Abstract
Measurement of power system phase angle is being studied for use in protective relaying, critical control circuits, and other applications. This paper compares phase angles measured by a synchronized measuring unit during field testing with classical theory. Power system positive sequence voltage and current phasors were recorded during testing of a new 525 kV compensated transmission system. Steady-state phase angles (/spl delta/) and magnitudes were measured relative to a satellite-based global time standard on synchronized measurement units at two substations. Phase angles were calculated using a recorded supervisory system and sending-end values of total power flow. Field measurements of the phase angle across a transmission system differed from calculations by -0.09/spl deg/ on average, contributing to verification of the new synchronized measurement technique.
