PSI Receives Order from 50Hertz Transmission
Grid calculations for the operation of the 380/220 kilovolt transmission network
Berlin, 28 April 2011 – PSI AG has been contracted by the 50Hertz Transmission GmbH with the delivery of grid calculation functions for the 380/220 kilovolt transmission network in northern and eastern Germany. On the basis of the PSIcontrol control system, PSI will provide functions for the support of the network operations with the dramatically increasing decentralised input of renewable energies. These functions will initially be coupled through interfaces with the control system which 50Hertz has used to date.
50Hertz Transmission is responsible for the operation, maintenance, planning, and expansion of the 380/220 kilovolt transmission grid throughout the northern and eastern part of Germany. The grid covers an area of 109,000 km2 and is about 9,750 km long. It secures the network integration of approximately half of all the wind-generated power in Germany.
The grid calculation and optimisation functions used by 50Hertz in the future have been successfully employed by other larger operators of transmission grids for some time. With 50Hertz Transmission, PSI has won an important new customer and therefore further expanded its strong position in the German energy market.
PSI AG develops and integrates complete solutions, on the basis of its own software products, for the management of energy networks (electricity, gas, oil, heat, water), cross-company production management (metals, automotive, mechanical and plant engineering, mining, logistics) and infrastructure management for transport and safety. PSI was founded in 1969 and employs 1,400 persons in the group.
