分布式光伏发电也称为分散发电或分布式能源供应。其特点是在用户现场或现场附近配置较小的光伏电源系统，以满足特定用户的需求，并支持现有配电网运行的经济性，或同时满足这两个要求。下面天合光能来讲讲光伏发电市场中的三种常见发电系统。

Distributed photovoltaic power generation is also called distributed power generation or distributed energy supply. It is characterized by the configuration of smaller photovoltaic power supply systems at or near the user site to meet the needs of specific users and support the economy of the existing distribution network operation, or both. Next, Trina Solar will talk about three common power generation systems in the photovoltaic power generation market.

1、一种独立的光伏发电系统，主要由太阳能电池组件，控制器和蓄电池组成。为了向交流负载供电，还需要交流逆变器。独立的光伏电站包括偏远地区村庄的电源系统，太阳能家用电源系统，通信信号电源，阴极保护，太阳能路灯以及其他带有电池的独立光伏发电系统。

1. An independent photovoltaic power generation system, mainly composed of solar cell modules, controllers and batteries. In order to supply power to AC load, AC inverter is also required. The independent photovoltaic power station includes the power supply system of villages in remote areas, solar household power supply system, communication signal power supply, cathodic protection, solar street lamps and other independent photovoltaic power generation systems with batteries.

2、并网光伏发电，并网光伏发电就是太阳能组件产生的直流电经过并网逆变器转换成符合市电电网要求的交流电之后直接接入公共电网，又分为带蓄电池的和不带蓄电池的并网发电系统，带有蓄电池的并网发电系统具有可调度性，可以根据需要并入或退出电网，还具有备用电源的功能，当电网因故停电时可紧急供电。

2. Grid connected photovoltaic power generation. Grid connected photovoltaic power generation means that the direct current generated by the solar modules is directly connected to the public grid after being converted into alternating current meeting the requirements of the municipal power grid through the grid connected inverter. It is also divided into grid connected power generation systems with and without batteries. The grid connected power generation system with a storage tank is schedulable, can be connected to or removed from the grid as required, and has the function of standby power supply, Emergency power supply can be provided when the power grid is cut off for some reason.

带有蓄电池的光伏并网发电系统常常安装在居民建筑；不带蓄电池的并网发电系统不具备可调度性和备用电源的功能，一般安装在较大型的系统上。

PV grid connected power generation system with battery is often installed in residential buildings; The grid connected power generation system without battery does not have the functions of schedulability and standby power supply, and is generally installed on a larger system.

3.构成部件主要由光伏电池组件、光伏方阵支架、直流汇流箱、直流配电柜、并网逆变器、交流配电柜等设备，另外还有供电系统监控装置和环境监测装置。其工作方式是在太阳辐射的条件下，光伏发电系统的太阳能电池模块阵列将太阳能输出的电能转化为电能，并通过直流汇流箱送至直流配电柜，并经逆变通过并网逆变器连接到交流电源通过连接到电网来调节建筑物自身的负载，剩余功率或不足功率。

3. Components mainly include photovoltaic cell modules, photovoltaic array supports, DC combiner boxes, DC distribution cabinets, grid connected inverters, AC distribution cabinets and other equipment, as well as power supply system monitoring devices and environmental monitoring devices. Its working mode is that under the condition of solar radiation, the solar cell module array of the photovoltaic power generation system converts the electrical energy output by solar energy into electrical energy, which is sent to the DC distribution cabinet through the DC combiner box, and is connected to the AC power supply through the grid connected inverter through the inverter to adjust the building's own load, residual power or insufficient power through connection to the grid.
