Summary: | The invention relates to an electrical quantity vector estimation method and device and a computer readable storage medium, and belongs to the technical field of electrical quantity estimation. Comprising the steps of obtaining electrical quantity vectors at the n moment and the n + 1 moment in a training set, preprocessing the electrical quantity vectors at the n moment, inputting the electrical quantity vectors into an adaptive filter, calculating an error between an electrical quantity vector estimated value at the n + 1 moment and the electrical quantity vector at the n + 1 moment, and if the error is greater than a preset error, determining that the electrical quantity vector is not the electrical quantity vector. Adjusting a weight vector, a leakage factor and a step length of the adaptive filter by using a steepest descent method, and updating n = n + 1; and if the error is less than or equal to the preset error, updating the sampling frequency of the adaptive filter, and taking the updated adaptive fi |
