摘　　要：变电站直流电源系统的作用是在站用交流电源失去后,能够持续、稳定、可靠地为保护及合闸机构提供工作电源,确保能够将故障回路从电网系统中脱离出来,避免变电站全站停电事故的发生。然而,由于维护手段落后、工作人员承载力不足、缺乏完善的监控维护手段,导致变电站直流电源系统运行存在潜在的安全隐患。为解决上述问题,构建直流电源运维管理系统,并对其进行验证。结果表明该系统能够实现远程设备状态监控及告警功能,提高运检效率,降低变电站事故风险。The function of substation DC power supply system is to provide working power for protection and closing mechanism continuously,stably and reliably after the loss of station AC power supply,so as to ensure that the fault circuit can be separated from the grid system and avoid the occurrence of substation power failure.However,due to the backward maintenance means,insufficient carrying capacity of staff and the lack of more perfect monitoring and maintenance means,the operation of DC power supply system in substation has potential safety hazards.In order to solve the above problems,this paper proposes a DC power operation management system and verifies it.The results show that the system can realize remote equipment status monitoring and alarm functions,greatly improve the efficiency of operation and inspection,and reduce the risk of substation accidents.
