摘要
随着电力系统和通讯系统容量的日益庞大,蓄电池组作为直流后备电源的重要组成部分,对其稳定性和可靠性提出了更高的要求,对这些无人职守站和机房后备直流电源进行日常的监测和维护是必不可少的,重要的变电站现在都配置了在线监测装置来实时的监测蓄电池组的状态。内阻是反映电池性能的重要参数,因此对蓄电池内阻模型、阻抗分析以及蓄电池在线监测的内阻测量方法和原理进行了探讨,为进一步研究判断蓄电池的性能提供了依据,对蓄电池在线监测的未来趋势进行了展望和预测。
With the increasing capacity of modern power systems and communications systems,as an important part of DC battery back-up power supply,the higher reliability and stability of battery is required.For these stations of self-service watch and engine rooms of standby DC power,the routine monitoring and maintenance for battery is necessary.At some important substations,battery online-monitoring device is configured for real-time monitoring battery status.The battery＇s internal resistance is an important electrical parameter reflecting the battery performance.The internal resistance model of battery,impedance analysis,the measurement methods and the theory of VRLA battery＇s internal resistance was described,which provided a basis for further study to judge the performance of batteries.Finally,the future trends of battery online-monitoring were prospected and predicted.
