This work presents the assembly and modeling of a plant constituted by one turbine and one synchronous generator to function as a part of a Micro Hydroelectric Plant (MHP) for small isolated systems. Once the assembly of the plant at the laboratory was cons-tructed, has started the developing of an empirical model of the process in the form of reaction curves, obtained by the use of the step response technique that allowed the approximation ofthe main variables involved in a first order with dead time model. After obtaining the transfer functions of the plant, a PID controller was designed in order to maintain the output voltage ofthe generator on an appropriate reference value forelectri-cal distribution in the network ofthe isolated electric system. With the purpose of validate the simulation results, curves of response were obtained from the real system in the laboratory and were compared to both responses, giving a satisfactory and very similar result. These results will functionate as a basis for further studies in the areas of speed control (orcharge controller) and system stability, among others, in the field ofMHPs for small isolated systems.
