考虑系统非线性的SVC控制器设计

A DESIGN OF SVC CONTROLLER UNDER THE CONSIDERATION OF NON-LINEARITY OF POWER SYSTEMS

考虑系统的非线性，研究了静止无功补偿装置（ＳＶＣ）控制器的设计。应用直接反馈线性化方法设计了ＳＶＣ非线性控制器，解决了电力系统强非线性给设计带来的困难。在此基础上，针对单机无穷大系统进行了计算机数字仿真。分析和仿真结果表明：ＳＶＣ的非线性控制方式与ＳＶＣ的常规控制方式相比，可以有效地改善电力系统的静态稳定性及暂态稳定性。

A design of static var compensator (SVC) under the consideration of non-linearity of power system is studied. The direct feed-back is employed for linearization in the design, and difficulties in design due to sharp non-linearity of power systems are overcome and bringing about a basis for designing digital simulation on a single unit infinite bus system, resulting in effective improvement of power system static/transient stability which is proved by analysis and simulation.
