摘　　要：简单介绍了基于坐标变换和反馈控制理论的一种反馈线性化方法——逆系统方法。运用逆系统方法将含可控串联补偿电容器 (TCSC)的非线性电力系统线性化 ,并且对该线性化的系统运用具有二次型性能指标的线性最优控制方法设计了 TCSC的稳定控制器。将其与用微分几何法和用直接大范围线性化法设计的控制器进行了比较 ,结果表明它们具有相同的控制效果 ,即均能提高电力系统的暂态稳定性。A feedback linearization method based on coordinate transformation and feedback control theory-inverse system method is briefly presented. Linearizing a nonlinear power system with TCSC and applying the linear optimal control technique which possesses the quadratics index to the linearlized system, a TCSC stability controller is designed. Comparing this controller with those developed by differential geometry method or direct linearization method over wide range, the result showes that all the controllers possess same control effect, i.e., they can improve the transient stability of power system.
