摘要：
The converter stations are the essential nodes in an UHV DC transmission system. To evaluate the seismic vulnerability of the UHV converter stations as a whole system, the converter station is divided into several critical loops and a corresponding systematic functional logic model is built up according to the layout and logic relationships of the equipment loops in the converter station. Taking the delivery of the electric power after the earthquake as the system performance evaluation index, the systematic functional state is classified into five levels. Based on the seismic failure probability model of the divided subsystems, the failure probabilities and the seismic vulnerability curves in different functional states of the converter station system under different seismic intensities are obtained via the enumeration method with the failure mode and the impact analysis. And the weak links of the converter station system is identified through the sensitivity analysis of the vulnerability parameters of the divided subsystems. © 2022, Power System Technology Press.
