摘　　要：电力系统中的无功分布情况对系统本身的稳定起到重要作用,采用在线自动调节系统电压无功的自动电压控制(AVC)系统对保证电能质量、提升输电效率、降低网损有益。通过探讨AVC作用原理,重点对在AVC系统下发遥控命令后,被遥控的测控装置不能正确响应的偶发性情况进行分析和探讨,同时给出相应的解决措施。The distribution of reactive power in the power system plays an important role in the stability of the system.The AVC system with online automatic regulation of system voltage and reactive power is beneficial to ensure power quality,improve transmission efficiency and reduce network loss.By exploring the working principle of AVC,the situation that the remote control device cannot respond correctly after the remote control command is issued by AVC system is analyzed and discussed,and the corresponding solutions are also given.
