An equivalent circuit approach to analysis of synchronous machines with saliency and saturation

An equivalent circuit approach is presented for synchronous machine analysis. The approach provides a detailed treatment of magnetic nonlinearity without excessive computational complexity. The number of parameters is typically in the range of 30 to 100, in contrast with 13 to 19 in conventional linear models and with 2000 to 10000 for finite-element analysis. The models developed are intended for use with digital simulation software in the solution of transient, asynchronous, and synchronous steady-state situations.<
