Performances of three phase induction machine running as induction generator / Kamaruzaman Md Nasir

This thesis presents a report on investigation of performance three phase induction machine when it running as induction generator and characteristics of a three-phase with an excitation capacitor and load. The investigation is focused on the performances of the self-excited induction generator (SEIG) which include speed, torque, output voltage, output current, stator current, load current, output power, phase displacement angle and frequency. The data is measured by varying the speed of prime mover, capacitor value and load. The study also focused on voltage build up process of induction generator driven by a variable speed. The objective is to estimate the optimum values of capacitance required for self-excitation operated as a three-phase induction generators which generate maximum output power. The performance characteristics of different capacitor values for capacitor self-excited induction generator are also compared. Experimental results and performances of the induction machine are presented.
