Description
For hydroelectric power plants the manufacturer supplies generators of various scales. These are small run-of-river plants, medium reservoir stations and large pumped-storage plants. Hydro generators are designed individually for each project and built at the plant in Dresden. This plant has made generators for hydropower since the early stages of its history, and among the manufacturer's achievements is the creation of the first hydro generators in Germany.
The manufacturer presents all these options as standard for its hydro generators. The machines are made with a horizontal or vertical shaft arrangement, in an open or closed enclosure, with air or water cooling. By type they are synchronous generators built to a project. Specific power ratings, voltages and speeds are not given on the manufacturer's website; they are set by the technical specification for the station.
The windings have their own VEMoDUR-VPI insulation system. It keeps high thermal and electrical resistance even when the environment is harsh. The machines are rated for continuous duty, and the design is optimized for efficiency so that at every meter of head the station delivers more energy to the grid.
The open version is cooled by air passing through the machine, while the closed one has a closed cooling circuit. A horizontal or vertical shaft arrangement is chosen to suit the layout of the unit and the type of turbine. A closed enclosure is appropriate where the machine hall has a lot of dust or moisture, while an open one is simpler to maintain. Non-standard cases are also made to order. This concerns unusual dimensions, cooling schemes and connections. It is needed, for example, at stations with large fluctuations of water flow or where the machine hall has little space.
The manufacturer supports the project from calculation and design through manufacture to commissioning and service. Generators are supplied both for new stations and for modernization of existing units, when old machines are replaced. The wider portfolio includes synchronous, induction and permanent-magnet generators. For small hydropower plants, induction generators of the G2.R, GE.R and G4.R series up to 710 kVA are also used; they are listed as a separate catalog item.
