COORDINATED CONTROL METHOD OF GENERATOR AND SVC FOR IMPROVING POWER PLANT ACTIVE POWER THROUGHPUT AND CONTROLLER THEREOF

摘要

The present invention provides coordinated control methods of generator and SVC for improving power plant active power throughput and controller thereof. The method comprises: measuring the required input parameters for the generator and SVC control; judging the system topology and the control mode of SVC to determine the operation mode; and calculating the control reference based on the operation mode to control the generator and/or SVC. The proposed methods and coordinated controllers enable the SVC to share the required reactive power output of the power plant, convert the generator into “unity-power-factor-generator”, and therefore extend the active power output capability of the power plant.
