Summary
This Technical Brochure (TB) provides comprehensive guidance for the modelling and simulation of Very-Fast Transients (VFTs) in Gas-Insulated Substation (GIS). It develops practical modelling guidelines for electromagnetic transient (EMT) -type and EMT- finite element method (FEM) interfaced simulation approaches, covering major GIS components and high frequency electromagnetic phenomena. Eleven benchmark cases are established to validate and compare EMT, FEM and finite-difference time-domain (FDTD) simulation methods against field measurements. The TB also investigates VFT-induced electromagnetic interference (EMI) in secondary control, protection and instrumentation systems and proposes electromagnetic compatibility (EMC) requirements for consideration in future IEC standard revisions. The results provide utilities, manufacturers, researchers and standardization bodies with a common technical framework for accurate, consistent and reliable assessment of VFTs in modern GIS.
