Noncollocated voltage and current measurements used to obtain power

Brian Mann, G. Heydt

Research output: Contribution to journalArticlepeer-review


Voltage and current measurements are routinely used as inputs to transducers in order to obtain sensory information on active and reactive power. If the voltage and current measurements are not collocated, the power measurements will be incorrect. In this letter, a correction is calculated for noncollocated voltage and current measurements used to obtain power. The correction is obtained utilizing the noncollocated power and one voltage magnitude measurement. One application area is in state estimation sensory inputs.
