Title:
ROTOR ROTATION CONTROL SYSTEM AND CONTROL METHOD FOR WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2019/127970
Kind Code:
A1
Abstract:
A rotor rotation control system for a wind turbine, comprising: a rotating unit, used for allowing a rotor of the wind turbine to rotate relative to a unit base of the wind turbine; a driving unit, used for driving the rotating unit; and a processor, used for determining a bending moment load switching position on a rotating shaft of the rotor and outputting an adjustment instruction to the driving unit on the basis of the bending moment load switching position, where the driving unit receives the adjustment instruction from the processor and adjusts an operation state of the rotating unit on the basis of the adjustment instruction, thus balancing bending moment load changes at the bending moment load switching position. In addition, also related is a rotor rotation control method for the wind turbine. The system and method effectively avoid vibrations of blade components of the wind turbine during assembly, disassembly, or maintenance.
