摘要
储能变流器的型式试验项目众多,相关标准对部分试验项目的方法及内容缺少必要的规定,导致项目实际测试时不同的机构、不同的检测人员可能带来较大的差异。针对大功率储能变流器在电压、电流总谐波畸变率测试过程中由于负载不同、测试仪表接线方式不同出现的一些异常情况来做一些探讨,旨在引起检测人员的注意,并为储能变流器产品改进及标准完善提供参考。
There are many items of types test for power conversion system,and the relevant standards lack the necessary provisions for the methods and contents of some test items.As a result,different institution and person may cause large differences in the actual test of the project.This article mainly discusses some abnormal situations that occur in high-power power conversion system due to different loads and different wiring methods of test instruments during the test of total harmonic distortion rate,aiming to attract the attention of inspectors and provide reference for product improvement and standard improvement of power conversion system.
