摘要
针对未来电动汽车充电站选址分散的特点,建立基于虚拟仪器技术的分布式电动汽车充电站在线监控系统,对充电站的电能质量状况及负荷特性进行长期的监测。将分布式电动汽车充电站在线监控系统从功能上划分为前置机系统、服务器系统及网络通讯系统,分别从软硬件设计、实现方法、系统框架等方面描述三个子系统,探讨不同电能质量参数的测量计算方法,并设计了故障录波模块。实验测试证明,该监控系统测量精度较高,网络传输时无数据丢失。
In this paper, the distributed monitoring system based on virtual instrument technology is proposed to be established for future scattered electric vehicle charging stations. The distributed monitoring system is divided into front-end system, server system and network communication system. Then these three subsystems are described from the aspects of the design of hardware and software, methods of implementation and system framework. The measure- ment and calculation methods of different power quality parameters are explored and the fault recorder is designed. The experiment shows that the designed monitoring system has high measurement accuracy with no data loss in network transmission.
