This paper proposes a nonlinear coordinated controller for a single machine infinite bus power system. The later consists of a synchronous generator connected to the infinite bus via transmission lines, which are equipped with a static var compensator. The proposed control strategy aims to control simultaneously the excitation system of the synchronous generator and the static var compensator in order to improve transient stability and voltage regulation. The input output linearization theory and pole-assignment technique are employed to design the nonlinear controller. The controller’s performance in single machine infinite bus power system is then examined using simulation studies when the studied power system is subjected to three-phase short circuit with a 100ms duration. The results validate the efficiency of the proposed controller, which is based mainly on the good regulation of the static var compensator voltage with removing the static error after fault elimination.

基于输入输出线性化的电力系统发电机励磁与静止无功补偿器非线性协调控制设计

本文提出了一种单机无限母线电力系统的非线性协调控制器。后者由一个同步发电机组成，该发电机通过传输线连接到无限母线，并配备有静态无功补偿器。所提出的控制策略旨在同时控制同步发电机的励磁系统和静态无功补偿器，以提高暂态稳定性和电压调节。输入输出线性化理论和极点分配技术被用来设计非线性控制器。当所研究的电力系统受到持续时间为 100 毫秒的三相短路时，控制器在单机无限母线电力系统中的性能然后使用仿真研究来检查。结果验证了所提出的控制器的效率，
