Abstract
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 temperature approaches the thermal stress limit, certain electrical loads are disconnected via a pre-programmed load shed priority schedule, and thereafter loads are re-connected as other loads are de-energized or if the critical hotspot temperature decreases.
