Assessment of overhead transmission lines is a crucial task in the asset management of electric power infrastructures. Any assets have different life spans and require proper assessment and maintenance actions. Disruption of the power supply may cause national problems. Therefore, it is essential to ensure that the distribution and transmission of...

... Additionally, it helps to reduce risk and ensure an effective enhancement of capital over an asset's 35 lifecycle (Shah et al., 2016). Asset management is also beneficial because it can lead to increased 36 knowledge of the assets, better operational decisions, improved emergency response, and greater 37 ability to plan and pay for future repairs and replacements (EFCNMT, 2006). ...
The asset management phase of a building constitutes approximately 60% of its total lifecycle costs. However, significant unnecessary expenses occur in current asset management practices because of the separation of the design and construction phases from operation and maintenance and the lack of an effective building asset management system covering all types of buildings with numerous components. Asset management decision-making is inherently a process that requires the assimilation of a multitude of data, processes, and software systems. Therefore, this paper proposes an integrated decision support system for building asset management that addresses the systematization and coordination of lifecycle data. In this approach, a lifecycle work breakdown structure (WBS) for the asset management system is developed to provide a unified hierarchy to categorize and organize building assets. It is then used to develop the WBS-based integrated lifecycle building asset management model through a relational database management system (DBMS). Since building information modelling (BIM) is a rich information-based platform with large volumes of asset data needed, it is integrated with the WBS-based DBMS to achieve an effective integrated building asset management. A case study of an educational building is presented and discussed in the paper to demonstrate how the proposed automated solution is used for asset management. The research contributes to the body of knowledge by formalizing a WBS-based unified asset inventory hierarchy and mapping BIM data to the proposed hierarchy for effective asset management.
... Through the analysis of physicochemical characteristics, it is then possible to evaluate the quality of both the oil and the transformer itself. These analyses are of great importance for the maintenance of electrical equipments, as they allow planned interventions to correct any defects and, in some cases, early failure diagnoses [11,12]. ...
... In the planning of a photovoltaic power plant the electric power produced is strongly linked to the meteorological conditions (solar radiation and temperature) [13,14]. Due to the intermittent nature of solar energy, power forecasting is crucial for a correct interpretation of business profitability and payback time [15]. ...
The amount of energy generated from a photovoltaic installation depends mainly on two factors—the temperature and solar irradiance. Numerous maximum power point tracking (MPPT) techniques have been developed for photovoltaic systems. The challenge is what method to employ in order to obtain optimum operating points (voltage and current) automatically at the maximum photovoltaic output power in most conditions. This paper is focused on the structural analysis of mathematical models of PV cells with growing levels of complexity. The main objective is to simulate and compare the characteristic current-voltage (I-V) and power-voltage (P-V) curves of equivalent circuits of the ideal PV cell model and, with one and with two diodes, that is, equivalent circuits with five and seven parameters. The contribution of each parameter is analyzed in the particular context of a given model and then generalized through comparison to a more complex model. In this study the numerical simulation of the models is used intensively and extensively. The approach utilized to model the equivalent circuits permits an adequate simulation of the photovoltaic array systems by considering the compromise between the complexity and accuracy. By utilizing the Newton–Raphson method the studied models are then employed through the use of Matlab/Simulink. Finally, this study concludes with an analysis and comparison of the evolution of maximum power observed in the models.
