Electrical Performance Detection System of Electric Vehicle charger

针对目前电动汽车充电机电气性能测试系统存在的问题,提出了高度集成检测系统。提出了一种新的算法,该算法通过改进传统的ip-iq算法和αβ-dq坐标转换频率算法,能在电压不平衡和频率畸变同时发生时的对电流谐波、频率进行精确检测。通过matlab/simulink对该算法进行了仿真验证,介绍了仿真结果。

This paper presents a highly integrated detection system against the current problems of electrical performance detection system of electric vehicle charger.Then it proposes a new algorithm to detect the harmonic and frequency accurately in the same time of occurring voltage unbalance and frequency distortion by improving the traditional ip-iq algorithms and the coordinate conversion frequency algorithm.The algorithm has been verified by matlab / simulink,and the simulation results have been introduced.
