Delft-FEWS for Run-of-River Power Plants
Delft-FEWS continuously imports recorded water levels, discharges
and operating conditions in the barrages, at the weirs and
turbines and evaluates this information with the calculated forecast
data.
With the help of RTC tools, 2 the discharge from the reservoirs
can be optimized using the weir height as a control variable.
Specified target values regarding energy generation, flood protection
and water ecology are thus met.
When a flood wave is expected, the operator can provide retention
space in good time by lowering the reservoir water level in
advance.
The re-storage can be initiated as quickly as possible to minimize
the impact of the flood on the safety of the hydropower supply.
Delft-FEWS supports the operation of
Run-of-River Power Plants.
Delft-FEWS for Storage Power Plants
Delft-FEWS is scalable from simple to highly complex systems representing
complex topologies with several hydropower plants and
interconnected reservoirs.
The forecasting system provides concrete inflow forecasts based on
hydrological calculations and thus supports the management of the
reservoirs. RTC tools 2 can be used to optimize control processes.
Based on measured reservoir levels, power generation schedules
and forecast data, a predicted balance of levels is determined. In
this way, trends can be identified at an early stage, especially for
storage facilities managed during the year.
Storage Power Plants can be run more
efficiently by the forecasting system
Delft-FEWS.
With the integrated decision support module, users can simulate
and visualize processes and control them in the forecast both rulebased
and interactively.
Delft-FEWS is an operational model-based system
for flood and runoff forecasting. It is developed
by Deltares, The Netherlands and used worldwide.
It is free of licence fees.
Hydrotec configures forecasting systems based
on Delft-FEWS according to customer specifications
and provides support and maintenance.
