Simulation of an electrical power transmission network
First Claim
1. A method for simulating an electrical power transmission network, where a computer representation of the 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, characterised in that the method comprises the steps of determining parameters of a Ward equivalent circuit (6) representing a composite network section that comprises both the external (2) and the internal network section (1), analysing a behaviour of the Ward equivalent circuit (6) connected to a representation of the power transmission section.

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.

10. A computer program for simulating an electrical power transmission network, where the computer program maintains a representation of the network, and said representation represents a power transmission section of the network linking a pair of buses, an internal network section connected to said pair of buses and an external network section comprising at least one adjoining network that is connected to the internal network section,
characterised in that a composite network section that comprises both the external and the internal network section is represented by a Ward equivalent circuit.
