Resumen
Descripción
En este artículo se propone un método nuevo para la detección de isla en sistemas de generación distribuida. Dicho procedimiento se basa en la introducción de una perturbación a la salida del inversor con el fin de observar el comportamiento de la tensión en el punto de acople común (PCC), la cual dependerá de la impedancia conectada ⎯al PCC⎯ en la situación de isla. Así mismo, se efectuó un análisis comparativo entre las principales técnicas activas residentes en el inversor para detección deisla y su similitud con la propuesta. Los algoritmos mencionados en este artículo fueron simulados en PSIMTM y comparados para establecer sus ventajas y desventajas (basados en estándares IEEE).
This paper presents a new active anti-islanding detection method for distributed power generation systems. This method is based on introducing a disturbance at the inverter output and observing the behavior of the voltage at the point of common coupling (PCC), which depends on the impedance connected to the PCC in an islanding situation. Additionally, this paper presents the analysis and comparison of the main active techniques for islanding detection and these were comparewith the proposed technique. The algorithms mentioned in this work were simulated in PSIMTM inorder to make a comparative analysis and to establish their advantages and disadvantages accordingto IEEE standards.
