Abstract: The invention is directed toward an electrical power control system (1) in an electrical power system, having: a power control unit (2) for setting electric state variables and/or parameters in a current conductor, to be controlled, of the electrical power system, having: means (3) for detecting electric characteristic values (u1) of the current conductor; a function processor for applying a control function (F1(u1)) from a mathematical set of control functions to the electric characteristic values, and for determining controlled variables (y) for achieving the parameters; and coordination means for determining a control function (F1(u1)) from the set of control functions with the aid of operating states of the electrical power system. This system renders it possible to achieve a predictive tuned control of the electrical power control system which can also stabilize unusual operating states of the electrical power system.

Abstract: The method according to the invention is based on a configuration model of a part of an electrical power distribution network, describing a totality of possible configurations of appliances. The configuration model is used to systematically produce (2) all the possible configurations which satisfy a predetermined set of functional requirements, in which case each possible configuration may have at least one associated characteristic value, and a solution configuration is defined which optimizes this characteristic value. It is thus possible to produce an optimum configuration automatically, without any need for expert knowledge about the appliances used in the configuration. In one preferred embodiment of the invention, a simulation model for simulation of a technical response of the solution configuration is produced automatically (3).

Abstract: A design for a high or medium voltage power transmission network is created automatically. The network comprises a plurality of subsystems that are classifiable as switchgear, transformers, transmission lines, or network controllers such as compensators, where each subsystem comprises a plurality of components, where components exist in different embodiments having different technical and economical characteristics, and where the design comprises, for each subsystem, a selection of components such that the subsystem satisfies given technical and financial criteria.

Abstract: In a method, computer program and data processing system for simulating an electrical power transmission network, a representation of the transmission network represents a power transmission section of the network linking a pair of buses, an internal network section (1) connected to said pair of buses and an external network section (2) comprising at least one adjoining network that is connected to the internal network section (1). A composite network section that comprises both the external and the internal network section is represented by a Ward equivalent circuit (6).
