This paper provides a computational analysis of wind impact on different geometric configurations of Savonius turbines proposed and previously studied in specialized literature. As a result of comparative analysis of turbines, we performed a flow analysis over a microturbine array, proposed a twisted Savonius turbine respecting its original profile, and subjected it to a comparative analysis of...

In the following a dynamic mathematical model of a generic cogeneration plant with microturbine is described and the corresponding regulating system is realized. The chief aim of this model is the evaluation of the services such a system is able to provide to an interconnected electric network, both in normal operation and in case of wide perturbations, or to an islanded grid in consequence of ...

Utility restructuring, technology evolution, public environmental policy, and expanding power demand are providing the opportunity for microturbines and fuel cells to become important energy resources. Deregulation has begun to allow for the provision of various ancillary services, such as load-following. In order to investigate the ancillary services ability of these units in distribution syst...

Old hydroelectric power stations often provide unsafe migration routes to fish, apart from passing through mobile gates during high flow. The installation of retrofitted bypass is considered be a potential solution improve fish passage at such old structures, but their performances are insufficient. In the Amblève River (Belgium), 3.3 m dam feeds two principal Francis turbines (12 + 14 m3 s?1) ...
