The hydraulic engineering center of Électricité de France (EDF) has for few years been setting up a software platform for modelling and advanced simulation. It covers every field (hydraulics, system control, electrotechnical, civil engineering, and mechanics) and uses the same methods. The modelling of hydraulic infrastructures is done in the Matlab/Simulink/Stateflow environment and relies on a “development repository”, an internal and methodological manual of which the purpose is to standardise programming practices and ease exchanges and knowledge capitalisation. An engineer builds his model drawing in a library of hydraulic and hydromechanic components (impoundments, galleries, weirs, valves, turbines…) and system control components (sensors, filters, controllers, dispatchers…). Then he completes it defining operating scenarios and adding tools to display results and analyse performance.
Several studies have been conducted since 2000. Thanks to advanced control applications developed with this simulation environment, the functioning of several structures in the EDF’s set of equipment has been fixed or optimised, and the maintenance cost has been lowered.
