Fluid Stochastic Petri Nets based Modelling and simulation of Micro Hydro Power stations behaviour

The present paper proposes a Fluid Stochastic Petri Nets based model, with a flexible and modular structure, to represent the behavioural characteristics and possible interactions among the controlled Micro Hydro Power units in a run of the river chain. Environmental influences were embedded, the final goal of the proposed modelling method being to simulate the dynamicity of the hydrographic assembly in order to optimize the management of water resources. The proposed approach was developed, the case study of a micro hydropower stations chain situated in the hydrographic basin of Someş river being considered. An UPPAAL based simulation was realized in various conditions corresponding to environmental changes and taking into account the main functioning characteristics of the components. Verified by simulation, control modules were implemented as a part of a SCADA system designed for complex automation of a micro hydropower plant.
