摘要
直流蓄电池系统正常运行时处于浮充备用状态,发生交流电失电或其他事故时,蓄电池作为负荷的唯一能源供给者,要求能及时提供直流电源。目前,直流系统自带的集成监测系统只能监测常规运行参数,蓄电池本身健康状态依靠每年一次的核对性充放电检测,中间存在空窗期。因此,研制充分整合目前直流系统监控常规参数的装置,引入自跟踪自适应的多维变量分析模型算法,为延长蓄电池的可用时长和使用寿命提供可靠依据,保证蓄电池在关键时刻能及时供电,减少全所失电的危险,提升变电站设备运维水平和安全管理水平。
When the DC battery system is in normal operation,it is in the standby state of floating charge.In case of AC power loss or other accidents,the battery,as the only energy supplier of load,is required to supply DC power in time.At present,the integrated monitoring system of DC system can only monitor the normal operation parameters.The health status of the battery depends on the annual checking charge and discharge detection,and there is an empty window period.The device developed in this paper fully integrates the conventional parameters monitored by the current DC system,and introduces the self tracking adaptive multidimensional variable analysis model algorithm,so as to provide the available time and use of the battery the service life provides reliable basis to ensure that the battery can supply power in time at critical time,reduce the risk of power loss in the whole substation,and improve the operation and maintenance level and safety management level of substation equipment.
