Description
Turbogenerators for steam turbines are synchronous alternating-current generators that the company produces at its plants in Bangalore (India) for power stations and industrial cogeneration installations. The range covers 1 to 250 MVA: machines up to 68 MVA are of the manufacturer’s own design, while 2-pole generators of 75–250 MVA are built under a licence agreement with a European manufacturer signed in 2012. The generators are rated for continuous S1 duty and base load. Typical customers are captive power plants of cement, sugar, metallurgical, paper and chemical plants, and biomass stations; the generator runs in parallel with the national grid and feeds surplus power into it. The manufacturer notes special rotor designs that can be adapted to different site conditions and compliance with current IEC standards. Main catalogue parameters: voltage up to 15.75 kV, frequency 50 or 60 Hz, rotational speed 1500/1800/3000/3600 rpm. Cooling system: TEWAC (air–water), TEAAC (air–air) or DAC (open air), with the cooler located on top, at the bottom or at the side. Degree of protection from IP23 to IP56, rolling or sliding bearings. Excitation is brushless or static; a permanent-magnet pilot exciter (PMG) and slip rings are available. Output leads may come out from the side, top or bottom or go to a separate cabinet, and the shaft end is cylindrical or flanged. Versions for hazardous and ordinary areas are available. Stator and rotor are manufactured in-house: robotic core lamination, automatic coil insulation, global vacuum-pressure impregnation (GVPI), and balancing with overspeed testing above rated frequency. Before shipment each machine passes factory tests, including high-voltage tests and partial discharge measurement. Applications: steam-turbine plants of thermal power stations, combined heat and power plants and waste-to-energy plants, heat recovery, biomass and geothermal power (for geothermal stations: outdoor installation and hydrogen-sulphide purge systems). Generators with non-standard voltage and frequency are produced to customer specification. Design conforms to IEC, NEMA, API and JIS.
