HYDROPOWER GENERATOR SPEED REGULATION USING FUZZY LOGIC SCHEME

Abstract

The instability of power supply is related to slow rotation of hydropower turbine. To overcome this development, a membership function that will analyze the causes of sluggish turbine rotation and increase the rotation of the turbine need to be designed. This will result to generation of fuzzy rule-based system that will regulate and ensure constant output power thus improving the turbine speed rotation. A Simulink based model for Hydropower generator speed control using fuzzy software is applied and the result obtained confirmed a stabilized output power supply as a result of increase in turbine speed rotation and also increase in the rate at which water flows through the hydropower penstock when fuzzy logic scheme is integrated in the model. The stabilized turbine speed rotation when fuzzy logic controller is introduced shows supremacy over other conventional techniques used
