Abstract: This paper presents a new configuration of a voltage and frequency controller for a stand alone pico hydro power generating system employing an Isolated Asynchronous Generator (IAG). The proposed controller is an Electronic Load Controller (ELC), which consists of a three leg IGBT (Insulated Gate Bipolar Junction Transistor) based Voltage Source Converter (VSC), a DC chopper and an auxiliary load at its DC bus. The neutral terminal for the consumer loads is created using a star delta transformer and the proposed system is modelled and simulated in MATLAB using Simulink and PSB toolboxes.

Keywords: stand-alone power generation; voltage source converter; voltage control; frequency control; star–delta transformers; asynchronous generators; pico hydro power; electronic load control; simulation.
