Abstract

This document gives guidelines on the current asset management perspectives for HVDC installations based on best practices of asset owners, operators, users, original equipment manufacturers and regulators within the power industry. Asset management is a set of systematic and coordinated activities and practices through which an organization optimally and sustainably manages its asset and asset systems, their associated performance, risks and expenditures over their life cycles for the purpose of achieving its organizational strategic plan. An asset management system is the embodiment of the asset life cycle starting from asset planning, creation, utilization, operation, maintenance, and to the extent of, the retirement and disposal of the asset. It consists of the organization’s asset management policy, asset management strategy, asset management objectives, asset management plans and the activities, processes and organizational structures necessary for their development, implementation and continual improvement. The scope is limited to the DC plant/equipment side of the HVDC system including related AC components of the HVDC converter station. This document covers all equipment of HVDC converter station and electrode station but does not include DC lines and cables. This document covers HVDC systems with Line-Commutated Converters (LCC) and can be generally applied to Voltage Sourced Converters (VSC), not including specific equipment or sub-equipment required under VSC. This document on asset management covers: a) policy and strategy; b) training; c) information management; d) change management; e) life-cycle costing; f) tools; g) performance monitoring and measurement; h) documentation, operation and maintenance; and i) risk management. This document provides base guidelines on fundamental aspects and prudent practices to be considered by stake holders in managing HVDC assets. Compliance to additional requirements and recommendations stipulated in this document by the supplier or OEM are non-obligatory, unless explicitly specified by the customer. The guideline was prepared based on the following references to establish best practices: – published documents from other related organizations e.g. CIGRE; – an international survey on current practices of HVDC installations conducted by IEC TC 115 (see Annex B); – regional and international forum on management of HVDC assets; – HVDC user working group; and – asset management practitioners. The international survey document and results on the asset management practices are available with the Secretariat of IEC TC 115. The main objective of this document is to highlight an asset management standard framework for HVDC installations based on best known industry practices. This guideline can be beneficial as reference document in the management of HVDC assets.
