Scope

GB/T 40605-2021 is the English-translated version of 高压直流工程数模混合仿真建模及试验导则.

GB/T 40605-2021 gives guidance on building and testing digital-analog hybrid simulations of high-voltage and ultra-high-voltage DC transmission projects based on thyristor converters.

It covers the real-time digital simulator, the digital models of the AC system and of the DC primary system, the architecture and functional design of the physical control and protection system, and the electrical and optical signal interfaces between the two.

It then sets out test verification of the control and protection functions and conformity tests, with the test items in Annex A. It is used to study AC-DC interaction, control and protection behaviour and updates of control and protection software, but not for factory testing. It was issued on 11 October 2021 and has applied since 1 May 2022.
