This is about a system of quantity and quality management. Its aim is to provide
remote handling, remote control and the leakage tracing of a water supply network.
In fact, it consists of:
- PLC (Programmable Logic controllers), that control the operation of valves, pumps
and dosing pumps of potable water chlorination. To these, measurement instruments
of pressure, tank and well level, water flow and supply, chlorine consistency,
water dimness are connected.
- Computers, where the PLC data is transferred and displayed, and after its processing,
it is registered in historic archives and remote control is performed.The remote
control and the remote handling of the water supply network in real time are done,
through special software, called SCADA (Supervisory Control and Data Acquisition),
which is installed in the computers.
- Communication system, which connects the PLC with the computers wirelessly (with
radio-modems) or wired ( through modems).
- Remote handling includes the pump starting and pause, the handling of electric
valve of the water supply network and the operation of dosing pumps for the potable
water chlorination.
Remote control realizes the parameters’ registration of the water distribution
network.
Such as: pressures, water and supplies flows, tanks’ and wells’ levels, remaining
chlorine and water dimness.
In addition, damages and alterations in the system’s elements status (e.g. pump
and electric valve damage, etc) are monitored and registered providing this way
detailed data for the type and place of the damage, facilitating the rapid intervention
of the maintenance personnel for the damage restoration.
Finally, the electric parameters’ control of the network’s elements is possible
and it enables the appropriate intervention for energy saving.
For any leaks of the network, there is sample taking from some of its values
from the special local stations (Local Leaks Station, LLS) and a mathematical
model is used that enables the algorithms’ development, which in their turn trace
the leaks and depict them in the system’s SCADA.
With slight variations, the model of water resources management can be applied
to irrigation networks, city drainage as well as installations of urban sewage
plant.
