IEC 62270-2013 (IEEE Std 1249) PDF

Full title and description

IEC 62270:2013 (published jointly as IEEE/IEC 62270-2013 and referenced by IEEE Std 1249) — Guide for computer-based control for hydroelectric power-plant automation. The publication is a dual-logo IEC/IEEE guide that gives recommendations for the application, design concepts and implementation of computer-based (digital) control systems used to automate hydroelectric generating plants.

Abstract

This guide describes system architectures, functional control capabilities, performance and hardware requirements, operator interfaces and training, communications and database considerations, testing and acceptance procedures, and recommendations for planning and implementing computer-based control systems in hydroelectric plants. It explicitly excludes detailed requirements for the electrical protective system (generator and step-up transformer). The 2013 edition is a technical revision of the earlier edition and updates architecture, communications and user/plant interface guidance, and adds material on legacy systems.

Scope

Provides guidance for specifying, designing and implementing computer-based control systems for hydroelectric power plants of varying sizes and configurations. Topics include recommended architectures (local, centralized, remote), control functions (start/stop, synchronization, turbine and pumped-storage control, plant power and voltage/VAR control), data acquisition and real-time database requirements, communications and network topologies (with preference for open standards), user interfaces and operator considerations, hardware and software performance and redundancy, testing, acceptance and operator training. The guide does not define detailed protective relay requirements for generators and step-up transformers.

Key topics and requirements

• System architecture options and recommended hierarchical/control configurations (local, centralized, remote/off-site control).
• Essential control functions: sequencing, synchronizing, turbine/generator control modes, pumped-storage management, plant-level active/reactive power control and black-start procedures.
• Data acquisition, alarm/event recording, time-stamping and archival requirements; real‑time database design and data integrity.
• Communications: recommended use of open communication standards, LAN topologies, interface requirements to field devices and substations.
• User/plant interfaces: ergonomic display design, operator controls, simulation and training system recommendations.
• Performance, reliability and redundancy: hardware considerations, fail-over behavior, backup control schemes and maintenance considerations.
• Testing and acceptance: recommended factory and site tests, commissioning checks and acceptance criteria.
• Legacy systems and migration: informative guidance on interfacing with and migrating from existing/legacy control installations (informative annex).

Typical use and users

Primary users are hydroelectric utilities, plant owners/operators, consulting engineers, system integrators, control-system vendors and equipment manufacturers. The guide is used to prepare specifications, evaluate supplier proposals, design control architectures, develop commissioning and test plans, and define operator training and maintenance procedures when implementing or upgrading hydroelectric plant automation.

Related standards

Commonly used alongside or referenced by implementers: IEC 61131 (programmable controllers), IEC 61850 (substation and field communications where applicable), IEC 61508 / IEC 61511 (functional safety guidance), ISO/IEC 27001 (information security management), and other IEEE and IEC power-generation and control standards. Earlier IEEE Std 1249-1996 is the previous IEEE guide edition that preceded the combined 2013 publication.

FAQ

Q: What is this standard?

A: IEC/IEEE 62270:2013 (also referenced as IEEE Std 1249 when used in IEEE catalogs) is a joint IEC/IEEE guide that provides recommendations and good practices for computer-based control and automation of hydroelectric power plants.

Q: What does it cover?

A: It covers system architecture, control functions, data acquisition and real-time databases, communications and interfaces, user/operator interfaces and training, hardware and software performance and redundancy, testing and acceptance procedures, and guidance on legacy system integration. It does not specify protective relay requirements for generators and step-up transformers.

Q: Who typically uses it?

A: Utilities, plant operators, engineering consultants, control-system integrators, equipment OEMs and project managers involved in specification, procurement, implementation and commissioning of hydroelectric plant control systems.

Q: Is it current or superseded?

A: The 2013 edition (Edition 2.0) supersedes the earlier (2004) edition; vendor and publisher listings show the 2013 edition as the active/current guide. Check IEC or IEEE catalogs or national standards bodies for any more recent revisions or stability/withdrawal notices.

Q: Is it part of a series?

A: It is a stand-alone IEC/IEEE guide focused on hydroelectric plant automation but is commonly used together with other IEC and IEEE standards for control, communications, safety and security in power systems (examples: IEC 61131, IEC 61850, IEC 61508, ISO/IEC 27001).

Q: What are the key keywords?

A: Hydroelectric, automation, computer-based control, digital control, system architecture, data acquisition, communications, operator interface, testing, redundancy.
