光伏发电站包含的设备有哪些？

What are the equipment included in a photovoltaic power station?

　　光伏电站是利用太阳能将光能转化为电能的设施，它由多个设备组成。下面为大家介绍光伏电站的主要设备。

A photovoltaic power station is a facility that converts solar energy into electrical energy, consisting of multiple devices. Below, we will introduce the main equipment of photovoltaic power stations.

　　1、光伏组件

1. Photovoltaic modules

　　光伏组件是太阳能发电系统的核心和最关键的部分，它的作用是将太阳能转化为电能，并将其输送到蓄电池中储存，或者用于推动负载工作。

Photovoltaic modules are the core and most critical part of solar power generation systems. Their function is to convert solar energy into electrical energy and transport it to batteries for storage, or to drive load operation.

　　2、光伏逆变器

2. Photovoltaic inverter

　　逆变器是一种将光伏发电产生的直流电转换为交流电的装置。在光伏系统中，逆变器扮演着维持平衡的重要角色，可以与一般的交流供电设备配合使用。

An inverter is a device that converts the direct current generated by photovoltaic power generation into alternating current. In photovoltaic systems, inverters play an important role in maintaining balance and can be used in conjunction with general AC power supply equipment.

　　3、汇流箱

3. Combiner box

　　用户可以将一定数量和规格相同的光伏电池串联起来，形成光伏串列，然后将多个光伏串列并联接入光伏汇流箱。在光伏汇流箱内进行汇流后，通过控制器、直流配电柜、光伏逆变器和交流配电柜的配套使用，构建完整的光伏发电系统，并实现与市电的并网。

Users can connect a certain number of photovoltaic cells with the same specifications in series to form a photovoltaic series, and then connect multiple photovoltaic series in parallel to the photovoltaic combiner box. After converging in the photovoltaic combiner box, a complete photovoltaic power generation system is constructed through the matching use of controllers, DC distribution cabinets, photovoltaic inverters, and AC distribution cabinets, and grid connection with the mains is achieved.

　　4、控制柜

4. Control cabinet

　　用于控制整个发电过程中的电流输送，并保护设备等。

Used to control the current transmission throughout the entire power generation process and protect equipment, etc.

　　5、电缆

5. Cable

　　负责整个发电过程中的电流输送工作。

Responsible for the current transmission throughout the entire power generation process.

　　6、光伏储能电池及器件

6. Photovoltaic energy storage cells and devices

　　主要用于减少太阳能光伏发电系统对电力系统的影响，提高系统的稳定性和可靠性。在光伏发电系统中，当太阳能光伏发电系统产生的电能不足以满足负载需求时，储能电池可以及时将多余的电能储存起来，以满足负载的用电需求。同时，在太阳能光伏发电系统中，也会出现日照不足、夜间等情况，此时储能电池可以为负载提供备用电源，避免负载因停电而停止工作。

Mainly used to reduce the impact of solar photovoltaic power generation systems on power systems, improve system stability and reliability. In the photovoltaic power generation system, when the electricity generated by the solar photovoltaic power generation system is insufficient to meet the load demand, the energy storage battery can timely store the excess electricity to meet the load's electricity demand. At the same time, in solar photovoltaic power generation systems, there may also be situations such as insufficient sunlight and nighttime. At this time, energy storage batteries can provide backup power for the load, avoiding the load from stopping working due to power outages.

　　7、支架

7. Support bracket

　　支架是安装光伏电池板的设备。支架的设计要考虑太阳能的角度和方向，以便光伏电池板能够最大程度地接收太阳能。

A bracket is a device for installing photovoltaic panels. The design of the bracket should consider the angle and direction of solar energy, so that the photovoltaic panel can receive solar energy to the maximum extent.

　　8、升压变压器与箱式变电站

8. Step-up transformers and box type substations

　　虽然都是变电设备，但它们的结构和用途不同。升压变压器主要用于提高电网的电压质量和容量，而箱式变电站主要用于减小电力系统中的电压波动和电流突变，提高电力系统的供电可靠性和安全性。

Although they are all substation equipment, their structures and uses are different. Step-up transformers are mainly used to improve the voltage quality and capacity of the power grid, while box type substations are mainly used to reduce voltage fluctuations and current mutations in the power system, improve the reliability and safety of power supply.

　　9、检测装置

9. Detection device

　　用于检测光伏系统的性能和故障的设备。检测装置可以帮助维护人员及时发现和解决光伏系统中的问题，确保系统的稳定性和可靠性。

Equipment used to detect the performance and faults of photovoltaic systems. The detection device can help maintenance personnel detect and solve problems in the photovoltaic system in a timely manner, ensuring the stability and reliability of the system.
