Adquisición de datos e implementación de una interfaz gráfica para la evaluación del estado de operación de la central Illuchi 2 a través de registros de perturbación en estándar COMTRADE

Abstract

This project presents the acquisition and handling of the data which is stored in the protective relay used at the Illuchi 2 power plant. In this project, an algorithm is developed to evaluate the operation state of the Illuchi 2 Power units; finally the field implementation of the complete system is described. The data saved in the protective devices is acquired by its Original Equipment Manufacturer (OEM) software. The obtained data is handled and all calculations are performed in MATLAB. Illuchi 2 Power Plant Graphic Interface (IGCI) is an HMI software developed in GUIDE. This HMI helps to evaluate the steady state operation point of a generator using a COMTRADE file analysis as follows: 1) data processing, 2) reactive capability curve drawing and 3) generator’s steady state operation point location. Finally IGCI offers the possibility of creating and exporting a Microsoft Excel (*.xls) file report. Both the data acquisition and processing methods give reliable final results. The tool presented in this project is applied to the Illuchi 2 power plant generators of Cotopaxi Electric Energy Distribution Company (ELEPCO S.A.). Moreover it opens the possibility to analyze any other generation units that count with the IGCI software requirements.
