To meet this goal we propose the design of a methodology based on self-healing schemes for restoration of service, known by the electric industry as FLISR (Fault Location, Insulator and Service Restoration) through a Predictive Reliability Model (PRM) using historical outage data, distribution feeder models and customer and feeder load data. The study area considers five real distribution feeders, representing around the 15% of the total distribution system. We start from the definition of a customized calibration system model, constantly trying that PRM reflects the historical reliability, as a relevant purpose, using a five year historical outage data and reliability indices (TTIK, FMIK, SAIDI and SAIFI). It´s also important to mention that failure rates and mean times to repair (MTTR) were assigned to the distribution equipment (fuses, breakers, reclosers, etc.). As a next step, we identify a set of reliability improvement projects that need to be implemented, summarize as a new planning criteria, fuse-clearing and fuse-saving overcurrent protection schemes and distribution automation schemes. According to SAIDI final results, we prioritized the execution of the mention projects. Finally, using these final results we have done a cost-benefit analysis, recommending to CENTROSUR a project portfolio to accomplish, in order to better its network reliability metrics, showing the advantages, versatility and potential of the proposed PRM.Item Diseño de esquemas de control integrado de tensión y potencia reactiva del sistema de distribución de la Empresa Eléctrica Regional Centro Sur C. A.(2014) Zhungur Procel, Alexis Omar; Calva Riofrio, Edwin Roberto; Ugalde Delgado, Juan HernandoThis work resents an alternative optimization schemes applied voltage for the integrated voltage control and reactive power (IVVC -Integrated Volt / VAR Control) under the concept of CVR (Conservation Voltage Reduction), in order to manage demand and increase energy efficiency in the distribution system feeders of CENTROSUR. Evaluated the potential benefits of this initiative are: energy saving, reducing the cost of capacity, reduction of CO2 emissions to the environment and loss reduction. A methodological guide for the preparation of information (construction of energy profiles of measuring points and load model), selection of candidates feeders (base case analysis) to quantify the benefits is proposed; supported by the software tool CYME. This analysis is to evaluate the voltage profile in each of the nodes of a feeder for the period of one year. The goal is to strategically place equipment regulation and control (voltage regulators and capacitor banks) to get flatten the profile and move within the ranges allowed by the CONELEC voltage regulator. This reduction scenarios voltage of 1 %, 2 %, 3 % and 4% in head, to quantify these benefits and get the CVR factor are evaluated.Item Diseño de una metodología para la reducción y control de pérdidas de energía utilizando índices sectorizados de pérdidas en alimentadores primarios para CNEL S.A. regional El Oro(2012) Castillo Abad, Edwin Rolando; Pérez Ayala, Angel Fernando; Ugalde Delgado, Juan HernandoItem Escenarios de contingencias para la automatización de la operación del sistema de distribución para los alimentadores primarios 0321, 0322 y 0722 de la Empresa Eléctrica Regional Centro Sur C.A.(2017) León Tenesaca, Marcelo Esteban; Ugalde Delgado, Juan Hernando; Neira Campoverde, Jaime PatricioThe main objective of this thesis is to obtain the contingency scenarios in the area delimited by the 0321 0322 and 0722 feeders of the Empresa Eléctrica Regional Centro Sur C.A. To achieve this goal is necessary to know the topology of the electric network, perform an analysis of the operation of the network, of the reliability and the protection, and apply them to find the location of the reclosers in the network. Also, it is necessary to study the criteria of N-1 and it is necessary to know the restrictions to execute load transfers between feeders. Later, in this document is described the most important architecture of models of automation, to determinate which is the model that fits the requirements of load transfers. CYMDIST was used to make all the analysis of the present work. Finally, the results show which considerations we have to considerate to automatize this area.Item Estudio de pérdidas de energía en los transformadores utilizados por las empresas ubicadas en la zona del parque industrial(2007) Bermeo G., Claudio Geovanny; Ugalde Delgado, Juan HernandoItem Estudio, determinación y control de las pérdidas de comercialización en la Empresa Eléctrica Azogues(1995) Rosales Rojas, Carlos Danilo; Moreno C., Mario; Ugalde Delgado, Juan HernandoItem Gestión de mantenimiento de redes eléctricas del sistema de distribución aplicado en el área de servicio de la agencia Gualaceo de la Empresa Eléctrica Regional Centro Sur C.
