Lightning risk assessment of power systems

The work presented in this paper is a result of efforts to develop technically high-interest materials on lightning risk analysis aimed at teaching power systems. The paper describes series of case studies involving lightning effects on various parts of a power system including substations, transmission lines, and wind turbine systems. First, the paper defines the problem confronting protection systems engineers, reviews and investigates the protection systems conventionally used. Besides offering explanations of major concepts and models, the case studies utilize the graphical environment of MATLAB/SIMULINK and KADFEKO to help create visual representations for key design concepts concerning lightning protection systems.
