CPC G01R 23/02 (2013.01) [G01R 23/005 (2013.01); H03M 1/12 (2013.01)] | 20 Claims |
1. A system comprising:
a memory device; and
a processor operatively coupled to the memory device, wherein the processor is configured to execute instructions stored on the memory device to cause operations comprising:
obtaining a plurality of electrical values of an electrical waveform of an electric power delivery system, wherein the plurality of electrical values comprises:
a first value obtained at a first time; and
a plurality of previous values obtained at a plurality of times before the first time, wherein the plurality of previous values comprises a first previous value obtained at a second time;
determining a plurality of computed derivative values of the electrical waveform based on one or more of the plurality of previous values, wherein the plurality of computed derivative values comprises a first computed derivative value corresponding to a derivative of the first previous value;
determining, from the first computed derivative value, a first scaled derivative value that is scaled according to a first time duration between the second time and the first time;
determining a frequency of the electrical waveform based at least in part on the first time duration, the first value, and the first scaled derivative value; and
causing an operation of the electric power delivery system to be controlled based at least in part on the frequency.
