摘　　要：介绍了一种用于经输电线与无限大母线连接的同步发电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。同时也研究了加权系数的选择方法。最后给出系统的仿真研究,结果表明该稳定器与以往电力系统稳定器相比具有较强的鲁棒性。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 form that of the convention. It comprises several paralleled adaptive stabilizing devices. The control signalis obtainedby weighting theadaptive stabilizer used in each individual system. Meth- od for determining the weighting factors is proposed. Emulation results verify that this adaptive stabilizer is superior in robustness than that of the ordinary design.
