Real-time Condition Assessment of Power System Assets as a Vital Information Backbone for a Comprehensive Online Asset-Management System

摘要

In course of cost reduction efforts at electric utilities the budgeting for physical assets appears to be the most crucial planning instrument. The operational practice shows yet that the existing cost prediction tools are not sensitive enough for reflecting fast condition developments in the periodic maintenance budget plan. As a result, decision makers take financial consequences of assets degradation into consideration only with substantial time delay. This leads to insufficient management of interacting business processes and consequently to considerable losses in the entire organization. The present contribution will demonstrate an iterative technique for determination of asset degradation required for budget calculation. The approach combines financial and engineering information and it allows the decision makers to follow the technical and financial risks as a function of time. The article will also illustrate, that the assets amortization and the required maintenance budget might be calculated by deploying the Fuzzy-Logic in real time.
