Summary
Technological changes are being introduced into modern power systems to facilitate the transition to a clean energy future and to enable more flexible power networks. However, these technological changes have introduced new Electromagnetic Compatibility (EMC) problems in these systems and have also exacerbated some existing ones. This Technical Brochure (TB) addresses the emerging EMC issues in modern power systems that are expected to persist in future power systems.
The TB explains the nature of EMC issues and presents the problems of intra-system interference in modern power systems and the problems of inter-system interference between power systems and both the natural electromagnetic environment and other man-made systems. Rather than providing an exhaustive bibliographical review, the TB presents the stage of development of understanding of each of these problems, as well as the relevant suppression techniques and standards.
This document is intended for all power systems engineers seeking a more detailed understanding of the increasingly complex interactions between the various components of modern power systems and aims to raise awareness of EMC issues that are exacerbated by the new characteristics of these systems. These is achieved by explaining an engineering simplification of the full electromagnetic view, known as EMC, which is more comprehensive than circuit theory because it also includes signals originating directly from electromagnetic field quantities.
