Studi Penempatan Kapasitor Eksitasi Pada Generator Induksi Satu Fasa
Abstract
Single phase induction motor can only operate as a single-phase self-excited induction generator (SPSEIG) when the rotor is rotated above synchronous speed, as well as auxiliary windings and / or main windings is connected capacitor excitation. This paper analyzes the influence of the placement of excitation capacitor on the performance of SPSEIG, which include: voltage and frequency generator. Computer simulation results compared with the results of laboratory testing to verify the accuracy of the models and methods of analysis are proposed. Based on test results and simulation, the use of two capacitors excitation coil mounted in the main and auxiliary windings produce best performance of voltage and frequency stability. The use of a capacitor excitation in the main windings will cause relatively high voltage drop when loaded.
