Scope

1.0.1 In order to standardize the main technical principles for the design of valve halls in converter stations of ±800 kV and above ultra-high voltage direct current (UHVDC) projects, as well as the technical requirements for the design of electrical, civil, and auxiliary systems, so that the design of valve halls can comply with relevant national policies and regulations and meet the requirements of safety, reliability, advanced applicability, economic rationality, and environmental friendliness, these guidelines are formulated. 1.0.2 These guidelines are applicable to the design of valve halls above ground level in UHVDC transmission projects with double 12-pulse series connections at voltage levels of ±800 kV and above. 1.0.3 The design of converter station valve halls should take into account the specific circumstances of the project and adopt new technologies, new processes, new materials, and new equipment to ensure safety, applicability, technological advancement, economic rationality, and environmental friendliness. 1.0.4 For the design of valve halls in converter stations of ±800 kV and above UHVDC projects, in addition to complying with these guidelines, they shall also comply with the provisions of the relevant current national standards.
