Abstract: 

There are a number of secondary effects in a synchronous machine which are most often neglected to develop a simplified model. This procedure is simple and straight-forward, but it gives rise to much errors. To avoid the errors, the modelers have developed several techniques. Saturation is one of the secondary effects which become quite dominant at certain load conditions. In the earlier regimes, grapho-analytical techniques were developed to treat the effect of saturation. But such methods were tedious, complex and time-consuming. Now they should be replaced by computer methods. This paper gives a comprehensive discussion on the various methods developed to treat the effect of  saturation. It also gives computer-aided methods to replace the older methods.

Keywords: 

Saturation, Grapho-analytical Technique, Exponential Method, Frolich’s Equation, Method of Least Square.
