Generation Analysis of Water Filling Data of Diversion Tunnel Based on GANs

To solve the problem of insufficient sample size during statistical analysis and modeling, this paper conducts experimental research using light Generative Adversarial Networks (GANs) based on finite sparse samples, against the problems in hydraulic engineering site such as poor operation environment, high damage rate of monitoring instruments, no timely real-time analysis and no large computing and analysis instruments. A light GANs model is built to realize fast filling of engineering field data by using laptop, based on the optimization of generator and discriminant network structure and the activation function. Compared with the time series prediction method, the KL divergence and Wasserstein distance analysis can reduce the distance between generated data and original data up to 33.3% in probability distribution. Research indicates that the proposed method is suitable for convenient and efficient filling of field water hammer data and able to solve the problem of insufficient sample size. It provides an effective solution for the future application of large sample modeling analysis and the overall characteristics analysis of measured data, which is of great significance to further popularize the application of artificial intelligence in water conservancy projects.
