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 an integrated solid state controller (ISSC) for an isolated asynchronous generator (IAG) used in small hydro power generation for feeding three-phase four-wire loads. The proposed ISSC is used to control the voltage and frequency of IAG. This ISSC is realized using a three-leg insulated gate bipolar transistors (IGBTs) based current controlled voltage source converter (CC-VSC),...

This paper deals with a decoupled electronic load controller (DELC) for an isolated asynchronous generator (IAG), used in constant power pico hydro power generation for feeding three-phase four-wire loads. The proposed DELC is used to control the voltage and frequency in the decoupled manner. The proposed decoupled electronic load controller is combination of a voltage regulator (VR) for regulating...
This paper deals with the control of voltage and frequency of an autonomous wind power generation based on isolated asynchronous generator (IAG) feeding three-phase four-wire loads. The proposed control scheme is using the synchronous reference frame (SRF) theory based current detection. The proposed voltage and frequency controller (VFC) consists of a three leg voltage source converter (VSC) with...
This paper deals with the decoupled voltage and frequency controller (DVFC) for isolated asynchronous generator (IAG) used in pico hydro power generation for feeding 3-phase, 4-wire loads. The proposed controller is used to control the voltage and frequency through control of active power at the generator terminal independently. The decoupled controller is a combination of a static compensator (STATCOM)...
This paper deals with the decoupled voltage and frequency controller (DVFC) for isolated asynchronous generator (IAG) used in pico hydro power generation for feeding 3-phase, 4-wire loads. The proposed controller is used to control the voltage and frequency through control of active power and reactive power at the generator terminal independently. The decoupled controller is a combination of a static...
