Photovoltaic power plants are facilities that use solar energy to convert light energy into electrical energy, and are composed of multiple devices. Below is an introduction to the main equipment of photovoltaic power plants.

1、光伏組件

1. Photovoltaic modules

光伏組件是太陽能發(fā)電系統(tǒng)的核心和關(guān)鍵的部分，它的作用是將太陽能轉(zhuǎn)化為電能，并將其輸送到蓄電池中儲存，或者用于推動負(fù)載工作。

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

2、光伏逆變器

2. Photovoltaic inverter

逆變器是一種將光伏發(fā)電產(chǎn)生的直流電轉(zhuǎn)換為交流電的裝置。在光伏系統(tǒng)中，逆變器扮演著維持平衡的重要角色，可以與一般的交流供電設(shè)備配合使用。

An inverter is a device that converts 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、匯流箱

3. Combiner box

用戶可以將一定數(shù)量和規(guī)格相同的光伏電池串聯(lián)起來，形成光伏串列，然后將多個光伏串列并聯(lián)接入光伏匯流箱。在光伏匯流箱內(nèi)進(jìn)行匯流后，通過控制器、直流配電柜、光伏逆變器和交流配電柜的配套使用，構(gòu)建完整的光伏發(fā)電系統(tǒng)，并實現(xiàn)與市電的并網(wǎng)。

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

用于控制整個發(fā)電過程中的電流輸送，并保護(hù)設(shè)備等。

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

5、電纜

5. Cable

負(fù)責(zé)整個發(fā)電過程中的電流輸送工作。

Responsible for current transmission throughout the entire power generation process.

6、光伏儲能電池及器件

6. Photovoltaic energy storage batteries and devices

主要用于減少太陽能光伏發(fā)電系統(tǒng)對電力系統(tǒng)的影響，提高系統(tǒng)的穩(wěn)定性和可靠性。在光伏發(fā)電系統(tǒng)中，當(dāng)太陽能光伏發(fā)電系統(tǒng)產(chǎn)生的電能不足以滿足負(fù)載需求時，儲能電池可以及時將多余的電能儲存起來，以滿足負(fù)載的用電需求。同時，在太陽能光伏發(fā)電系統(tǒng)中，也會出現(xiàn)日照不足、夜間等情況，此時儲能電池可以為負(fù)載提供備用電源，避免負(fù)載因停電而停止工作。

Mainly used to reduce the impact of solar photovoltaic power generation systems on the power system, and improve the stability and reliability of the system. In photovoltaic power generation systems, 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 night time. At this time, energy storage batteries can provide backup power for the load to prevent it from stopping working due to power outages.

7、支架

7. Bracket

支架是安裝光伏電池板的設(shè)備。支架的設(shè)計要考慮太陽能的角度和方向，以便光伏電池板能夠大程度地接收太陽能。

The 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 a large extent.

8、升壓變壓器與箱式變電站

8. Step-up Transformer and Box Substation

雖然都是變電設(shè)備，但它們的結(jié)構(gòu)和用途不同。升壓變壓器主要用于提高電網(wǎng)的電壓質(zhì)量和容量，而箱式變電站主要用于減小電力系統(tǒng)中的電壓波動和電流突變，提高電力系統(tǒng)的供電可靠性和安全性。

Although they are all substation equipment, their structure and purpose 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、檢測裝置

9. Detection device

用于檢測光伏系統(tǒng)的性能和故障的設(shè)備。檢測裝置可以幫助維護(hù)人員及時發(fā)現(xiàn)和解決光伏系統(tǒng)中的問題，確保系統(tǒng)的穩(wěn)定性和可靠性。

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