Description

technical field [0001] The present invention relates to a pitch system and a yaw system in wind power generation, in particular to a refined simulation platform and method for a wind turbine yaw system and a pitch system, especially a wind turbine yaw system based on RTDS and Bladed Refined simulation platform and method for navigation system and pitch system. Background technique [0002] Pitch system and yaw system are important devices of large-scale wind turbines, which play a vital role in the optimization of power generation and safe operation of wind turbines. Therefore, the research on pitch system and yaw system is very important. However, it is costly to conduct experiments directly on wind turbines, and most researchers do not have the relevant experimental conditions. [0003] In the existing academic research, the pitch system is usually simplified to the first-order lag link of the pitch command. In fact, the pitch system includes pitch control, pitch motor d...
