Problems solved by technology

In actual application, the automatic voltage regulator designed by this method needs to finally determine the PID control parameters through repeated manual debugging according to the model parameters of the synchronous generator. This design process is cumbersome and inefficient, and the obtained PID control parameters can only guarantee The regulation of terminal voltage of synchronous generator meets the performance requirements, but it cannot achieve the goal of optimal regulation performance of terminal voltage

Abstract

The invention discloses a synchronous generator automatic voltage regulator regulation method based on an intelligent optimization algorithm. The method is characterized by carrying out differential flat transformation on a synchronous generator system by selecting the power angle of a generator as flatness output of a synchronous generator system model to enable the system to be converted into a three-order linear system; for the system, an automatic voltage regulator is designed to adjust the terminal voltage of the synchronous generator system by adopting a finite time convergence control method, thereby improving the performance of voltage regulation of the synchronous generator; and on the basis of a harmony search optimization algorithm, the parameters of the automatic voltage regulator are optimized, thereby realizing automation degree of the design of the automatic voltage regulator of the synchronous generator, and preventing the problem of low efficiency since the PID parameters need to be adjusted repeatedly and manually when the automatic voltage regulator is designed through a conventional PID control method.
