Introduction:
Suleimanya Gas Power Station 1500 MW (SGPS)- Iraq-Kurdistan
Region–Suleimanya
Mass Group Holding contracted the Ministry of Electricity of Kurdistan region –
Iraq, to build Suleimanya Gas Power Station to feed Suleimanya Province with a
capacity of 1.500 MW on Build, Own and Operate (BOO) basis. The site works
started in 2008 through four phases, to reach total production of 1,500 MW.
The Station is located in Chamchemal, west of Suleimany city , 60 km from the
city center.
The plant operates in combined cycle system and consists of four phases. The first
phase is for building the first, second, third and fourth units with a production
capacity of 500 MW. The second phase is for building the fifth and sixth units with
a production capacity of 250 MW, the third phase is for building the seventh and
eighth units with a production capacity of 250 MW, and the fourth phase is for
building the combined cycle station with a capacity of 500 MW, making the total
number of production units 10 units (8 gas turbines and 2 steam turbines) with a
production capacity of 125 MW per gas turbine and 250 MW per steam turbine
with a total capacity of 1500 MW.
The gas turbine units are of the type (F-9E) manufactured by GE Company and
operate on gas fuel mainly and on liquid fuel when needed as well, while the steam
units are of type (C-7) are also from GE Company. All other equipment are from
famous European companies Such as (HRSG from CMI-Belgium, Electrical
equipment from ABB-German Company, ACC ENEXIO Germany, and the gas
system from the Rotring - Germany).
In the combined cycle system, the high heat emitted from the exhausts coming out
of the gas generating units is exploited and passed to (HRSG) boilers that heat the
water to obtain high temperature and pressure steam and pass it to the steam units
for the purpose of producing electrical energy by exploiting the exhaust heat,
which helps reduce thermal emissions and improve the environment without using
additional fuel.

The power station adopts the application of international standards for
occupational health, safety and the environment that are followed globally within
The power generation stations and considers it a priority to maintain the safety of
employees and equipment and pay attention to green areas and afforestation and
increase their areas inside the station.

History of SGPS:
The site works started in 2008 through four phases, to reach total production of 1,500
MW. The Station is located in Chamchemal, west of Suleimanyay city, 60 km from
the city center. The plant operates in combined cycle system and consists of four
phases.
In 2013 MGH – Mass Group Holding Ltd. signed an EPCC contract with ENKA to
convert its Sulaymaniyah Independent Power Project (IPP) from simple-cycle to
combined-cycle technology.
The existing simple cycle Sulaymaniyah Gas Power Station was developed by MGH
– Mass Group Holding Ltd. with a capacity of 1,000 MW with eight GE – 9E gas
turbines.
The combined-cycle gas turbines (CCGT) conversion added 500 MW to the project
making the overall capacity of 1,500 MW, by using steam turbines manufactured by
GE.

What I learned during summer training?
During our summer training in (Sulaymaniah Gas Power Station), we
learned many important lessons in the field of electricity generation and
gathered a lot of new information in the field of power plant operation.
Of course, power plants are one of the most important plants for us
Every developed country with the advancement of technology has many
detailed and important systems for its stations Electricity generation has
been increased, especially) PLC., HMI( and ventilation systems, air
collection, air filtration, oil cooling systems, oil friction reduction, fire
extinguishing systems, turbine systems and The generator system, the
circuit breaker system, then the transformer system and finally through
the transmission line and towers to transmit electricity to the destination
and connect it to the national electricity grid. I learned all these systems
and gathered detailed information about them. Most importantly, we saw
firsthand how all these systems worked.

Gas turbine assembly contains seven major sections:
(1-Air inlet, 2-Compressor, 3-Combustion, 4-system, 5-Turbine, 6-Generator,
7-Exhaust,8-Support system)
Inlet Air system
The air inlet system is the system through which air passes to the compressor. The
principle of operation is that air enters and then passes through an air filter. These
filters clean Fresh air enters the compressor chamber after removing the dust.
About 1,000 tubular and conical filters clean the air. Of course, after a while the
filters need to be cleaned through a system called (pulsation) Cleans the filters.

Auxiliary system
It is a system that helps the turbine consists of several parts such as (crank motor,
gearbox, oil motor, slurry motor)
The crank motor rotates the turbine shaft during starting until the turbine and
combustion chamber start, then the crank motor is separated and turned off.
The gearbox takes rotation mechanically and uses it to send oil to the turbine shaft
bearings.
The oil motor sends oil to the turbine bearings when the mechanical oil pump fails.
There are two types of oil motors, one that runs on AC electricity and the other that
runs on DC electricity.
The Slurry motor starts working when the turbine is turned off and continues to
rotate the turbine shaft until the turbine and generator are completely cooled down.
Then the slurry motor is turned off.

Compressor System
The compressor collects air and increases the air pressure. After the air passes
through the inlet air system, clean air enters the compressor section. In this section,
the air is collected and the air pressure increases after passing through it with 17
stages of compression. The amount of air at the compressor inlet is 1 bar and at the
outlet is about 10 bar.

Combustion chamber
This part is called the heart of the turbine, where an explosion occurs due to fuel,
fire and oxygen. The explosion creates a high pressure, which is applied to the
main turbine, which consists of three stages .This section consists of fourteen
chambers where the explosion occurs. Each chamber has three pipes, one of which
carries air, the second and third pipes carry fuel (diesel and gas). this section, the
temperature reaches about 1127°C, 15% of which is used to heat the steam turbine
boilers.

After a high pressure is generated in the explosion chamber, this high pressure
goes to the turbine. This type of turbine (Frame 9E Gas Turbine) consists of three
stages and the main function is to rotate the generator shaft.

Generator
The totally enclosed, water-to-air-cooled (TEWAC) generator is designed for
operation with air as the cooling medium, although this generator produces 125
MW.The generator is one of the main components of a power plant. After the
turbine rotates the shaft, the generator shaft is connected to the turbine shaft and
the generator shaft starts rotating. Generator consist tow part rotor and stator, First,
DC current is supplied to the stator section of the exciter from the battery or
rectifier. The exciter then creates a magnetic field. This magnetic field causes an
AC current to be generated in the exciter rotor. Through the armature, the AC
exciter is converted into DC and fed to the generator rotor. A magnetic field is
created in the generator rotor and as the shaft rotates, it causes electricity to be
generated in the stator of the generator AC wind from the generator goes to the
AVR system DC electricity output It must go to the section of the Executioner, the
Battrey must be cut off.

Some other types of generators work with the PMG (pure magnetite Generator)
system, which works as follows: First, the pure magnetite generator produces (50
volts, 6 amps), then this amount goes to the stator section of the exciter, then the
exciter due to The rotor section produces (1,200 amps and 200 volts of AC), This
amount then enters the rectifier or AVR, converts it from AC to DC and fields it to
the rotor section of the main generator. The main generator then produces (15 KV,
5,000 Amps, and 125 MW).

16. 16
Cooling system
During operation, the temperature of the combustion chamber, turbine and
generator rises very high, so oil is used to cool them. Of course, the temperature
of the oil rises, so we use water to cool the oil, then temperature The rising water
temperature is sent to a cooling system where the water temperature is lowered
by fans It is called a heat exchanger. It is prepared for use as a closed circuit.

17. 17
Exhaust system
A turbine rotates air or waste gas under high pressure. When this air is formed by
combustion and passes through the turbine and generator, the temperature is high.
Of course, after rotation of the turbine, it must be expelled through a part called an
exhaust. But, in this power plant, this high temperature air is used to heat water to
produce steam for a steam turbine, which is called a steam turbine, in this station
have tow steam turbine 250MW.

Circuit Breaker
After producing 15 kV, this amount of electricity goes to the circuit breakers. The
main function of the circuit breakers is to cut off the power circuit when necessary
or repair, as well as in the event of a short circuit high or low voltage and
frequency will be cut off electrical circuit to protect generators.in this power plant
have three type of circuit breaker 1-high voltage circuit breaker (15kv), 2-miduim
voltage circuit breaker (6.6kv), 3-low voltage circuit breaker (0.4kv).this power
plant depend on CB-SF6.

19. 19
Transformer
Transformers raise or lower the voltage. A transformer consists of a primary coil, a
secondary coil, and an iron core when we want to send electricity to a distant place
or city A transformer is needed to raise the voltage and reduce the amperage In the
city center, we will need transformers to lower the voltage and raise the amperage
In this this power plant have three type of Transformer first main transformer is
step up and convert 15KV to 132KV, second medium transformer is step down and
convert 15KV to 6.6KV, third low transformer convert is step down 6.6KV to
0.4KV.

Control Center Room (CCR)
Control Center Room In this room we can monitor and control all the systems in
the power plant through HMI, SCADA systems and PLC programs. All parts of the
power plant have special sensors that provide data and information Transfer to the
control center room as well as the staff of this room They can control the engine,
fans and doors and the alarm system alerts employees in case of any fault.

Steam turbine
Within the combined cycle arrangement the gas turbine is still the heart of the
power generation system. Power is produced in much the same manner as in the
simple cycle mode, but the hot exhaust gases are routed to a heat recovery boiler
where they are used to raise pressurized steam. This steam is then passed to a
conventional steam turbine-generator where the energy is converted into electrical
power.
There are several different arrangements of combined cycle plants, ranging from
single unit stations, to multiple units arranged to feed a common steam turbine-
generator. The steam and gas turbines may be either mounted on the same shaft
to drive a common generator, or be completely separate machines with individual
generators in different areas of the plant. With a fuel-to-electricity efficiency as
high as 60% in some cases, the combined cycle arrangement is the most
commonly used gas turbine based power plant in recent years. A variation of the
arrangement known as the combined heat and power plant is also widely used in
the industry, where a user requires large quantities of electricity,

plus steam for heating or process use. This offers a further improvement in
overall thermal efficiency with a subsequent saving on plant fuel costs.
In combine cycle there is gas turbine which produces electricity but it is heat and
smoke won’t be wasted instead of that goes in to HRSG and from another side
water goes in to make a steam that is used to rotate a steam turbine ,the water
comes from Goptapa then goes through a filtration and goes to a demine tank
collection then it goes to these places saws area HRSG1,2,3,4,cct emergency filling
,Acc spray , hydrogen generator, expansion tank, chemical building.
From cct goes to pumps which there is a strainer between cct and the pump then
it go to a desecrator which makes the water a bit hotter and it also used to
produce vacuum then it goes to a gland steam which makes it a bit hotter too and
it’s job is to seal but while returns before venting it used for that purpose then
goes to boiler into pre heater then into desecrator then in to BFP pumps then to
hp economizer 1 and Lp economizer after that in to hp economizer 2 then into hp
drum and lp drum after that they go to their evaporators and back to drum then
go to super heater then into lp and hp steam turbines then in the end of turbines
it returns to ACC then into cct.

When the high temperature air leaves the gas turbine it goes to the steam turbine so
the exhaust air of four gas turbines is used for one steam turbine which means eight
turbine units versus two steam turbine units. 2*250MW=500mw steam turbine.

24. 24
ACCs work well in water-scarce areas:
Air cooled condensers are used for thermal power plants like
combined cycle, concentrated solar, coal, biomass, and waste to
energy. Since these kinds of power plants, which are equipped
with ACCs, do not require a large volume of cooling water, the
power plants can easily be built in a region where water may not
be available, or where its use is restricted or expensive.

25. 25
Switch yard and towers
After generating 15 kV by the generators and then increasing it to 132 kV by the
transformers, the amount of electricity produced goes to the switch yard it consists
of the main load, circuit breaker and disconnector and the bus section, each
generator unit First it goes to the circuit breaker and then it goes to two
disconnectors. Each disconnector is connected to a bus bar. Each unit is connected
to a bus section and all the parts connected with ground, this step is called input.

The second part is called the output line. The power of all the units goes to
the bus bars and then from the bus bars to the two disconnectors and then the
electricity goes to the circuit breaker and the electricity goes to another circuit
breaker called QB9 and then powers the towers it will be sent to the destination
and connected to the national electricity grid.
In this power station have 7 towers to send out electrical power each tower consist
2 line three phase It’s mean 14 line, the objectives are divided as follows: 2 line for
chamchamal town, 2 line for Qularaisi, 6 line for Bzian, 2 line for BardaQaraman,
2 line for still factory.
