Implementación de un sistema SCADA enfocado en el proceso de generación y distribución de energía eléctrica para la subestación 4 de la EERSA.

Abstract

Riobamba Electric Company S.A. (EERSA) does not have a redundant system capable of ensuring the continuous monitoring of its substations in case of being interrupted by unexpected events which can have an economic and social impact on each occasion; therefore, the objective of this present graduate research was to implement a SCADA system focused on the process of generation and distribution of electricity for the Substation 4 of the EERSA. The methodology used incorporates quantitative, qualitative, and experimental approaches; the signals from the substation were acquired and filtered for integration with the SCADA system using Axon Builder 3 software, the Configuration of the system was set up to establish the connection using the IEC 60870-5-104 communication protocol, the design of the HMI (Human-Machine Interface) was carried out following the guidelines of the ANSI/ISA-101 standard, simulations were conducted to test the sending and receiving of data from the configured signals, operational tests were performed with one of the feeders to verify that the transmission of commands to the substation occurs smoothly., and the value of the data acquired from the analog signals of the SCADA system was compared with those of the reference equipment ADMS of the EERSA. Through the mentioned methodology, it was possible to determine that the Axon Builder software had a shorter response time; likewise, it was confirmed that the voltage, current, and power values obtained with the SCADA system and those obtained with the ADMS coincided successfully. In this context, the SCADA system developed with Axon Builder was demonstrated to be more efficient in terms of the signal response time; the data obtained in the SCADA system through analog signals matched those of the reference ADMS equipment, validating its use as a replacement.
