Determining of fault location with Hilbert - Huang transformation on XLPE cables between land and offshore substations

Using of mathematical transformations and digital signal processing (DSP) methods of recorded voltage and currents in power systems in order to extract important informations about physical processes is already known. Higher measuring resolutions and massive introduction of PMU devices in the power systems allows appliance of DSP - based fault location methods in complex power networks. High availability of power systems is required in the modern societies. Fast fault location algorithms and consequent fast repairing of faults is necessary condition for high availability of power networks. Here represented numerical procedure for fault location is testing of method already introduced in scientific papers on complex configuration of power network consists of XLPE underground submarine and land cables between land and offshore substation connecting large wind park with main power system.
