Abstract

This paper describes the development of a simple maximum power extracting (MPE) scheme for Wind Electric Energy Conversion System (WECS) comprising of an induction generator, capacitor banks, a diode bridge rectifier, dc link inductor and a line commutated inverter feeding the grid. Steady state analysis of Self Excited Induction Generator (SEIG) is done with the MATLAB programming. The operational speed range of SEIG is decided by proper choice of excitation capacitor banks. MPE is achieved over this speed range by the adjustment of the inverter firing angle that loads the system appropriately to extract maximum power for any given value of input rotor speed. A unique one-to-one relation between per unit rotor speed input and the predetermined inverter firing angle corresponding to MPE has been developed in the form of look-up table. The entire system has been simulated and modelled using the power system block set in MATLAB to obtain the results. The experimental and simulated waveforms validate the system performance.
