Phasor measurements, current measurements, State Estimation, snapshot data
This paper utilizes phasor measurements at busses of the power network into State Estimation programs without extensive re-coding the software. The advent of the Global Positioning System (GPS) absolute time reference allows voltage phase angles to be measured, then referred to a reference bus. Bus real power injections are updated between State Estimator iterations to satisfy phase measurements. The phasor measurement also allows line current measurements to be resolved into a real part proportional to real power. Up to this time current measurements were not used because they degrade convergence of the State Estimation algorithm.
