Temperature control method for liquid-cooled wind turbines

Abstract

The invention provides a temperature control method of a liquid-cooled wind power generating set, the method comprising: obtaining N measured temperature values ​​respectively corresponding to N heat source components in the wind generating set, wherein N is a positive integer; obtaining the N N preset target control temperature values ​​corresponding to the heat source components respectively; according to the measured temperature value corresponding to each heat source component and the target control temperature value corresponding to the heat source component, the heat value or cooling value required by the heat source component is obtained; The calorific value or cooling value required by all N heat source components are summed to obtain the total calorific value or total cooling value required by the wind turbine; according to the total calorific value or total cooling required by the wind generator value, as well as preset multiple energy thresholds, to adjust the operating frequency of the compressor. This scheme can make full use of the unit area temperature control device of natural resources, so as to realize systematic temperature control and lower energy consumption of the unit.

Description

technical field [0001] The invention relates to the technical field of wind power generator cooling, in particular to a temperature control method for a liquid-cooled wind power generator set. Background technique [0002] A wind turbine is a device that converts wind energy in nature into electrical energy, and the corresponding electrical energy is a green and clean energy. With the increasing capacity of the wind turbine unit, the heat loss of each subsystem and component 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 capacity of the unit. For example: For a unit with a 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. One problem directly caused by the huge heat loss is the heat dissipation problem, that is, how to efficiently and quickly dissipate the heat generated by the uni...
