Power flow and efficiency analysis of three-phase induction generator for grid connected system

This paper presents a power flow model of induction generator for grid connected system. In order to determine the power of induction generator that flow to the electrical distribution system. Parameters of a three-phase squirrel cage induction motor in which obtain from stator, rotor and iron-core are used in characteristic analyzing. There parameters are also employed to establish a mathematical model of the induction generator. The simulation results from the proposed model are compared to the results of the implemented testing set in the laboratory. Then the efficiency of the generators is discussed. From the experimental results, it is found that the model simulation provided power flow results tend to be the same as the testing set with efficiency of 80%. Consequently, it can conclude that the proposed model can be use for induction generator sizing selection.
