Lightning protection system of photovoltaic power station and photovoltaic power station

Abstract

The embodiment of the invention discloses a lightning protection system of a photovoltaic power station and the photovoltaic power station. The photovoltaic power station comprises a photovoltaic array, the photovoltaic array comprises a plurality of photovoltaic assemblies, the lightning protection system comprises a lightning rod array, the lightning rod array comprises a plurality of lightningrods, the plurality of lightning rods are arranged on the photovoltaic array, and the maximum distance between the adjacent lightning rods is a first distance; the rolling balls are placed on adjacentlightning rods with the same height, the first interval is related to the radius of the rolling balls and the penetration depth of the rolling balls relative to the corresponding lightning rods, theradius of the rolling balls is related to the lightning protection level of the photovoltaic power station, and the penetration depth is smaller than or equal to the length of the corresponding lightning rods. According to the technical scheme provided by the embodiment of the invention, the problem that the lightning protection range is small due to the fact that only one lightning rod is used inthe whole photovoltaic power station can be solved, the number of the lightning rods can be effectively reduced, the cost of the photovoltaic power station is reduced, and a direct lightning protection function is added to the frameless double-glass photovoltaic module.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of lightning protection, and in particular to a lightning protection system for a photovoltaic power station and a photovoltaic power station. Background technique [0002] Photovoltaic power generation plays an important role in the long-term energy strategy because of its cleanness, safety, extensiveness and resource adequacy. [0003] At present, most of the photovoltaic power stations are ground photovoltaic power stations and distributed photovoltaic power stations. The lightning protection measures used for these two photovoltaic power stations are to directly use the frame of the photovoltaic module as a lightning protection device or use a common one for all photovoltaic modules The lightning protection measures of lightning rods lead to problems such as small lightning protection area of ​​photovoltaic modules and poor lightning protection effect. Facing the shortage of land s...

AI Technical Summary

Problems solved by technology

However, surface photovoltaic power stations mostly use frameless double-glass modules as photovoltaic modules, which cannot effectively ground photovoltaic modules, resulting in frequent lightning strikes for water surface photovoltaic power stations, especially ineffective protection against direct lightning strikes
