ANALYSIS OF DIFFERENT CONFIGURATION OF SELF EXCITED INDUCTION GENERATOR IN ISOLATED MODE OPERATION UNDER VARIOUS LOADING CONDITIONS

Abstract

This dissertation deals with the performance analysis of the three phase and single phase Self Excited Induction Generators (SEIG). Steady state analysis of the SEIG is done to predict the performance under different loading conditions. Steinmetz connection is described in this thesis report which is used to feed single phase load from a three phase SEIG. Software matlab simulation of some of the important configurations of SEIG is done. Basically three important configurations of SEIG which is shunt only, short shunt and long shunt configurations are discussed and studied in details in this dissertation. These three configurations of SEIG are used depending upon the requirement of the system. The performance of these configuration differ in many ways from each other which is discussed in details in this thesis report. It is very important to identify the factors like speed, value of capacitance and type of load etc which affect the performance of the SEIG. Slight change in any one of the parameters affects the working and performance of SEIG greatly. Further in this dissertation using FACT devices the control loop operation for voltage control is studied. MATLAB simulink toolbox is used for the purpose to verify the results.
