Abstract

The invention belongs to the technical field of wind power generation. In order to solve the problem of low braking effect caused by case vibration and brake disc abrasion when a wind generating set adopts a conventional mechanical brake, the invention discloses a wind generating set adopting hydraulic buffer braking and locking. The wind generating set comprises a hydraulic pump, a hydraulic motor, a wind wheel, a generator, an oil compensating unit, a hydraulic buffer unit and a hydraulic locking unit, wherein a main circulating system which is normally operated can be switched to a brakingcirculating system by virtue of the hydraulic buffer unit, so that buffer braking of the generating set is completed, and the hydraulic pump can be isolated by the hydraulic locking unit, so that thewind wheel and the hydraulic pump are locked. According to the wind generating set, the hydraulic buffer unit and the hydraulic locking unit are used, so that stable buffer braking and locking of thegenerating set can be realized, thereby avoiding vibration, improving the protection of the generating set and guaranteeing a stable braking effect.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a wind power generating set adopting hydraulic buffer braking and locking. Background technique [0002] With the depletion of traditional energy sources in the world in recent years, new energy sources have entered the energy stage one after another. The rapid development of wind power generation has made due contributions to the depletion of world energy and environmental crisis. Therefore, the new hydraulic wind turbine equipment has received unprecedented attention, and it has been tested or put into use all over the world, and will gradually replace the traditional mechanical gear transmission generator set. Among them, the quality of the brake system of the wind power generating set plays a vital role in the normal operation of the entire generating set. The brake system of the wind turbine is mainly used for the safety system of the wind turbine...
