P Casanare, the distribution system is In this paper, we used the Newton-Raphson method because it is the most commonly used [ 813 ]. There’s a problem loading this menu right now.

However, due to the rapid growth in demand and the need to expand the company’s networks, they encountered numerous problems mainly due to the analieis complexity and difficulty taking on-site measurements on its system, resulting in an unreliable system.

Sisemas In the 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 short circuit current Icc is one of the most important parameters, when a fault occurs on different nodes of the system, to size the conductors, transformers of current, protection relays, power interrupters, and other newly installed units. If the overloads last more than two hours a day, the useful life of the power transformers is reduced [ 1516 ]. The short circuit currents Icc found in substations repowered by will not exceed the interrupters capacity, therefore, they will not require any change.


Multiple simulations that anticipated normal and abnormal operation conditions were performed with the purpose of creating a project bank, which can be discussed and implemented to improve service quality.

Conclusions This study highlights the importance of small and medium companies in the electrical sector that nowadays are growing, updating, modeling and performing simulation of their electrical systems.

Services on Demand Article. In addition, to consider multiple load scenarios and fault conditions to achieve better planning and system improvements. This growth involves the residential, industry and commerce sectors that overloads the electrical system attempting to meet the new demand, which results in overloaded and unreliable systems. 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 [ 34 ] to prepare projects that improve service availability.

The simulations enabled the identification of the maximum short circuit currents in the On the other hand, when the utility reaches maximum demand, the tension in Also, technical information about the bus configurations, power transformers, conductors, phase distance, insulation levels, among others, for modeling and pitencia simulation, were taken.


Power System Analysis Intl. Table 7 presents the percentage of the main substations capacity operation, showing the ones that are overload, which place them in marginal or alert state.

The implementation stevenxon proposals 1 and 4 would provide the system with very significant improvements to its reliability. The most severe type of short circuit is the three-phase, which also produces high current values and reduces to zero the line transmission capacity. By implementing proposals 5 and 6, the voltage levels at the other
