RUI: Software Models of Rotating Electrical Machinery

该项目是建立一个旋转电机在电机或发电模式下随时间变化的有限元软件模型。这些模型的目的是模拟那些条件，如突然短路，非正弦输入到机器，不平衡运行等，不能完全分析现有的模型。尝试了三维场分析、网格动态适应转子运动、转矩计算等新技术。多年来，人们开发了旋转机器的模型来分析各种情况。不同的模型适用于研究不同的条件。随着大型计算机的出现，寻找适用于所有条件的更广义模型的尝试已经取得了重大进展。更有效和准确的模型是这个项目的目标。

The project is to build a finite element software model over time of a rotating electric machine, in either motoring or generating mode. The purpose of these models is to simulate those conditions such as sudden short circuits, nonsinusoidal inputs to the machine, unbalanced operation, etc. which cannot be completely analyzed by presently available models. Several new techniques for analyzing fields in three dimensions, adapting the mesh dynamically with rotor motion, and computing torques will be tried. Models of rotating machines have been developed over the years to analyze various conditions. Different models work well for studying different conditions. Attempts to find more generalized models that would be good for all conditions have made significant progress with the availability of large computers. More efficient and accurate models are the goals of this project.
