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.

Drawing use: SLD
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.

Symbols

Three-phase synchronous generator

A three-phase synchronous generator supplies a documented AC source associated with its mechanical prime mover and excitation system. The electrical drawing identifies terminals, neutral and generator-control connections.

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

A distinction that matters

The electrical generator representation is different from the complete mechanical generator package envelope.
