组合电力系统自适应稳定器PSS的设计

Design of an adaptive stabilizer for combinational electric system

介绍一种用于经输电线与无限大母线连接的同步发动机的组合电力系统自适应稳定器的设计方案。与传统的电力系统稳定器不同 ,它包括几个自适应稳定器 ,且这些稳定器同时又并联工作。稳定控制信号由各个单一的电力系统自适应稳定器的加权获得。同时又研究了加权系数的选择方法。最后给出的系统的仿真结果表明该稳定器与以往电力系统稳定器相比具有强的鲁棒性。

This paper reports a novel design of adaptive stabilizer for combinational electric system,connecting the synchronous generator with infinite busvia transmission line. The project is different from that of the convention.It comprises several paralleled adaptive stabilizing devices. The control signalis obtained by weighting the adaptive stabilizer used in each individual system.Method for determining the weighting factors is proposed.Emulation results verify that this adaptive stabilizer is superior in robustness than that of the ordinary design.
