IEC TR 60919-1:2020(E) provides general guidance on the steady-state performance requirements of high-voltage direct current (HVDC) systems. It concerns the steady-state performance of two-terminal HVDC systems utilizing 12-pulse converter units comprised of three-phase bridge (double-way) connections, but it does not cover multiterminal HVDC transmission systems. Both terminals are assumed to use thyristor valves as the main semiconductor valves and to have power flow capability in both directions. Diode valves are not considered in this document. This edition includes the following significant technical changes with respect to the previous edition: - Figure 8 and Figure 20 have been updated, a new Figure 18 "LCC/VSC hybrid bipolar system" has been added; - the HVDC system control objectives have been supplemented; - additional explanations regarding the HVDC system control structure have been given; - a new subclause 13.6 on HVDC system protection has been added.

Abstract

Overview

IEC TR 60919-1:2020 is an IEC technical report that gives general guidance on the steady‑state performance of two‑terminal high‑voltage direct current (HVDC) systems using line‑commutated converters (LCC). This fourth edition (2020) focuses on systems built from 12‑pulse converter units with three‑phase bridge connections and assumes thyristor valves at both terminals (diode valves and multi‑terminal HVDC are excluded). The edition adds updates to figures, supplements HVDC system control objectives and structure, and introduces a new subclause on HVDC protection.

Key topics and technical requirements

The report addresses steady‑state aspects that are essential for planning, specifying and operating LCC HVDC links:

Types of HVDC systems and converter transformer arrangements (clauses 4.x) including bipolar, monopolar, back‑to‑back and LCC/VSC hybrid bipolar configurations.
Rated power, voltage and current definitions and requirements (clause 6).
Equipment capability and overload considerations for valves, transformers, reactors and filter banks (clause 7).
Minimum power transfer, no‑load stand‑by and reduced direct‑voltage operation (clause 8).
AC system interaction: voltage, frequency ranges, system impedance and harmonic sources (clause 9).
Reactive power needs and supply for conventional and series‑capacitor compensated schemes (clause 10).
HVDC transmission line and earth electrode parameters for overhead lines and cables (clause 11).
Reliability metrics, outage definitions and availability calculations (clause 12).
HVDC control: objectives, hierarchical control structure (converter firing, pole, substation and master control), control limits and redundancy (clause 13).
Protection, measurements and telecommunication requirements (new subclause 13.6; clauses 13 & 14).
Auxiliary power, batteries/UPS and audible noise considerations (clauses 15–16).

Applications and who uses it

IEC TR 60919-1 is practical for:

HVDC project engineers and system designers specifying steady‑state performance and interfaces.
Utilities and transmission system operators defining performance, availability and reliability requirements.
Manufacturers of converters, transformers, reactors and protection/control systems for compliance checks.
Consultants, planners and regulatory bodies assessing HVDC link behavior, reactive power needs and AC interactions.
Operations teams for establishing control setpoints, redundancy and telecommunication needs.

Related standards

Refer to IEC technical committee publications on HVDC, converter equipment and protection as complementary references. IEC TR 60919‑1 is intended as guidance for steady‑state performance; project specifications should cite it alongside applicable normative IEC standards for detailed test, safety and protection requirements.
