| Abstract: | In order to strengthen oil line lightning protection,the paper carries out the simulation and calculation of Dagang Oilfield transmission and distribution lines using electromagnetic transient calculation program（ATP-EMTP）,establishes a model for 110/35 kV quadruple circuit transmission line on same tower,and calculates the impulse grounding resistance of the grounding grid.Based on which the paper analyzes the effect of lightning arrester configuration mode on lightning withstand level.For analyzing the development of lightning induced overvoltage,the paper performs the numerical calculation and characteristics analysis on the induced overvoltage by means of Heidler lighting current model and Agrawal field-line coupling model.Finally,the paper gives the recommended installing density of the arrester. |
