Abstract

The invention discloses a black start device and method of a wind generating set and the wind generating set, and belongs to the technical field of wind power generation. The black start device of the wind generating set comprises a first power converter and an energy storage device, and the energy storage device is connected with a direct current bus in a converter of the wind generating set; the first power converter is connected with a first load of the wind generating set through the first power converter, a grid-side inverter of the wind generating set is connected with a second load of the wind generating set, the first load is a load which affects the starting of the converter, and the second load is a load which does not affect the starting of the converter. By the adoption of the black start device and method of the wind generating set and the wind generating set, black start of the wind generating set can be achieved, the sustainable operation capacity of the wind generating set is improved, and equipment safety is guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of wind power generation, and in particular, to a black start device and method for a wind power generator set, and a wind power generator set. Background technique [0002] With the development of wind power generation technology, the use of wind turbines has become more and more extensive. Wind turbines are no longer limited to providing electrical energy for onshore loads, and have gradually shifted to provide electrical energy for offshore loads. Among them, the current operation of wind turbines usually relies on the power supply from the external power grid. In some special scenarios, the external power grid may not be able to supply power for the operation of the generator set normally. For example, the power grid fails or there is a typhoon on the sea. Safety considerations Disconnecting the external power grid, etc., will lead to the shutdown of the wind turbine at this time, thereby endang...
