Smooth execution of AlzChem's medium-voltage substation upgrade project

2017-01-24 - ABB has delivered a high-performing medium-voltage solution with ZX2 switchgear and Relion protection relays to AlzChem's chemical plant in Trostberg, Germany.

At the facility in Trostberg, AlzChem focuses on the production of nitrogen-carbon-nitrogen bond (NCN) chemistry products. At the site, AlzChem was facing problems with aging equipment, which was causing high maintenance costs and malfunction problems. The customer identified the need for a cost-effective upgrade solution to improve the reliability of the electric power system, and set out to find a reliable business partner, who on top of providing technically well-suited products, also had the knowledge to fully understand the requirements and the ability to manage the project successfully within the limited time frame.

ABB delivered a high-performing solution based on the compact and powerful protection and control functionality available when combining the leading-edge Relion® 630 series protection relays and the primary double busbar switchgear ZX2, and using the
remote terminal unit RTU560 for station control. The high performance is achieved thanks to the compatibility and flexibility of all the devices used in this solution. The solution is built on IEC 61850 communication, which is used for both horizontal (Generic Object Oriented Substation Events; GOOSE) and vertical communication. The flexibility of the protection relays made it easy to engineer and commission the overall protection scheme. To achieve high reliability, the solution employs a star architecture instead of a traditional ring architecture.

In this turnkey delivery, ABB installed and commissioned all products on site. The overall time needed to engineer and commission this project was significantly reduced as a result of the close cooperation between the partners involved. The combination of project management and engineering expertise with ABB’s high quality products resulted in a smooth and on-time project delivery.
