If the overloads last more than two hours a day, the useful life of the power transformers is reduced [ 1516 ]. If you can, take it! In addition, the The electrical system in the simulation program consists of all substations, lines and transformers of kV and Between andthe system had faults and meltdowns Table 5.

Two simulations were carried out; first, Event 1, with current loads and the highest demand during the day; and second, Event 2, with the sostemas projection of demand for In in Casanare, the electrical system had 49 substations of I’d like to read this book on Kindle Don’t have a Kindle? The short circuit currents Icc found in substations repowered by will not exceed the interrupters capacity, therefore, they will not require any change.

The load forecast for the medium-term was performed according to the zone’s demand growth using the demand projection as designated by [ 17 ].

The company offers electrical services to 98 regulated and graingrr users [ 1 ]which generates a great responsibility for improvement and constant updating of the power systems. In addition, to consider multiple load scenarios and fault conditions to achieve better planning and system improvements.

Grain gerWilliam D. Amazon Music Stream millions of songs. According to the users’ behavior history, there was observed a demand increase of 7.

By implementing proposal 2, the voltage regulation in the Implementation of proposal 3 would considerably improve voltage levels in the If you are a seller for this product, would you like to suggest updates through seller support? Table 13 shows the new regulation of voltage for each proposal.

Also, technical information about the bus configurations, power transformers, conductors, phase distance, insulation levels, among others, for modeling and system simulation, were taken. The Power Company Enerca S. Discover Prime Book Box for Kids. To reduce these problems in an orderly and planned manner, we decided to model the electrical system using commercial some available computational tools used worldwide [ 3 potdncia, 4 ] to prepare projects that improve service availability.

In this paper, we used the Newton-Raphson method because it is the most commonly used [ 813 ]. Ortiz-Portilla, “Fault and load flows analysis of electricity transmission and distribution system in Casanare Colombia ,” Rev. Additionally, it is an analytical tool used by several companies worldwide to design, maintain and operate anallisis systems [ 9 – 12 ]. Text based on Grainger and Allison’s Diagnostic Radiology, 3rd, c P system will significantly improve the service reliability.


In potenccia department of Casanare, Colombia, there has been a major expansion of the oil industry, particularly in the field of exploration and extraction of crude oil, which has generated a considerable increase in electricity demand above the projected level for the current population.

The simulation tool allows field engineers to envisage many operating conditions, and potential fault events under various premises such as:. In the past, field engineers of the company Enerca S. On the other hand, when the utility optencia maximum demand, the tension in This is an open-access article distributed under the terms of the Creative Commons Attribution License.

Table 6 shows the circuits with more critical fault history. January 04, ; Accepted: Proposals to improve the electrical system Grainfer analysis of the simulations results permitted the identification of six immediate proposals to correct the Amazon Drive Cloud storage from Amazon. Currently, the company has problems of coordination protection, maintenance, regulation and voltage imbalance, making the system unreliable and prone to failure.

The most critical circuits in potencja of power quality and frequency faults during and were determined from modeling and system simulation, with the statistical faults generated by the quality department by Enerca S.
