Problems solved by technology

[0002] When the wind turbine is running, part of the electric energy generated by it is used to power its own auxiliary system; and in the absence of wind, some internal systems need to continue to operate, so the power grid is required to supply power to it, and the wind turbine becomes a net energy-consuming device; When the wind turbine is started, it needs power from the power grid to complete the start-up, so the start and stop of the wind turbine needs power from the power grid, which wastes power resources of the power grid; A photovoltaic power supply device for starting and stopping wind turbines with high efficiency is very necessary
