Optimization Based Performance Evaluation of CEIG for Rural Sites

Abstract The performance of 3-phase CEIG feeding unbalanced load and single-phase load is investigated in this research paper. In this research paper, the performance equations describing the behaviour of the capacitor excited induction generator (CEIG) under unbalanced operating conditions/single-phase load conditions is attained analytically using the concept of symmetrical component theory and the sequence equivalent circuits. The equation representing self-excitation criteria is a non-linear equations having two unknowns (magnetizing reactance X m1 and frequency F). The solution of this nonlinear equation using fsolve technique results in the saturated value of magnetizing reactance and frequency. Using these evaluated values of X m1 and F, the complete performance equations can be accessed from the sequence equivalent circuits. The simulated results are verified experimentally. The results obtained show good resemblance and proved the authenticity of the described scheme.
