Prototype of Automatic Frequncy Control in Microhydro Power Plant with Dummy Load Based on Arduino Uno and Labview

Micro hydro power plants are small-scale that use hydropower as their driving force. Hydropower can come from irrigation channels, rivers or natural waterfalls, which used by utilizing the waterfall height (head) and amount of water discharge. The main components this plant turbine generator. load on micro generator will affect value voltage frequency generated. This research attempts to make a with automatic control using dummy in form inductance is obtained variac. output current be read Arduino center ZMPT101B AC sensor ACS712 sensor. reading travel time 1(one)full wave. also equipped variable monitoring system for Labview. From observations data, it was revealed an controller close mesh frequency, namely 51 - 52 Hz.
