scope:

This guide describes the general requirements, functional and technical performance requirements, test requirements, labeling and packaging requirements, transportation and storage requirements, supply integrity requirements, and quality assurance requirements for hybrid high-voltage direct current (HVDC) transmission control and protection equipment.

This guide is applicable to control and protection equipment of parallel two-terminal or multiterminal hybrid dc transmission systems, which contain line-commutated converter (LCC) valves and modular multilevel converter (MMC) valves, and can be used as the basis for equipment design, manufacturing, testing and acceptance.

Purpose

The purpose of this document is to provide guidance on general, functional, performance, labeling, packaging, transportation, storage, supply integrity, and quality assurance characteristics of hybrid HVDC control and protection devices.
