Time synchronized phasor measurement
- รายละเอียด
P847 PMU
Time synchronized phasor measurement (i.e. synchrophasors) involves measuring electric system frequencies and phase angles very precisely from 20-120 times every second at various points across the electrical grid over large geographic areas. Synchrophasor measurements are time stamped using very precise time sources such as the Global Positioning Systems (GPS) satellite signals. This provides very detailed and precise time synchronized measurements of the state of the electrical grid.
