Digital Substations: Feedback on Site Experience

Digital devices such as numerical protection relays and digital systems such as substation control are prevalent as the technology of choice in substations today.  This article looks at other substation areas into which digital technology has permeated, such that progressively, substations can become fully digital in their implementation.   Denmark is taken as a use case for a transmission Grid with a high penetration of renewable energy.  A policy to progressively underground the transmission lines has created operational challenges such as 400kV hybrid lines, with portions running cabled in areas of natural beauty.
