Abstract

The invention relates to an energy-storing type hydraulic wind generating set which mainly comprises a wind wheel 1, a dosing pump 2, a high-pressure pipeline 3, a low-pressure pipeline 4, a variable displacement motor 5, an energy-storing system 6 and a generator 7, wherein the energy-storing system 6 comprises a pump-motor 6.1, an energy storage 6.2 and an energy-storing oil tank 6.3. According to the invention, a pump-motor component and an energy storage device are taken as a secondary converting and storing system for middle energy, so that the energy can be stored and released in real time according to the requirement of the generating set and the energy waste caused by paddle-adjusting and wind-abandoning at higher wind speed is avoided. The energy-storing system has a peak-clipping valley-filling function in the whole generating set, the output power of the generating set is smoother and the electric energy quality of the generating set is effectively increased.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and relates to a main transmission system of a hydraulic wind power generating set, which uses a hydraulic transmission system to replace the traditional gearbox-type and direct drive transmission systems, and particularly relates to an energy storage type hydraulic wind generating set. Background technique [0002] Wind power is one of the most mature, large-scale development conditions, and one of the most promising power generation methods for commercialization. Countries around the world have realized the importance of wind power in adjusting energy structure and mitigating environmental pollution, and have given great support to the development of wind power. highly valued. [0003] From the generation of wind turbines to the present, its transmission system is mainly divided into three transmission forms: gearbox type, direct drive type and hydraulic type that have just appear...
