Study Of Turbine Governor Controller (Pid) Of Roseires Hydropower Station

Abstract

ROSEIRES hydro power station plays the main role in frequency control of the grid. It is based on the approach that one machine is used for frequency control, although the preferred situation is to have all machines under joint frequency control. Because of the importance of ROSEIRES hydro power station as a grid frequency regulator, the basic control loops comprised mainly of the PID controller are studied here. This thesis is carried out using MATLAB as a simulation tool language, and SIMULINK block diagrams as an interactive environment for modeling, and simulating a wide variety of dynamic system. The study draws attention to the electro hydraulic governor, describing the PID controller and the components influencing stability like PSS, the dynamic modeling of the Gov, Gen, AVR and AVR plus Gen. Optimization of PID parameters for machines at ROSEIRES focusing on Island operation mode and interconnected operation mode. A comparison was made between findings and existing PID settings, resulted in a huge differences.
