摘　　要：特高压、远距离、大容量电网的建设,对受端电网电压稳定提出了更高的要求,传统固定式补偿设备逐步难以适应电网发展。为此,以河南实际电网为例,重点针对交流特高压及其近区500 kV电网,将时域仿真法、V-Q曲线法及灵敏度分析法相结合,综合分析特高压交直流混联大型受端电网的动态无功配置方案,为大型受端电网动态无功配置研究提供了一种实用的方法。With the constructions of long-distance and large-capacity Ultra High Voltage （UHV） power grids, the receiving-end grid raises an increased standard for voltage stability, Conventional stationary type compensation device is difficult to adapt the requirements of the grid development. Taking the UHV AC grid and Henan 500 kV power grid as an example, the dynamic VAR configuration of the large receiving-end grid in UHV AC and DC interconneetion is analyzed by a comprehensive method, which combined with time-domain simulation, V-Q curve and sensitivity analysis. The proposed method provides comprehensive guidance for the configuration of dynamic reactive device.
