Conference Paper: Estimation of Pulse Function Parameters for Approximating Measured Lightning Currents Using the Marquardt LeastSquares Method
[Show abstract] [Hide abstract]
ABSTRACT: The Marquardt leastsquares method is applied in this paper for estimation of the Pulse function’s nonlinear parameters in order to approximate measured lightning currents. Such procedure is generalized so it could be used for other pulse functions representing lightning current waveshapes. The obtained results show that this method provides good results for the IEC 623051 standard lightning current waveshapes of the first and subsequent return stroke currents, and also for some measured fast and slowdecaying current waveshapes.EMC Europe 2014, Sweden; 09/2014  [Show abstract] [Hide abstract]
ABSTRACT: This review paper, prepared for this second special issue on lightning of the IEEE Transactions on Electromagnetic Compatibility, summarizes major publications on lightning and lightning protection since the first special issue published in November 1998, i.e., during the last decade. The review is organized in the following five sections: lightning dischargeobservations, lightning dischargemodeling, lightning occurrence characteristics/lightning locating systems, lightning electromagnetic pulse and lightninginduced effects, and protection against lightninginduced effects.IEEE Transactions on Electromagnetic Compatibility 09/2009; · 1.33 Impact Factor  [Show abstract] [Hide abstract]
ABSTRACT: This paper presents a novel, easy to use, engineering method for determining the transient electromotive force (EMF) induced in lowvoltage (LV) cables, connecting the wind turbine with a nearby transformer, in the event of direct lightning strike into the top of the wind turbine tower. Proposed method is based on the application of the travelling wave analysis onto the system consisted of wind turbine tower, earthing system of wind turbine, earthing system of nearby transformer station and LV cables connecting the wind turbine with associated transformer. Hence, this design gives rise to a complex, mutually connected, earthing system. Direct lightning strike to the wind turbine initiates a travelling wave process in the system consisted of lightning channel, wind turbine tower and earthing system of the wind turbine. Due to the transient nature of the observed phenomenon, current and voltage states at the earthing system as well as in the associated lowvoltage cables are formed through the propagation and reflection of the accompanying travelling waves. Transient EMF induced in LV cables could endanger cable main insulation and insulation of the associated transformer LV winding. Developed theory is subsequently applied on the concrete wind turbine example.Electric Power Systems Research. 01/2010;
