Integración de medidores de energía eléctrica de las bahías de las subestaciones del área de concesión de la provincia de Bolívar al sistema SCADA.

Abstract

The objective of this titling research work is the integration of electric energy meters in the inlets of the concession area in the province of Bolivar to the system of supervision, control and acquisition of data (SCADA). The integration of the meters to SCADA system consists of two stages, inlet stage and station stage. The first stage is composed of equipment that makes up each electrical substation controlled by a relay oriented to protect the equipment and composed of field equipment: current and potential transformers, responsible for transforming high voltage or current levels to lower levels that can be read and processed by measuring equipment. In the station stage there are ION 8600 energy meters whose function is to measure values of voltage, current, power and other electrical parameters, this meter establishes a low level communication protocol for the sending of information and establishes a communication channel Master- Slave through a Switch to the Remote Terminal Unit (RTU), to be part of the system where the complete system monitoring and control is performed. the integration of electrical energy meters to SCADA, optimized the acquisition accuracy of electrical parameters in 8.52% with respect to the previous system at Guaranda Substation and 14.33% at Guanujo Substation, allowing the Department National Electricity Corporation (Corporacion Nacional de Electricidad), to perform engineering calculations to determine aspects such as: expansion planning, improvements in the electrical system, improvements in the quality of service and a more accurate form of monitoring in real time. It is recommended to define the directions of the Master / Slave team to avoid internal communication conflicts and receive the exact required information for the respective analyzes in the lost department.
