摘要

电压暂降是配电系统中常见的电能质量问题。导致ASD、PLC、电动汽车充电站等敏感设备出现故障。在电动汽车充电的情况下,电压暂降影响了向被充电车辆提交充电的过程。本文利用MATLAB/SIMULINK分析了电压暂降对并网直流母线电动汽车充电站的影响。仿真结果显示了直流电压、充电电流波动、电池电压和干扰对电池荷电状态的影响。本文简要讨论了电动汽车充电中不同的电压暂降缓解技术。

Effects of Voltage Sag on Grid fed Electric Vehicle Charging Station
Voltage sag is the frequently occurring power quality problem in the distribution system. It causes mal-functioning of sensitive equipment like ASD, PLC, and electric vehicle (EV) charging station. In the case of EV charging, voltage sag affects the process of charge submission to the vehicle being charged. In this work, MATLAB/SIMULINK is used to analyse the effects of voltage sag on grid fed DC-bus EV charging station. The simulation results present the effect of DC-link voltage, fluctuations in charging current, battery voltage and disturbance in SOC of battery. Different voltage sag mitigation techniques for EV charging are briefly discussed in this paper.
