Guide for electromagnetic transient studies involving VSC converters

This Technical Brochure aims to provide comprehensive, documented, and validated descriptions of transients and associated ElectroMagnetic Transient (EMT) models and studies for VSC-HVDC converters. The objective is also to educate parties involved in VSC projects to explain what type of EMT studies shall be performed in the life cycle of VSC converters. It includes a large collection of typical transients which can occur in a VSC-HVDC converter station. It is intended for engineers performing and analysing dynamic performance studies, control and protection factory tests, and post fault records.

The scope of the Technical Brochure has been restricted to point-to-point VSC-HVDC systems with MMC topology in symmetrical monopolar configurations as they are currently the most frequent…
