摘　　要：小水电发电技术对于未来电力系统来说是重要发展趋势之一,是充分开发和利用可再生能源的理想方式,对未来大电网可以起到提供有力补充和有效支撑的作用。以含小水电的某10kV线路为例,通过潮流计算,分析了丰水期线路电压偏高的原因,提出在线路上安装动态无功补偿装置,保证设备靠近变电站的一侧电压保持现有状态,同时解决了丰水期线路电压偏高的问题,提高了线路上用户的电压质量,保证了电网的安全运行。Small hydropower generation technology,by fully developing and using renewable energy,is an ideal way to provide a powerful supplement and effective support for future large grid system.Taking a small hydropower of 10 kv line as an example and based on power flow calculation,this article analyzes the reasons for the high line voltage raised in the wet period.It is suggested that installing dynamic reactive power compensation device on one point of the line can ensure that the voltage of the equipment close to the side of substation can maintain the ex-isting status,and can settle the problem of high voltage lines in the wet period and improve the users’voltage quality and the safe operation of the grid.
