Multiparameter Stability Analysis of Systems with Induction Motor Loads, Weak Interconnections and Series Compensation
Authors: , ,
Abstract: Dynamic modeling and stability domain analysis of a system consisting of a synchronous generator supplying an induction motor load through a series compensated weak network has been carried out in this paper. The impact of X=R ratio of the feeder and generation control system parameters on the stability domain with respect to series compensation has been examined through eigenvalue calculations and time domain simulations. From the studies conducted, it was observed that the stability domain of the system with respect to series compensation depends on the grid strength in addition to the excitation system parameters. Eigenvalue analysis shows that there is a strong correlation between the exciter gain, time constants of the measurement transducer and exciter, and the series compensation level. The main contribution of this work is to reveal new bifurcations which arise in these systems which has been studied through eigenvalue analysis and time domain simulations for various combinations of system parameters.
