HVDC Thyristor Valve Design Guidelines

1 Scope

GB/Z 30424-2013 is the Chinese national standard on design guidelines of thyristor valves for high voltage direct current (hvdc) power transmission, in the field of electrical engineering. The /Z suffix marks it as a guiding technical document: it does not prescribe requirements that can be certified against, but sets out the technique, the method or the state of the art that the standards bodies recommend following. It was issued on 31 December 2013 by the State Administration for Market Regulation; Standardization Administration of China. As a guiding technical document it carries no separate date of entry into force: it applies from publication. Classification: ICS 29.200, CCS K46. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This guideline specifies the basic requirements for the design of thyristor valves for high voltage direct current (hereinafter referred to as valves). This guidance applies to water cooled, air insulated, and indoor mounted valves.

3 Terms and definitions

GB/T 13498 defined and the following terms and definitions apply to this document.

3.1 Maximum direct current maximumdirectcurrent Valve under the specified operating conditions, (theoretically unlimited time) to the load output of the maximum DC current.

Note. Generally different cooling media and ambient temperature have different values. 3.2 2h overload DC current 2hoverloaddirectcurrent Valve within the specified 2h, can output to the load DC current.

Note. Generally different cooling media and ambient temperature have different values.

3.3 Short-time overload (overload) DC current shorttimeoverloaddirectcurrent Valve in the specified short period of time (such as 10s, 5s, 3s), to the load DC current output.

Note. Thyristor current stress is the primary limiting factor.

3.4 Rated DC current rateddirectcurrent According to the provisions of the load conditions and conditions of use, the manufacturer for the inverter DC current (average).

3.5 Maximum ideal no-load DC voltage maximumidealno-loaddirectvoltage Generally refers to the inverter in the case of no-load maximum DC voltage (Udi0max).

Note. At this point, all voltage drops and grid voltage fluctuations are neglected.
