An automatic mesh generator for handling small features in open boundary power transmission line problems using artificial neural networks

An artificial neural network (ANN) has been trained to automatically predict the mesh density vector of open-boundary faulted power transmission line problems under the presence of small features, such as conductors. In order to produce the data for the training database of the ANN a technique for recursively subdividing the solving area is proposed. A Delaunay-based mesh generator is used to produce the final mesh. Several test cases show that the proposed automatic mesh generator significantly reduces solving time.
