Embodiment Construction

[0035] Embodiments according to the present invention will now be described in detail with reference to the accompanying drawings, examples of which are shown, in which like reference numerals refer to like components throughout.

[0036] A temperature control system for a converter of a wind power generating set according to an embodiment of the present invention may include a main temperature control loop, an auxiliary temperature control loop and a controller. The main temperature control loop can heat or cool the converter by circulating the first circulating medium through the converter. The auxiliary temperature control circuit can include a refrigeration circuit and a heating circuit. The refrigeration circuit can cool the first circulating medium through the solar adsorption refrigeration panel, and the heating circuit can heat the first circulation medium through the solar adsorption refrigeration panel. The controller can selectively control one of the refrigeration ...

Abstract

The invention provides a temperature control system for a converter of a wind generating set and a control method The temperature control system for the converter of the wind power generator includes:a main temperature control loop, which heats or cools the converter by circulating the first circulating medium through the converter; an auxiliary temperature control loop which includes refrigeration circuit and heating circuit, wherein the refrigeration loop solar adsorption refrigeration plate cools the first circulating medium, and the heating loop heats the first circulating medium throughthe solar adsorption refrigeration plate; a controller which selectively controls one of the refrigeration loop and the heating loop. According to the temperature control system for a converter of a wind power generator, the temperature of the first circulating medium flowing through the converter can be more precisely controlled, and the temperature influences of the external environment to the temperature of the first circulating medium can be reduced.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a temperature control system for a converter of a wind power generating set and a control method thereof. Background technique [0002] With the technical development of wind power generators, the requirements for the cost and stability of wind power generators are getting higher and higher. One of the core components of wind turbines is the converter. The converter is a device with high power density and generates a lot of heat during operation. The temperature control of the converter is particularly important during operation. [0003] The existing cooling systems of high-power converters are mainly divided into water-cooling systems and air-conditioning temperature control systems. As far as the water cooling system is concerned, the temperature of the circulating medium of the water cooling system is restricted by the ambient temperature. Specifically, when t...
