摘要
以同步旋转坐标系下的静止同步补偿器(STATCOM)模型为基础,通过对传统比例积分(PI)算法的深入研究,引入非线性PI算法,即在原有PI算法上添加过渡过程,并对该过渡过程进行详细设计。该方法克服了传统PI算法的快速性与超调的矛盾,从而缓解了STATCOM启动时的初始冲击,降低设备成本,最后通过仿真和实验验证其有效性。
Based on the static synchronous compensator（STATCOM） mathematical model in the synchronous rotating reference frame, by the research on traditional proportional integral （PI） algorithm, the nonlinear PI algorithm is proposed which include transition process, and the transition process is designed in detail.This method overcomes the contradiction of rapidity and overshoot in traditional PI algorithm, so the initial shock is alleviated and the equipment cost is reduced.Finally, the effectiveness is verified by simulation and experiment.
