Description
Generators for hydropower, from micro hydro plants to stations with a capacity of several megawatts, are produced by the manufacturer’s division. The range includes synchronous generators up to 10 MVA at 380–13,800 V with up to 32 poles, slow-speed asynchronous generators up to 700 kW and D2G permanent-magnet generators up to 500 kW, which operate at constant rotational speed without an inverter. The rotational speed from 187 to 1800 rpm is selected individually for the turbine and the drive system. According to the manufacturer’s brochure, typical combinations are: at 187–600 rpm, 90–700 at 12–24 poles; at 187–1800 rpm, 485–5600 at 4–32 poles; at 300–429 rpm, 110–330 at 14–22 poles (the brochure gives the graphs in MW for 60 Hz and MVA for 50 Hz). Generators are designed for a specific project: at the customer’s request the cooling method (air or water, with a separate cooling circuit), bearings (ball, roller, sliding, insulated, for vertical and high axial loads), degree of protection, mounting arrangement (horizontal or vertical) and couplings can be changed. For harsh conditions, closed bedplates, protection against corrosion and humidity, and additional ProtexPlus coatings are provided. Insulation is class H with vacuum-pressure impregnation (VPI); medium- and high-voltage machines use the HVi insulation system, designed for voltages up to 15.75 kV. Regulation is by digital regulators with site-specific settings, built-in protections, an APO function for eight alarm parameters, load control and fault recording. Bearing and winding temperature sensors, vibration sensors, heaters, current transformers and over-excitation protection are available. According to the manufacturer, the company has more than 70 years of experience in manufacturing hydro-generators, and many of its machines operate at stations in Europe and beyond. The generators are built to international standards and can be adapted to specific environmental and operating requirements. Applications: small and micro hydropower plants, diversion and run-of-river stations, refurbishment and replacement of generators at existing stations, installations on water conduits and in water-supply systems. Separately, the manufacturer produces permanent-magnet generators of about 100 kW for wind turbines.
