In the testing of permanent magnet wind turbines, the frequency conversion test system should have the following characteristics:
1. Low frequency fundamental wave test function in a wide frequency range.
High frequency means it contains harmonics, and low frequency means the fundamental frequency is very low, down to 1 Hz.
2. Wider current test range.
The no-load current of permanent magnet motors is very low. The no-load current of large capacity units is only about 0.005 to 0.01 times the rated current. Overload current should also be tested. The maximum current is often 200 to 300 times the minimum current. Times
AnyWay broadband power test system developed by Hunan Yinhe Electric Co., Ltd. can better meet the frequency conversion testing needs of permanent magnet wind turbine testing. benches. Major national energy companieswind energy companies such as Goldwind Technology, Dongfang Electric, Xiangtan Electric and China South Locomotive & Rolling Stock Corporation all use this test system.
