Dump load controller

A dump load controller keeps a small isolated system in balance by diverting surplus power into a resistive load, usually water or air heaters. In micro hydro systems it holds frequency constant by keeping total generator load fixed, and in small wind or battery systems it protects the battery from overcharge by dumping excess energy.

Drawing use: SLD / Schematic
Application: Microgrid systems
Reference family: IEC / IEEE / ANSI

A distinction that matters

A dump load controller diverts surplus energy continuously; a load bank is a test load used temporarily.

Hydro turbine generator

A hydro turbine generator converts water flow and head into electrical power through a Pelton, Francis, Kaplan or crossflow turbine driving a synchronous or induction generator. In microgrids, small hydro is valuable because it is dispatchable within the limits of the water available and supplies real rotating inertia.

Application: Microgrid systems
Reference family: IEC / IEEE / ANSI

A distinction that matters

A hydro unit is driven by water; its control differs from a thermal genset because load changes are limited by penstock dynamics.
