Lightning protection system for photovoltaic power station and photovoltaic power station

Abstract

Embodiments of the present invention disclose a lightning protection system for a photovoltaic power station and a photovoltaic power station. The photovoltaic power station includes a photovoltaic array, the photovoltaic array includes a plurality of photovoltaic components, and the lightning protection system includes: a lightning rod array, and the lightning rod array includes a plurality of lightning rods, a plurality of lightning rods Set on the photovoltaic array, the maximum distance between adjacent lightning rods is the first spacing; the balls are placed on adjacent and equal height lightning rods, the first spacing and the radius of the rolling balls and the penetration of the rolling balls relative to the corresponding lightning rods Depth is related, the radius of the rolling ball is related to the lightning protection level of the photovoltaic power station, and the penetration depth is less than or equal to the length of the corresponding lightning rod. The technical solutions provided by the embodiments of the present invention can solve the problem that only one lightning rod is used for the entire photovoltaic power station, resulting in a small lightning protection range, can effectively reduce the number of lightning rods, reduce the cost of photovoltaic power stations, and increase direct lightning strikes for frameless double-glass photovoltaic modules. protective function.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of lightning protection, and in particular, to a lightning protection system of 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 due to its characteristics of cleanliness, safety, extensiveness and resource adequacy. [0003] At present, most photovoltaic power plants are ground photovoltaic power plants and distributed photovoltaic power plants. The lightning protection measures used for these two photovoltaic power plants are to directly use the frame of photovoltaic modules as lightning arresters for lightning protection or to use a common one for all photovoltaic modules. The lightning protection measures of the lightning rod lead to problems such as small lightning protection area of ​​photovoltaic modules and poor lightning protection effect. Face...

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
