摘要
直流输电线路保护动作后再启动逻辑的优化改进能够提高电网系统的运行稳定性.通过对葛南超高压直流输电工程的直流线路再启动逻辑过程的分析,指出了线路出现故障时再启动功能存在的不足,并对再启动逻辑模块实施了改进.通过对改进前后的仿真试验波形的比较,验证了再启动逻辑改进措施的有效性,对高压直流线路现场运行具有一定的指导意义.
The optimization and improvement of restart logic after DC line protection can improve the operation stability of power grid system.Based on the analysis of the DC line restart logic process of Genan UHVDC transmission project,this paper points out the deficiency of the restarting function in the case of line fault and improves the restarting logic module.Through the comparison of simulation test waveforms before and after the improvement,the effectiveness of the improved restart logic measures is verified.The research result has certain guidance significance to the field operation.
