| 摘 要： | 介绍了交直流电力系统关联测量分散励磁控制的建模方法和控制规律的求取, 所得控制规律既可以分散实现,又能保证全局稳定且性能最优.通过一个典型交直流电力系统(EPRI-36系统)的小干扰稳定计算和暂态仿真表明,关联测量分散励磁控制下的闭环系统在功角稳定性、电压调节精度以及小干扰稳定性方面均优于常规励磁附加PSS.从特征值比较看,关联测量分散励磁控制下的小干扰稳定性可以接近全状态量反馈控制时的性能.

| Abstract: | Based on the theory of associated and decentralized control,this paper introduces the modeling method of AC/DC power system and control law deriving,which can be realized dispersedly and guarantee the stability of the system with optimal performance.Through small signal stability analysis and transient stability simulation in a typical HVDC system(EPRI-36),the results show that some characters of closed-loop system on the basis of associated feedback control,such as angle stability,voltage accuracy and small signal stability,are better than those of AVR+PSS.Meanwhile,small signal stability of the system with associated feedback control is similar to that with all state variable feedback control. |
