Control of the gas-cooled rotor winding of generators to a constant temperature by temperature-dependent control of the cooling gas pressure

摘要

The invention relates to a control of the gas-cooled rotor winding of generators to a constant temperature by temperature-dependent or load-dependent control (open loop control) of the cooling gas pressure. The invention brings a significantly reduced thermo-mechanical stress on the rotor winding with it, since the rotor winding is largely driven at a constant temperature.
