Improving Lightning Location System and Advance Control, Maintenance and Planning of Transmission Power System using Lightning Location System Data
Complete lightning data were collected using lightning locating system (LLS) in Croatia by the Croatian transmission system operator (TSO). The LLS correlation system runs as a part of the National control center’s utility function, collecting lightning data and correlating with network data in real-time. The real-time lightning correlator function relies upon SCADA to acquire network faults, circuit breaker (CB) operations and relay protection data. Geographic information system (GIS) functionality was integrated into the LLS correlation system in order to make the spatial correlation between lightning strokes and network events. Lightning data are available since 2009 and lightning correlated faults data since 2013, providing full eight and four years, respectively, of precise and comprehensive data inputs from LLS, SCADA and GIS systems. Network planning processes are improved by using statistical and spatial analyses results of lightning correlated data as additional inputs for transmission line reconstruction, modernization and designs of new transmission lines. Lightning statistics for the Croatian transmission network will be presented in this paper to prove a context for the lightning related statistics of the observed transmission network. Statistical analyses on lightning correlated data are conducted taking into account 339 transmission lines of 110, 220 and 400 kV, with total length of 8 458 km. Latest improvements of the system will be presented as well as an example of spatial analyses of transmission lines containing critical segments.
