5.1 Introduction

Electric power systems have lately been operated dangerously close to their physical limits because of lack of investment, the use of congested transmission branches, and other technical reasons. Under these conditions, certain sudden perturbations can cause cascading events that may lead the system to blackouts. It is necessary to ensure that these perturbations do not affect security, so the requirement emerges of developing wide area protection schemes that allow guaranteeing service continuity. However, most actual wide area protection schemes are usually set to operate when specific pre-established operational conditions ...
