| Abstract | One of the most key factors affecting the safe and reliable operation of a wind farm is the damage of wind turbine blades suffered lightning strikes. In this study, the electric geometrical model of wind turbine blade (EGMWB) was presented based on the combination of the electrical geometry method and the physical process of the lightning leader. The simulation of the development process of a lightning leader is based on the introduction of the concept and analysis method of dynamic striking distance. Moreover, the method of calculating the efficiency of blade lightning protection system (LPS) was deduced. The influence of blade angle, lightning current amplitude and the arrangement of the lightning arrester on the blade LPS efficiency is analysed based on the EGMWB. Analysis indicates that the efficiency of blade LPS reduces with the decrease of lightning current and the angle between the blade and horizontal, and the efficiency of blade LPS can be improved by increasing the side lightning receptors. The EGMWB provides a theoretical basis for lightning protection design and evaluation of wind turbine blades. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
