Abstract
The generator unit is driven by a small Pelton turbine (10) having a plurality of injectors (11) each comprised of a single tubular part connected to a ring-shaped distribution chamber. The turbine wheel drives a multiphase synchronous generator (20) having permanent magnets. The alternating voltages produced by the generator are rectified in order to obtain a direct voltage of 24 V. The water flow rate is regulated at the input of the turbine by means of a regulation valve (13) controlled by an electronic regulation unit (23), to automatically control the power of the generator unit as a function of the output voltage variations. Said portable generator unit, which is extremely simple and reliable may be provisionally or permanently used wherever a pressure water connection is available.
