Motor-generator technology by Voith – including excita- tion, static frequency converters (SFC) and SCADA systems.
Well advanced and proven VPI insulation system for optimized design for Class 155 according IEC (formerly Class F) and voltages up to 27 kV.
Motor-generators are air-cooled by RIM-Ventilation or forced ventilated or direct water-cooling of stator or stator and rotor windings and also stator core.
Magnetic thrust bearings for reduced torque during pump starts and reduced bearing losses during normal operation.
Comprehensive system for automation of power station complex as a whole including monitoring, remote supervisory control and data acquisition of the plant with fiber optic cable as required, for control and station networks.
Static frequency converter systems composed of computer duplex digital controller and optical thyristor of high resistance voltage for high performance and easy maintenance.
With the use of an asynchronous motor-generator the rotational speed of the pump-turbine can be varied. Thus, the pump capacity can be adjusted to using just the currently available amount of energy. This allows for a highly efficient stabilization of the grid.
