摘要
结合电力发展的特点,分析了智能电站的需求,探讨了智能电站建设新形势下励磁技术发展的重点,指出了励磁调节与控制的冗余容错及故障自诊断设计、大区域联网后电力系统低频振荡的抑制、辅助环节控制策略、辅助环节与主环间的协调控制等方面是智能化励磁需要开展的工作,是智能电站建设的主要组成部分。
According to the development of electric power systems,the needs of smart power stations are analyzed and the development priorities of generator excitation technologies are discussed under the new situation of smart power station constructions.It is pointed that designs of redundancy-tolerance and Self-diagnosis systems for generator excitations and controls,suppression of low frequency oscillation in electric power systems after large regional interconnections,control strategies of supplementary links,coordinated controls between supplementary links and main links are required works of intelligent excitation and the key components of intelligent power station construction.
