Scope

Main technical content: "This document specifies the calculation method for the amplitude and waveform of overvoltage generated on the grounding electrode lines of both sides when a single-pole grounding fault occurs on the DC transmission lines or the high-voltage DC transmission lines of the converter stations on both sides of the ±800 kV high-voltage DC transmission system. This document is applicable to the line-commutated converter (LCC) high-voltage DC transmission systems of the ±800 kV grade. For high-voltage DC transmission systems of other voltage grades and wiring modes, this document shall be implemented as a reference."
