摘要
本文首次推导出了单机——无穷大系统中SVC的状态方程,在此基础上设计了SVC的最优控制系统。数字仿真表明,该最优控制系统在提高电能质量及改善系统动态特性等方面均优于其它控制形式。
The writers present for the first time a state equation of static var compensators in single machine operating through an external impedance against an infinite bus. Based on this, an optimal control system of static var compensators, better than other control systems, is designed. Improvements on voltage level and system dynamical characteristics are showed in digital simulation with the system nonlinear model.
