研究目的
To analyze the financial feasibility study to ensure whether the Java-Sumatra Power Interconnection System project has economic benefit, and the asset would be used effectively and efficiently along its benefit period using life cycle cost analysis (LCCA).
研究成果
The study demonstrates strong correlation among project cost, failure, maintenance and risk of ENS with financial benefit and also the risk. It is shown that HVDC installation especially submarine cable need high cost for project capital but has very low probability of failure during operation. The application of Monte Carlo simulation gives a great advantage in handling dependency of many parameters and sub-system, but in the case of submarine cable it needs additional amounts of statistical data collected for more accurate evaluation.

1：Experimental Design and Method Selection:
The methodology involves the use of life cycle cost analysis (LCCA) to analyze three alternatives for the Java-Sumatra Power Interconnection System. Monte Carlo simulations and a break-even chart for a period of 30 years' operation of the interconnection system are part of the LCCA models.
2：Sample Selection and Data Sources:
The study uses data from PT Perusahaan Listrik Negara (Persero), Jakarta, Indonesia, and the Bandung Institute of Technology, Indonesia.
3：List of Experimental Equipment and Materials:
The study involves high voltage alternating current (HVAC) 500 kV Transmission Line in Java, HVAC 500 kV Transmission Line in Sumatra, high voltage direct current (HVDC) 500 kV Transmission Line in Java, HVDC 500 kV Transmission Line in Sumatra, and HVDC 500 kV Java-Sumatra submarine cables.
4：Experimental Procedures and Operational Workflow:
The study involves simulating three alternatives for the installation of the Java-Sumatra Power Interconnection System using LCCA and Monte Carlo simulations.
5：Data Analysis Methods:
The study uses Monte Carlo simulation techniques to join probability chance for failure, probability of ENS and economic data to solve problems of uncertainty.
