SCADA SYSTEM TO ENSURE SAFETY OF GAS-MINE
YEREVAN, APRIL 6, ARMENPRESS: Armenian-Russian HayrusGazArd
company, the sole supplier of Russian natural gas to Armenia, plans
to put into action Supervisory Control and Data Acquisition (SCADA)
satellite communication system in November. Deputy chief manager of
the company, Ashot Hovsepian, said the system’s installation will
cost some 800,000 euros.
He said gas transmission and distribution (T&D) companies depend
on the reliable operation of facilities over a widespread geographic
area. To maintain reliability of the T&D system, operators not only
require a regular and continuous flow of information as to how these
facilities are functioning, but they also must be able to contact
certain key facilities to make any operational changes needed to
maintain a properly balanced system.
Supervisory Control and Data Acquisition (SCADA) systems are
computer-based automated control systems that monitor and control the
transport of gas through pipelines. SCADA systems provide two basic
functions: real-time monitoring (sensing) and control at remote
sites.
The system is being installed by the German Siemens company, which
has chosen another German company, Plenexis, as a sub-contractor to
secure satellite communication.
