Electromagnetic Calculations For Half-speed Nuclear Power Generators Based on Pole-body Magnetic Potential Method

半转速核能发电机的研发是近期热点,发电机的磁路及参数计算又是此研究领域的关键点之一。目前主要有2种方法(解析法、有限元法)对磁路及参数计算进行计算。而在总体方案选型时,相对于有限元法,解析法则能大大缩短方案选型计算工作量。本文对比了几种常用计算方法,并与试验值对比,得到一种相对可靠的计算方法。

The research of half-speed nuclear power generators is a focus of many recent researches of its kind, while magnetic circuit and parameters estimation of the generator is the key point. So far, there are two prevailing ways to calculate the magnetic circuit and parameters, i.e., the analytical and the finite element analysis( FEA). However, for the overall scheme selection, it is preferable and efficient to use the former one to calculate circuit and parameters, compared with FEA. Comparison is made on the said calculations based on several common-used methods with test value, along with recommendation of relatively reliable method.
