Overview:
Funktion:
Load- or Flow- controller ensure that the power output does not exceed the power demand (e.g. 230V, 50 Hz).
If flow of water in a MHP-station is constant the energy output of a turbine/generator is constant as well. Power demand is usually fluctuating over the time (e.g. day/night). If supply is higher than demand, excess energy is diverted/dumped or the flow is reduced. In case of more power demand than supply the controler cuts of the of demand line. Load controller are placed between generator output and the consumer line.
