静止同步发生器的控制器参数优化

Parameter Optimization of STATCOM Controller

针对新型静止同步发生器(STATCOM),建立欧拉-拉格朗日方程模型。对其PBC控制器在参数上进行优化,该优化设计没有对系统模型进行简化,因此没有破坏其内部结构。对STATCOM的无源性控制器与优化后的控制器进行比较,仿真结果表明该优化是正确的,能够更有效的使电网保持稳定,减少震荡,节约成本。

According to the novel nonlinear mathematical model of static synchronous compensator （STATCOM） established on the Eu- ler-Lagrange system, an optimized measure of PBC （passivity-based control） method has been presented in this paper. Compare to the routine PBC controller, the optimized one can be more effective on keeping the stability of power system and better to satisfy the requirement of engineering practice.
