A New Return Stroke Model Based on State-Space Equations

摘要：

This paper presents the basic ideas of a new lightning return stroke model that describes the evolution of return current by means of state-space variables. The channel is reproduced by a sequence of distributed circuit elements that are allowed to vary in height and time. The model allows substituting the traditional injection of current into the channel base by the formation of the return current from the dropping of charges deposited along the corona sheath into the channel core. Though only preliminary results have been obtained, this more realistic representation seems to have potential to reproduce the typical features of lightning currents measured at the channel base.
