摘要
受端系统为弱系统时 ,高压直流系统很容易引起换流站交流母线的电压不稳定现象。评价 3种判别交直流系统电压稳定性方法的优缺点 ,并应用电力系统电磁暂态仿真软件EMTDC对CIGRE高压直流系统模型进行了仿真研究。研究结果表明 。
HVDC system connected to weak AC system is inclined to cause the phenomena voltage instability on the converter bus. The paper evaluates three methods for assessing AC/DC system voltage stability and simulates them on the CIGRE HVDC model by means of EMTDC. The results show that adequate reactive power compensation and DC control method can improve the system voltage stability.
