50 percent. Wind power direct-drive permanent magnet generators have become the mainstream technology in the wind power industry. They have the advantages of simple structure, high reliability, and high conversion efficiency. The application of wind power direct-drive permanent magnet generators in wind power projects will be further popularized and increased. As of December 12, 2023, the new share of wind power direct-drive permanent magnet generators will account for 50%.
What domestic wind turbine manufacturers are there?
In the test of permanent magnet wind turbines, the frequency conversion test system must have the following characteristics:
1. Broadband Low frequency fundamental wave test function within the range.
Broadband means that it contains harmonics, and low frequency means that the fundamental frequency is very low, as low as 1Hz.
2. Wider current test range.
The no-load current of permanent magnet motors is very small. The no-load current of large-capacity units is only about 0.005~0.01 times the rated current. The overload current must also be tested. The maximum current is often 200~300 times the minimum current. Times
The AnyWay broadband power test system developed by Hunan Yinhe Electric Co., Ltd. can better meet the frequency conversion test needs of permanent magnet wind turbine test benches. Domestic large wind power companies such as Goldwind Technology, Dongfang Electric, Xiangtan Electric, and China South Locomotive & Rolling Stock Corporation all use this test system.
The main manufacturers of large wind turbines include:
1. Goldwind Technology
2. Sinovel Wind Power
3. Dongqi
Others are relatively smaller, so I won’t list them all.
Small wind turbine:
Guangzhou Hongying
China Wind Power
Zhongke Hengyuan
