Abstract

The direction of modernization of the wind power plant is substantiated, which is aimed at a comprehensive increase in energy efficiency and resource conservation. Taking into account the reasons for the destruction of the teeth of the gear, a constructive scheme of a single-stage gearbox with several output shafts is proposed. This scheme allows you to distribute the output power to several electric machines, which, in turn, reduces the mechanical stress in the area of contact of the teeth of the gears and gears of the output shafts. Due to the division of the output power into several machines, the mass and dimensions of the gearbox are also reduced. The uniformity of power distribution on the shafts can be violated by the discrepancy between the parameters of gears, electromagnetic and mechanical parameters of electric machines. In the proposed design scheme, the uniformity of energy flows along the shafts is ensured by a sequential connection of the phases of the stator windings of electric generators.
