DESIGN AND DEVELOPMENT OF VOLTAGE REGULATOR FOR 3-PHASE SELF EXCITED INDUCTION GENERATOR

Abstract

An approach to,the design of voltage regulating system for self excited induct-ion generator is presented. The steady state analysis of self excited induction generator has been done with the help of equivalent circuit. ?Newton Raphson Method' has been adopted to solve the nonlinear simultaneous equations which appear during the analysis of the machine, (computer programs have been developed for the computation of unknown variables of nonlinear simultaneous equations and machine performance. The computed results are presented and critically discussed. The selection of various components of voltage regula-ting system has been made for fabricating a practical firing control circuit. The parameters of P and PI- controllers are selected on the basis of experimental observations. The performance study for steady state and transient response has been observed with P and PI-controllers separately to show the response and stability 'of the voltage regulating system. (T extensive tests have 'been performed to study steady state and transient performance of voltage regulating system with P and. PI•-controller, It is observed that c the developed voltage regulator is capable of regulating voltage for adequate load without losing • self excitation.
