The proposal “Microcontroller based Electronics Load Controller for micro-hydro system” presents design of a microcontroller based electronic load controller (ELC) for synchronous generator intended for a stand- alone micro hydro power generation. An Electronic Load Controller (ELC) is an electronic unit which keeps the speed of synchronous generator constant at varying load conditions. The generator is driven in constant speed with constant power output. A dump load is connected across the generator terminals to dump the excess power generated. When the consumer load changes frequency of generated voltage also changes. The frequency is sensed and compared with the reference frequency and error so obtained is utilized to control power consumed by dump load so that generator always operates at its full rating, resulting in constant speed.
