1 Scope
This Technical Report provides general guidance on basic principles and general proposals
for the safe and economic operation and maintenance of an LCC converter station.
These guidelines are based on the operation and maintenance practices that have been
used successfully during the last decades at HVDC converter stations all over the
world, and can be referred to by new HVDC users to optimize operation and maintenance
policy and assist in performing the operation and maintenance work.
This document focuses only on the operation and maintenance of the equipment inside
an LCC converter station, including back-to-back HVDC systems. The operation and maintenance
of HVDC overhead transmission lines, HVDC cables and voltage sourced converter (VSC)
are not covered by this document.
NOTE Usually the agreement between the purchaser and the suppliers of the HVDC converter
station includes specific requirements regarding contractual requirements of particular
systems. Such specific requirements will supersede the general/typical description
mentioned in this document and all functions mentioned in this document are not necessarily
applicable for all systems.
