Scope: This document specifies the basic technical requirements for equipment supervision services related to the manufacturing and quality of DC control and protection equipment for converter stations of high-voltage direct current (HVDC) transmission projects. This document applies to the supervision of the manufacturing of DC control and protection equipment for converter stations of HVDC projects with a double-12-pulse converter series structure. DC control and protection equipment for converter stations of HVDC projects with a single-12-pulse converter structure and a double-12-pulse converter parallel structure can be implemented as a reference. Main technical content: (1) This standard specifies the basic requirements for equipment supervision units to provide manufacturing supervision services for DC control and protection equipment. It applies to the manufacturing supervision activities of equipment supervision units, including design, procurement, manufacturing, installation, commissioning, acceptance, packaging, and shipment. This standard applies to the supervision of the manufacturing of DC control and protection equipment for converter stations of HVDC projects with a double-12-pulse converter series structure. DC control and protection equipment for converter stations of HVDC projects with a single-12-pulse converter structure and a double-12-pulse converter parallel structure can be implemented as a reference. (2) To standardize and unify the terminology of DC control and protection equipment and other related terms, this document proposes important terms and definitions related to the supervision of the manufacturing of DC control and protection equipment. (3) The supervision implementation process related to manufacturing quality is clearly defined. Appendix "A" is the main witness point project list for the supervision of the manufacturing of DC control and protection equipment, and Appendix "B" is the reference template for various forms used by
