Summary Fast measurements of the instantaneous amplitude and phase angle of the fundamental components and frequency in three-phase power systems may be investigated with high accuracy through the use of modern power instruments such as Phasor Measurement Unit (PMU). However, this accuracy may be affected by several encountering power disturbances, such as abrupt frequency deviation, fast and slow dc offsets decaying due to sudden current changes, inter-harmonics, etc. To avoid these effects for improving the quality of measurements, this work presents a new method of real-time filtering for removing the unwanted DC offset and hence improving SDFT algorithm. To validate the proposed method, the performances of PMU are tested using the data generated by Simulink/MATLAB simulator. The obtained results are very encouraging. Synchronized phasor measurements, or synchrophasors, provided a real-time measurement of conditions. Frequency and phase angles were monitored both within the island and on the power grid. By using synchrophasor technology, frequency and phase angle in the two systems could be compared in real time without the use of a physical connection. From this information we can come to know the use of synchrophasor data to view frequency stability, verify system independence, and observe the synchronization point. Phasor measurement units, together with synchrophasor collector and display software, provided valuable data. Finally, this paper will review the application of synchrophasors to observe power system dynamic phenomenon and how they will be used in the real-time control of the power system.
