DAY-1
Parvathi Pump House
We have reached Parvathi Pump House around 9pm .With all the safety measures we entered inside the project. The guide has taken the charge and explained us about the project and its main aim.
The Parvati Barrage, also known as the Sundilla Barrage is an irrigation project located at Gowliwada, Peddapalli district in Telangana State.
Sundilla pump house forms a crucial part of kaleshwaram lift irrigation scheme. It serves a conduit between link-1 and link-2 of the lift irrigation scheme. Sundilla pump house stands crucial in diverting flood water of Godavari to Yellampalli and supply them to the entire lift irrigation scheme. Once the water being pumped from Medigadda and Annaram pump houses reaches Sundilla barrage ,it will be pumped out to sweep at the Yellampalli barrage. Sundilla pump house plays an important role in lifting and pumping water from Sundilla barrage to Yellampalli.
Meil and Siemens has executed pump house erection work.
Water drawn from Annaram barrage is stored at sundilla barrage. With the help of sundilla pump house water from here will be lifted to yellampalli barrage.
It will gave 9 pumps and 14 syncronous motors .It is the last pump house in link 1.These pumps lift water to a height of 40 m and discharge 656 cusecs of water into Yellampalli barrage . Each pump of Sundilla pump house requires 40 MW of power. Together all 9 pumps would need 360 MW of power. To facilitate uninterrupted power supply to the pump house a 400 kV substation was built he said.
He said gigantic pumps and motors were procured from Austria and Finland to erect at Sundilla pump house. Godavari river water stored in sundilla barrage will reach the pump house through a 0.80 km gravity canal. Water being lifted by the pump house will reach the delivery point through underground pipes.
DAY-2
Singareni Thermal Power Plant
We have reached Singareni Thermal Power Plant around 10:30am .With all the safety measures we entered inside the project. The guide has taken the charge and started explaining us about the project and its main aim.
The Singareni Thermal Power Plant (STPP) is a coal-fired power station in Pegadapalli, a village in Mancheriyal District of Telangana, India. STPP is extended to 2000 acres of land. The power plant has an installed capacity of 1200 MW, consisting of two 600 MW units with each unit consisting of 10 heaters.
We were taken into the SCADA room and sir started explaining us about the basic principle of generator and about the role of coal in Thermal power generation.
Electricity can be produced at thermo-electric generating stations that burn fossil fuels. Large amount of fossil fuels are burnt everyday in power stations to heat up water, to produce steam which further runs the turbine to generate electricity. The transmission of electricity is more efficient than transporting coal or petroleum over the same distance. Fuel is burnt to produce heat energy, which is converted into electrical energy. Then sir gave a brief explanation of working of Thermal Power Station. The working is mainly divided into four departments. 1.Coal Handling plant, 2.Boiler, 3.Turbine, 4.Generator.
Coal is brought to power station by three means of coal transportation i.e. Roadways, Railways and Ropeways. There are three rollers to grind the coal.
Boiler is a device for generation of steam (530° C to 540° C) for power generation. Steam is sent to super heater where wet steam is converted to dry steam.
Turbine is used to govern and regenerate the feed water heating. There are 3 turbines to reduce overall size when compared to single turbine. Hp turbine is used and it has 543° C temperature and 175 bar pressure. The turbine is directly coupled to the generator rotor and Electricity is generated. Wherever cooling is required it is done with demineralised water
DAY-2
Nandi Medaram pump house
We have reached Nandi Medaram pump house around 9pm .With all the safety measures we entered inside the project. The guide has taken the charge and started explaining us about the project and its main aim.
The Nandi Medaram pump house has seven pumps with 124 MW capacity each to lift two tmc ft water a day. The voltage level at Nandi pump house is maintained by TRANSCO and the discharge of water is maintained by Irrigation department at Nandi pump house. The contract for maintenance is given to Navayuga for 15 years agreement. The operation here at Nandi pump house is similar to Parvati pump but the difference is 120 MW is used at Nandi pump house which is underground pump house whereas 40 MW is used at Parvati pump house which is open pump house. Capacity of Nandi pump house is – 7 pumps each with 124 MW capacity and Lift – 105 M.
