摘要
以电磁暂态程序EMTP为计算工具,对直流输电线路的全电压起动过电压进行了详细研究.首先采用“葛洲坝──上海”直流输电线路参数,建立了一个较完整的直流输电线路全电压起动过电压计算模型,然后分别就系统接有避雷器保护和没有避雷器保护两种情况,对全电压起动过电压进行了分析计算,并仔细讨论了各种有关因素对该种过电压的影响,获得了一些有实用价值的结论。
In this paper, the overvoltage during full-voltage starting on DC transmission lines has been investigated in detail by EMTP. Firstly, a EMTP model of full-voltage starting in HVDC transmission line has been established with the parameters of 'Gezhouba-Shanghai' DCtransmission line. Then, the ovcrvoltage was calculated in both cases dependent on Whether the arresters were used for protection. Moreover, the influence of various factors on the overvoltage was discussed, and some valuable results were obtained.
