摘要
研究设计了一种太阳能光伏电源系统,并成功应用于户外电力设备在线监测系统中。根据设备功耗需要和安装地点的气候情况,确定了光伏阵列和蓄电池的容量;研究了不同光照和温度条件下,光伏阵列的最大功率点跟踪(Maxmum Power Point Tracking,简称MPPT)算法,使光伏阵列始终工作在最大功率输出状态,保证了蓄电池的充电效率;研究设计了多电池组协调控制与充-放电优化管理策略,有效延长了蓄电池的使用寿命。设计开发的太阳能光伏电源系统在架空输电线路状态监测系统中得到了成功应用。现场运行结果表明,该系统运行高效、稳定,完全满足工程应用需求。
A solar photovohaic （PV） power supply system with multi-buttery was developed and successfully applied to outdoor on-line monitoring devices of electric power equipment.First, the capacity of PV array and battery was selected according to the need of the power consumption of devices and the weather condition the devices was placed.Then the maximum power point tracking （MPPT） was studied in different illumination and temperature to ensure the maximum output of PV array and the charge efficiency.Finally, the battery grouping and the charge and discharge strategy effectively extended the life of battery pack.The solar PV power supply system is successfully applied to monitoring system of overhead electric transmission line.Operational results show this PV power supply system has the high stability and efficiency, and absolutely meet the needs of project application.
