Abstract:

In this paper, the networking scheme of the static var genertor (SVG) equipment and the capacitor joining in the automatic voltage control (AVC) system is introduced. By setting the AVC substation, the system enhances security and stability. Then the control strategy of SVG joining in the AVC system is studied. According to the abnormal defect of SVG response to AVC instructions in substations, the improved measures of the control strategy are put forward. The improved control strategy is applied in the substation and continues to be observed. The actual voltage adjustment approves the effectiveness of control strategy improvement.

Key words: SVG, AVC substation, instruction exception, control strategy
