摘　　要：介绍变电站电压及无功调节(VQC)的原理,电压稳定的概念,再从电压稳定性角度出发,分析电力系统扰动情形下VQC对OLTC的控制,之后结合广域测量系统(W AM S)和广域网对基于计算机监控系统的VQC提出改进方案。In this paper,the principle of substation＇s voltage and reactive power controller and the conception of voltage stability are introduced . On the base of voltage stability, the VQC-software control of on-load tapchanger is analyzed with disturbance. And then in virtue of Wide Area Measurement System （WAMS） and Wide Area Network（WAN）,an improvement is put forth of voltage and reactive power automatic control software based on SCADA .
