Modelling of alternating-current machines having multiple rotor circuits

The modeling of a synchronous or an asynchronous machine forms the basis of simulation investigations made with high-powered computers. Many phenomena and processes require corresponding refinement of the models used, and an increase in input in the form of fictive rotor circuits. A method is presented which has been tested out over a relatively long period of time. The general equations contain none of the usual approximations, and can be programmed quite readily. Numerical examples are given as an aid in applying the procedures
