Study of Lightning Surge Over-voltage at Substation
With ith development of transmission and distribution engineering project,project demonstration demonstration,experiment and research of substation are done in-depth.The simulation of protection of lightning intruding surge is the important content in 220KV substation,which is research in-depth by many electric power experiment research institutes and power design institutes.Aimed the new equipment that is AIS （ Air Insulated Switchgear Switchgear） in some substation,the model should be improved.In the text,structure and test parameters of AIS which are afforded by manufacturer are analyzed.Calculating method of thunder over voltage is optimized,and the selection of the main initial condition of lightning intruding surge is researched in-indepth,depth,the model of substation devices are analyzed.Aimed several operations of an outgoing loop and transformer in the 220KV AIS substation,use the International common Electromagnetic transient program(EMTP-ATP) to ca callllculate culate the amplitude value of thunder over-voltage in substation equipment.The he results are used to analysis the effect of lightning prevention.In the passage,some factors which influence the amplitude value of the lightning intruding surge are considered considered,at the same time,the measures of lightning prevention are introduced.
