초록

In response to the loss of a generator in an electrical power system, all operating electrical loads are automatically switched to a second generator, and the electric power system continues to provide power to all of the loads. The total power required to operate all operating loads is permitted to exceed the nominal rated capacity of the operating generator, and the winding temperature or other critical hotspot temperature of the operating generator is monitored to determine whether thermal stress limits will be exceeded. If the critical hotspot temper...

청구항

An electrical power system comprising: at least two generators; means for providing a generator trip signal in response to a generator failure; temperature sensing means for providing temperature signals each indicative of the temperature of a generator critical hotspot for a corresponding operating generator, said generator critical hotspot being indicative of the generator internal component whose temperature first reaches its thermal limit in response to increasing generator load; means responsive to said temperature signals for providing rate signals...
