Nonlinear Interference Suppression and Stability Control Methods of Power System

Abstract

Nonlinear control system is a hot research field nowadays. At the same time, how to eliminate or reduce the influence of external interference by control system has always been a concern of scholars. The purpose of this paper is to study the practicability of nonlinear interference suppression and stability control methods for power systems. In this paper, a control method is proposed, and based on this research, the experimental results of nonlinear interference suppression and stability control methods for power systems are analyzed. The experimental results in this paper show that the control effect of the generator with the additional controller of the nonlinear disturbance suppression and stability control method of the power system is better than that of the generator with the DC controller under different load models and different operation modes, and it can return to stability faster, while the traditional controller cannot guarantee the stability of the system under large disturbance. In a word, the nonlinear interference suppression and stability control method of power system proposed in this paper has universal practicability.
