Load Frequency Control with Fuzzy Logic Controller Considering Non-Linearities and Boiler Dynamics B. Anand1 and A. Ebenezer Jeyakumar2 1Hindusthan College of Engg & Tech, Coimbatore, India 641 032 2Formerly Principal, Government College of Engg, Salem, India 636 011Abstract This paper describes the Load Frequency Control (LFC) of two area interconnected reheat thermal system using conventional Proportional – Integral (PI) controller and Fuzzy Logic Controller (FLC). The system is incorporated with governor dead band, generation rate constraint non-linearities and boiler dynamics. The conventional PI controller does not yield adequate control performance with the consideration of non-linearities and boiler dynamics. To overcome this drawback Fuzzy Logic Controller has been employed in the system. The aim of FLC is to restore the frequency and tie line power in very smooth way to its nominal value in the shortest possible time. Time domain simulations are used to study the performance of the power system. System performance is examined considering 1% step load perturbation in either area of the system. Keywords: Area Control Error, Fuzzy Logic Controller, Governor Dead Band, Load Frequency Control, Proportional-Integral. (
