Abstract
VITERI TOQUICA, Diego; GARZON BUSTOS, Cesar and NARVAEZ CUBILLOS, Alexander. Reliability Analysis in Maneuver Type Electrical Substations Implementing Tension Transformer with Power Core. ing. [online]. 2017, vol.22, n.1, pp.65-82. ISSN 0121-750X. https://doi.org/10.14483/udistrital.jour.reving.2017.1.a09.
Context:
It is intended to conduct a technical study of a voltage transformer power core, used for the supply of the auxiliary services of a maneuver type substation, hoping to mitigate the possibility of losing the continuous electricity power supply and likewise reducing the dependency with the external supplier. This is a result of a collaborative project between the Bogota Energy Company and the Universidad Distrital Francisco Jose de Caldas.
Method:
The study consists of two stages, the first one is an analysis of reliability of the substation auxiliary systems, carried out in three scenarios: before and after use of the transformer and using a unique generator for auxiliary services. The second one is simulation using the ATP software to verify the behavior of the equipment in transient state.
Results:
The reliability of auxiliary services increased after the equipment has been installed, as the failure rate went from 0.31 [failure/year] with the current system, to become 0.0025 [failure/year]. Conclusions: The implementation of transformer is suitable for substations that do not have a reliable power system auxiliary services as it makes the substation auto dependent. Implement this system in Colombia would get a big increase in the reliability of the auxiliary services in maneuver type substations and therefore a lower probability of loss.
