摘　　要：基于Power World软件研究电力系统中无功源的资源价值问题.用PV曲线法、无功备用法、等效无功补偿法等3种方法对无功源的无功资源价值进行仿真分析.仿真结果表明,无功资源价值的大小取决于无功源的地理位置和网络结构等因素,而无功源与负荷中心之间的距离是最重要的因素.在此基础上,对3种方法的优劣进行了深入的比较分析,提出了改进的等效无功补偿法,仿真分析验证了改进等效无功补偿法的合理性和有效性.Reactive power evaluation is studied using Power World software. Three methods, including the PV-curve method, the reactive reserve method and the ERC method, have been used to simulate and measure the value of reactive power. The result indicates that the value of reactive power is determined by resource location, network configuration and other factors. The distance between the reactive power resource and the load center is the most important factor. Based on this, an improved equivalent reactive power compensation method is advanced, which is proved to be reasonable and effective by simulation analysis.
