摘要
介绍了典型的变电站站用电直流系统接线方案、其特殊运行方式及所带负荷,并重点分析了在一段直流母线失电条件下,系统出现故障情况时,直流负荷的不同分配方案下所产生的不同后果,最后提出了一些和传统方案不同的见解,进一步提高了直流系统的稳定性和可靠性。
The connection scheme, special operation way and load of a representative DC system in 500 kV substation are introduced in this paper. And the different results caused by its different load distribution are detailed when fault occured on both DC system and the grid. This paper puts forward some advice on improving the DC system reliability and stability different from traditional design mode.
