Sažetak
Lightning location systems (LLS) provide data on lightning activity such as
lightning type, GPS location, exact time of the lightning stroke, lightning current
amplitude, measurement error, etc. The proper application of LLS data using
customized software support can be a powerful decision-making tool in the control,
maintenance and development of power systems. The utilization of lightning data in
power systems requires a customized software support with specific functionalities.
Software functionalities include real time lightning activity visualization with
alarm function; analysis, reports and historical lightning activity visualization;
spatial correlation between lightning data and alarm zones around geographically
represented power system’s objects (power lines, power facilities, etc.); calculation of
lightning statistics; generation of wide area lightning density maps, generation of
high resolution lightning density maps inspecting alarm zones around the power
lines; real time correlation between lightning activity and the power system
protection equipment (distant protection relays), gathered through the SCADA
system. In this paper, emphasis will be given to the application in correlation
between faults and outages in the power network and lightning strokes. Today,
