【摘要】:風電控制器件是風電設備的核心和基礎,其穩(wěn)定性和可靠性對設備安全運行起著決定性的作用。目前許多風電設備常工作于高低溫及高濕的野外環(huán)境,這些環(huán)境將對風電控制器件的可靠性造成嚴峻挑戰(zhàn)。本文基于風力發(fā)電設備的工況環(huán)境,開發(fā)了一套用于風電控制器件溫濕度試驗的環(huán)境試驗平臺。具體研究內如下:1.環(huán)境試驗平臺總體方案設計及試驗箱和風量測量段的結構設計。根據(jù)風電設備的環(huán)境工況要求,設計了可進行溫濕度控制的環(huán)境試驗平臺的總體方案,建立了由試驗箱、制冷系統(tǒng)、加熱系統(tǒng)、濕度系統(tǒng)、風道測量段串聯(lián)連接的閉式循環(huán)系統(tǒng)。2.基于試驗臺的設計參數(shù)要求,應用流體力學以及工程熱力學理論設計了制冷系統(tǒng)、加濕系統(tǒng)、加熱系統(tǒng)的工作方式,計算了制冷系統(tǒng)的冷負荷,加熱系統(tǒng)的熱負荷,加濕系統(tǒng)的加濕量。3.利用數(shù)值模擬方法,基于Fluent軟件平臺,對環(huán)境試驗箱體內的流場、溫度場、濕度場進行了數(shù)值仿真,通過仿真分析確定了試驗箱采用側向帶繞流件的送風方式。4.試驗臺的整體結構設計及試驗驗證;诶碚摵头抡娣治鼋Y果完成了環(huán)境試驗平臺整體結構設計,建立了三維樣機模型,并在完成產品制造調試后對試驗臺進行了試驗驗證。本試驗平臺經(jīng)客戶測試,各項指標均符合設計要求,并且該試驗臺已交付北京天誠同創(chuàng)電氣有限公司使用。
[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.
