[296143] Automation of Calibration of Instruments In The Excitation System of The Generating Units of Itaipu Binacional
Autores: Ricardo Tadashi Kobayashi, Rafael de Oliveira Barreto, Ana Elizabeth Corrales Zelaya
Resumo: This paper presents a system developed to automate voltage transducer calibrations used in the excitation system of the generating units at Itaipu Binacional. To improve efficiency and ease of operation, our system deploys multiplexed measurements to reduce the calibration runtime and is controlled by an application designed with Labview. After development, we validated the system through comparisons between manual and automated calibrations, performed with the assistance of the normalized error metric. Finally, the automatic calibration system brought greater standardization of procedures and up to a 65,7% reduction in the time spent on calibrations.
