Simulation of a Doubly-Fed Induction Generator with hydro turbine for electrical energy production

International audienceIn this paper, the authors propose a behaviour simulation of a micro power station system for electric power generation in isolated equatorial regions, e.g. Africa and South America. These remote areas have usually a good potential of hydroelectric relative to small community or activity need. They are characterized by sufficient rainfall, which leads to the steady average flow of the rivers. Despite this energy resource the electrical power generation in these regions is more often achieved by the use of diesels generators. The study proposed here deals with a hybrid electrical power station (photovoltaic and hydro turbine based on Doubly-Fed Induction Generator) and diesel generators. Two cases are considered in this paper, the first correspond to active and reactive power management when the Doubly-Fed Induction Generator is coupled to a micro-grid. The second case is based on the stator voltage and frequency control when the hybrid electrical power station ensures energy to isolated electric loads
