Analysis on Lightning Overvoltage of 500kV Substation
Applied Mechanics and Materials, 2013The article used the ATP-EMTP to study over-voltage condition of each device and propose the corresponding measures to limit over-voltage in a safe range, to ensure the security of the system and stable operation. The article has great means to the actual analysis of lighting disturbance.

Study on transferred lightning overvoltage in microgrid
2010 Asia-Pacific International Symposium on Electromagnetic Compatibility, 2010If the microgrid is stroke by lightning, the lightning overvoltage which transferred though distribution transformer has great influence on the safety of the microgrid. The models of microgrid and high-frequency transformers are established based on the electromagnetic transient calculation program PSCAD/EMTDC.

Analyzing the Effect of Lightning Channel Impedance on the Induced Overvoltages in Wind Turbines
2022 IEEE International Conference on Environment and Electrical Engineering and 2022 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2022Lightning is a natural phenomenon that can cause serious damages in power systems including wind farms. Wind Turbines (WTs) are tall structures and are often installed in areas with high lightning activity levels which makes them exposed to direct strike.

A Study on Overvoltages in Windfarm Caused by Direct Lightning Stroke
IEEE Transactions on Power Delivery, 2019Wind turbine generators in a windfarm are connected by underground cables. Lightning sometimes strikes a nacelle or a blade. Lightning overvoltages due to a direct lightning strike to the system cause damages in the underground cable.
