光伏发电分为分布式与集中式，它们都是将太阳能转换为电能送到电网，所使用的主要设备也基本一致，只是分布式通常建筑物屋顶，工厂屋顶和蔬菜棚之类的地方，集中式在沙漠和戈壁等地区。

Photovoltaic power generation can be divided into distributed and centralized modes, both of which convert solar energy into electricity and send it to the grid. The main equipment used is also basically the same, except that distributed modes are usually found on the roofs of buildings, factories, and vegetable sheds, while centralized modes are found in areas such as deserts and Gobi.

　　那么除了安装的位置不同，还有什么区别吗？

So besides the different installation locations, are there any other differences?

　　区别还是有的，主要有3点：

There are still differences, mainly in three points:

　　1、传输距离

1. Transmission distance

　　分布式光伏发电一般发的电就地并网，补充当地电力，以供当地和附近的用电者使用，线损非常低。

Distributed photovoltaic power generation generally generates electricity that is locally connected to the grid, supplementing local electricity for use by local and nearby consumers, with very low line losses.

　　集中式光伏发电站产生的电力通过高压并网，将电力一层一层传送到更高的电压等级，再将高压电力传输到东部地区，实现西电东输。

The electricity generated by centralized photovoltaic power plants is connected to the grid through high voltage, transmitting the electricity layer by layer to higher voltage levels, and then transmitting the high voltage electricity to the eastern region, achieving the transmission of electricity from west to east.

　　2、并网电压等级

2. Grid connected voltage level

　　分布式光伏，通常使用低压脱扣器并网，分布式并网点的数量取决于实际情况。

Distributed photovoltaics typically use low-voltage releases for grid connection, and the number of distributed grid connection points depends on the actual situation.

　　3、使用的二次设备

3. Secondary equipment used

　　由于分布式光伏电站是低压并网设备，因此较少用于一次设备和二次设备。其中，逆变器通常是壁挂式逆变器，安装比较简单，尺寸较小。变压器也是那种小型变压器。常用的微机保护包括电能质量监控，防孤岛保护装置和故障解列。

Due to the fact that distributed photovoltaic power stations are low-voltage grid connected equipment, they are less commonly used for primary and secondary equipment. Among them, inverters are usually wall mounted inverters, which are relatively easy to install and have a smaller size. Transformers are also the type of small transformers. The commonly used microcomputer protection includes power quality monitoring, anti islanding protection devices, and fault isolation.

　　集中式光伏电站因为电压等级比较高，一般有自己的变电站。升压站内的设备比较多，一次设备有站用变、开关柜、各种互感器、消弧线圈、主变等。二次设备有微机保护、电度表、调度数据屏等。

Centralized photovoltaic power stations usually have their own substations due to their high voltage levels. There are many equipment in the booster station, including station transformers, switchgear, various transformers, arc suppression coils, main transformers, etc. Secondary equipment includes microcomputer protection, electricity meter, dispatch data screen, etc.

　　现在国家政策支持分布式光伏发电，分布式光伏装置的处在人员较多的地方，维护也更加方便。

Nowadays, national policies support distributed photovoltaic power generation, and distributed photovoltaic devices are located in areas with more personnel, making maintenance more convenient.
