摘要
在探讨可控硅换流阀内暂态过电压分布特点的基础上建立了阀体的嵌套等值电路模型。通过对±500 kV三峡-常州直流输电系统的可控硅换流阀的计算,分析了阀参数及分布参数对冲击电压分布的影响,并提出了改善电压分布的措施。
An equivalent circuit model of a thyristor valve is established, through detailed study on characteristics of its transient overvoltage distributions. The influence of valve parameters and the value of stray capacitance on lightning impulse voltage distribution is analyzed based on calculation of the thyristor valve used for the Three Gorges -Changzhou ±500 kV DC transmission line. Optimal measures for improvement of transient voltage distribution are recommended.
