摘要
本文对由晶闸管控制电抗器(TCR)型装置与一个固定电容器组(FC)型装置组成的静止无功补偿系统(SVC)建立了一个三阶非线性动态模型。并对该模型应用直接反馈线性化理论(DEF)提出了一种新的SVC的非线性控制策略。用MATLAB软件对输电线路上装设SVC的三母线系统进行仿真。
This paper discusses a nonlinear design for TCR-FC Static Var Compensator (SVC) to improve power system voltage stability.A third order nonlinear dynamical model for the SVC system is the developed.Direct feedback linearization (DEF) technique is employed to design a nonlinear control strategy.The effectiveness of the control strategy on voltage stability enhance is studied on a three-bus power system through time simulation.The result shows that the proposed control strategy is effective in voltage stability enhancement.
