Abstract:
The main objective of this project is to take the first steps in designing power plants governor in Iran. In this work, we obtain a realistic model of a hydro-power plant including hydraulic characteristics from the dam to the outlet tail water, mechanically including: the turbine, the gates and all mechanical and dynamic parts, and electrically including generators, transformers and the consumption network. The model is used to simulate different working modes of turbine operation. The Bond Graph method is used for deriving the system equations and MATLAB software for simulations. A conceptual design of the governor is done and the governor model is combined with the turbine model. Using this model, proper control actions are selected for each operating mode and the effectiveness of control actions are evaluated. The final goal is to obtain the major governor design specifications for the design of a functional governor for a given power plant. It was found that a proper PID controller can successfully reach our performance requirements.
