Computer simulation for lightning and overvoltage protection of wind power plants

This paper presents assumptions concerning the computer program LPS 2008 developed in Visual Basic by the authors. This program was specially designed for protection of wind power plants, but is enough general to be applied to other structures and services. The program runs over AutoCAD and performs risk assessment on a structure or on a service due to lightning flashes to earth. Our program is a three dimensional one and is based on the Rolling Sphere Method. LPS 2008 marks the vulnerable points on a structure, taking into account the most recent international standards.
