Embodiment Construction
[0044] A method for processing power grid harmonic distortion, comprising the steps of:
[0045] Step 1: Data Entry
[0046] There are n charging piles, and the signal of each power system is collected, and the voltage u, frequency f and initial phase ω of the power signal are used as parameters to construct a matrix
[0047]
[0048] The power signals collected at different times are recorded separately, so for time i, there is
[0049]
[0050] The acquisition signal takes the moment when any charging pile has a state change as time 0, and the acquisition signal is carried out continuously, and the sampling frequency is 100-10000 times of the fundamental frequency.
[0051] The state change of any charging pile means that the state of any charging pile changes from "not charging" to "charging", or from "charging" to "not charging".
[0052] Step 2: Fetch valid data
[0053] When the number of samples is less than kn, continue sampling without processing; when the sa...
