Simulation of operation modes of inverter hydro-generator

Micro hydropower engineering, due to the relative stability of stream regime and high energy density of water workflow, has the best technical and economic characteristics in comparison to other renewable energy sources. Micro hydropower plants (micro HPPs) meet all environmental requirements and can make a significant contribution to the electrification of remote rural areas, tourist and agricultural facilities. The load operation of hydro-generator comprised of an unregulated propeller hydro-turbine and a synchronous generator through reversible frequency converter was studied. A mathematical model in Simulink (SimPowerSystems) application of the MatLab software package was designed to analyze load operation of a hydro-turbine with a synchronous generator through the inverter.
