Abstract

This project will focus on design and development of water controller for small scale hydro generating units based on fuzzy logic approach. Fuzzy logic is a problem solving methodology that lends itself to implementation system ranging from simple, small, embedded micro controller to large, networked and controllable system. In this project, method of fuzzy logic will be applied to water level controller for small scale hydro generating units. Small scale hydro generating units, typically under 10MW, generate electricity or mechanical power by converting the power available in flowing water in rivers, canals or streams. The principle requirements of small scale hydro generating unit are suitable rainfall catchments area, transporting water from intake to the turbine, such as a pipe. Application of fuzzy logic is based on the control strategy that can be written in IF-THEN rule form, which is highly conformable to the human logic. The condition of the water level will be expressed by fuzzy set. Model analysis is given to demonstrate the effectiveness of the fuzzy logic control. A series of simulations will be carried out to show the performance of fuzzy logic approach for water level controller. The water level will be controlled and maintained at a certain value to make sure the hydro generating unit functioning properly.
