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: The invention relates to a data processing device, a method and a computer programme for computer-aided substation tendering. Conventional substation tenders rely on by-hand selection of components representing not-preengineered, not-reusable substation parts. Such tenders are inaccurate and time-consuming. In this disclosure a module (2) represents a reusable preengineered substation part and is indexed according to an intuitive multiple-index categorisation system (12), has a standardized name (14) for designating all its related files and for encoding its function in an intuitively understandable, and has a module-descriptor (3) providing standardised information (4-10) to application routines for cost calculation (1a), technical data accumulation (1d), graphics accumulation (1b) and tender text accumulation (1c).

Abstract: The disclosed invention provides computer-implemented systems and methods for designing a power substation. The inventive method includes identifying functional requirements for the power substation and generating at least one substation design satisfying the functional requirements from a library of substation components. Additionally, functional preferences are identified and used to rank the generated substation designs.
