Full title and description

IEC TR 62511:2014 — Guidelines for the design of interconnected power systems. This Technical Report provides recommendations and good-practice guidance for planning and designing high-voltage transmission systems that form interconnected power systems (IPS), with the objective of enhancing system reliability and limiting adverse impacts from faults, disturbances and separations between areas.

Abstract

This Technical Report outlines recommended techniques and design/operation requirements to secure an interconnected power system so it can withstand primary contingencies and avoid widespread consequential failures. It addresses synchronous and asynchronous interconnections (including DC links), and offers guidance for defining control-area boundaries and subsets of large areas to contain adverse impacts. The guidance is non-prescriptive and intended to support system planners and operators in achieving a high level of reliability.

Scope

IEC TR 62511:2014 applies to the planning and design of high-voltage transmission systems that participate in interconnected power systems. It addresses technical and operational measures that reduce the likelihood and consequence of major system separations and cascading outages. The scope covers both synchronous connections and asynchronous (DC) interconnections and is intended for use by system planners, transmission system operators and those responsible for interconnection agreements and technical design arrangements.

Key topics and requirements

• Definition and delimitation of control areas and subsets within large systems to contain adverse impacts.
• Recommended design practices to withstand primary contingencies and maintain stability.
• Guidance on coordinated operation and design of synchronous and asynchronous interconnections.
• Measures to enhance system reliability and mitigate consequences of major disturbances or unintended separations.
• Operational considerations and recommended techniques for secure IPS design (planning criteria and resilience measures).

Typical use and users

This Technical Report is typically used by national and regional transmission planners, transmission system operators (TSOs), utilities, power system planners, consultants involved in interconnection projects, and regulators reviewing interconnection reliability requirements. It is a guidance document for stakeholders responsible for the design and secure operation of interconnected high-voltage networks.

Related standards

IEC TR 62511 is part of the IEC portfolio addressing power-system management and security; it complements other IEC/ISO/IEEE standards and technical reports on power system stability, operation and interconnection practices. National adoptions and translations (e.g., St IEC TR 62511-2014) and regional normative documents may reference or implement its guidance.
