Embodiment Construction

[0032] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] The invention discloses a 1.5MW wind power generator, which comprises a vertically arranged tower and a wind generator cabin arranged on the tower.

[0034] The wind turbine nacelle is provided with a generator connected to the rotor blades, and a wind turbine gearbox mechanically connected to the output end of the generator. A gearbox lubricating and cooling system is provided on the lubricating oil circuit of the fan gearbox. The gearbox lubricating and cooling system includes a common radiator arranged on the lubricating oil circuit of the fan gearbox. The common radiator is used to reduce the lubricating oil of the fan gearbox temperature to ensure the stable operation of the wind turbine.

[0035] From the analysis of the principle of the lubrication and cooling system of the gearbox of the 1.5MW fan, in order to improve the heat ex...

Abstract

The invention discloses a wind driven generator. A gear box lubricating and cooling system comprises a common radiator and an auxiliary radiator which are arranged on a fan gear box lubricating oil way. An axial flow fan is arranged on the outer wall of a tower and/or a wind driven generator room, and introduces low-temperature air outside into the tower and/or the wind driven generator room. According to the wind driven generator, because the auxiliary radiator is added into the gear box lubricating and cooling system, the heat exchange area of a radiator assembly is increased, and the heat exchange capability of the radiator assembly is improved; because the low-temperature high-flow air outside is introduced into the wind driven generator room in a forced mode through the axial flow fan, the environment temperature inside the wind driven generator room is controlled, the heat exchange capability of the air-cooling radiators of the lubricating and cooling system is improved, and it is guaranteed that the whole fan can generate power normally with full power.

Description

technical field [0001] The invention relates to the field of new energy and energy saving, in particular to a control method for a lubricating and cooling system of a wind power generator and a gearbox thereof. Background technique [0002] At present, when the 1.5MW fan generates power at full power, the oil temperature of the gearbox exceeds the limit value required by the main control system, which is mainly caused by the following three reasons: [0003] ) low mechanical efficiency of the gearbox [0004] The gearbox of Sinovel 1.5MW fan adopts the lubricating and cooling system of HYDAC. The lubricating and cooling system of HYDAC is designed for foreign gearboxes. The mechanical efficiency of foreign gearboxes is >97%, and its heating power is about At 50kW / h, it can meet the normal operation of foreign gearboxes. However, the domestic gearbox used in this fan is generally much lower in mechanical efficiency than foreign gearboxes due to problems such as gear proc...
