Abstract

The embodiment of the invention provides a hydraulic control system and a wind power generating set. The hydraulic control system is used for the wind power generating set and comprises a hydraulic pump, a hydraulic motor, a first hydraulic channel and a second hydraulic channel. The hydraulic pump is driven by a high-speed shaft of a gear box, and the gear box is arranged in a cabin located at the top end of a tower frame. The hydraulic motor is used for driving a power generator, and the power generator is arranged on the tower frame. The first hydraulic channel communicates with an outlet of the hydraulic motor and an inlet of the hydraulic pump and is used for oil returning. The second hydraulic channel communicates with an outlet of the hydraulic pump and an inlet of the hydraulic motor and is used for oil supply. According to the hydraulic control system provided in the embodiment, long-distance power transmission from the cabin to the power generator on the tower frame is achieved through the design of the hydraulic pump, the hydraulic motor and the hydraulic channels.

Description

Technical field [0001] The invention belongs to the technical field of wind power generation, and particularly relates to a hydraulic control system and a wind power generating set. Background technique [0002] The nacelle of the wind turbine is installed on the top of the tower. The height of the tower is generally tens of meters or even hundreds of meters. This structural feature causes the stator and rotor of the wind turbine to be hoisted to the top of the tower for installation or replacement. The operation is very difficult and requires the help of a large crane. If it is an offshore wind turbine, the height of the tower is higher. Considering that the installation environment is more difficult for offshore wind turbines, ordinary ships cannot carry large cranes, and it is also more difficult Ensure the stability and operational safety of the large crane; and the higher the tower height, the more difficult it is to install and replace the wind turbine. In the process of i...
