Research on Adaptive Harmonic Current Detection Method Based on Neural Network

Abstract

The application of a large number of non-linear loads in the power grid has caused
serious harmonic pollution, which has brought serious adverse effects to the safe and
efficient operation of the power grid system. However, there are many deficiencies in
the current commonly used power harmonic detection methods. Based on this, this
paper first studies the calculation of power grid harmonics and harmonics, and then
analyses the neural network model and its adaptive adjustment principle. Finally, the
adaptive harmonic current detection method based on neural network and the specific
implementation strategies are given.
