Abstract
El objetivo de esta memoria es presentar soluciones para mejorar la calidad de servicio de la línea de transmisión que abastece al Archipiélago de Chiloé.El estudio empieza con el análisis de las condiciones actuales de operación del sistema de transmisión eléctrica de 220 y 110 kV que distribuye de energía al Archipiélago. Para este análisis se realiza un estudio de demanda que se subdivide en lunes-viernes, sábado y domingo, abarcando tanto el horario punta como fuera de punta junto a un análisis semanal. El diagnóstico de estos análisis arroja que las peores barras son Quellón y Castro en media tensión respectivamente, siendo el mes de agosto y las últimas tres semanas de estudio los que presentan mayor número de datos fuera de norma durante el período invierno eléctrico.A continuación, se exponen los principales procesos que se deben emplear para modelar el sistema eléctrico en el “software” DigSilent PowerFactory.Luego de realizadas las simulaciones se sigue con la determinación de resultados procedentes de los estudios de operación con transposición, con Static Var Compensator (SVC-Compensador estático de reactivo) aplicado a Quellón y con el empleo de un SVC en Quellón y Castro simultáneamente.Por último, se muestran gráficos estadísticos, que indican que gran parte de la configuración propuesta cumple con la norma. Cabe señalar, que el estudio de transposición encargado por la empresa no produce mejoras porque las líneas internas de Chiloé son cortas. La calidad del servicio mejora con la implementación del SVC en Quellón en media tensión, y se beneficia aún más al implementar otro dispositivo SVC en la barra Castro en media tensión.
The objective of this report is to present solutions to improve the quality of service of the transmission line supplying the Chiloe Archipelago.The study begins with the analysis of current operating conditions of the power transmission system 220 and 110 kV which distributes energy to the Archipelago. For this analysis a demand study is subdivided into Monday-Friday, Saturday and Sunday, covering both the peak hours and off-peak with a weekly analysis is performed. The diagnosis of these analyzes reveals that the worst bars are Quellón and medium voltage Castro respectively, August and the last three weeks of study those with more data outside the norm during the winter electricity.Then the main processes to be employed to model the electrical system in the "software" DigSilent PowerFactory exposed.After making the simulations continues with the determination of results from studies transposition operation with Static Var Compensator (SVC-reactive Static Compensator) applied to Quellón and the use of a SVC in Quellón and Castro simultaneously.Finally, statistical graphs, indicating that much of the proposed configuration meets the standard is. It should be noted that the transposition study commissioned by the company does not produce improvements because Chiloe internal lines are short. Service quality improvement with the implementation of SVC in Quellón medium voltage, and even more benefits by implementing another SVC device in the medium voltage Castro bar.
