变电站是输变电系统中重要的组成部分，变电站的运行稳定性、工作效率等直接关系到整个供电网络的运行质量及效率，从而对国计民生产生各行各业产生着重大影响，而目前变电站的电源一般包括站用直流电源、站用交流电源、UPS电源、站用通讯电源四部分主要供电系统及一个辅助的线路切换供电系统，为了提升变电站运行的稳定性，这几个供电系统通常被设计为独立的工作系统，各系统之间不存在任何关联，但这种设计也导致了各系统之间缺乏有效统一的监管及维护，从而对导致变电站的运行参数、运行状态、故障隐患等缺少及时的信息反馈，从而一方面导致了对变电站监管工作混乱，另一方面也降低了变电站运行的自动化程度，无法满足供电系统发展的需要。 The substation is an important part of the power transmission and transformation system. The operation stability and work efficiency of the substation are directly related to the operation quality and efficiency of the entire power supply network, which has a major impact on the national economy and people's livelihood. Generally, it includes four main power supply systems including station DC power supply, station AC power supply, UPS power supply, station communication power supply and an auxiliary line switching power supply system. In order to improve the stability of substation operation, these power supply systems are usually designed as Independent working system, there is no relationship between each system, but this design also leads to the lack of effective and unified supervision and maintenance among the various systems, resulting in the lack of timely information on the operating parameters, operating status, and hidden troubles of the substation. Information feedback, on the one hand, led to confusion in the supervision of substations, on the other hand, it also reduced the degree of automation of substation operation, which could not meet the needs of power supply system development.
