Abstract

This paper proposes a novel nonlinear feedback control for multi-machine power systems with unknown parameters. There is no need for a state observer and knowledge of the system parameters. The implementation of the control system is therefore more simple. The proposed control algorithm maintains the power angle of each generator within a predetermined restriction for any time and enhances transient stability simultaneously. Simulation results illustrate the effectiveness of the proposed algorithm.

基于坐标变换的多机电力系统非线性反馈控制

针对多机未知参数电力系统，提出了一种新的非线性反馈控制方法。不需要状态观测器和系统参数的知识。因此，控制系统的实现更加简单。该控制算法在任何时间都能使各发电机的功率角保持在预定的限制范围内，同时提高暂态稳定性。仿真结果验证了该算法的有效性。
