用于永磁同步发电机设计的阻抗模型

Impedance Models in Design of Permanent Magnet Synchronous Generator

找到一个既适合电励磁同步发电机的设计又适合永磁励磁同步发电机的设计的模型是很重要的.模型必须满足几个要求:在实际应用中,模型要简单,能进行快速的计算,其可靠性和精确度要达到一定要求.而用来对交流电机进行设计的传统的阻抗模型普遍能够满足这些要求.这里给出了一个用来对永磁同步发电机进行辅助设计的实际可行的阻抗模型.

Selection of models suitable for the design of a synchronous generator with a field winding or magnet excitation is important.Several criteria must be met.First the model must be simple enough to allow expeditious computation with design features in practical use.Second the model must be reliable enough with acceptable accuracy.Conventional impedance models are commonly employed in the design of ac.machines,and can meet the criteria.This paper demonstrates how a practical impedance model can be formed to aid the design of a permanent magnet synchronous generator.
