| The generated voltage of the self – excited induction generator (SEIG) depending on the wind velocity fluctuations , load variations and is mainly depend on choosing the proper value of excitation capacitor .This value is very crucial for the self-excitation and voltage build-up as well as voltage regulation in an SCIG. This paper presents simple and accurate approach to compute the minimum value of capacitance required for initiating the voltage build-up and maximum value which the machine fails to self excitation in a three-phase slip ring induction generator and also attention is focused on the influence of external rotor capacitance along with the excitation capacitance which were used to achieve the reactive power requirements and observing their effect in building up the voltage. In this paper is the new method proposed based on the dq Model techniques is developed to find the capacitance requirement under R-L load and resistive load. | ||
