The AQUIS model is fed with live information from the SCADA system as
well as forecast information about weather conditions. This enables the
model to predict future consumption even during periods of quickly
changing or extreme weather conditions.
Different variables, such as supply pressure, age of the water, amount of chemicals in the water or flow can be displayed. Effects of interventions, such as opening or closing of valves can be assessed by simulations, which reveal disturbances in consumer supply.
What are the Benefits of AQUIS Operation
AQUIS Operation gives the operator a number of immediate benefits in
terms of better overview and improved operation of the network, both
from a technical viewpoint as an economic.
Improved Network Overview
AQUIS
Operation gives the operator full overview of all aspects of his
distribution network. This will provide operational understanding of
bottlenecks and potential performance of the network.
AQUIS Operation displays the data, such as age or pressure, with color coding all over the network, enabling the user to learn how the network is functioning at any given time.
The information can be made available to the call center. Error conditions or temporary problems will be evident. The call center can click on any node in the network to see measurements such as the water pressure at the specific location. Alarm setpoints for all parameters can be preconfigured.
The model has an accuracy of around 1%, which means that the model can, in most places, substitute the need for costly instrumentation – here alone the pay-back of AQUIS Operation is secured several times.
Prediction of Demand
AQUIS
Operation is fully integrated with SCADA and can be prepared to send an
alarm to the SCADA system if error conditions in the network are predicted. The
AQUIS system will constantly predict the demand of your network, which
is based on history and on the current and future weather situation.
By
a click of the mouse the operator can simulate the closing of a valve.
AQUIS will run prediction and return an alarm if one of the
pre-configured set-points is exceeded. The operator will therefore
quickly and easily be able to advise the staff in the field if it is
safe to close a specific valve. Other related problems can be seen and
avoided with intervention simulation.
Embedded Leakage Management System
The system facilitates an easier and quicker identification of
leakages, theft or unidentified customers. Consequently the non-revenue
water issue can also be addressed and appropriate action taken.
