BASF-electricity grid with connection to the transportgrid of Amprion GmbH and possibility of island operationSince more than two decades, BASF AG has operated and monitored their electrical network and various pipe networks with PSI control systems at their main location in Ludwigsha-fen.

BASF AG, founded in 1865, is even today one of the largest chemical groups in the world based on revenue and market capitalisation. The BASF location in Ludwigshafen is the largest continuous chemical site in the world.

For supplying the factory with electrical energy, a comprehen-sive electricity network has been constructed with voltage levels from 220 kV to 6 kV. This network is coupled with

Amprion‘s 220 kV transmission network. The supply of critical production units in stand-alone mode in case of faults in the Amprion network is guaranteed with the company’s own generation units.

These units also generate steam needed for production purpo-ses in multiple steam levels.

The first contract for an integrated control system for operating this network was awarded to Siemens with PSI as a subcont-ractor for the system conception and realisation of the control system software including stand-alone operation. The control system was equipped with the most powerful process computers

of that time to allow for realtime operations.

The appearance of workstations with the UNIX operating system also caused a technology change for large control sys-tems. The savings in maintenance costs for process computers alone refinanced the modernisation of the control system with workstations as new hardware base in a very short period of time.

The realisation of this control system renewal was entrusted to PSI.

In order to fulfil continuously increasing requirements on network operations and planning, PSI has jointly implemented

the IMENDO X-PORT interface solution with Austrian IMENDO GmbH for BASF.

With assistance from IMENDO X-PORT, all relevant network information from the BASF equipment databases is sent to the PSI control system, verified and prepared for the NEPLAN network planning tool.

In doing so, network planning always works with a current and verified realtime database in NEPLAN without the great effort and expense of manual data entry.
