METHOD FOR LOCATING A FAULT IN A POWER GRID ON THE BASIS OF DISTRIBUTED VOLTAGE MEASUREMENTS

摘要

a method of localization of defect on an electrical network power source uses a form of a triangular voltage measurements at least three different locations on the network, with at least one of the upstream of the defect sites compared with the source. the voltage corresponding to phase voltages are measured in the absence synchronises temporally.drivers involved in the network are determined as a function of defect characteristics of voltage and current of a phase failure resulting in a voltage drop is measured by a location of an initial value of the voltage is measured.the position of the flaw is evaluated in a connection between a network and a difference of two voltages measured at measurement locations and an impedance between one of two sampling locations and the point under consideration, depending on the driver is informed of it. default.
