摘要
蓄电池组作为变电站中的备用电源,对变电站乃至整个电力系统的安全运行有着重要意义。从变电站的实际生产角度出发,分析现有蓄电池组运维方式存在的缺陷,提出一种对蓄电池组进行远程在线监测和核对性充放电的维护方案。介绍了该方案的系统构成、可实现功能和工作原理。通过实际应用,证明了该系统可以远程实时监控蓄电池的运行状态、电压、内阻和温度等,并对蓄电池组进行远程核对性放电,提升了变电运维人员的工作效率,增加了变电站直流系统的可靠性。
As the backup power supply in the substation, the battery bank is of great significance to the safe operation of the substation and even the whole power system. From the point of view of the actual production of substation, the defects of the existing operation and maintenance methods of battery banks are analyzed, and a remote on-line monitoring and check charge and discharge maintenance scheme of battery banks is proposed. The system structure, realizable function and working principle of the scheme are introduced. The practical application proves that the system can monitor the running state, voltage, internal resistance and temperature of the battery in real time, and carry out remote checking discharge of the battery. It improves the working efficiency of substation operation and maintenance personnel and increases the reliability of DC system of substation.
