Performance of electrical machines is critically affected by the saturating nature of ferromagnetic materials. In order to have a reliable and accurate estimation of the steady-state behavior of synchronous machines, it is important to have a precise machine model that includes saturation. This paper aims to develop a new synchronous machine model incorporating an accurate saturation model. The algorithm used in this paper to represent magnetic saturation calculates the coefficients in several real function expressions for the saturation characteristics of a synchronous machine. The new synchronous machine model proposed in this paper has been used in the investigations to calculate the machine behavior in various operating conditions.
