3D Model Simulation Analysis at the end of Large Hydrogenerator Stator Bar-Based on COMSOL Multiphysics Platform

Abstract

This article applies COMSOL Multiphysics simulation platform developed by Sweden COMSOL company to perform 3D model simulation at the end of large hydrogenerator stator bar. Taking Pubugou Hydropower station as the prototype model, it introduces the parameters selected in geometric model, elaborates the detailed process in establishing the 3D model of the end of stator bar, introduces the specific process of material parameter selection and the mesh subdivision of stator bars, conducts the simulation and analysis of the anti-corona layer in the electric field, and then draws relevant conclusions.
