| 摘 要： | 针对电力系统的强非线性和不确定性,应用非线性控制理论,基于非线性跟踪微分器及PID校正思想,设计了一种用于静止无功补偿器(SVC)与发电机励磁的非线性PID协调控制策略.该控制策略具有不依赖于被控系统知识的特点,对系统工作点和网络结构的变化具有良好的鲁棒性,且结构简单,易于实现.利用Matlab/S-function 仿真表明,SVC与发电机励磁的非线性PID控制策略能有效地提高电力系统暂态稳定性.

| Abstract: | As for the strong nonliterary and uncertainty of power system, a new kind of controller for Static Var Compensator (SVC) cooperating with excitation system of generator based on the theory of nonlinear PID (Proportion Integral Differentiator) control is presented. The controller does not depend on the model of power system, having valuable robustness about working point and the structure of the power, and having simple structure, easy to realize. Simulation results using Matlab/S-Function demonstrate that the proposed controller can improve dynamic stability of power system effectively. |
