Berlin, 25 February 2014 – DB Energie GmbH has contracted PSI AG with the renewal of the Hamburg city rail electricity supply network control center and the integration in the Lehrte Central Switching Station (CSS) for the Integrated Network Control System North. The network control system of the Lehrte CSS will also be renewed in this context. The new system is based on the PSIcontrol standard platform, upon which rail-specific functions will also be implemented.
DB Energie has been controlling and monitoring the 16.7-Hz catenary network as well as the other systems with PSI network control technology for years. All 7 central switching stations work with the PSIcontrol control system. In addition, the fault clearance management and the technical reporting for the networks are supported by a support tool for control centres based on PSIcommand.
With the upgrade of the system in Lehrte to the distributed Control System North, a network control system is being established that is able to visualise and control the different and electrically separated networks. This will make it possible to integrate the network control for the direct current network of the Hamburg city rail into this system. The area controlled by the Lehrte CCS will stretch from the Danish border to northern Hessia.
The Control System North consists of two control centres with a total of about 10 working places. Both centres are responsible for their region, but can also take over the other area. The objectives of DB Energie are the general modernisation, increased effectiveness of the network control and the fulfilment of today’s higher IT security standards for process applications.
This then makes an important contribution to the reliable operation of the catenary networks. Along with the normal network control functions other wider-reaching rail-specific requirements will also be fulfilled. Amongst these are the forecasting functions for the online display of the impacts of planned, complex switchings, switch-dependent protective parameters, short-circuit analysis, support in the planning and processing of switching orders as well as a training system. These functions have already been implemented by other European rail-electricity network operators.
On the basis of its own software products, PSI AG develops and integrates complete solutions for energy management (gas, oil, electricity, heat, energy trading), production management (mining, metals, automotive, mechanical engineering, logistics) and infrastructure management for transport and safety. PSI was founded in 1969 and em-ploys 1,700 persons worldwide.
