Electricity performance is characterized by the stability of voltage and frequency of the generator. To maintain the electricity performance, the generator speed is held stable at its nominal speed using a governor system. Electric governor system commonly used on hydro power plant. However in this study the electric governor system was developed for microhydro power plant. The Electric governor system was developed using NI myRIO® 1900 microcontroller device to accelerate the response due to load variations, and can be functioned as monitoring equipment.. The microcontroller device obtained input signal from generator speed sensor, voltage and ampere meter, and the position of the wicket gate. Afterwards, the microcontroller regulate the required wicket gate opening and the generator speed can be held stable. The governor system developed for 3000 rpm, 220 V, and 1 kW generator. The data obtained from this study shown that the developed electrical governor system has a 20-second response time to return the generator's speed to its nominal speed with load variations given to the generator is every 20% (200W). Operational shutdown system by the governor system due to the instability of the generator speed takes 24 s.
