Voltage regulator and methods for simulating reactive power in parallel power generation systems

摘要

Systems, methods, and a voltage regulator are provided for tuning reactive droop compensation of a generator in a parallel power generation system. The voltage regulator is configured to compute a simulated droop compensation voltage for the generator and control an excitation signal to the generator based at least in part on the simulated droop compensation voltage.

1. A voltage regulator for tuning a reactive droop compensation of a generator in a parallel power generation system, said voltage regulator comprising a processor configured to:
receive a measurement of an output voltage of the generator from a voltage sensor and a measurement of an output current of the generator from a current sensor; calculate apparent power output by the generator based on the measurements of output voltage and output current; calculate reactive power based at least partially on the calculated apparent power; compute a simulated droop compensation voltage for the generator based on the calculated reactive power; and generate an excitation signal to drive excitation current into a generator exciter for driving the generator based at least in part on the simulated droop compensation voltage.
