System for analysis and integrated simulation of faults in an electrical power system.

摘要

System for analysis and integrated simulation of faults in an electrical power system, in which are used: a) a set of faults sources, with pre-fault and post-fault voltage and current values; b) a database of the lines of the electrical system; c) a database of the protections; d) an intelligent unit programmed with data on the protections modelled according to the following stages: - assimilation to a phase comparator with two inputs: operating signal Sop and polarisation signal Spol - obtaining of the equivalent cosine comparator - obtaining of an analytical model of the comparator, being based on the connection between networks with a sequence which are deduced from the application of the method of symmetric components and of the superposition theorem, breaking the network down into a network prior to the fault P and an auxiliary network Q.
