This paper deals with the application of enhanced phase locked loop (EPLL) technique for the voltage and frequency controller (VFC) in a stand-alone wind energy conversion system (WECS) using an isolated asynchronous generator (IAG) feeding three-phase four-wire loads. The fundamental component of three-phase load currents is extracted using EPLL. The EPLL is also used for estimation of the frequency...
This paper deals with the implementation of a controller for an isolated wind energy conversion system (WECS) using an isolated asynchronous generator (IAG) feeding three-phase four-wire loads. The reference source currents are computed using the power balance theory to control the voltage and frequency of WECS. Three-leg voltage source converter (VSC) with a battery energy storage system (BESS) is...
This paper deals with a voltage and frequency controller (VFC) of a stand-alone wind energy conversion system using an isolated asynchronous generator (IAG) feeding three-phase four-wire loads. The reference generator currents are estimated using the power balance theory to control the voltage and frequency of IAG system. Two-leg reduced switch integrated voltage source converter (VSC) with a battery...
This paper deals with the evaluation on loading effect of series resonance circuit at the point of common coupling (PCC) of an asynchronous generator. Effect of frequency variations on series resonance circuit and its effect on input side of the uncontrolled rectifier have been investigated experimentally. The result shows power factor has been improved even though load current is lagging behind the...
