  • Method, apparatus, and system for real time reactive power output monitoring and predicting
    Patent number: 6492801
    Abstract: An actual real-time reactive power output reserve of a generator is calculated by determining a real-time reactive power output of the generator at present operating conditions, determining a maximum reactive power output of the generator at the present operating conditions based on a maximum volt-ampere output capability of the generator, a real-time transmission voltage level of a transmission system connected to the generator, and a real-time maximum acceptable generator terminal voltage, and subtracting the real-time reactive power output from the maximum reactive power output.
