High Voltage, EarlyView.ABSTRACT The harmonic current and vibration of a converter transformer are effective pieces of information for detecting mechanical faults in the winding. In this paper, the ratio of vibration acceleration to the current squared is defined as the vibration frequency response function (VFRF) of the winding, and then, a novel online vibration frequency ...

A review of LCC-HVDC and VSC-HVDC technologies and applications
2016 IEEE 16th International Conference on Environment and Electrical Engineering (EEEIC), 2016 High Voltage Direct Current (HVDC) systems has been an alternative method of transmitting electric power from one location to another with some inherent advantages over AC transmission systems. The efficiency and rated power carrying capacity of direct current transmission lines highly depends on the converter used in transforming the current from one ...

A Hybrid Ultra‐High Voltage DC Transformer With Digital Twin‐Driven Operation and Control
Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.This study introduces a digital twin‐driven hybrid ultra‐high‐voltage DC transformer (UHVDCT) that combines high‐capacity LCCs with low‐capacity MMCs at the UHV side. This innovative topology reduces MMC requirements by 32.9% while ensuring stable power flow and dynamic reactive balance through real‐time virtual‐physical synchronization.
