| Abstract: | The principle of substation's voltage and reactive power controllers and the conceptions of voltage stability were analyzed. On the base of voltage stability, the VQC-software control of on-load tap-changer was analyzed with disturbance. In virtue of wide area measurement system (WAMS) and wide area network (WAN), an improvement of voltage and reactive power automatic control software based on SCADA can be put forward. |
