摘要
利用国家863电池试验室的设备,对变电站淘汰的一组电池做详细测试,研究实际使用中的电池的失效模式,掌握电池的外部特性,如电流、电压、温度等与失效模式的关系,构造电池的数学模型,对单体电池剩余容量及单只电池的健康度(SOH)进行预测,形成一套有效的预测算法,及早发现问题,及早处理,避免事故发生;采用单体电池主动均衡达到电池均衡的目的,提高电池的安全可靠性和使用寿命;采用IEC61850作为通讯协议,为实现智能变电站奠定基础;最终形成一套集电池运行参数在线监测及存储、电池组主动均衡、电池容量和健康度预测、IEC61850通讯的在线智能电池管理系统,真正实现蓄电池组在线维护和状态检修,适应智能变电站对电池管理的要求。
The use of state 863 battery testing equipment, the substation out a set of batteries do detailed test, study the failure mode of the battery in the actual use, to master the external characteristic of battery, such as current, voltage, temperature and failure mode of the relationship, a mathematical model of the battery, on the residual capacity of battery and single monomer battery for predicting the degree of health(SOH), forming a set of effective prediction algorithm, early detection problem, early treatment, avoid the accident; Using monomer battery active balance to achieve the purpose of battery balance, improve the safety and reliability and service life of the battery; Using IEC61850 as communication protocol, lay a foundation for the realization of the intelligent substation; Eventually formed a set of on-line monitoring and storage battery operation parameters, the active balance of battery, battery capacity and health prediction, IEC61850 communication online intelligent battery management system, realize battery online maintenance and maintenance, to meet the requirements of intelligent substation of battery management.
