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電系統的核心和關鍵的部分，它的作用是將太陽能轉化為電能，并將其輸送到蓄電池中儲存，或者用于推動負載工作。

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電產生的直流電轉換為交流電的裝置。在光伏系統中，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

用戶可以將一定數量和規格相同的光伏電池串聯起來，形成光伏串列，然后將多個光伏串列并聯接入光伏匯流箱。在光伏匯流箱內進行匯流后，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，構建完整的光伏發電系統，并實現與市電的并網。

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

用于控制整個發電過程中的電流輸送，并保護設備等。

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

5、電纜

5. Cable

負責整個發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電系統對電力系統的影響，提高系統的穩定性和可靠性。在光伏發電系統中，當太陽能光伏發電系統產生的電能不足以滿足負載需求時，儲能電池可以及時將多余的電能儲存起來，以滿足負載的用電需求。同時，在太陽能光伏發電系統中，也會出現日照不足、夜間等情況，此時儲能電池可以為負載提供備用電源，避免負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備。支架的設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

雖然都是變電設備，但它們的結構和用途不同。升壓變壓器主要用于提高電網的電壓質量和容量，而箱式變電站主要用于減小電力系統中的電壓波動和電流突變，提高電力系統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

用于檢測光伏系統的性能和故障的設備。檢測裝置可以幫助維護人員及時發現和解決光伏系統中的問題，確保系統的穩定性和可靠性。

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.
