The system controls and monitors gas distribution to almost 80% of the Czech
citizens. The system consists of gas delivery stations, step-down stations and other
technological equipment which are located all around the Czech Republic.
New dispatch center
The members of the RWE group had been looking for a new dispatch center since
2007. They had prepared a project to unify all levels of control and monitoring of
gas distribution in the Czech Republic. Finally, the new dispatch centers in Brno and
Usti nad Labem were put in operation in the middle of 2010.
The volume of the dispatch center solution is unique, also in an all-European point
of view. More than 2,000 connected nodes, more than 150,000 I/O variables, 13
operator workplaces and the possibility to monitor via the internet.
The whole system is fully redundant. One system is installed in Brno and a second
one in Usti nad Labem (distance between the cities is approx. 300 km). Current
and historical data is synchronized in real-time between the centers. In case of
shutdown of one center, the second center automatically takes over all control
Due to high requirements for availability, fault tolerant systems are used on server
levels, LAN equipment and other hardware.
400,000 objects in one system
The project uses an IGSS multiuser system with 13 operator workplaces and
The application is split into 5 areas:
- Gas high pressure distribution of RWE GasNet and VČP Net
- Local gas distribution net of RWE GasNet and VČP Net
- Gas high pressure distribution of JMP Net
- Gas high pressure distribution of SMP Net
- Local gas distribution net of JMP Net and SMP Net
For data collection, a dualized system consisting of two servers, is used. The frst
server is located in Brno and the second server in Usti nad Labem. Both servers are
running in a cluster server and have their own SQL server.
Ethernet communication is used (WAN and GPRS) and the IEC 870-5-104 protocol.
The process control system uses UniNOD Compact stations, CP321, Adam 5001, DIO
3000, ZAT, WAGO and many others.
Overview and fexibility
The availability of the entire distribution system was rapidly increased.
Furthermore, the overview of the gas distribution was improved and data could be
shared by all users. The system is more fexible, open and extendable in the future.
Prepared for the future
The installed system has been prepared for future connection to all gas distribution
equipment. A new project is already in preparation which will add another 2,000
