Hamburg Wasser operates the central water treatment plant in the area Hamburg at the locations Köhlerbrandhöft and Dradenau. Two wind energy sites with 2500 kW each ensure the energy self-sufficient operation of the treatment plant.
With the commissioning of the 4 Mvar reactive current compensation delivered by us and the superordinate regulation in december 2012 one of the most modern plant with some technical peculiarities entert service after a testing phase of only one week, the peculiarities are:
- The enormous starting currents of the preassure pumps are compensated with a delay of typically 20ms on the 10 kV level with a thyristor controlled reactive current compensation.
- The slowly fluctuating reactive current requirements are distributed energetically optimal to the reactive current compensation and the reactive current ressources of both wind energy plants by the regulation.
- All operation parameters and readings are forwarded to the operation and guidance technology on the customer's side prepared accordingly.
