ASKİ constantly monitors the facilities it uses (pump
stations, water tanks, treatment facilities, water distribution network and
facilities required for auxiliary works) in order to fulfill its duty of
supplying safe water to the city.
In addition, the maintenance of these facilities is also
important for the healthy running of the business. The facility and the network
should be monitored for 24 hours, as the damages caused by the malfunctions
that may occur can be very large. In recent years, a special system has been
developed, which is widely used in many industrial and service sectors where facilities
and stations are scattered and called SCADA system in short. S.C.A.D.A. It is
the abbreviation of the English words "Supervisory Control And Data
Acquisition".
Stations in ASKI SCADA System; It is classified in three
different ways as pump station, water tank and measurement point. There are 60
pump stations, 108 water tanks and 13 measurement points in the system. The
system basically consists of two main parts:
1. Control Center
2. Outside Stations
The Control Center is equipped with highly sophisticated
computers and supported by special computer software. In the center, which
provides uninterrupted service for 24 hours according to the shift system, 3
operators are constantly at the computer and receive and evaluate the data from
external stations. The Control Center is located in a building in the garden of
ASKI General Directorate.
Electronic devices that make the necessary measurements for
the operation of the network have been installed at the external stations (Pump
Stations, Water Tanks, Measurement Points and Treatment Plants). These devices
transmit their measurements to the ASKI Control Center via the communication
system (ASKI SCADA System provides communication between the control center and
external stations via its own radio system).
The information sent to the Control Center is evaluated by
the operators here and necessary actions are taken. These equipment are
controlled by sending commands (closing, opening and starting, stopping) from
the computers in the control center to the valves and pumps. All of the
measurements made at the external stations are monitored instantly in the
Control Center. In addition, the instantaneous values are recorded on computers
historically and it is possible to reach these values whenever desired.
