Scheme for on-Line Monitoring System of Converter Transformer

Abstract

To achieve a smart converter station, an on-line monitoring system for converter transformer is needed. Furthermore, it is the requirement for transition of maintenance strategy from ‘time-based maintenance’ to ‘condition-based maintenance’. This paper proposes a configuring of converter transformer on-line monitoring system based on the principle and application of on-line monitoring system for transformer, and the characteristics and operating environment of converter transformer. Architecture of converter transformer on-line monitoring system is also proposed on the basis of the 3-layer & 2-net structure applied in new smart substations and reconstruction. The designed scheme is suitable for transformation or new of smart converter transformer on-line monitoring system, which with good reference significance and application value.
