摘要
同步发电机负载时,为了考虑电机旋转和定子电流对电机磁场分布的影响,把整个电机模型作为求解区域,对转子旋转360°电角度空间范围内每一定、转子相对位置进行电磁场有限元分析。文章介绍了减少二维电磁场有限元分析次数的方法和准确计算定子绕组电压的方法,最后用ANSYS软件编程计算验证了方法的正确性。
The distribute of electromagnetic field is varied because of the effects of the revolution of generator and the current of stator windings.The whole generator model is the area of analysis by use of finite element method,rotating the rotor within the range of 360 electric degree.The methods to reduce the calculate quantity of electromagnetic field and to calculate the stator windings voltage are put forward in this paper.The methods are verified by the result of the program base on ANSYS.
