Full title and description

Rotating electrical machines - Part 16: Excitation systems for synchronous machines - Chapter 2: Models for power system studies. Recommends modelling guidelines and appropriate models for excitation systems for use in power system stability studies and includes a nomenclature defining the parameters and variables used.

Abstract

This technical report provides recommended modelling guidelines and a set of standard mathematical models and nomenclature for excitation systems of synchronous machines to be used in power system stability studies. It balances detail and computational practicality by presenting models for DC, AC and static exciters, control elements and common simplifications for stability analysis, together with parameter definitions and example representations for computer studies.

Scope

The report recommends excitation-system models suitable for steady-state, fault-interval and post-fault oscillation analysis in power-system stability studies. It defines a consistent nomenclature for parameters and variables, gives graphical and mathematical model representations and describes the assumptions and typical simplifications used when modelling excitation systems for stability studies. The report excludes detailed modelling of torsional shaft interaction, out-of-step behaviour, sub-synchronous resonance effects and detailed protection equipment.

Key topics and requirements

• Standard models for DC exciters (separately excited and self-excited field windings) suitable for stability studies.
• Models for AC exciters and brushless arrangements with simplified and detailed options.
• Static exciter (potential-source and compound-source) modelling, including rectifier and regulator characteristics.
• Representation of voltage control elements, limiters, and interfaces for power system stabilizers (PSS) where applicable.
• Consistent nomenclature, parameter definitions, per‑unit conventions and worked examples for computer implementation.

These topics reflect the report's purpose to provide practical, interoperable models for power-system stability studies.

Typical use and users

Engineers and analysts performing power-system stability and transient studies; developers of dynamic simulation software for power systems; manufacturers and designers of synchronous machines and excitation systems; research organizations and utilities seeking standardized model definitions and parameter nomenclature for interchanging data and validating system studies.

FAQ

Q: What is this standard?

A: IEC TR 60034-16-2:1991 is an IEC Technical Report that provides recommended models and a consistent nomenclature for excitation systems of synchronous machines to be used in power-system stability studies.

Q: What does it cover?

A: It covers modelling guidelines and representative mathematical models for DC, AC and static exciters, control elements (including interfaces for stabilizers), and parameter nomenclature and examples for implementing the models in stability simulations. It is aimed at steady‑state, fault‑interval and post‑fault oscillation analysis rather than detailed mechanical or protection phenomena.

Q: Who typically uses it?

A: Power-system dynamic analysts, software developers for dynamic simulation tools, machine and exciter manufacturers, utilities and academic researchers engaged in stability and transient studies. The report is intended as a reference for model implementation and data exchange.

Q: Is it current or superseded?

A: The document was published in 1991 (Edition 1.0) and is a published IEC Technical Report; IEC lists a stability date in its catalogue record. A later project to produce an IEC Technical Specification (TS 60034-16-2) was created but shown as deleted/abandoned in IEC project records; users should check the IEC catalogue or national adopters for the latest status before relying on it as the authoritative current document.

Q: Is it part of a series?

A: Yes — it is Chapter 2 of Part 16 of the IEC 60034 series on rotating electrical machines and is intended to be used alongside other parts of the IEC 60034 collection that address machine characteristics, testing and related excitation/control topics.

Q: What are the key keywords?

A: Excitation systems, synchronous machines, stability modelling, DC exciter, AC exciter, static exciter, nomenclature, power-system dynamics.
