IEC EN 60919-1 Performance of High-Voltage Direct Current (HVDC) Systems with Line-Changing Converters - Part 1: Steady State Conditions

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60919-1 testing. IEC EN 60919-1 provides general guidance on the steady-state performance requirements of high-voltage direct current (HVDC) systems. It relates to the steady-state performance of two-terminal HVDC systems using 12-pulse converter units consisting of three-phase bridge (bidirectional) connections, but does not cover multi-terminal HVDC transmission systems.

It is assumed that both terminals use thyristor valves as the main semiconductor valves and are capable of power flow in both directions. Diode valves are not considered in this document.

The difference between system performance specifications and equipment design specifications for individual components of a system is realized. Often the performance specifications for two HVDC substations in a given system are prepared as a single package. Alternatively, some parts of the HVDC system can be specified and purchased separately. In such cases, due consideration is given to the coordination of each part with the overall HVDC system performance objectives and the clear identification of each part's interface with the system.

The distinction is made between system performance characteristics and equipment design specifications for individual components of a system. Equipment specifications and testing requirements are not defined in this document. Detailed seismic performance requirements are also excluded from this document. Also, as there are many variations between possible different HVDC systems, this document does not cover them in detail; as a result, it is not used directly as a specification for a particular project, but rather to provide the basis for an appropriate specification tailored to suit actual system requirements.

In this arrangement there is no DC transmission line and both converters are in one place. Valves for both converters can be located in a single valve hall or even in a single integrated structure or individually as external valves. Similarly, control system, refrigeration equipment, auxiliary system, etc. Many other elements can be placed in one space or even integrated neatly into configurations common to the two converters. Circuit configurations can vary.
