The CIGRE Session 2008 includes a discussion meeting on Protection and Automation.
These meetings are based on a "Special Reporter" system.
The session papers that have been submitted and accepted for inclusion in the conference are actually not presented by the authors during the meeting. Instead, they are discussed by the delegates as responses to the questions formulated in Special Reports.
Protection and automation subjects are covered by Study Committee B5, focused on "Principles, design, application and management of power system protection, substation control, automation, monitoring and recording - including associated internal and external communications, substation metering systems and interfacing for remote control and monitoring.."

Recent wide-area electrical disturbances have clearly demonstrated the vulnerability of the interconnected power system when operated outside its intended design limits and have shown that protective relay systems are very often involved in major wide area perturbations. This important topic was recently addressed by the IEEE Power System Relaying Committee (PSRC). The working group C12 has created a report on Performance of Relaying during Wide-Area Stressed Conditions. The report addresses key aspects of relaying schemes during wide-area disturbance conditions such as: performance; equipment rating; settings and coordination; dependability vs. security; and maintenance. It describes key stressed system conditions that affect conventional protection schemes, analyzes field experiences under stressed conditions, and suggests proven methods and solutions to improve protection performance and minimize disturbance propagation.More
