Establishment of a Pico Hydro Power Plant Using Permanent Magnet Synchronous Generator Supplied for AC Microgrid

The objective of this paper is to establish the pico hydro power plant-based the permanent magnet synchronous generator (PMSG) for supplied to AC microgrid. The developed system consists of the pelton turbine, the PMSG, and the power and control circuit. The experiments were carried out under the no-load condition using the PMSG-based pico hydro power plant prototype, given the variable operating speeds of Pelton turbine. The experimental results, including terminal voltage of PMSG, dc-bus voltage at several operation speed, and inverter output voltage, are graphically measured. More importantly, the experimental findings are to be further apply to the design of an optimal control scheme for the grid-connected Pico hydro power plant in our subsequent research.
