Improvement in Taylor Weighted Least Square Based Dynamic Synchrophasor Estimation Algorithm for Real Time Application

A work on synchrophasor estimation algorithm design for real time dynamic power signal parameter measurements is presented here. The main advantages of two efficient algorithms, the zero-crossing detection (ZCD) and Taylor weighted least square (TWLS) are harnessed to present a simple and accurate synchrophasor and frequency measurement algorithm. Design parameters are analyzed and discussed for the simulation of algorithm. The algorithm performance is validated using simulations on LabVIEW virtual instrumentation platform, in light of different tests mentioned in IEEE synchrophasor standards, and also compared with existing TWLS algorithm. The accuracy of measurements on low sampling rate and window length confirms the suitability of the presented design for real time dynamic synchrophasor measurements.
