Abstract
The substation is an important part of power system is the core of power transmission grid. Once the substation being struck by lightning, may directly cause the collapse of the grid, the city blackout, the security of social harmony and stability to the tremendous negative impact. Therefore, the requirements must be configured to secure substation lightning protection.
This 110kv substation lightning protection system design for conducting research and resolve a number of related issues, including the substation Zhiji main content protection, lightning protection, power distribution equipment protection, 110kv substation substation breaker selection of lightning protection and surge arresters substation to increase after the lightning protection measures microwave towers, power plants, substations and weak systems of lightning protection, substation building steel doors and windows, curtain wall of the mine technology, the main transformer neutral grounding protection device technology, integrated automation substation II lightning protection subsystem, electrolytic ion ground system transformation in the substation grounding grid design and calculation of the secondary system of protection, building protection, grounding technology, how to apply in engineering and in the application need to pay attention to what matters.
Keywords：substation ,lightning wave,lightning protection
