Reconstruction of Missing Measurement Data in Distribution Network Based on Generative Adversarial Network and Double Semantic Perception
Traditional data missing reconstruction technology mostly relies on mathematical statistics method and prior knowledge combined with mechanism analysis to construct mathematical models. However
measurement data in distribution network has high dimensional
time-variant
non-linear characteristics with high complexity and difficult characterization
and it is difficult to ensure high-precision reconstruction. In this paper
an unsupervised generation antagonism training method is proposed to extract data features autonomously and reconstruct missing data with reconstruction constraints of dual semantic perception. In the method
the reconstruction model based on two-dimensional convolution and the two-dimensional gray image training of measurement data enhance the generalization ability and stability of the model. This method does not need the distribution hypothesis of prior knowledge and explicit physical modeling
and it effectively improves the accuracy of reconstructed data while guaranteeing maximum feature extraction. Finally
the validity of this method in reconstructing missing data is verified by the field measured data.
