Clean source of energy is playing very vital role in today’s eco-friendly environment. Potential
energy available with water can be converted into useful work by maintaining the purpose of clean environment.
Hydro-power plant utilises the energy of water and can produce equivalent mechanical output. Hydro-electric
power plants are much more reliable and efficient as a renewable and clean source than the fossil fuel power
plants. The rivers in Western Maharashtra region flows from Sahyadri mountain towards Deccan platue with
steady gradient. In recent years, the environmental impacts are becoming difficult for developers to build new
dams because of opposition from environmentalists and people living on the land to be flooded. Therefore the
need has arisen to go for the small scale hydro power plants in the range of mini (few MW) and micro hydro
(kW) power plants. This paper discusses the conceptual design and development of a micro hydro power plant.
The developed model can be used at sites having head range of 0.5 to to 6 m. The required information was
collected from meteorological department and irrigation department of Kolhapur division of Government of
Maharashtra, India.

Designing Of Permanent Magnet Synchronous Machine For Applications In Small H...IJERA Editor
The need of the hour, as we all genuinely know from the global scenario is the production of electricity from the renewable resources of energy. Most widely used among them are the solar and the wind potential. Besides these, the hydroelectric resources also play a remarkable role as hydroelectricity accounts for a major share in the energy sector throughout the world. The trend at present is of the stand alone hydro power plants wherein the turbine used is the Hydrokinetic turbine , which works with the speed of flow of the water stream. Permanent magnet synchronous machines, known for their robust nature, variable speed, and high power to weight ratio are the most suitable ones for the construction of the turbine for low speed operation. This paper presents the design of permanent magnet synchronous machine and the machine has been modeled and simulated in RMXprt and Ansys Maxwell.
Crossflow turbine design specifications for hhaynu micro-hydropower plant, Mb...dngoma
Micro-hydropower plants are very applicable in rural and off-grid areas where water resources become available. This is because they can be installed with fraction of the cost as compared to large hydropower plants or even grid extension. Also in rural and off-grid areas, the population density is small and very sparsely distributed which makes it un-economical for the development of large electricity supply projects. In this case
the mini and micro energy projects are the suitable technology to be used to supply power to the consumer load demand in the rural and off-grid areas. One of the sustainable ways to do is to use the available water resources like small rivers to develop micro-hydropower plants. The effective use of water from local rivers to develop micro-hydropower plants have proven to be sustainable way of electricity generation. But despite all these positive outcomes, studies have shown that many of the available rural areas micro-hydropower potential sites are facing reduced water volumetric flow due to irrigation activities and also lack high site heads due to the nature of the landscape. In this case, the development of a micro-hydropower for electricity generation is limited to specific type of hydro turbine technology called crossflow turbine. This is because this type turbine technology can accommodate wider range of flow discharge and head values in the micro and mini scale of hydropower technology range. The crossflow turbines can also be manufactured locally and adapted to the local rural environments and also have been proven to be very robust with less operational and maintenance costs. Thus why there is a need to customize this technology in the local rural area in terms of turbine design in order to standardize the local manufacturing and this is the main motivation that this design study have been addressing.

Design, Modeling & Analysis of Pelton Wheel Turbine BladeIJSRD
A Pelton-wheel impulse turbine is a hydro mechanical energy conversion device which converts gravitational energy of elevated water into mechanical work. This mechanical work is converted into electrical energy by means of running an electrical generator. The Pelton turbine was performed in high head and low water flow, in establishment of micro-hydroelectric power plant, due to its simple construction and ease of manufacturing. To obtain a Pelton hydraulic turbine with maximum efficiency during various operating conditions, the turbine parameters must be included in the design procedure. Here all design parameters were calculated at maximum efficiency by using MATLAB SOFTWARE. These parameters included turbine power, turbine torque, runner diameter, runner length, runner speed, bucket dimensions, number of buckets, nozzle dimension and turbine specific speed. The main focus was to design a Pelton Turbine bucket and check its suitability for the the pelton turbine. The literature on Pelton turbine design available is scarce; this work exposes the theoretical and experimental aspects in the design and analysis of a Pelton wheel bucket, and hence the designing of Pelton wheel bucket using the standard rules. The bucket is designed for maximum efficiency. The bucket modelling and analysis was done by using SOLIDWORKS 2015. The material used in the manufacture of pelton wheel buckets is studied in detail and these properties are used for analysis. The bucket geometry is analysed by considering the force and also by considering the pressure exerted on different points of the bucket. The bucket was analysed for the static case and the results of Vonmises stress, Static displacement and Factor of safety are obtained.
Prospect of Small Hydro Power in Uttarakhandijsrd.com
Uttarakhand is riched with natural renewable resources for generating electricity. As we know that Uttarakhand is about to fully hilly areas. Due to the fully hilly regions, the hydro power available in Uttarakhand can be harnessed by installing the small hydro power plant. The estimated potential of this state for small hydro power plant is more than 1708 MW. The installed capacity of small hydro power is 174.82 MW and under implementation capacity is 174.04 MW. Therefore in this state a large amount of small hydro power is yet to be harnessed by the small hydro power plant. Uttarakhand has a large network of rivers and canals which provides an immense scope for hydro power energy. In India, the Development of Small Hydro Power Projects was started in the year 1897. In India, the first hydro power station was a small hydro power station of capacity 130 KW commissioned at Sidrapong near Darjeeling in West Bengal in 1897.
Runner profile optimisation of gravitational vortex water turbine IJECEIAES
This study discusses the numerical optimisation and performance testing of the turbine runner profile for the designed gravitational water vortex turbine. The initial design of the turbine runner is optimised using a surface vorticity algorithm coded in MATLAB to obtain the optimal stagger angle. Design validation is carried out using computational fluid dynamics (CFD) Ansys CFX to determine the performance of the turbine runner with the turbulent shear stress transport model. The CFD analysis shows that by optimising the design, the water turbine efficiency increases by about 2.6%. The prototype of the vortex turbine runner is made using a 3D printing machine with resin material. It is later tested in a laboratory-scale experiment that measures the shaft power, shaft torque and turbine efficiency in correspondence with rotational speeds varying from 150 to 650 rpm. Experiment results validate that the optimised runner has an efficiency of 45.3% or about 14% greater than the initial design runner, which has an efficiency of 39.7%.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Abstract: Clean source of energy is playing very vital role in today’s eco-friendly environment. Potential
energy available with water can be converted into useful work by maintaining the purpose of clean environment.
Hydro-power plant utilises the energy of water and can produce equivalent mechanical output. Hydro-electric
power plants are much more reliable and efficient as a renewable and clean source than the fossil fuel power
plants. The rivers in Western Maharashtra region flows from Sahyadri mountain towards Deccan platue with
steady gradient. In recent years, the environmental impacts are becoming difficult for developers to build new
dams because of opposition from environmentalists and people living on the land to be flooded. Therefore the
need has arisen to go for the small scale hydro power plants in the range of mini (few MW) and micro hydro
(kW) power plants. This paper discusses the conceptual design and development of a micro hydro power plant.
The developed model can be used at sites having head range of 0.5 to to 6 m. The required information was
collected from meteorological department and irrigation department of Kolhapur division of Government of
Maharashtra, India.

I. Introduction
The power generating capacity in Western Maharashtra from small and mini hydro is currently 1,100
MW (approx.) and is growing at rate of approximately 150 MW per year whereas 3300 MW of capacity is
expected to be generated in 10 years. Most of this production will be from government power production,
provincial/municipal utilities, and remote communities.
For the last twenty years, provincial and or municipal utilities, and remote communities have been increasingly
interested in developing small hydro, generally with plant capacities less than 5 MW. Most of these small hydro
plants serve as decentralized power, connected to local grids. Total annual installation of small hydro plants in
Maharashtra increased from a capacity of 10 MW/year in mid-eighties to approximately 20 MW/year for the last
few years.
There is significant availability of potential in small and medium hydro plants in Western Maharashtra.
A large number of these sites are called as ultra-low-head or run-of-river, which do not require large reservoirs
or dams, run on a special type of irrigation weir called Kolhapur Type Weir (K.T.Weir). Most of these hydro
sites serve as decentralized power stations. The power produced from these plants can be utilised for drinking
water supply schemes, to help keep the rural hospital running normally, to lit up the street lights at night time.
[1, 2]
However, the further development of micro to small hydro will largely rely on efficient and lower up-
front costs involved in the emerging technology which can prove a cost effective solution village panchayat and
Samity. While world-wide High head hydro potential is vast (thousands of suitable existing dams), the
development of this potential is very low due to its high development cost, particularly for the related civil
works which represent 40-50% of the total development costs of any given project. [3]
This paper presents a prototype model of ultra-low head hydro power turbine, designed specifically for
very low head sites (1.4 to 3 meters net head) in Western Maharashtra region. The objectives of the design of
the ultra-low head hydro power turbine is to develop a unit that will require very few civil work, will be easy to
install and will offer a high degree of reliability at a reasonable cost per installed kW.
II. Methodology
1) The first stage of the study is to recognise the principles of extracting power from a water source. This
continued with the investigation into an understanding of the current technology, identifying the sites,
finding the literature and the components required to complete a hydro system (includes the study of
various types of turbine and mechanical plant) [3]
2) Several visits to the proposed sites were made, and the sites were photographed and surveyed with the help
of Survey maps, to gain an understanding of the lay of the land.(Fig. 1)
3) As there is no monitoring equipment on the waterway historical flow rates, rainfall data from the

Meteorological Office, weather station nearby was used in conjunction with the Survey maps to calculate
the volumetric flow rates for the site.
4) The data of water discharge from the Dams is collected from the irrigation department office at district
level, as the control is purely in the hands of district collectors.
5) Further an enhanced model of simple reaction water turbine was developed and manufactured for optimum
turbine sizing of ultra-low head. [4, 8]
6) After the prototype building, attempts were made to improve the turbine performance by minor or major
design modification. [6,7,8,9]

trials)
Specification of selected site:
Continuous flow of water throughout the year as it is located very near to Dhudhaganga Tunnel
&provides a flow rate of 43 m3
/sec. The difference between upstream and downstream is near about 3 m.
III. Calculation Of The Main Characteristics
The main characteristic is the data on which the design of the runner is based. To calculate, for
instance, the forces on the blade or to determine the dimensions of the adaptation mechanism the characteristics
of the turbine are needed.
In figure 2, a sketch of a propeller turbine is given. On this sketch, those heads and points which play a
significant role in this paper are marked.
3.1) Power
The power of the runner can be calculated with the following equation:
P = Q*H* ηh * g * ρ [W] (1)
Where: Q-discharge [m3
/s], H-gross head [m], ηh-hydraulic efficiency, ρ-water density [kg/m3], g-
acceleration of gravity [m/s2
]
The site where the experimental rig of the turbine is built, provides a maximum gross head of 0.75 m.
An efficiency of 0.8 can be assumed for a propeller turbine. Taking a discharge of 0.015 m3
/sec, the power of
the runner is 70.49 W or 0.0704 kW

3.2) Speed of the turbine
3.2.1 Specific speed
The different types of water turbines can be classified by their specific speed. The specific speed is a
dimensionless parameter and characterizes the hydraulic properties of a turbine in terms of speed and discharge
capacity; it is based on similitude rules. The specific speed is defined as:
4
3
n
s
H
Qn
=n
(2)
Where: Net head [m], Rational speed of the turbine [min-1
]
The specific hydraulic energy 5.89 of machine can be established with the following equation:
gH=E n
[J/kg] (3)
Therefore, H n = 0.6 m (4)
Due to statistical studies of schemes, F. Schweiger and J. Gregory established the following correlation
between the specific speed and the net head for propeller turbines:
nQE=
2.294
H n
0.486 (5)
Since the rotational speed is unknown, the specific speed has to be calculated with the formula (5).
Hence, a resulting specific speed (ηQE = 2.94 /sec and therefore rotational speed = 982 rpm )
3.2.2 Runaway speed
The runaway speed is the maximum speed which the turbine can theoretically attain; it is achieved
during a null condition. Referring to standards of propeller, the following guidelines given in table 1 can be used
to determine the runaway speed.

coefficient = 2553 rpm

The design of the blade in figure 2.does not just depend on the stress analysis but several other factors
also play a significant role. The leading edge is kept thicker than the trailing edge for a streamlined flow and
also to reduce the vibrations. This is incorporated in blade, by making it thicker near the flange and thinner
towards the tip. In addition that, the blade has curved to take an advantage of the tangential velocity.
2) Development of Runner
The runner is the rotating part of the turbine, which includes the hub, blades and shaft. Casting from
metal is probably too expensive except for mass production. Since this is a prototype building, the runner parts
are developed by conventional manner. Some of the machine tools which are used to produce are portable
grinder, general purpose lathe to machine shafts, hub, and welding machine to fabricate etc. The developed
runner is shown in figure 3.
Figure 3: Runner
3) Development of draft tube
Draft tube is a long conical shape tube used to recover the kinetic energy at exit of turbine is shown in
figure 4.
Figure 4: Draft Tube
4) Development of vanes
Guide vanes are used to give the flow, approaching the turbine blades, an initial swirl or tangential velocity
component. The turbine blade changes the tangential velocity component of the flow, and it is this change, in
tangential momentum, that produces the torque which further gives us mechanical output. Figure 5 shows the
guide vanes.

V. Conclusion
The main objective of this paper is to focus on the potential of micro hydro power development and to
understand the designing procedure of a ultra-hydro system.
This paper deals with developed prototype model, at very low cost. The design of 0.2 kW developed
using ultra-hydro plant prototype model can benefit to harness the unidentified hydro power potential which is
available at K. T. weir (Kolhapur Type weir). The available hydro power potential can be used to supply and
fulfil the demand of domestic water of nearby villages, for lightening the roads near K. T. weir.
