Description

technical field [0001] The invention relates to the field of new energy access and control, in particular to a mobile wind turbine grid adaptability testing system. Background technique [0002] Wind turbines are a multi-disciplinary technology-intensive product, and the adaptability of power electronic devices to weak grids makes them highly sensitive to grid disturbances. However, most of my country's wind power is built in areas with weak power grids, and the quality of power grid operation is poor. Wind turbines that have not been tested for grid-connected operation cannot be normally and safely connected to the grid. The natural properties of wind energy resources, such as volatility and intermittency, and the system complexity of wind turbines and the high sensitivity of the power grid determine that the grid-connected test of wind turbines must be carried out based on actual operation, and laboratory simulations or factory tests cannot accurately and comprehensively r...
