氣溫日漸升高，夏季的步伐一點(diǎn)點(diǎn)接近，在夏季是很多惡劣天氣的爆發(fā)季節(jié)，其中非常常見的就是雷電天氣，今天咱們就詳細(xì)介紹—下雷擊對(duì)分布式光伏發(fā)電項(xiàng)目的影響以及預(yù)防的措施。

The temperature is gradually rising, and the pace of summer is getting closer. Summer is a season of many severe weather events, among which lightning weather is very common. Today, we will introduce in detail the impact of lightning strikes on distributed photovoltaic power generation projects and preventive measures.

對(duì)于屋頂光伏電站來說，雷擊不僅使光伏組件和逆變器造成毀壞，而且會(huì)造成電網(wǎng)整個(gè)系統(tǒng)的癱瘓。因?yàn)楣夥M件和逆變器在前期投資占的比例較大，一旦遭受電擊，組件發(fā)電功率降低，總發(fā)電量就會(huì)減少，逆變器可能損壞，增加了后期維護(hù)的費(fèi)用。不僅影響電站業(yè)主的經(jīng)濟(jì)收益，更可能危害到屋頂電站下人身安全。

For rooftop photovoltaic power plants, lightning strikes not only cause damage to photovoltaic modules and inverters, but also result in the paralysis of the entire power grid system. Due to the large proportion of initial investment in photovoltaic modules and inverters, once they are subjected to electric shock, the power generation of the modules will decrease, and the total power generation will decrease. The inverter may be damaged, increasing the cost of maintenance in the later stage. Not only does it affect the economic benefits of power plant owners, but it may also pose a threat to the personal safety of people in rooftop power plants.

如何應(yīng)對(duì)雷擊傷害?

How to deal with lightning strike injuries?

1、要做好防雷工作。雷電對(duì)光伏電站造成的影響分為兩種，分別為“直擊雷”和“感應(yīng)雷”。正如其名稱，直擊雷是指光伏發(fā)電系統(tǒng)直接遭到雷擊;感應(yīng)雷是指附近遭到雷擊時(shí)，雷擊產(chǎn)生的電能經(jīng)由光伏發(fā)電系統(tǒng)內(nèi)的輸電線及接地電線等傳導(dǎo)，對(duì)發(fā)電設(shè)備施加遠(yuǎn)遠(yuǎn)超過額定水平的電壓，從而對(duì)設(shè)備造成損傷。

1. We need to do a good job in lightning protection. The impact of lightning on photovoltaic power plants can be divided into two types, namely "direct lightning" and "induced lightning". As its name suggests, direct lightning strike refers to a photovoltaic power generation system being directly struck by lightning; Induction lightning refers to the electrical energy generated by lightning strikes when nearby areas are struck, which is conducted through the transmission lines and grounding lines in the photovoltaic power generation system, and applies voltages far exceeding the rated level to the power generation equipment, causing damage to the equipment.

2、由于控制器和逆變器均為價(jià)格昂貴的設(shè)備，應(yīng)在控制器和逆變器內(nèi)安裝第2級(jí)的電源浪涌保護(hù)器，使其具有防雷保護(hù)功能.

2. Due to the high cost of both controllers and inverters, a second level power surge protector should be installed inside the controllers and inverters to provide lightning protection

3、在現(xiàn)階段防雷措施中，最為有效也是最為廣泛的方法就是把電氣設(shè)備金屬部件與大地相連。接地系統(tǒng)由四部分組成，即接地設(shè)備、接地體、引入線和大地。良好接地是防雷措施成功的重要基礎(chǔ)。

3. The most effective and widely used lightning protection measure at present is to connect the metal components of electrical equipment to the ground. The grounding system consists of four parts, namely grounding equipment, grounding body, incoming wire, and earth. Good grounding is an important foundation for successful lightning protection measures.
