Abstract: |
With GPS and crystal,a highly precise and consistent clock system is established in the real time phasor measurement system to overcome GPS's clock discreteness and probable deadlock.It ensures the accuracy of phasor measurement for each real time phasor measurement unit.Its measuring principle and structure are presented.The applications of real time phasor are prospected in centralized monitoring,state estimation,FACTS and stability control of power system. |
Key words: GPS,real time phasor measurement unit,transient stability |
