Abstract

The invention discloses a hardware-in-loop testing platform used for a wind power generation electric variable-pitch system, which comprises a platform master control system, a load simulation converter cabinet, a load motor and a human-computer interaction module, wherein the platform master control system comprises an upper computer and a lower computer, and the load simulation converter cabinet comprises a multiaxial servo driver; and the human-computer interaction module is connected with the upper machine. The platform master control system comprises a fan master control system, a variable-pitch control system, an aerodynamic module, a structural dynamic module and a load torque simulation module, and the variable-pitch control system is communicated with the fan master control system through a CAN (Controller Area Network) bus. The testing platform can effectively test the response characteristics of the electric variable-pitch system under wind speed stimulation, the debugging and maintaining cost of the variable-pitch system of a wind turbine generator is reduced, the development time cycle is greatly shortened, and the testing efficiency is increased.

Description

technical field [0001] The invention relates to a hardware-in-the-loop test platform for a wind power generation electric pitch system. Background technique [0002] As the mainstream model, the variable speed constant frequency wind turbine can change the speed of the wind rotor with the wind speed in a relatively wide range, and can use wind energy more effectively. Its advantages have been generally recognized by wind turbine manufacturers and research institutions. However, it is difficult to effectively reduce the impact caused by wind speed fluctuations only through the adjustment of the generator itself. Especially when the wind speed is above the rated wind speed, the wind turbine is very likely to be subjected to a large static or dynamic impact. When an emergency occurs to the wind turbine, the pitch control system can adjust the blades to the 90° position, so that the wind direction is parallel to the blades, so that the blades lose their windward side and realiz...
