As a key physical process of the research about lightning protection of wind turbine blades, the inception mechanism and criterion of the upward leader need further investigation. A model of line charge with point charge at the head is used to simulate charge distribution of lightning downward leader. A curve about density of surface charges on blade is presented after considering the movement, diffusion...
The weather factors with on-site EMC measurement may differ a lot from the standard calibration condition, so it is necessary to analyze the impact of weather factors, such as temperature, humidity and atmosphere pressure, on the measurement accuracy of the antennas. Based on experimental study, digital signal processing, improved vector fitting methods and artificial neural networks (ANN), a comprehensive...
