Performance analysis of isolated 3-phase self excited induction generator using graph theory and PSO technique

This paper analyzes the steady state performance of isolated 3-phase self excited induction generator (SEIG) feeding balanced static resistive load. The effects of load and capacitance on magnetizing reactance, frequency, terminal voltage, currents have been shown in this paper. The model equations, which are nonlinear in nature, have been developed using graph theory. These equations can be easily solved by particle swarm optimization method. The performance of this algorithm has been compared with Newton-Raphson method. MATLAB has been used for simulation. The simulated results obtained using these algorithms help in understanding the steady state performance of SEIG.
