Description
Hydro-generators are synchronous generators for small and medium hydropower plants, operating together with Pelton, Francis and Kaplan turbines. In 2009 vertical hydro-generators were developed jointly with Voith (Germany). The parameters of each machine are selected to suit the turbine type, grid requirements and powerhouse conditions. According to the catalogue, the hydro-generators cover a range of 1–40 MVA (advertising materials also cite a range up to 70 MVA), voltage up to 15 kV, frequency 50 or 60 Hz and rotational speed 187–1800 rpm. Design is horizontal or vertical, with a salient-pole or non-salient-pole rotor. Excitation is brushless or static, with a permanent-magnet pilot exciter (PMG) and slip rings possible. Bearings are rolling or sliding, degree of protection IP23–IP54, the cooler is located on top, at the bottom or at the side, output leads come out from the side or top, and the shaft end is cylindrical or flanged. The catalogue highlights features of hydro-units. When the runner is mounted directly on the generator shaft, precise machining of the output shaft end is required, which is carried out in the manufacturer’s own machining shop. The hydrostatic column creates large bearing loads, so special oil lubrication and a reinforced design are used. If the guide vane mechanism fails, the unit can accelerate to runaway speed, roughly three times the rated speed; the generator is designed with a margin of mechanical strength and careful balancing for this case. These hydro-generators are aimed at stations in remote areas with difficult grid conditions, where flexibility of electrical design and long service life are important. Production takes place in Bangalore (India) and Gebze (Turkey); stator and rotor manufacture is in-house, with robotic core lamination, automatic coil insulation, global vacuum-pressure impregnation and fully automated test benches for horizontal and vertical machines. Design conforms to IEC, NEMA and JIS.
