System and method for reactive power compensation

摘要

A reactive power control system is provided. The reactive power control system computes a required value for a reactive power based on a state observer method for at least one electrical element in an electrical system. The reactive power control system also generates a reactive power command based on the required value of the reactive power. The reactive power control system further transmits the reactive power command to the electrical element in the electrical system for generating the required value of reactive power to compensate for a voltage change induced by the respective electrical element in the electrical system.

1. A reactive power control system for executing steps of:
computing a required value for a reactive power based on a state observer method for at least one electrical element in an electrical system; generating a reactive power command based on the required value of the reactive power; and transmitting the reactive power command to the electrical element in the electrical system for generating the required value of reactive power to compensate for a voltage change induced by the respective electrical element in the electrical system, wherein the reactive power control system includes a state observer module for executing the step of computing the required value of the reactive power by obtaining voltage and active power signals of the at least one electrical element and using the voltage and active power signals for determining sensitivity coefficients to be used in the state observer module for calculating the required value of the reactive power.
