CIGRE B4.70 Global Webinar |4th May 2:00 – 3:30pm BST


Guide for Electromagnetic Transient Studies Involving VSC Converters

Tuesday 4th May 2021 | 2:00 – 3-30pm BST


The objective of the webinar is to present the TB written by CIGRE B4-70 WG. This TB aims to provide comprehensive, documented, and validated descriptions of transients and associated ElectroMagnetic Transient (EMT) models and studies for VSC-HVDC converters. The objective of the TB is 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 application of VSC-HVDC systems. Even though DC overhead lines, HVDC connection of wind farms, and multi-terminal/DC grids are outside the scope of this technical brochure, recommendations of the technical brochure can be slightly adjusted to be applied to these topologies. All simulations and analyses shown in the technical brochure are done with EMT simulation tools.
