This paper discusses phasor and frequency estimation techniques with low computational cost for measurements in the power system. The objective of the paper is to investigate the use of hardware to improve accuracy in measurements while maintaining the low computational cost. The phasor estimation algorithms are usually based on Discrete Fourier Transform (DFT) while the frequency is obtained by angle...
This paper presents the development of a platform for automatically testing Phasor Measurement Units (PMU). In order to develop such platform, it is proposed a multitasking application for PMUs testing in accordance to the Synchrophasors Measurement Standard IEEE C37.118.1-2011. The application is managed by a personal computer with visual interface, which allows the user to configure signal parameters...
This paper present the developments of a low-cost Phasor Measurement Unit (PMU) for smart grid monitoring. This PMU is being developed for large-scale use in the distribution system allowing to monitor local and transmission level events. The device provides magnitude, angle and frequency data of the AC voltage in a synchronized way, between any point in the electrical system, even geographically...
