In particular, a statistical procedure is proposed for the evaluation of the probability that a lightning flash detected by a Lightning Location System (LLS) could cause a fault and, therefore, relay interventions, generally associated with voltage dips. The proposed procedure is based on the coordinated use of the information provided by the LLS and the availability of an advanced simulation tool for the accurate simulation of lightninginduced voltages on complex power systems, namely the LIOV-EMTP code. The uncertainty levels of the stroke location and of the peak current estimations provided by the LLS are discussed and their influence on the lightning-fault correlation is analyzed. © Copyright KTH 2006.Electromagnetic transientsLightning induced overvoltagesLightning location systemsLIOV-EMTP codeMonte Carlo methodPower qualityCoordination reactionsCorrelation methodsElectric appliancesElectric load distributionElectric power distributionElectric power systemsElectric power transmission networksEstimationLightningLightning protectionLocal area networksPower transmissionProbabilityStatistical methodsStatisticsUncertainty analysisAccurate simulationApplied (CO)Complex powerDistribution systemsfault correlationinternational conferencesLightning flashesPeak currentsPower distribution system (PDS)power systemsProbabilistic methodssimulation toolsStatistical approachestransient voltagesVoltage dip (voltage sag)Probability distributionstext::conference output::conference proceedings::conference paper
