| Abstract | |
Monitoring systems are a determining factor in any process, even more significant in power electrical systems. In this context, synchrophasor measurement units (PMUs) have been installed in many electrical systems around the world. This equipment is capable of monitoring the dynamics of power electrical systems by means of high-sampling mea- surements of magnitudes and angles of voltages/currents, frequency and rate of change of frequency synchronized with a satellite signal in Universal Time Coordinates (UTC). With the installation of PMU’s in several strategic points it is possible to obtain descrip- tions of the dynamic behavior of the power electrical systems, which would aggregate to the system operator a large amount of data that would help in several different pur- poses, from monitoring the voltage profile to studies and adjustment of mathematical models of the electric system conditions. In recent years, the most widely used phase estimation method has been the DFT, whose direct implementation is known as the Fast Fourier Transform (FFT), which provides excellent results under steady state conditions (constant frequency). However, it does not provide adequate accuracy under sudden os- cillations and transients, where amplitude and phase vary in time. An alternative method for estimation is the use of the dynamic phasor, which brings higher accuracy under dy- namic system events. The main objective of this work is to develop, test and validate a PMU platform using the Taylor Fourier Transform (TFT) estimation method, which is based on the use of dynamic phasors (AU) | |
