THE NONLINEAR CONTROL OF SVC AND EXCITATION OF GENERATORS IN POWER SYSTEMS WITH DYNAMIC LOADS

基于微分代数控制系统的反馈线性化方法,进一步研究了具有非线性负荷的电力系统中静止无功补偿器(Static var compensator,SVC)和发电机三阶模型的励磁控制,表明具有非线性负荷和SVC装置的NDAS(3)仍可以通过状态反馈精确线性化,从而得到具有代数方程的Brunovsky标准型。提出了具有非线性负荷的电力系统SVC与发电机励磁控制的完全精确线性化设计。该控制方法可以同时满足发电机功角稳定和SVC节点处电压。仿真结果表明该方法具有很好的效果和优越性。

In this paper, based on the feedback linearized technique and control method of differential and algebraic systems, the exact linearization design is presented for static vat compensator (SVC) and generator excitation control in power systems with nonlinear dynamic loads.The two goals of power angle stability of generator and voltage stability of SVC nodes are satisfied simultaneously by this control method. The simulation results are indicated that this control method have good effect and superiority.
