摘要
本文提出一种带可变遗忘因子的自校正控制算法,用于设计多机系统中同步发电机的励磁自适应控制器。并以一个两机对无穷大系统为例进行数字计算机仿真分析,结果表明,与常规控制相比,励磁自适应控制能大大提高系统的稳定性,有效地改善系统的动态品质,且取就地信息即能实现控制,有希望成为大规模复杂电力系统的控制策略之一。
This paper presents a self-tuning control algorithm with varia- ble forgetting factors.And this method is used to design a self-tuning excitation controller of synchronoous generators working in a multimachi- ne power system.Computer simulation results based on the model of two machine power system of infinite capacity show that the controller could improve the dynamic stability of power systems markedly,using local sig- nals only.It could be expected that this algorithm can be one of the control strategies for large scale power system.
