Control Systems for Regional Distribution Networks

With PSIcontrol, PSI provides a software solution with numerous high value applications which ensure secure operation of high, medium, and low voltage networks. The smart grid functions are an important component which provide network operators with the necessary support for secure management of electrical networks.

Examples are:

  • Overhead line monitoring,
  • Generation management for decentralized energy infeeds,
  • Congestion management,
  • Network applications, also for medium voltage,
  • Load estimation, voltage and reactive power control as well as
  • Disconnector optimization.

PSIcommand supports energy companies effectively in both technical service and operations management. The integration of information relevant to operations, the modeling of the operational processes, and the application of innovative technologies offer efficiency potential and sustained quality improvement in the relevant processes

  • Fault clearance management
  • Maintenance management and
  • Crisis Management.

Multi-Utility Networks

Multi-Utility Control Center Technology

PSIcontrol-Multi-Net has been developed for managing different supply networks in the same control system.

The concentration of the control technology provides significant benefits regarding the initial investment as well as the operating cost.

PSIcontrol-Multi-Net enables management of several logical control systems within the same physical control system. The Multi-Net software system uses separate data model environments. Customers can now choose between a multi-utility operating mode or operating all networks separately.

PSIcommand is particularly well suited as operation management system for multi-utility systems. In these systems, usually many distribution locations in close proximity have to be located. The on-site crews can locate the fault locations only based on precise navigation which is important for efficient fault clearing. In addition, PSIcommand supports cross-utility work by integrated service crews.

Railway Electricity Networks

Control Systems for Managing Railway Electricity Networks

Railway companies operate their own electricity networks to supply their railway system with electricity. The requirements for monitoring and control (transmission and catenary level) are on one similart to those of regional network operators. On the other hand, railway-specific constraints must be considered and the corresponding functions be implemented.

Examples of this are:

  • Special switching programs for the catenary level,
  • Forecast functions for planned switching operations,
  • Tunnel monitoring,
  • Simulation of moving trains,
  • Network control (transmission networks).

After supplying all central control centers for catenary electricity and a central support tool (PSIcommand) for Deutsche Bahn, several other major railway companies have awarded high value orders for railway electricity control systems to PSI.

Industrial Networks

Control Technology for Industrial Networks

Due to the energy turnaround and the Renewable Energy Act, industrial customers are showing increasing interest in energy management functions.

PSI offers control system functions which enable cost-efficient use of energy. The additional module "virtual powerplant" allows energy-intensive plants to pool and participate in the energy control market. In cooperation with production planning, both positive and negative tertiary power can now also be marketed.
