Short-Term Electromagnetic Interference on a Buried Gas Pipeline Caused by Critical Fault Events of a Wind Park: A Realistic Case Study

Abstract

Short-term Electromagnetic Interference (EMI) pertains to the total result produced by the occurrence of intermittent, inductive and conductive couplings on a buried pipeline system. For example, this type of EMI takes place when considering the fault conditions of a single a.c. power line, acting in the nearby vicinity of a pipeline system. In the context of this paper, the effect of the short-term EMI is unfolded through a real case study. This case study involves a 20.7 MW Wind Park with extended underground power cable connections, which are laid nearby a high-pressure gas pipeline system. In particular, the impact of critical fault events, associated with the Wind Park’s power cables, on the pipeline system is comprehensively assessed. The assessment is achieved by the concurrent use of two powerful software tools that are respectively eligible for the accurate short-circuit analysis of the electrical circuit of the Wind Park and for EMI evaluation on the pipeline.
