摘　　要：在新型电力系统含有大量分布式电源的背景下,为提高负荷电压的稳定性,找寻合理的无功补偿装置配置方式具有重要意义。针对无功补偿装置类型选择的问题,提出在配电网中采用SVC与STATCOM联合补偿的方法;针对无功补偿接入点的选取问题,提出采用改进灵敏度算法选择最优补偿点。通过MATLAB的仿真研究结果显示,某实际配电网应用该方法后,无源配电网负荷电压提高3.37%~12.99%,有源配电网负荷电压提高5.35%~38.73%。结果表明,联合补偿法与改进灵敏度算法同时适用于无源与有源配电网,为无功补偿装置配置方式研究提供了借鉴思路。Under the background of the new power system containing a large number of distributed power sources it is of great significance to find a reasonable configuration of reactive power compensation device in order to improve the stability of load voltage.Aiming at the problem of reactive power compensation device type selection a method of joint compensation of SVC and STATCOM in distribution network is proposed.Aiming at the selection of reactive power compensation access point an improved sensitivity algorithm is proposed to select the optimal compensation point.The simulation results of MATLAB show that the load voltage of passive network increases by 3.37%~12.99%and the load voltage of active network increases by 5.35%~38.73%after the application of this method in an actual distribution network.The results show that the combined compensation method and the improved sensitivity algorithm are suitable for both passive and active distribution networks which provides a reference for the research of reactive power compensation device configuration.
