Abstract

At present, the lightning protection structure of photovoltaic power station buildings is mostly a one-way structure. The lightning protection area is not fixed, which leads to an increase in impulse grounding resistance. Therefore, the analysis and verification of the lightning protection design of the photovoltaic power station building are proposed. Based on the actual measurement requirements and standards, the vulnerable parts of the photovoltaic power station are calibrated first. The lightning induction points are set. On this basis, the multi-objective form is adopted to define the specific lightning protection area inside the building. The multi-objective lightning dynamic protection structure is constructed, and the grounding treatment is used to realize the lightning protection of the power station building. The final test results indicate that the impulse grounding resistance decreases gradually with the expansion of the protection area, which verifies that the lightning protection effect has been improved. Besides, the lightning protection structure is more controllable, which has practical application value.
