This paper presents a comprehensive analysis of performance characteristics under varying load condition for asynchronous generator. Performance of asynchronous generator depends on variation in prime mover speed, excitation capacitance and load. Estimation of magnetic characteristics involve complicated mathematical computation due to nonlinear nature of magnetization curve. It provides an opportunity to model nonlinear magnetization characteristics to get optimum impedance and optimal capacitance for better performance of asynchronous generator. The nonlinearity of magnetization curve has been analyzed by employing regression functions to estimate magnetization reactance. Thus, optimal value of magnetization reactance is obtained to calculate performance variables of asynchronous generator. Proposed technique provide optimal values of performance variables of asynchronous generator as compared to conventional piecewise linearization model. The effect of solution technique has been discussed while calculating performance variables of asynchronous generator at optimal value of magnetization reactance. Proposed technique of regression function and solution technique is applied on comprehensive data of induction machines as asynchronous generator to prove its validity and accuracy.
