The present invention relates to the field of new energy access and control, and particularly to a test system for the power grid adaptability of a mobile wind turbine generator system. The test system comprises: a power grid disturbance generation device and an integrated measurement and control device which are connected by optical fibres, wherein the power grid disturbance generation device is connected between a medium-voltage power grid and the high-voltage side of a boosting transformer of the wind turbine generator system; and the power grid disturbance generation device and the integrated measurement and control device are integratedly installed in a container after being integratedly designed. The container comprises a heat dissipation system, which comprises a water cooling device and an air cooling device. According to the present invention, a common power grid disturbance is generated on an online real simulation at the high-voltage side of the boosting transformer of the wind turbine generator system, actual operating data of the wind turbine generator system is collected and analyzed, and the power grid adaptability of the wind turbine generator system is tested and evaluated. The mobile structure is conveniently transported and installed among different wind farms, thereby solving the problem of testing and detecting the power grid adaptability of the wind turbine generator system in complex terrain and transportation conditions on site.
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...
