Photovoltaic power supply device for starting and stopping wind turbine generator

Abstract

The invention relates to a wind turbine generator start-stop photovoltaic power supply device which comprises a base assembly and a power supply assembly, stabilizing seats are arranged on the left side and the right side of the lower portion of the base assembly, inclined struts are arranged in front of the stabilizing seats, supports are arranged behind the inclined struts, springs are arranged in the supports, and supporting rods are arranged above the springs. A fixing plate is arranged above the supporting rod, a rotating groove is formed in the inner side of the upper surface of the fixing plate, rotating rods are arranged on the left side and the right side of the inner side of the rotating groove, a through hole is formed in the inner side of the rotating groove, a driving shaft is arranged in the through hole, and a planetary gear reducer and a driving motor are arranged on the upper side and the lower side of the driving shaft correspondingly; power generation assemblies are arranged on the left and right sides above the power supply assembly, output assemblies are arranged on the left and right sides below the power supply assembly, and monitoring assemblies are arranged on the left and right sides of the top of the power supply assembly; the device has the advantages that the structure is simple, electric power resources are saved, and the fan operation efficiency is improved.

Description

technical field [0001] The invention belongs to the field of power generation industry-clean energy technology, and specifically relates to a photovoltaic power supply device for starting and stopping a wind turbine. Background technique [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 wind turbine start-stop photovoltaic power supply device with high efficiency is very necessary. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the...
