Methods for Specification of Functional Requirements of Protection, Automation and Control

Protection, Automation, and Control systems for the power industry are currently developed following a well-defined engineering process. Many international standards and proprietary methods are available to this process, using advanced tools to support their development. Despite this status, a recent survey conducted by CIGRE Task Force TF B5.02 identified a lack of support of advanced methods for the primary user to specify the functional requirements for these systems, requiring the knowledge of technologies used for their implementation. This is particularly difficult considering the highly specialized knowledge needed to develop systems based on IEC 61850 and other PAC standards.
