摘要
随着智能化变电站以及无人值守变电站的推广建设,针对蓄电池实现有效的远程维护管理已成为目前迫切需要解决的问题。文章研究了一种基于并网逆变技术的蓄电池远程充放电维护管理系统,改变传统的使用电阻箱(假负载)对蓄电池进行核对性放电的维护方式,实现了蓄电池核对性放电的智能化、高效化;弥补了在核对性放电过程中缺乏实时精确的在线监测手段的不足,实现对蓄电池运行工况的实时在线监测,为电力变电站蓄电池的运行维护提供了有力保障。
With the development of smart substation technology and unmanned substation, it has become an urgent task to realize effective remote maintenance management for storage battery. This paper studied a grid-connected inverter based battery charging and discharging remote maintenance management system, changing the traditional battery maintenance mode of using resistance box （false load） to check discharging. The system realized intelligent and efficient check discharging, made tip the lack of accurate real-time online monitoring means of check and discharging process. Thus the real-time online monitoring of battery operation status was archived, which provided a strong guarantee for power substation storage battery operation and maintenance.
