摘要:

针对目前风电行业中较常见的变频柜等电气元件下置的方案,进行了优势分析和缺点比较。以质量、动量和能量守恒定律以及标准湍流模型为建模理论基础,通过CFD流体软件的计算,对塔筒底部变频柜工作环境的速度场和温度场进行了数值分析。通过分析结果可以得出,加装了轴流风机进行强制通风换热的塔筒底部空间的温度环境能够满足变频柜等各个电气部件正常工作的要求,同时,结合结构设计和布局中的不合理之处,提出建议改进。本文提出的塔底空间风冷散热方案的计算,不仅对风电机组结构布局的合理性有着重要意义,对风电机组机舱内及各个散热部件的计算也具有一定的借鉴价值。

Abstract:

For the current wind power industry, the more common converter cabinet and other electrical components under the program, the advantages of analysis and comparison of shortcomings. Based on the law of mass, momentum and energy conservation and the standard turbulence model, the velocity field and temperature field of the working environment of the converter cabinet at the bottom of the tower are analyzed by CFD fluid software. Through the analysis of the results can be obtained, the installation of axial fan for forced ventilation heat transfer tower bottom space temperature environment to meet the frequency cabinet and other electrical components of the normal work requirements, combined with structural design and layout of the unreasonable To make suggestions for improvement. The calculation of air cooling and cooling scheme in the bottom of the tower is not only important for the rationality of the wind turbine structure, but also has some reference value for the calculation of the heat dissipation parts in the engine room.

Key words: Tower bottom, wind turbine, frequency converter, temperature field
