VASCHETTI, Jorge C; GOMEZ, Juan C  and  AMATTI, Juan C. Modeling and Simulation of an Voltage-Time Sectionalizer for Intelligent Protection including Distributed Generation of Electricity. Inf. tecnol. [online]. 2012, vol.23, n.2, pp.99-108. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642012000200012.

The modeling and simulation of a device that is part of an intelligent protection scheme. A voltage-time sectionalizer is proposed, as the basic unit of the system applied to an urban-rural distributor of electricity. The impact of distributed generation in the implemented scheme using a general purpose software simulation tool is demonstrated. This software allows implementing the finite state machine that models the proposed section of the protection scheme. An important result of this study is that the use of the proposed device maintains the coordination even with the inclusion of distributed generation. It is also clearly established the maximum number of sectionalizers that can be interconnected in series.

Keywords : intelligent protection system; electricity, distributed generation; voltage-time sectionalizer.
