| Abstract: | Focusing on the problem of high energy loss and low test efficiency of the existing wind power converter test system, a test method based on loop power feedback was proposed. The basic principles and the structure of the test system were emphasized, meanwhile the hardware and software platform of converter test was built. The proposed system could realize the automatic testing of various characteristic parameters of the converter. Corresponding tests were carried out on the MWclass wind power converter. The test results showed that the system test efficiency was excellent, and the system was easy to operate, safe and reliable, and could realize energy saving and digitization of the converter experimental system. |
