Desenvolvimento de um registrador de perturbações nos sistemas elétricos.

Abstract

The structure and design considerations of a real-time disturbance recorder in electrical systems are presented. The acquired data are processed later to evaluate the behavior of the electrical system. The proposed register is composed of two units, one for data acquisition (UAD) and the other for the processing of acquired data (UPD). In the UAD and the monitoring of the electric system by the acquisition of system data. Afterwards, the acquired data are analyzed in the UPD, in the form of graphs representing the behavior of the electrical system variables (frequency, active power, reactive power and voltage). The proposed disturbance recorder allows flexibility from the programming point of view of the type of disturbance to be recorded. This means that the system operator can make a study of the behavior of the electrical system, from pre - defined conditions. The disturbance recorder comprises a data acquisition board, from which the electrical system is monitored and an IBM-PC type microcomputer is carried out, where the behavior of the electrical system is studied. of the graphical analysis of the quantities.
