Abstract

A typical 1 MVA charging station for electric cars connected to the overhead distribution system through underground medium voltage cables is modeled in the ATP-EMTP environment. Fast-front overvoltages impinging on the AC and DC sides of charging station equipment due to a wide range of lightning strikes to the incoming overhead medium voltage line are computed; positive and negative recorded lightning stroke currents are also considered. The risk of failure is evaluated by considering the rated impulse withstand voltage level of the charging station equipment by assessing the effects of lightning polarity, peak current, and soil resistivity. A protection scheme involving the installation of surge protective devices is investigated to diminish the risk of failure of equipment and interconnected charging cars. The energy absorption capability of surge protective devices against remote lightning strikes is assessed and the necessity of integrating surge protective devices to electric vehicles offering dedicated surge protection is discussed.

充电站对进站中压架空线路雷击冲击过电压的浪涌保护

在ATP-EMTP环境下，对典型的1 MVA电动汽车充电站进行建模，该充电站通过地下中压电缆与架空配电系统连接。计算了进站架空中压线路大范围雷击对充电站设备交直流侧冲击的快前过电压；还考虑了记录的正、负雷击电流。通过评估雷电极性、峰值电流和土壤电阻率的影响，考虑充电站设备的额定抗冲击电压水平来评估故障风险。研究了一种涉及安装电涌保护装置的保护方案，以降低设备和互联充电车的故障风险。评估了电涌保护装置对远程雷击的能量吸收能力，讨论了将电涌保护装置集成到提供专用电涌保护的电动汽车上的必要性。
