Description

technical field [0001] The invention relates to an in-the-loop comprehensive test platform for a wind turbine pitch control system. Background technique [0002] Wind power generation is a relatively mature technology for the development and utilization of new energy. In order to improve the efficiency and quality of wind power generation, variable speed constant frequency power generation technology has become the mainstream technology of wind turbines. Pitch technology and frequency conversion technology are two key technologies for variable speed and constant frequency power generation. Among them, the pitch technology plays a very important role in improving the efficiency of wind turbines, the quality of power generation, and the safe operation of generators. Therefore, the performance of the pitch control system is the key factor to determine the normal operation of the wind turbine system. [0003] With the rapid development of the wind turbine industry and the incr...

Problems solved by technology

[0004] Although the domestic wind turbine pitch system test platform has begun to be used, due to the low starting point, most wind turbine pitch test platforms have a single test function and are not convenient to expand

And there is still a lack of effective laboratory testing methods for the main control system of the fan

The traditional test method is to carry out on-site simulation through the wind turbine in the field, but because the wind is unpredictable and the requirements for the wind are lack of controllability, the traditional method takes a long time to test, and it is difficult to comprehensively test the pitch system of the wind turbine in each Operating conditions under working conditions
