摘要
变电站蓄电池组作为变电站发生故障时的最后一道可靠堡垒,其不仅为整站保护、测控装置和事故照明提供可靠的直流电源,而且还为事故状态下倒闸操作提供可靠的操作电源。对蓄电池组进行实时可靠的在线监测对整个变电站甚至电网运行来讲意义重大。本文通过对原先的蓄电池充放电周期的研究和实验,针对蓄电池组现存的不能实时监测的问题,提出了改进型的蓄电池自监测工作模式,从根本上保证了蓄电池组的实时监测和控制。
As the last reliable fortress in the substation, the substation battery not only provides reliable DC power supply for the whole station protection, measurement and control devices and accident lighting, but also provides reliable operation power for the switching operation in the accident state. Real-time and reliable on-line monitoring of the battery pack is of great significance to the entire substation and even the grid operation. In this paper, the original battery charge-discharge cycle of research and experiments for the existing battery can not be real-time monitoring problems, put forward an improved battery self-monitoring mode of operation, fundamentally guaranteed real-time battery monitoring and control.
