| 摘 要： | 温升是考核发电机的一个重要指标。本文首先对常用的几种电机温升计算方法进行了介绍；再以金风科技股份有限公司自主研发的3MW永磁同步发电机为实例，分别采用热路法和有限元方法对其在额定负载条件下的温度场进行了计算，对比误差在5％以内；同时，在3MW电机试验平台上进行了温升试验，将热路法计算结果与实测数据进行了对比，误差也在允许范围内。相比有限元方法，热路法计算温度场的准确性可以接受，同时大大减少计算量与计算难度，可作为永磁电机前期温升设计的校核方法。

| Abstract: | The temperature rise is an important index for the generator.This paper introduces several generator temperature calculation methods.Taking the 3 MW permanent generator designed by Goldwind for example,it calculates the temperature fields of the generator under rated power operation using thermal circuit method and FEM method respectively.The two results error is below 5%.Moreover,it measures the temperature rise of the generator.The data difference between measured and calculation values is within the allo... |
