Liquid-cooled wind generating set and temperature control system thereof

Abstract

The invention provides a liquid-cooled wind generating set and a temperature control system thereof. The temperature control system comprises a plurality of temperature detection parts, a plurality offirst heat exchangers, ground source heat exchange equipment, a circulating pipeline, supercharging equipment and control equipment, wherein the multiple temperature detection parts are used for monitoring the actual measurement temperature values of N heat source parts; the multiple first heat exchangers exchange heat with a plurality of corresponding second heat exchangers arranged on the multiple heat source parts; the circulating pipeline is arranged in the wind generating set and communicates with the multiple first heat exchangers and a third heat exchanger of the ground source heat exchange equipment; and the control equipment is used for controlling the working states of the multiple first heat exchangers, the ground source heat exchange equipment and the supercharging equipment according to the N actual measurement temperature values corresponding to the N heat source parts and the N preset target control temperature values corresponding to the N heat source parts. Accordingto the scheme, a unit area temperature control device of natural resources can be fully utilized, so that systematic temperature control and lower energy consumption of the unit are achieved.

Description

technical field [0001] The invention relates to the technical field of wind generator cooling, in particular to a liquid-cooled wind generator set and a temperature control system thereof. Background technique [0002] A wind turbine is a device that converts wind energy in nature into electrical energy, and the corresponding electrical energy belongs to green and clean energy. With the increasing capacity of wind turbines, the heat loss of various subsystems and components of the unit itself is increasing. According to incomplete statistics, the heat loss of the unit itself accounts for almost 8% to 10% of the unit's single capacity. For example: For a unit with a single unit capacity of 10MW, the heat loss value of the unit itself is as high as nearly 1MW, which shows that the heat loss value is quite considerable. A problem directly brought about by the huge heat loss is the problem of heat dissipation, that is, how to efficiently and quickly dissipate the heat generated...
