Description

technical field [0001] The patent of the present invention relates to a test system and method for simulating the actual operating state and environment of the pitch system of a wind power generator during the loading test process. Background technique [0002] The pitch system not only regulates the power generation of the wind turbine, but also guarantees the normal start and stop of the wind turbine and emergency shutdown. Therefore, the performance of the pitch system is related to the stability and safety of the wind turbine. Therefore, the performance of the pitch system is Detection becomes very necessary. Due to the limited detection methods of the current wind turbine pitch system, generally a simple drag test, there is no detection system and method that can more completely simulate the actual operation of the pitch system. Contents of the invention [0003] The technical problem to be solved by the present invention is to aim at the deficiencies of the prior ar...
