The using of Electronic Load Controller (ELC) to replace governor in MHP

By Achmad Hasan

The using of Electronic Load Controller (ELC) to replace governor in Microhydro Power Plant (MHP) can hopefully manage the enormous changing of load by giving a quick system response and lower price than governor. Because of providing power for electricity require high cost and the geographic condition of Indonesia also the unbalance spread of load, so the MHP is the most economic energy resource. MHP is the right plant for providing energy especially for remote area with a low load crowd and far from PLN (Indonesian state electricity company) network.

Electronic Load Controller For Microhydro System ( ELC )

This article intended to help people, by presenting a simple, low cost ELC that can be built from easily available components.

Use of ELC in microhydro system can help manage the load change with fast response. it's very similiar to the old mechanical speed governor that acts on a mechanical brake, only that an ELC uses electrical braking : dump loads into which excess electric power can be put. Click here
