Apparatus and method for estimating synchronized phasors at predetermined times referenced to a common time standard in an electrical system |
摘要 |
An apparatus and method estimates a plurality of synchronized phasors at predetermined times referenced to a common time standard in an electrical power system. The method includes acquiring and determining a frequency of a power system signal, sampling the power system signal at a sampling interval rate based on a frequency of the power system signal to form signal samples, and generating a plurality of acquisition time values based on an occurrence of each of the signal samples at a corresponding plurality of different times referenced to the common time standard. The method further includes adjusting a phasor of each of the signal samples based on a time difference between a corresponding selected acquisition time value and a predetermined time referenced to a common time standard to form the plurality of synchronized phasors.
