New Parameters Estimation Using Numerical Method and Steady State Performance for Convensional and Converter Fed Induction Motor

Chetana P. Sangani

Abstract: The work proposes a method for parameter estimation of induction motor and steady state performance for conventional as well as converter fed induction motor, based on equivalent circuit method. The method, which requires a no-load and a blocked rotor test, is intended for steady state performance i. e. torque, efficiency, full load current, output power, power factor of three-phase squirrel cage induction motor within the rated range of operation. Data of the tests (No load test, Block rotor test, Full load test) taken from ERADA laboratory, and also simulate for conventional as well as converter fed induction motor using MATLAB-SIMULATION. Programming for estimation of parameter using numerical procedure Newton-Raphson method and determining steady state performance of induction motor algebraically and graphically (using circle diagram).
