| description | The invention provides a novel substation direct-current system and a reliable power supply method; the novel substation direct-current system comprises more than one control cabinet, each control cabinet is internally provided with a direct current subsystem, and the direct current subsystem comprises a hybrid energy storage system and a direct current load; the hybrid energy storage system comprises a super capacitor and a lithium battery. The super capacitor supplies power to short-time high-power loads including opening and closing, and the lithium battery supplies power to other stable direct-current loads. The power supply reliability of the substation direct-current system can be effectively improved, the service life of the storage battery is prolonged, the substation modularization level is improved, and the occupied area of the substation is further saved.
本发明提供了一种新型变电站直流系统及可靠供电方法，包括一个以上的控制柜，每个控制柜中设置有直流子系统，该直流子系统包括混合储能系统以及直流负荷；所述混合储能系统包括超级电容器以及锂电池；由超级电容器为包括分合闸在内的短时高功率的负荷供电，由锂电池为其余平稳的直流负荷供电。本发明能够有效提升 |
