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). That is, the entirety of the network, with the exception of a transmission section, is represented by a basic or extended Ward equivalent circuit. The data required to represent the network is drastically reduced. Planning procedures using the network model are simplified and accelerated.
