Life cycle management on the operation of 400 MW power generation

Abstract

The purpose of this paper is to study the Life Cycle Management (LCM) on the operation of 400 MW Coal Fired Power Plant (CFPP). LCM is an effort by an asset manager to improve the condition of an asset in the middle life of CFPP in order to achieve the optimum value of an asset so that it is expected to meet the desired target. The value referred to in the research is an aspect formed by revenue and mid-life refurbishment cost that is influenced by factors such as safety, reliability, cost, and market price of electricity. In order to make the best decision in the middle of the operating period, a new methodology from LCM analysts is proposed by involving Life Cycle Cost (LCC) analysis. LCC analysis begins with developing failure rates and cost data followed by performance and cost assessment of several alternatives to obtain the most optimum alternative. The costs referred to LCC analysis consist of deterministic costs (mid-life refurbishment costs) and probabilistic costs (damage costs, repair costs, spare parts, lost gross margin) affected by failure rates. By involving LCC analysis in LCM analysis, the project costs and asset involved in LCM analysis can be estimated to find the best management strategies alternative of CFPP based on performance achievement that are represented in several graphs related to cost and reliability. LCC analysis can be involved in LCM analysis to assess effective management programs through the best alternative choices that meet the optimum value for safety, reliability and cost.
