Abstract

The introduction of electric vehicles in currently urban transportation system becomes tendency and attractive alternation to traditional fuel cars. Electric vehicles include certain different types and are powered through electric vehicle chargers which are elements in an infrastructure that supplies electric energy for the recharging of the plug-in electric vehicles. There has been much more concern expressed over the power quality issues caused by electric vehicle chargers on low-voltage distribution systems. It is necessary to know the influence of the electric vehicle chargers impact to power grid before electric vehicles operating in scale. In this paper a field measurement is carried out on a low-voltage distribution system with 4 alternating current electric vehicle conductive chargers, that are specified by SAE 1772 standard, and a part of operated nonlinear loads. Some measured results of voltage/current trend, harmonics/interharmonics, flicker, and power quality events are discussed.

智能电动汽车充电基础设施低压配电系统电能质量测量

在当前城市交通系统中引入电动汽车已成为替代传统燃油汽车的趋势和吸引力。电动汽车包括某些不同的类型，并通过电动汽车充电器供电，电动汽车充电器是为插电式电动汽车充电提供电能的基础设施中的元件。低压配电系统上的电动汽车充电器引起的电能质量问题引起了越来越多的关注。在电动汽车大规模运行之前，有必要了解电动汽车充电器对电网的影响。本文对采用SAE 1772标准规定的4个交流电动汽车导电充电器和部分运行的非线性负载的低压配电系统进行了现场测试。讨论了电压/电流趋势、谐波/间谐波、闪烁和电能质量事件的一些测量结果。
