基于Backstepping方法的同步电机励磁优化设计

Optimization Design of Excitation in Synchronous Electric-Machine Based on Backstepping Approach

电力系统设备中,常规的优化方法往往在系统稳定性上考虑不足,从而造成了系统运行稳定性欠佳的问题.针对这一问题,利用Backstepping优化方法将同步电机励磁系统分为几个子系统进行分析设计,并利用理论结果进行了仿真实验.实验证明,该方法较常规优化方法有较强的鲁棒性.对同步电机励磁调节的响应时间比常规方法短,且进入稳态时的振荡次数少,保证了系统的稳定性.

In electric power system equipments, the system stability and robust have not been taken into account in the common optimization approaches. Therefore, the stability and robust system was not good. The excitation of synchronous electric-machine was analyzed and designed by dividing it into sev- eral subsystems, and using Backstepping optimization approach. The simulated result shows that the characteristic of system is much better than the common optimization approaches.
