In this paper

starting from the “double-high” characteristics of power grid becoming more and more prominent

resulting in the increasing demand for related measurement and the corresponding increase in measurement requirements

It comprehensively summarizes and sorts out the researchs achievements on iteration

expansion and updating of synchronous phasor measurement algorithms

including the principles

accuracy

responsiveness

and applicability as well as adjustability of the synchronous fundamental

harmonic

and inter-harmonic phasor measurement algorithms. Simultaneously

we review the latest progress in optimizing the dynamic performance of the above algorithms under the complex power grid environment

which aims to achieve anti-interference capability

dynamic performance

and accuracy to meet the practical needs and relevant standards.
