摘要
本文提出了一种新的双环自适应最优励磁控制器(DAOEC).其中一环采用ΔVt作为第一输入(AEC1),另一环采用Δω作为第二输入(AEC2).由于AEC1和AEC2均具有实时参数辩识环节,因而可以很好地相互协调,同时使ΔVt和Δω具有优良的性能.通过对单机无穷大系统和多机系统(多模振荡系统)的仿真计算,显示了DAOEC比AVR+PSS更优越的性能.论文中还针对DAOEC中几个问题进行了探讨.
A new double-loop adaptive optimal excitation controller (DAOEC) was propssed in this paper.One of the loops (AECl) adopted ΔV1 as its input signal, and another loop (AEC2) took Δω as its input signal. As RLS identifiers are included in both AEC1 and AEC2, so AEC1and AEC2 can coordinate very well, also the performances of both ΔVt and Δω can be guaranteed. Simulation results carried out on one single machine infinite bus system and one multimachine system (multimodal oscillation power system)show that DAOEC possesses much better performances than AVR+PSS. Several questions have also been discusses in this paper.
