摘要

Abstract

As high-voltage direct current (HVDC) lines with large capacity are being commissioned with higher frequency

the characteristics of “strong” DC and “weak” AC transmission in the power grid are topics of interest. In particular

the coupling and interaction between the sending-side and receivingside AC systems interconnected by large-scale DC links is gaining importance. In this paper

the impact of the multiple HVDC commutation failure on the stability of the sending system under different power flow directions is analyzed based on the threearea AC/DC equivalent model. The main influencing factors and the counter-measures are discussed

and the single HVDC line blocking is taken as a comparison. Finally

the results are verified using the North China-Central China-East China power grid case system. The study provides a basis and reference to ensure security and stability of the ultra-high-voltage (UHV) AC/DC hybrid power grid.
