摘要
针对双馈风电机组高温限功率停机的问题,根据空气动力学原理,提出机舱降温系统设计方法。其中,聚风罩和变频器柜自动通风快速响应系统为本系统设计的关键部分。文章详细阐述了聚风罩的设计方法和受力分析,系统采用PI调节器实现控制的快速响应。该系统实验阶段安装于1.5 MW风电机组,通过现场数据采集及分析,结果验证了该系统的可行性和稳定性,系统可满足机舱温度<40℃,变频柜内温度<45℃的工作要求,实现机舱自动降温功能。
Aiming at the problem of outage of dual-feedback induction generator(DFIG)based wind turbines due to high temperature limiting power, according to aerodynamics, the design method of the cooling system is presented in this paper. The design of wind gathering hood and the automatic ventilation fast response system of the frequency conversion cabinet are the key parts of this system. In this paper, the design method and the force analysis of the wind gathering hood are expounded, and the system adopted PI regulator to realize the fast response of control. During the test phase,the system was installed on the 1.5 MW wind turbine generator. Through collection and analysis of the field data, the results can verify the feasibility and stability of the system. In addition, the system can meet requirements that the room temperature is less than 40 ℃ and the temperature in frequency conversion cabinet is less than 45 ℃. It can also realize the automatic cooling function of the room.
