This paper presents the control and monitoring system of a small hydropower plant (SHP). The control rules of the parameters in that type of objects, their practical realization by a dedicated control system and exemplary operation were described. In the second part the way of algorithm implementation using a modern hardware was presented. The control algorithm implementation from the software point of view was also shown. The paper contains the measurements from the real control and monitoring system of SHP. This SHP contains two permanent magnet (PM) generators of 75 kW electrical power each, which can work at a variable speed.
