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 investigation on the performance of voltage and frequency controller (VFC) of a wind power generation using a capacitor excited isolated asynchronous generator (IAG) feeding dynamic loads. The amplitude of load currents is estimated using the low pass filter to control the voltage and frequency of IAG system. Three-leg voltage source converter (VSC) with a battery energy storage...
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 presents a design of an isolated star/hexagon transformer based ELC (electronic load controller) to regulate voltage and frequency of an isolated asynchronous generator (IAG) driven by a stand-alone uncontrolled pico-hydro turbine feeding three-phase four-wire loads. The proposed ELC is used to control frequency and voltage of IAG despite frequent change in consumer loads. Such an ELC is...
The application of a doubly fed induction generator (DFIG) as a suitable generating scheme in a remote or isolated communities is presented in this paper. Remote area power supply (RAPS) system, a dummy load and its controller with energy storage system (ESS) are identified as the key components. The dummy load is used to absorb the power associated with over generation. The battery storage system...
