基于Matlab GUI的PSS参数优化软件的设计

Designing a Software for PSS Parameter Optimization Based on Matlab GUI

为有效提高现场工作人员的工作效率,以PSS参数优化为理论基础,依据实测的励磁系统无补偿相频特性,利用遗传算法进行参数优化。通过对Matlab中图形用户界面控件进行布局设计和回调函数程序的编写,设计了基于图形用户界面(GUI)的PSS参数优化软件,并结合现场实际数据,进一步提高了参数优化的准确性。仿真结果表明,PSS参数优化软件可以快速、便捷地设计出最优的PSS参数,整定后的PSS比原始参数对应的PSS更能有效保持系统稳定性。

The PSS parameters are obtained by genetic algorithm according to the uncompensated phase frequency characteristics of measured generating set.At the same time,using the layout design through control of the Matlab graphical user interface(GUI)and callback function program,an GUI based software for PSS parameters optimization is produced.This software can improve the work efficiency of field staff and further improve the precision of optimized parameters.Simulation results show that this software can design the optimal PSS parameters quickly and easily,and the PSS so designed are significantly better than the original PSS parameters.
