DATA ALIGNMENT IN LARGE SCALE ELECTRICAL SYSTEM APPLICATIONS |
摘要 |
A method for automatically aligning measured power-related data in a power monitoring system to a common reference point. A conductor in a power delivery system is modeled according to an equivalent pi model of a transmission line that is characterized by model parameters. The conductor is monitored on both ends by a reference monitoring device and a second monitoring device. The voltage and current are measured in either the reference monitoring device or the second monitoring device and a phase shift offset between the voltages or currents at the two devices is calculated. The calculated phase shift offset corresponds to a temporal delay between events observed at the pair of devices, and calculating and storing the phase shift offset allows a power monitoring system controller to more accurately align data received from monitoring devices.
