[Abstract]:Wind power controller is the core and foundation of wind power equipment, and its stability and reliability play a decisive role in the safe operation of the equipment. At present, many wind power equipment often work in the field environment of high and low temperature and high humidity, which will pose a severe challenge to the reliability of wind power control devices. Based on the operating environment of wind power equipment, a set of environmental test platform is developed for wind power controller parts temperature and humidity test. The specific research is as follows: 1. The overall scheme design of the environmental test platform and the structural design of the test box and the air volume measurement section. According to the environmental requirements of wind power equipment, the overall scheme of environmental test platform for temperature and humidity control is designed, and the test box, refrigeration system, heating system and humidity system are established. Closed circulatory system. 2. Based on the requirements of the design parameters of the test bed, the working modes of refrigeration system, humidification system and heating system are designed by using the theory of hydrodynamics and engineering thermodynamics. The cooling load of the refrigeration system and the heat load of the heating system are calculated. Humidification of the humidification system. Based on fluent software platform, the flow field, temperature field and humidity field in the environmental test box are numerically simulated by numerical simulation method. The whole structure design and test verification of the test bed. Based on the results of theoretical and simulation analysis, the whole structure of the environmental test platform is designed, and the 3D prototype model is established. The test platform has been tested by customers, and the test platform has been delivered to Beijing Tiancheng Tongchong Electric Co., Ltd.
