电动汽车充电站综合监控系统设计

摘要

首先介绍当前电动汽车获取电能的三种方式及其优缺点,充电站的系统概况和数据流向.电动汽车充电桩的大规模接入会对配电网产生负面影响,监控系统对于保障充电过程安全、提高充电站运营管理自动化水平、改善电网电能质量发挥着至关重要的作用.在充电站监控系统设计中将系统细分为充电监控、换电监控、配电监控、电能质量监控、安全防护监控,并基于LabVIEW平台完成监控软件设计开发,并对系统的功能可靠性进行验证.%At the beginning,this paper introduces three prevailing methods for EV power supply and their merits and demerits,system overview and data flow of charging stations.Large-scale access of charging piles will produce negative effects on the distribution network.The monitoring system plays a crucial part in ensuring charging process safety,raising automation level of charging station' s operational management and improving grid power quality.In the design of the station monitoring system,it is segmented into charging monitoring,battery replacement monitoring,power distribution monitoring,power quality monitoring and safety protection monitoring.Design of monitoring software is completed on the basis of LabVIEW platform,and functional reliability of the system is verified.
