GB/T 34118-2017Terminology for voltage-sourced converters ( VSC) for high voltage direct current (HVDC) systems (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the translation method identical with IEC 62747:2014 "high voltage DC system voltage source converter terminology." the documents of our country that are consistent with the corresponding international documents that are normative references in this standard are as follows.

--- GB/T 4728 (all parts) Electrical diagrams with graphical symbols [IEC 60617 (all parts)].

For ease of use, this standard made the following editorial changes and errata.

--- Removed the first paragraph of 3.1, due to the statement does not match the content of Chapter 3;

Errata "NGB S" to "NBGS" (see 3.3);

--- Corrigendum "CTL" to "CTLC" (see 3.3, 6.5 and Figure 4);

--- Figure 2 will be changed to Table 1, followed by the figure number change in turn;

--- Correct the "See Figure 3" in 7.10 note as "See Figure 4" and "See Figure 4" Corrigendum "See Figure 3". And, for the sake of easy expression, that's it

Note the first sentence and the second sentence of the position of exchange;

--- The formula (1) "M = 2 · Ucl 3 · Udc Corrigendum to "M = 2 × Ucl 3 × Udc "(See 8.11).

This standard proposed by the China Electrical Equipment Industry Association.

This standard by the National Standardization Technical Committee power electronic systems and equipment (SAC/TC60) centralized.

1 Scope

This standard defines the terms related to self-commutating voltage source converters for High Voltage Direct Current (HVDC) transmission.

This standard applies mainly to voltage source converter (VSC) based on IGB T (Insulated Gate Bipolar Transistor), based on the open Voltage source converters (VSC) for other types of semiconductor devices on and off can also be used for reference.

This standard does not apply to high-voltage direct current (HVDC) transmission system used in commutation converter and current source converter.
