Monitoring of Lightning Strikes and Evaluation of Energy Inflow on Substation Equipment

Transmission system operators encounter new dimensions in their business operations in recent years. Huge sets of data are collected in control room and new functionalities are created for both real time and off line operations. Data from lighting detection system in control room will be used in a new way in next to real time manner. Transmission line outages caused by lightning strikes are recognized in precise manner and archived in real time. With detailed value of each lightning, it will be researched how much energy from the strike inflows to substation. Special security perimeter with three kilometers distance from substations will detect strikes. Those strikes, dangerous for equipment inside substation will be examined. Detail model of 110 kV line are modeled and various scenarios are conducted. This study work will give insights about amount of energy inflow to substation and give guidelines for making this process an automated procedure in the future. Results from this work will be used in maintenance business process in company.
