Abstract

Current developments in the electricity grids demand for an optimal utilization of existing grids. To make this possible, more measurement, communication, computing, active control equipment and automation needs to be implemented into the grids. As a consequence, this entails extremely high loaded transmission corridors. While such operation is on the one hand a big challenge from a grid control perspective, the protection systems too need to behave securely and dependably under such circumstances. This work discusses the various ways in which conventional protection systems are influenced by extreme loading using the example of distance protection. After that, numerous existing solution approaches to these challenges are presented. The described methods can be categorized in those that directly improve the behaviour of the relays and those that concern the protection congestion consideration in the control centres. They range from small adjustments like changed safety factors to adaptive techniques to avoid constant worst-case assumptions to modified measurement algorithms and completely new designed fault detection and localization approaches. It is highly probable that the field of secure and dependable protection systems in extremely high loaded grids will be of increasing importance in the future.
