abstract

• Phasor measurement units (PMUs) synchronize the measurements of current and voltage phasors in real time. This paper introduces a PMU simulation model for phasor estimation which uses a nonrecursive Discrete Fourier Transform (DFT) algorithm with linear interpolation. The algorithm was implemented and tested in the Real-Time Digital Simulator (RTDS). The algorithm is evaluated using the test signals in the standard set IEEEC37.118.1. The results are within the standards established for variations in the voltage amplitude, but frequency variation errors increase as frequency increases, since the DFT is designed to operate only at a fixed frequency. © 2016 IEEE.
