摘　　要：自动电压无功控制系统AVC是保证电网安全经济运行的重要措施,其投运率和合格率反映电厂子站AVC在电网中的运行质量。本文介绍了华北网调某直调电厂1000 kV系统自动无功电压控制AVC系统实际运行情况,分析其机组AVC投运后合格率偏低的原因,并提出对应解决方案,减少因AVC合格率不符合要求而导致的电量考核。Automatic voltage control system(AVC)is an important measure to ensure the safe and economic operation of power grid.Its operation rate and qualification rate reflect the operation quality of AVC in power plant substation.This paper introduces the actual operation of the reactive power automatic control AVC system of a 1000 kV direct-dispatching power plant in North China Power Grid,analyses the reasons for the low qualification rate of the AVC system after its commissioning,and puts forward corresponding solutions.Reduce the power consumption assessment caused by the failure of AVC qualification rate to meet the requirements.
