摘　　要：研究在贵州电网近区加装SVC，抑制由黔江小水电诱发的低频振荡模式。通过仿真计算结果表明，带有附加阻尼控制的SVC可有效提高黔江小水电主导的振荡模式阻尼，提升黔江小水电安全出力裕度，提高系统的安全稳定程度，该应用具有较大的推广价值。In this paper, the application of SVC in Guizhou Power Grid is studied to damp the oscillation mode induced by Qianjiang hydro power. The analysis result shows that SVC with supplementary damping control ean effectively increase the damping ratio of the chief oscillation mode, the safety margin of output of Qianjiang hydro power and the stability of the power system. The research result can also be apphed in similar cases.
