Connecting the outstations (power / transformers) over existing copper infrastructure and via public networks (mobile phone network / DSL)

BASF AG

Today, the globally active group with headquarters in Ludwigshafen has more than 2,000 buildings and an area of more than 10 km², making it the largest contiguous chemical complex in the world. A lot of energy is needed for chemical production which is generated particularly efficiently by three factory-owned power plants. Thousands of kilometres of cables, most of which are laid underground, distribute the electricity at the site. Numerous transformers distributed throughout the factory supply the voltage required by the various operations.


Aim

Connecting the outstations (power / transformers) over existing copper infrastructure and via public networks (mobile phone network / DSL)


Situation

Ethernet modems are deployed to transmit data over existing copper cables, in order to connect up the outstations. Thus, electronic meter and control station data are transmitted to the control centre via a dedicated SHDSL line. Up to the present day, the aim has been to use a telecontrol system to connect up the devices which guarantees communication paths without failures in compliance with current laws, regulations and standards, in order that industrial accidents can be prevented.


Solution

The SHDTU Ethernet modems and ISD fibre optic switches are suitable for DIN top-hat rail mounting, to transfer data from the outstations to the control centre. A rack solution is deployed in the control room, where all data converges.
