Maintenance Decision Models for Java–Bali 150-kV Power Transmission Submarine Cable Using RAMS

The application of reliability, availability, maintainability, and security (RAMS) analysis is currently developing in many fields of an electrical power system. The focus of this paper is to demonstrate the applicability of RAMS to analyze maintenance planning on the 150-kV submarine cables of the Java-Bali power transmission system in Indonesia. In this maintenance decision model, four alternatives of a maintenance scheme are made based on maintenance interval and cable's mechanical protection. Monte Carlo simulation will be used to obtain a RAMS value of each alternative. The decision is made based on a cost-effectiveness parameter using a life cycle cost analysis.
