METHOD FOR PLANNING AN ELECTRICAL POWER TRANSMISSION NETWORK, PLANNING ARRANGEMENT AND COMPUTER PROGRAM PRODUCT

A method for planning an electrical power transmission network using a planning arrangement includes providing a first input dataset, and converting the first input dataset into graphical representation using a conversion device. The graphical representation contains topology information for interconnection of equipment items and data communication information and parameterization information for equipment items. Different types of equipment are distinguished by a first identifier, electrical connections are distinguished by a second identifier and data communication links are distinguished by a third identifier. Multiply recurring patterns in the graphical representation are identified by a pattern recognition device. A respective frequency of patterns is determined by the pattern recognition device. All patterns having a frequency exceeding a predetermined threshold are marked as candidate samples by the pattern recognition device. Typical configurations are selected from the candidate patterns using a selection criterion. A planning arrangement and a computer program product are also provided.
