Research on Wind Turbine Blade Static Loading System and its Variable Traction Control Mode
According to MW-class wind turbine blades loading system requirements, the load requirement of traction apparatus under the different operating conditions were discussed. At the same time, the variable traction feature of traction apparatus was analyzed. A multi-node hydraulic loading system based on CAN bus was designed in this paper. In order to improve the precision of traction and the following performance of loading system, opting for the “V-F” control mode, we proposed the variable proportional separate integral control algorithm with amplitude limit to enhance the system's adaptive capacity. Experiments show that this program has a good coordination feature in the variable traction control, and fully meets the requirements of blade loading test.
