| Abstract: | As an important part of a substation,correct design of DC system directly affects the substation safety and reliability.For the new operation model of unattended 500kV substation, the DC system was with high requirements compared to manned substation.The development of substation DC power technology was introduced,the DC load of substation was analyzed,the configuration schemes for cumulator capacity and charging device capacity were proposed in this paper.An example of DC load typical design and cumulator capacity and the charging device capacity calculation was presented for a 500 kV substation,it will be a reference for the same DC power capacity configuration rehabilitation. |
