| Outline of Final Research Achievements |
New method for the prediction of upward lightning flash from a windmill and its protection tower is developed using the electric field mapping technique considering the electric field caused by the space charge above the ground. This method is also tested with measurement data of electric field and space charge density at multiple sites around the windmill. The tested result shows that it is possible to predict the upward lightning flash from the windmill and its protection tower at least 30 seconds before the discharge with over 50% occurrence probability for the self-triggered upward lightning and 30 seconds before the discharge with over 90% occurrence probability for the other-triggered upward lightning respectively.
