| | + | ensure that the power output does not exceed the power demand (e.g. 230V, 50 |
| | + | Hz). </span> |
| | + | |
| | + | <span lang="DE" style="font-size: 11pt; font-family: Tahoma; color: black;">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). </span><span lang="DE" style="font-size: 11pt; font-family: Tahoma; color: black;">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. </span> <span lang="DE" style="font-size: 11pt; font-family: Tahoma; color: black;">Load controller are placed |
