摘要
针对单机无穷大系统,采用凸极式发电机(xd′≠xq)模型,建立了包含静态同步补偿器(STATCOM)的系统方程,并利用微分几何线性化方法,实现了凸极式发电机励磁与STATCOM的协调控制,克服了以往的STATCOM模型需要假设STATCOM输出电压矢量在d轴的强约束条件。该设计方法进一步推广了微分几何线性化理论和控制器的应用范围,并提高了STATCOM与励磁协调控制的实用性。仿真结果表明文中所提出的模型和协调控制方法的合理性和有效性。
A system equation for a power system with a static synchronous compensator （STATCOM） is proposed.As an example,a single machine infinite-bus（SMIB） system is studied using a salient-pole generator（xd ′ ≠ xq） model.A differential geometric linearization method is adopted to achieve the coordinated control of generator excitation and the STATCOM.The model of nonlinear system with constraints algebraic equations composed by salient pole generator and STATCOM is established which overcomes the previous strong constraints conditions that the output voltage vector of STATCOM must be set in the d-axis,thus the STATCOM model and control method presented are designed primarily to meet the practical engineering applications.This design method further generalizes the application scope of differential geometry linearization theory and controller. The simulation results demonstrate that the model and the control scheme proposed here are reasonable and effective.
