中文摘要:

直流充电机系统作为一种重要的能源补给设备,对于电动汽车推广应用具有重要的基础支撑作用。本文通过分析电动汽车直流充电机的系统结构和工作原理,研究建立了直流充电机负荷模型。通过分析充电机交流侧和直流侧的动态过程,理论推导了充电机在吸收电力系统基波功率的同时,会产生一定规律的谐波电流注入。通过研究单台充电机及多台充电机的多谐波源网络模型动态特性,研究了充换电站作为电力系统一个公共耦合点(PCC)所表现的谐波迭代效应。仿真建模和实测结果表明,充电机作为一种新型的非线性负荷,表现出稳态谐波源特点。

英文摘要:

The objective of this paper is to present the system construction and operational principle for a DC charger of electric vehicle. By means of analyzing AC and DC sides for the chargers, a reason was derived theoredically for producing specified harmonic current while absorbing fundamental wave of electric power system. The modeling and measuring procedures of multi-harmonic source for single and multiple chargers were proposed. The summation effect of harmonics for charge/exchange station which was regard as a public coupling circuit(PCC) of the electric power system. The simulation and measuring results indicate that as a new type of nonlinear load, the charger represented a characteristic of steady-state harmonic source.
