Gazprom - Russia
QNX 4 and OPC control system integration
Gazprom, the largest gas producing company in the world and
responsible for 8% of Russia's GDP, is using the Cascade DataHub and
Cascade Historian to monitor and control pumps, valves, consumption
control units, cranes, and other equipment along 23,000 kilometers
of pipeline spanning much of western Russia. The control system was
developed by the Federal State Unitary Enterprise and is called the
Unified Remote-Control Complex, or UNK TM. Software sales and support
were provided by SWD Software Ltd., a QNX and Cogent distributor in
St. Petersburg, Russia.
"The Cascade DataHub was the perfect tool for the job," said
Mr. Leonid Agafonov, Managing Director of SWD. "It is easy to use and
provides robust connectivity for the whole control system. Our
customer is very pleased with the project, particularly the
reliability of the software."
The system is an open, distributed-information control system with
modular hardware architecture running on the QNX 4 operating system.
A Cascade DataHub operates in each Control Room, and is connected to a
number of Remote Terminal Units (RTUs), which in turn are connected to
valves, pumps, and other hardware. The Cascade DataHub is also
connected to a SCADA system, various HMI modules, and the Cascade
Historian, which stores data to disk.
The system provides real-time operation, a multi-window graphical user
interface, data processing components, and archival disk storage of
data. Workstation devices and services, such as electrochemical
protection and operational service can be added or removed at any
time. There is also teletext communication between the Control Room
and the RTUs, through the Cascade DataHub.
The Unified Remote-Control Complex has successfully passed tests
administered by the Interdepartmental State Testing Commission and has
been recommended for use at OAO "Gazprom" units and facilities. The
system was developed by the Federal State Unitary Enterprise "FNPZ
Y.E.Sedakov NIIIS". It has a Measurement Instrumentation Approval
Certification #6398 and is listed as #18430-99 in the State
Measurement Instrumentation Register.
