Abstract :
Self-Excited Induction Generators have become the prime choice for wind energy conversion in remote and rural areas due to many advantages over Grid Connected Induction Generators. However, their main drawback is poor voltage and frequency regulation. Steady state analysis for such machines is important to understand their behaviour under varying operating conditions. In this paper steady-state performance of SEIG (with general RL load) under varying operating speed, excitation capacitance and load is presented using a simple and fast nodal analysis and piecewise linearization of magnetization characteristics. Moreover, terminal voltage control of SEIG by means of capacitor switching is investigated. MATLAB is used to simulate the analysis and the conformity between simulation results and other research papers in this field validates the theoretical approach presented in this paper.
