摘　　要：风电场无功电压控制策略、各分系统间通信、单体设备性能等各个环节都将影响场站无功电压控制性能。依据某千万千瓦级风电基地近三年来的实际运行数据及现场检测数据,首先分析了风电场无功电压控制系统现状,系统介绍了目前无功电压控制系统架构及常用控制策略;其次从场站无功电压控制流程入手,阐明了影响场站无功电压控制性能的关键因素;最后形成了提升风电场无功电压控制性能及运行水平的措施,并进行了实例验证。The control strategy of automatic voltage, the communication between systems and the performance of single device affect the performance of the reactive power and voltage control of wind farms. Based on the actual operation data and field testing data of a ten-million-kilowatts wind power base in the past three years, the paper firstly analyzes the status of the wind farm automatic voltage control （AVC） system, and systematically introduces the current AVC system architecture and conventional control strategies; and then it clarifies hhe key factors affecting the wind farm AVC performance from the wind farm AVC process. Finally, some measures are proposed for improving the wind farm AVC performance and operation level, and are verified by case study.
