NTPC Ramagundam, a part of National Thermal Power Corporation, is a 2600 MW Power station situated at Ramagundam in Peddapalli district in the Indian state of Telangana, India. It is the current largest power station in South India. It is the first ISO 14001 certified "Super Thermal Power Station" in India.
The TG Hall or the Turbo-Generator hall or the Turbine-Generator Hall is the hall or space where the turbine-generator sets are present.
NTPC Ltd., Ramagundam has two TG Halls one for STAGE-I and the other common for STAGE-II and STAGE-III. These TG halls are equipped with heavy overhead cranes that assist in transportation of material within the TG hall. These cranes find their use greatly during overhauls.
The whole plant is divided into 3 stages, each stage being planned at one time.
This stage consists of three units(Unit-1, Unit-2, Unit-3) each with a generation capacity of 200 MW. The turbines for these three units were manufactured by The Ansaldo Energia Ltd. The construction began in the late 1970s and these units have performed well over a long period setting many records regarding maintenance and generation over the other two stages.BUT stage (1,2,3) cwp motors are manufactured by BHEL. and all motors are manufactured by Ansaldo. S-I coal mill motors are 240 KW and PA fans are 400 KW. All equipment is very important in plant.
This stage again consists of three units (Unit-4, Unit-5, Unit-6) each with a generation capacity of 500MW. The turbines for these three units were manufactured by Bharat Heavy Electricals Limited(BHEL).
This stage comprises only one unit (Unit - 7). This is a first of its kind in South India being a computer operated unit. A wide disparity may be seen between the control rooms of the other two stages and this computerised unit. To this day, many Power plant engineers train in this unit to upgrade themselves to this new mode of operation. This unit also has the tallest chimney in India (height: 275 metres).
Once in two years, these units are stopped and overhauled, one unit at a time. The overhauls are usually taken up during the months June to September as the monsoons activate hydel power generation which substitute the power generation lost due to the overhaul of the unit. The same practice is followed all through the country. The overhauls usually take 15 to 20 days per unit provided there is no major repair involved. Major repairs include turbine casing,turbine rotor damage and other damages that require transporting the equipment to another location(usually the manufacturer). The overhauls are the dissipators of the annual PLF of any power plant.
