| Abstract (English): |
This document presents a methodology for the design of an Automatic Load Shedding scheme (ALS) for electrical systems that serve oil extraction facilities. The oil field, throughout its operation life, has experienced problems in its electrical generation system, which has caused its total collapse due to low frequency. The electrical system is modeled in ETAP simulation software, including the dynamics of the generators and their control systems (automatic voltage regulators and speed regulators) considering typical parameters, the models are validated through measurements obtained from the SCADA system. Through time domain simulations, the evolution of the frequency in the face of generation loss is obtained for various operating scenarios; these scenarios are classified based on the rate of change of frequency (ROCOF). A list of load priorities for disconnection is generated. Finally, an adaptive EAC and EAC based on fixed frequency and ROCOF are proposed, whose performance is compared through dynamic simulations.

Este documento presenta una metodología para el diseño de un Esquema de Alivio de Carga (EAC) para sistemas eléctricos que sirve a facilidades de extracción de petrolero. El campo petrolero, a lo largo de su operación, ha experimentado problemas en su sistema de generación eléctrica, lo cual ha ocasionado colapsos totales por baja frecuencia. El sistema eléctrico del campo es modelado en software de simulación ETAP, incluyendo la dinámica de los generadores y sus sistemas de control (reguladores automáticos de voltaje y reguladores de velocidad) considerando valores típicos y validando los modelos en base a mediciones obtenidas del sistema SCADA. A través de simulaciones en el dominio del tiempo, se obtiene la evolución de la frecuencia ante la perdida de generación para varios escenarios operativos; estos escenarios son clasificados en base a la tasa de cambio de la frecuencia (ROCOF). Se genera una lista de prioridad cargas para su desconexión. Finalmente, se proponen un EAC adaptativo y EAC de frecuencia fija y ROCOF, cuyo desempeño es comparado a través de simulaciones dinámicas. [ABSTRACT FROM AUTHOR] |
