气温日渐升高，夏季的步伐一点点接近，在夏季是很多恶劣天气的爆发季节，其中非常常见的就是雷电天气，今天咱们就详细介绍—下雷击对分布式光伏发电项目的影响以及预防的措施。

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.

对于屋顶光伏电站来说，雷击不仅使光伏组件和逆变器造成毁坏，而且会造成电网整个系统的瘫痪。因为光伏组件和逆变器在前期投资占的比例较大，一旦遭受电击，组件发电功率降低，总发电量就会减少，逆变器可能损坏，增加了后期维护的费用。不仅影响电站业主的经济收益，更可能危害到屋顶电站下人身安全。

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.

如何应对雷击伤害?

How to deal with lightning strike injuries?

1、要做好防雷工作。雷电对光伏电站造成的影响分为两种，分别为“直击雷”和“感应雷”。正如其名称，直击雷是指光伏发电系统直接遭到雷击;感应雷是指附近遭到雷击时，雷击产生的电能经由光伏发电系统内的输电线及接地电线等传导，对发电设备施加远远超过额定水平的电压，从而对设备造成损伤。

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、由于控制器和逆变器均为价格昂贵的设备，应在控制器和逆变器内安装第2级的电源浪涌保护器，使其具有防雷保护功能.

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、在现阶段防雷措施中，最为有效也是最为广泛的方法就是把电气设备金属部件与大地相连。接地系统由四部分组成，即接地设备、接地体、引入线和大地。良好接地是防雷措施成功的重要基础。

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.
