Power system excitation control based on support vector machine

A new synchronous generator excitation controller is provided in this article. On the basis of the linear multi-variable excitation controller, a composite controller, which ties the output of PID with the output of linear multi-variable excitation controller and the output of support vector machine (SVM) inverse model, was designed based on SVM. Inverse system method is applied to the design of the composite controller for the single-machine infinite system, the design method provided in this article is very simple, simulation demonstrates that excitation controller provided in this article is very effective for the improvement of power system stability and the stability of generator terminal voltage compared with the linear multi-variable excitation controller and traditional PID controller.
