摘要:
Performing power quality and synchrophasor analysis on a resampled signal. A first signal may be initially received which corresponds to a power system. The first signal may have a plurality of cycles and may have a frequency that varies over time. One or more parameters may be determined from the first signal. Based on the one or more parameters, the first signal may be resampled to produce an even angle signal. Various power quality measurements may be performed on the even angle signal. Similarly, further processing may be performed to perform synchrophasor measurements, e.g., to determine phasor, frequency, and/or rate of frequency change for the first signal. In some embodiments, the resampling processing elements (e.g., circuitry, programmable hardware elements, processors and memories, etc.) may be shared between the two analysis.
