Description
The manufacturer produces synchronous generators for hydraulic turbines, from high-speed machines for Pelton turbines to low-speed multipole generators for Kaplan turbines. For low-speed machines the manufacturer specifies a series of 4000–25 000 kVA at 150 rpm and voltages up to 15 kV. The generators are specially optimized for the hydro unit: the rotor and bearing assemblies are calculated for the turbine runaway speed and for the forces transmitted from the turbine. The design and excitation are the same as in the other synchronous generators of the manufacturer: a compound system or a PMG exciter with analog or digital regulation, generator protection on request, VPI insulation, symmetrical ventilation, accessible and quickly replaceable exciters, and adaptation to existing foundations during station reconstruction. Delivery examples: a generator of 15 000 kVA, 1000 rpm (runaway 1800 rpm), weighing 43 t, for an underground hydropower plant with Pelton turbines; a generator of 8225 kVA, 600 rpm (runaway 1080 rpm), 44 t, for a hydropower plant with a Pelton turbine; a generator of 3918 kVA, 273 rpm (runaway 720 rpm), 58 t, for a hydropower plant with a Kaplan turbine. The product is suitable for reconstruction of small and medium hydropower plants where the generator is replaced while the foundation and turbine are kept, as well as for new diversion-type stations. It is an analogue of medium-power hydrogenerators of the SV, VGS and GSV series.
