摘要
耦合地线是提高输电线路耐雷水平的重要措施。为研究其提高线路耐雷水平效果,利用EMTP软件建立了耦合地线的仿真模型。通过仿真得到架设单耦合地线以及双耦合地线后对雷电流的分流作用,以及架设前和架设后的耐雷水平提高的程度,并提出了相应的改造措施。
Coupling ground wire is an important measure to improve the lightning withstand level of transmission lines. In order to study the effect to improve the lightning impulse withstand level, set up the simulation model of coupling ground wire by using EMTP software. Get the shunting effect of lightning current erecting coupling groundwire by simulation, and the degree of the lightning withstand level before and after the erection of the erection of improvement, and puts forward the corresponding reforming measures.
