多机电力系统中改善动态稳定性的静止无功补偿器装点选择

Selection of Location for Static Var System in Multimachine Power System for Stability Improvement

本文以系统的机电振荡模对静补环节灵敏度为静补选点判据,推导了一套多机电力系统中改善动态稳定性的静补装点选择模型。对一个三机系统的反复计算,分析表明了文中所给选点方法及选点模型的有效性。

The paper presents a novel approach for the identification of the optimum sites of static Var System (SVS) for improving the dynamic stability of multimachine power sytems. The proposed method makes use of the sensitivities of swing modes with respect to transfer functions of SVS as the criterion of the SVS's placements. The repeated computations and analyses of a three machine system illustrate the dfficiency of the preposed method.
