Abstract :
This paper deals with a voltage and frequency controller for an isolated power generation system based on asynchronous generator (AG) driven by pico hydro turbine and supplying 3-phase dynamic (asynchronous motor) loads. The proposed controller is a combination of a static compensator (STATCOM) and an electronic load controller (ELC) for independent control of the reactive and active powers of the system to control the voltage and frequency respectively. The proposed generating system along with its controller is modeled in MATLAB using SIMULINK and PSB (Power System Block Sets) toolboxes. The performance of the controller is verified with direct on line starting of a 3-phase asynchronous motor.
