Abstract

The invention belongs to the technical field of wind power generation and particularly discloses a self-feeding type wind generating set. The self-feeding type wind generating set comprises a cabin, a first impeller and a second impeller. A first power generator, a second power generator and an off-grid converter are arranged in the cabin. The first impeller is arranged on the cabin. The first impeller is in transmission connection with the first power generator through a spindle. The second impeller is arranged on the cabin. The second impeller is in transmission connection with the second power generator through an impeller shaft. The second power generator is electrically connected with the off-grid converter. According to the self-feeding type wind generating set, the electric energy of an electric grid does not need to be consumed, and power can be directly supplied to power generating set equipment; and in addition, under the condition that the electric grid breaks down and is powered off for maintenance, the self-feeding type wind generating set can still serve as a standby power source for a power plant and household electricity of surrounding residents.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a self-feeding wind power generating set. Background technique [0002] At present, domestic and foreign wind power generators need to take power from the grid to realize the automatic operation of the unit. When the unit fails to meet the power generation conditions such as shutdown or small wind cut-out, some equipment on the unit (such as: heating, Cooling equipment, control system) still need to consume power from the grid to achieve continuous operation, reducing the overall power generation efficiency of wind turbines. Contents of the invention [0003] In order to solve the above problems, there is a need for a kind of electric energy that does not need to consume the power grid, which can directly supply power to its own generator set equipment, and can still be used as a living source for the residents in and around the power plant when the po...
