摘要
随着电力系统互联规模不断扩大,系统稳定性问题也变得更加突出。同步发电机励磁控制作为提高系统稳定性最有效和最经济的措施,也在逐步发展。全面概括了励磁控制的原理及功能,总结和分析了现阶段研究成果,并从提升电力系统稳定器(PSS)抑制低频振荡的能力、考虑励磁辅助环节对系统阻尼的影响以及多机系统协调控制三个方面提出了励磁控制下一步研究方向。
With the increasing of power system interconnection,maintaining system stability become a prominent problem.Synchronous generator excitation control,as the most effective and economical measure to improve system stability,is highly developed.This paper fully describes the principle and function of excitation control,summarizes and analyzes current research results,and finally proposes future research trend and prospect of excitation control from three aspects:improving the ability of PSS to suppress low-frequency oscillation,analyzing the influence of excitation auxiliary on system damping,and multi-machine system coordinated control.
