500 kV昭关变电站通信电源系统不停电改造

Reconstruction Without Power Cut of Communication Power Supply System in 500 kV Zhaoguan Electricity Substation

通信电源是电力通信系统的重要组成环节,通信电源系统的安全可靠性是保障电力通信网络安全稳定运行的基础。以安徽区域500 kV昭关变电站为对象,分析了昭关变电站通信电源系统存在的安全隐患,并结合站点通信设备的实际运行情况和后期新增设备电源扩容计划,通过对电源系统容量配置计算验证,制定了总体改造方案,重点提出了对应的负载不停电割接实施方案,保证了电源系统平滑过渡。昭关变电站通信电源系统改造成功验证了变电站通信设备不停电割接方案的可行性,对安徽区域其他站点开展相关工作具有重要的参考价值。

Communication power supply is an important part of power communication system. The security and reliability of communication power supply system is the basis of ensuring the safe and stable operation of power communication network. Taking the 500 kV Zhaoguan substation in Anhui as the object of study,this paper analyses the potential safety hazards existing in the communication power supply system of Zhaoguan substation and combines with the actual operation of the substation communication equipment and the power expansion plan of the new equipment in the later period,through the calculation and verification of the power supply system capacity configuration,formulates the overall reconstruction scheme,and puts emphasis on the corresponding load not. The implementation scheme of power cut ensures smooth transition of power supply system. The successful transformation of communication power supply system in Zhaoguan substation has verified the feasibility of non-stop cutting scheme of communication equipment in substation,and has important reference value for other stations in Anhui region to carry out related work.
