ABSTRACT This paper presents results of online identification of hydrogenerators, a long-term running robust self-tuning regulator of generator excitation, governor power system stabilizer decoupled in multimachine systems, and an adaptive GPSS designed in frequency domain. 1. It presents a step-by-step zero cancellation method , accuracy weighted recursive least squares and approximate RLS algorithms, inferior limit of sampling time.

针对发电机励磁和调速系统建模与控制，针对多机电力系统的稳定性，本文综述了自适应控制理论及其在电力系统中应用的现状和发展方向后，在辨识、自适应控制结构和鲁棒性提高的措施上进行了研究，取得了水轮机调速系统现场辨识的成功，获得了长期稳定运行的鲁棒励磁自校正控制器、多机解耦的调速侧电力系统稳定器和频域设计的自适应GPSS。
