role in the safe operation of the plant and can
be found in all plant systems. Perhaps the diversity of applications is one reason
why a comprehensive approachto auxiliaries is needed to reduce their proportion
of gross power.
In-plant electrical power, when taken from the generator bus, may be priced
artificially low in some utility companies’ auxiliary lifecycle calculations. A
process industrycustomer, however, must always pay high commercial rates (and
sometimes penalties), thus providing a strong incentive to improve their auxiliary
energy efficiency. Price dis-incentives, regulations permitting cost-pass thru.
Based on analysis of the energy flow of hydroelectric generating units (HGU) at
different loading, the energy indices of the unit are calculated using related
formulas.
This project report takes a comprehensive view on reduction in auxiliary
consumption and describes some common approaches to energy efficient design
which can be applied in retrofit and new plant projects.

INTRODUCTION
Growing economy, expanding energy intensive industries, rising urbanization,
increasing population and on top of all, a quest for modernization and improved
quality of life have increased the demand of electricity in India.
Energy generation is one of the major key factors for economic and social
development in all the developed and developing nations of the world.
Hydropower is the most widely used renewable energy source worldwide,
contributing almost with 18.5% to the fulfilment of the planet electricity
generation. Hydroelectric generation is a continuous productionprocess inwhich
hydraulic energy is converted into mechanical energy and finally converted into
electric energy. This is a clean, renewable and economic way of energy
production. Every single kWh of hydropower makes sense because this means a
small reduction of fossil or nuclear fuel burning. The hydraulic energy is a
valuable natural resource, and increasing the efficiency of hydropower
production is a long term goal in the field of hydropower engineering because it
greatly contributes to the economy and environment. Usually, the rated efficiency
of a large generator is above 98%, the efficiency of the water turbine is the key
element in the overall efficiency of a hydroelectric generating unit (HGU). A
significant performance factorin the power generation from a hydroelectric plant
is the efficiency of the units. Each generating unit experiences three types of
losses. These losses occur in the turbine, the generator, and the penstock. In the
turbine and the generator losses happen due to mechanical friction and heat
dissipation in the process to convert kinetic energy into mechanical energy and
mechanical energy into electrical energy, respectively.

1.3) Hydro Power
By taking advantage of gravity and the water cycle, we have tapped into one of
nature's engines to create a useful form of energy. In fact, humans have been
capturing the energy of moving water for thousands of years. Today, harnessing
the power ofmoving water to generate electricity, known as hydroelectric power,
is the largest source of emissions-free, renewable electricity in India and
worldwide.
Although the generation of hydropowerdoes not emit air pollution or greenhouse
gas emissions, it can have negative environmental and social consequences.
Blocking rivers with dams can degrade water quality, damage aquatic and
riparian habitat, block migratory fish passage, and displace local communities.
The benefits and drawbacks of any proposed hydropower development must be
weighed before moving forward with any project. Still, if it's done right,
hydropower can be a sustainable and non-polluting source of electricity that can
help decrease our dependence on fossil fuels and reduce the threat of global
warming.
India is endowed with economically exploitable and viable hydro potential
assessed to be about 84,000 MW at 60% load factor. In addition, 6740 MW in
terms of installed capacity from Small, Mini, and Micro Hydel schemes have
been assessed. Also, 56 sites for pumped storage schemes with an aggregate
installed capacity of 94,000 MW have been identified. It is the most widely used
form of renewable energy. India is blessed with immense amount of hydro-
electric potential and ranks 5th in terms of exploitable hydro-potential on global
scenario.
The presentinstalled capacity as of31 May 2014 is approximately 40,661.41 MW
which is 16.36% of total electricity generation in India. The public sector has a
11. 11
predominant share of 97% in this sector. National Hydroelectric Power
Corporation (NHPC), Northeast Electric Power Company (NEEPCO), Satluj jal
vidyut nigam (SJVNL), Tehri Hydro Development Corporation, NTPC-Hydro
are a few public sector companies engaged in development of hydroelectric
power in India.
1.4) Solar Power
India is endowed with vast solar energy. Thesolar radiation of about 5,000 trillion
kWh per year is incident over its land mass with average daily solar
power potential of 0.25 kWh per m2 of used land area with the available
commercially proven technologies. As of 31 March 2016, the installed capacity
was 6,763 MW. India expects to install an additional 10,000 MW by 2017, and a
total of 100,000 MW by 2022.
Installation of solar power plants require nearly 2.4 hectares (6 acres) land per
MW capacity which is similar to coal-fired power plants when life cycle coal
mining, consumptive water storage & ash disposal areas are also accounted and
hydro power plants when submergence area of water reservoir is also accounted.
1.33 million MW capacity solar plants can be installed in India on its 1% land
(32,000 square km)
Land acquisition is a challenge to solar farm projects in India. Some state
governments are exploring means to address land availability through
innovation; for example, by exploring means to deploy solar capacity above
their extensive irrigation canal projects, thereby harvesting solar energy while
reducing the loss of irrigation water by solar evaporation. The state of Gujarat
was first to implement the Canal Solar Power Project, to use 19,000 km
(12,000 mi) long network of Narmada canals across the state for setting up solar
panels to generate electricity. It was the first ever such project in India.

BHIRA GENERATING STATION
2.1) GeographicalLocation
Bhira Hydel Power Generating Station is situated in Raigad District about 160
kms from Mumbai. A branch road of 28 Kms from Varasgaon on Mumbai-Goa
highway leads to the Power Station.
2.2) Introduction
Bhira Power House was commissioned in the year 1927. This is the largest
Hydro-Electric Generating Station of The Tata Power Company Limited.
Originally, there were 5 Units of 18 MW each, supplied by M/s English Electric
of UK. The sixth Unit (presently numbered as Unit No. 1) of 22 MW capacity
was added during the year 1951-52. This was supplied by M/s Westinghouse of
USA with Morgan Smith Turbines. Later on, the capacity of the other 5 units was
raised to 22 MW each bychanging the windings, thus raising the Station capacity
to 132 MW. A rehabilitation programme of Set Nos. 2 to 6 was taken up during
1974-77 to raise the Unit capacity to 25 MW each and Station capacity to 147
MW. Later on Unit No. 1 was also rehabilitated to a capacity of 25 MW in year
1984.
150 MW Bhira Pumped Storage Unit No. 1 commissioned in 1997, raising
Station capacity to 300 MW.
2.3) Hydro Pump Storage Scheme
Another type of hydropower technology is called pumped storage. In a pumped
storage plant, water is pumped from a lower reservoir to a higher reservoir during
off-peak times when electricity is relatively cheap, using electricity generated
from other types of energy sources. Pumping the water uphill creates the potential
to generate hydropower later on. When the hydropower power is needed, it is
released back into the lower reservoir through turbines. Inevitably, some power
is lost, but pumped storage systems can be up to 80 percent efficient. There is
currently more than 90 GW of pumped storage capacity worldwide. The need to
create storage resources to captureand storefor later use the generation from high
penetrations of variable renewable energy (e.g. wind and solar) could increase
interest in building new pumped storage projects.
150 MW pumped storage unit at Bhira hydro station has been commissioned in
1997. The available surplus energy at night can thus be utilised by running the
unit on pump mode to provide economical peaking capacity to the grid during
13. 13
morning and evening peak hours. This is economical and convenient as compared

HYDRAULIC LAYOUT
Here is full hydraulic layout of Bhira generating station from Davdi approach
channel to Bhira power house.
15. 15
The specification and description of main sections of this layout are described
as follows:
3.1) Dams, Lakes, Intake and Tunnels
1. The water for Power generation is taken from the Mulshi lake in Pune
district. A masonry dam in surkhi lime mortar was constructed across the Mula
river at the junction of Mula and Neela rivers, in the year 1926. The catchment
area of the lake is around 250 sq. kms. The length of the dam is 1097 meters.
2. Water from the lake is brought through two Tunnels before entering the valve
house. Screens and intake gates are provided at the mouth of the Tunnels.
During low lake level period, two approachchannels lead the water from lake to
intake. Stop log arrangements are made in the approachchannels to isolate the
intake from the lake.
3. Tunnel No. 1 is partially lined, 4395.545 M long, with a discharge capacity of
49.07 m 3 /Sec (1733.37 cusecs). Tunnel No. 2 is 4555 m long, concrete lined
throughout the length, with a discharge capacity of 56.07 m 3 /Sec. (1980
Cusecs). The important feature of Tunnel No. 2 is that it runs through two hills.
A conduit pipe of 3.96 m diameter connects these two parts. Tunnel No. 2 was
commissioned in 1965. Tunnel No. 2 is used to feed PSU-1. Tunnel No. 2 is
connected to valve house No. 3 through diversion tunnel. On diversion Tunnel,
orifice type surge shaft has been constructed.
3.2) Valve House and Penstocks
1. Tunnels 1 and 2 terminate at valve houses 1 and 2 at Dongerwadi. Each valve
house has six butterfly valves. Tunnel No. 2 is connected to BFV of PSU-1 at
valve house No. 3 thorough diversion Tunnel.
2. Six Penstocks lead the water to the six Units in the Power House. These
Penstocks are connected to both the valve houses (Y-connection). This
arrangement helps in transferring the feed of any Penstocks to either of the
tunnels. All Penstocks have automatic air valves. A stone trap is provided in
each Penstocks between valve house and anchor block No. 17.
3.3) Auxiliary Reservoir
1. Tunnel No. 1 capacity was found inadequate to meet the increased demand
due to addition of set No. 1. Hence Auxiliary Reservoir was constructed at
Dongerwadi in the year. Facility was provided to transfer PenstockNos. 1 and 2
to Auxiliary Reservoir. System off peak periods were utilised to build up the
level in Auxiliary Reservoir to be used during peak demand periods. This
reservoir has a capacity of 227.5 KCM. out of which around 180 KCM can be
16. 16
utilised by draining upto RL 1826 feet. The full supply level is RL 1843 feet 6
inches.
2. After the construction of Tunnel No. 2, Auxiliary Reservoir is used only
during low lake level operation.
3.4)Turbines and Governors
1. Each Unit has two turbines. Each Penstock is therefore bifurcated into two
Penstocks at anchor block No. 7. Individual main inlet valves, operated by water
servomotors are provided at powerhouse end.
2. For each Unit (from Nos. 2 to 6), there are two integrally cast runners (Pelton
wheels) in 13% chromium steel with 18 buckets. The capacity of each runner is
18000 BHP at 440 M head. Unit No. 1 has two runners of 21 buckets each and
has a total capacity of 30,500 BHP. Spear and deflector arrangement acts as
regulating mechanism.
3. Electro-hydraulic type ofgovernors has replaced the fly-ball type governors on
unit Nos. 2 to 6. These governors sense the rate of change of speed along with
change in speed and hence act fast for regulation. (CGL 2005 electronic
governing system has replaced the electro-hydraulic type governor on Unit No. 2
in 1999.)

110KV/22KV LAYOUT
Since generator 1,3,4,6 are supplying to 110KV bus in similar fashion and
generator 2&5 are supplying to 110KV bus in similar fashion. So for the ease of
understanding we have divided the layout in two parts.
4.1) STUDY OF GENERATOR 1,3,4,6
These generators are generating 25 MW at 11KV which is supplied to generating
transformer in between CT, PT and generator protection is provided. Generating
transformers step ups the 11 KV supply to 110KV. The HV sideof this generating
transformers is directly feeding 110KV bus. In between proper transformer
18. 18
protection is provided and a CT is connected for measuring and protection
purpose.
4.2) STUDY OF GENERATOR 2&5
These generators are generating 25 MW at 11 KV. They are directly supplying to
11KV bus section-2 & 11KV bus section-5. In between proper generator
protection (differential protection, field ground fault protection, overvoltage
protection & overheating protection) is provided and in line CT and PT are
connected for measuring and protection purpose. The description of 11KV bus
section is as follows:
4.2.1) 11KV Bus section 2&5
Bus section 2 Bus section 5
a) station transformer 1
b) generating transformer
c) distribution transformer 1
d) BPSU 1
a) station transformer 2
b) generating transformer 5
c) distribution transformer 2
d) BPSU 2
The incomers of these bus sections are generator 2 & 5. Following are the main
feeders of these bus section.
These feeders are provided with proper overcurrent and overvoltage protection
and CT’s and PT are connected for measuring and protection purpose. The
description of these feeders is as follows:
a) Station transformer 1 & 2 :- These transformer are stepping down 11 KV
supply to 440V . And LV side of these transformers is directly feeding to 440V
bus. The description of 440V bus is described further.
b) Generating transformer 2 & 5 :- These transformer step ups the 11 KV
supply to 110KV. The HV side of this generating transformers is directly feeding
110KV bus. In between proper transformer protection (differential protection,
buchholz protection) is provided and a CT is connected for measuring and
protection purpose.
c)Distribution transformer 1 & 2 :- These transformer are stepping up 11 KV
supply to 22 KV. And HV side of these transformers is directly feeding to 22KV
bus. The description of 22KV bus is as follows:
4.2.2) 22KV bus :-This bus is sectioned in three parts bus-1, bus-2 , bus-3.
Bus1 & bus-3are directly fed by HV side ofdistribution transformer 1&3. Proper
19. 19
bus protection (differential current protection) is provided and CT’s and PT are
connected for measuring and protection purpose. The main feeders of this bus
are:
Senior camp
HeadWorks-1
HeadWorks-2
4.3) 110 KV Main & Transfer bus system:
This bus is sectioned in three parts Bus 1, Bus-2 & Bus-3. Bus 1 is fed by
generator 1, 2& 3while bus 2 is fed by generator 4, 5& 6. In normal operation
transfer bus is isolated by circuit breaker and not in operation. Bus 1 & 3 are
continuous via circuit breaker and bus 2 is isolated by circuit breaker in normal
operation.
During fault in bus 1, we can isolate it by circuit breaker connected parallel to
bus 2 and bus 3 will operate normally. Similar operation takes place during fault
in bus 3.
During maintenance of circuit breaker connected parallel to bus 2, we can make
bus 1 and bus 3 continuous by closing the circuit breaker across bus 2.
4.4) Protection equipments : Following are the protection equipments used in
plant-
A) Circuit breaker: All the 110KV circuit breaker are outdoor SF6(sulphur
hexafluoride) type 3150/300 Amps at 145KV insulation level class. In such
circuit breakers, sulphur hexafluoride (SF6) gas is used as the arc quenching
medium. The SF6 is an electro-negative gas and has a strong tendency to absorb
free electrons. The contacts of the breaker are opened in a high pressure flow of
SF6 gas and an arc is struck between them. The conducting free electrons in the
arc are rapidly captured by the gas to form relatively immobile negative ions. This
loss of conducting electrons in the arc quickly builds up enough insulation
strength to extinguish the arc. The SF6 circuit breakers have been found to be
very effective for high power and high voltage service.
Advantages: Due to the superior arc quenching properties of SF6 gas, the SF6
circuit breakers have many advantages. Some of them are listed below:
Due to the superior arc quenching property of SF6, such circuit breakers
have very short arcing time.
Since the dielectric strength of SF6 gas is 2 to 3 times that of air, such
breakers can interrupt much larger currents.
20. 20
The closed gas enclosure keeps the interior dry so that there is no moisture
problem.
There is no risk of fire in such breakers because SF6 gas is non-
inflammable.
The SF6 breakers have low maintenance cost, light foundation
requirements and minimum auxiliary equipment.
21. 21
ANALYSIS OF 440V BUS
The main operation of this 440V bus is to feed the auxiliaries of the plant. This
bus is sectioned in three parts namely Bus-1, Bus-2 and Bus-3. The incoming of
bus-1 is through ST-1 which is fed by generator 2. The incoming of bus-3 is
through ST-2 which is fed by generator 5. An OPH DG set is connected to bus 2
which is for back up purposeand generally not in operation. Two circuit breakers
are connected between bus 1-2 and bus 2-3. In normal operation these circuit
breakers are open so bus 2&3 works separately. If there is fault in Incomer-1 or
incomer-2, then we can operate auxiliaries using DG set by closing circuit
breakers.
For the purposeof balancing energy across this bus, we have visited the location
ofdifferent panels and feeders across 440V bus and pointed out the energy meters
present over feeders and marked the faulty energy meters. The modified EPH
440V distribution layout is as follows:
22. 22
Remarks:
1) During inspection, we have found that energy meters at TOP 1 & TOP 2
need to be calibrated.
Reasonoffault: Proper turn ratio of CT is not entered in Satec energy meter
2)Energy Meters at TAP1, TAP2 & secondary side of lightning transformer 1
are not in service(OFF).
3)Feeders where energy meters are required –
Bus-1 a) 440V ACDB (auto c/o)
b) 110 KV SYRD delta supply
c) AC package unit 1
Bus-3 a) C/R chiller
b) 110 KV SYRD
We have informed authority to provide energy meters at specified feeders.

While Studying the 440V bus, we have notified that there are some feeders
which are either not in use or having negligible energy consumption at bus
section 1 & 3 which are as follows:
at Bus section1 at Bus section3
U#2CLCS
U#3CLCS

Generator strip heaters
Kirloskar compressors

Calculation:
From the table mentioned above, the total energy audit of 24hrs is given
25. 25
Total accountable units in Bus 1 = 3159.1 units
Total non-accountable units in Bus 1 = 42.9 units
Total accountable units in Bus 2 = 2599 units
Total non-accountable units in Bus 2= 139 units
Hence incoming energy and outgoing energy across 440V bus is almost same.
Remark:
From the above calculation we have concluded that there are some feeders
which consumes large amount of energy and we are not monitoring their
readings. So we recommend to install energy meters at following feeders.
Bus-1 a) 440V ACDB (auto c/o)
b) 110 KV SYRD delta supply
c) AC package unit 1
Bus-3 a) C/R chiller
b) 110 KV SYRD
Case study: Since AC unit consumes large amount of energy, hence it is
necessary to account this energy. As we found that the bus-1 feeds AC unit but
there is no energy meter at this feeder. But there is an alternative way to find the
energy consumed by AC unit. Since we can feed AC unit also by bus-3 and
there is an energy meter at this feeder, so by transferring the AC unit load to
bus-3 we can calculate the energy consumed by AC unit.
Result of case study: We have transferred the load of AC unit from Bus-1 to
Bus-3 and the data is as follows:
Reading of day1 =0133 units
Reading of day2 =0133 units
Since meter is showing zero consumption but actually there is consumption.
Hence we suggest to calibrate energy meter at AC unit (Bus-3).
5.2) Suggestions:
1) Generating transformers (1 to 6 in OPH) are designed to have maximum
efficiency at full load. Whereas they are in service on an average 20 hours, but
loaded on an average 10 hours per day. Hence we propose to design these
Generating transformers to have maximum efficiency at half full load while
replacing in the next few years.
26. 26
2) During inspection of 440V bus, we have found that generator strip heater in
bus section-1 was in service. Since this strip heater is generally not in use so it
is operated manually. But it consumes large amount of energy during operation
and manual switching operation results in energy loss. So we suggest its
operation should be made automatic.
3)-To reduce the auxiliary consumption in plant we recommend to control the
auxiliaries using PLC and communicate them with SCADA, which will provide
instantaneous data, and will help us in monitoring every day consumption in
plant.

3MW SOLAR PLANT
This solar plant was constructed under Jawaharlal Nehru National Solar Mission,
which was launched onthe 11th January, 2010 bythe Prime Minister. The Mission
has set the ambitious target of deploying 20,000 MW of grid connected solar
power by 2022 is aimed at reducing the cost of solar power generation in the
country through (i) long term policy; (ii) large scale deployment goals; (iii)
aggressive R&D; and (iv) domestic production of critical raw materials,
components and products,as aresult to achieve grid tariff parity by2022. Mission
28. 28
will create an enabling policy framework to achieve this objective and make India
a global leader in solar energy.
Tata Power Solar commissioned a 3 MW power plant for Tata Power in March
2011 using the cells and modules manufactured inhouse. This is Maharashtra’s
largest grid connected solar power plant built on 13 acres of land with the natural
landscape ofthe site preserved, which continues to attract locals and visitors. The
project was completed in a record time of 9 months and made operational in 2
phases – 1 MW and 2 MW, commissioned in January and March 2011
respectively.
Land area : 13 acres
No of modules : 16,686
Module technology : Crystalline Si, 230 Wp
Inverter : Xantrax 500 kW
SCADA : Schneider
Homes powered : 2 million homes per year
TATA solar power plant, Mulshi consists of total 16,686 modules (55,562 in
1MW & 11,124 in 2MW plant). Each module consists 72 cells (12×6) which
generates 230V, 5.5 Amps, 180 Watts.
18 modules form a string. These strings are connected to SCB (String combiner
box). There are 40 such SCB’s in 1 MW plant and 110 SCB’s in 2 MW plant.
The output of one SCBis 600 V dc, 35-45 Amps. These SCB’s arecombined and
feed to MJB (Main junction box). There are 2 MJB’s in 1 MW plant and 4 MJB’s
in 2 MW plant. The capacity of 1 MJB is 250 KW which are further connected to
inverter each of 500KW capacity. The inverter generates AC supply 315V and
fed it to transformer, which step up 315V to 22KV. The HV side of this
transformer feeds to 22KV HT switchgear which is directly connected to 22 KV
grid headwork.
RooftopSolar:
Rooftop solar is increasingly cost-effective for home owners, business owners,
and their communities. Reductions in technology prices, innovative financing,
and growing networks of solar installers and financial partners all helped drive
down the prices for household systems. The falling price of rooftop PV systems
results from improvements in the technology and economies of scale among
manufacturers. Global solar panel production (for rooftop and other markets)
increased from 24,000 megawatts (MW) in 2010 to 40,000 MW in 2014.
30. 30
The senior camp is fed by 22 KV bus through sub-station transformer which is
22KV/440V step down transformer. The main feeders of sr. camp are:
i. GAWDA, CLUB
ii. TENNIS COURT SIDE
iii. PROJECT GUEST HOUSE
iv. TATA INDICOM
v. STREET LIGHT
vi. VERMA, KALRA
vii. MESS OVEN
viii. DHARMAN, LONHDE, ANEX
ix. RAILKAR SIDE
x. SUSHANT, V. KAMBLE
Remarks:
1. Tennis court consumes large amount of energy as halogen light are used there
but there is no energy meter.
2. All the energy meters used in the camp are analog and outdated which are not
very much accurate. They need to be replaced by digital meters.
7.1) Suggestions:
1. Street lighting is the main source of auxiliary consumption. Though it is
required till 22.30, streets are hardly used after that. Hence we recommend
switching off alternate street lights which could save huge amount of energy.
2. We also recommend to replace street lights with solar street lights.
3. Replace tube lights of the plant with LED’s.
4. Installing rooftop solar for plant, office and households could reduce
significant amount of auxiliary consumption.
5. In walkaway connecting the 110KV SYRD and 220KV SYRD, tube lights are
used for lighting. But in order to save energy, natural light can be used during
day-time.
So we suggest to use transparent glasses on walkaway roof at proper distance
which may save sufficient amount of energy.
6. SQ pump fulfils the requirement of water in camps and continuously in
operation. Continuous operation ofSQ pump is wastage of both water and energy.
So we suggest its operation should be made automatic.
31. 31
8. TAP and TOP consumes significant amount of energy and these are in
continuous operation even when generators are not in operation.
So we suggest to switch off TAP and TOP auxiliary during this period.
9. For the efficient use of energy, awareness program need to be conducted in
Camp-A and Camp-B in a period of 6 months.
