This paper evaluates the Reliability of Onitsha power distribution network using analytical technique and the level of improvement achievable through application of photovoltaic (PV) system at injection substations. ETAP simulation software was used to run the power flow and reliability assessment of the Network. The investigation revealed that before the PV installations the total revenue lost...

The KM3NeT EU-funded consortium, pursuing a cubic kilometre scale neutrino telescope in the Mediterranean Sea, is developing technical solutions for the construction of this challenging project, to be realized several kilometres below the sea level. In this framework a proposed DC/DC power system has been designed, maximizing reliability and minimizing difficulties and expensive underwater acti...

A major challenge for the power utilities today is to ensure a high level of reliability of supply to customers. Two main factors determine the feasibility of a project that improves the reliability of supply: the project cost (investment and operational) and the benefits that result from the implementation of the project. This paper examines the implementation of an Artificial Intelligence Sys...

Looking to save money, enhance sustainability and ease compliance with environmental regulations, data center operators around the world are eagerly investigating new energy efficiency strategies. The most effective such strategies generally involve distributing power to IT loads at higher voltages, something data centers can do using either AC or DC power. This white paper discusses the leadin...

Original scientific paper Distribution network data archiving, editing and storing are permanent activities of high importance, obligated by legislation. The paper describes improved methods for the distribution`s power system fault data collection in the form of new developed components of operational database. The Visual Basic Code solution was developed to ease faults data input, data filter...

This research aims to develop data-driven methods that automatically exploit historical data in smart distribution grids for reliability evaluation, i.e., analyzing frequency of failures, and modeling components’ lifetime. The results enable power distribution companies to change from reactive maintenance to predictive maintenance by deriving benefits from historical data. In particular, the da...

Power transformers are the most complex, important and critical components of the transition and distribution power systems. Insulation system is the key component of life extension, better availability and higher reliability of a transformer. In order to achieve both decreasing operational cost and reliable service conditionbased maintenance is needed. Monitoring and diagnostic methods and tec...
