Realistic integrated grounding and electromagnetic interference analysis accounting for GIS, cables and transformers during normal and fault conditions

A network consisting of a substation including its buried and aboveground components and its overhead transmission lines is analyzed using rigorous electromagnetic fields based analysis. The entire system is modeled and its performance during steady-state normal conditions and fault conditions is examined and discussed. A long section of a buried pipeline is also parallel to the transmission lines. The substation model includes buried and aboveground components such as ground conductors, transformers, cables, Gas Insulated Switchgears (GIS), bus bars and shielding structures in order to account for their impact on the overall network performance during normal and faulted conditions.
