分布式光伏發(fā)電的工作原理介紹
分布式光伏發(fā)電是指將太陽能光伏發(fā)電設備分布在用戶用電的地方,通過本地用電和余電回供的方式,理論上可以在一定程度上實現用戶的自給自足,或為電網提供電源。以下是分布式光伏發(fā)電的工作原理:
Distributed photovoltaic power generation refers to the distribution of solar photovoltaic power generation equipment in the areas where users use electricity. Through local electricity consumption and residual electricity supply, it can theoretically achieve user self-sufficiency to a certain extent or provide power to the grid. The following is the working principle of distributed photovoltaic power generation:
光伏組件吸收日光。光伏組件吸收來自太陽的能量,將太陽光轉化為電能。
Photovoltaic modules absorb sunlight. Photovoltaic modules absorb energy from the sun and convert sunlight into electrical energy.
直流電輸送。電能經過逆變器的變換作用轉化為直流電,然后經過電線輸送到矩陣電池中寄存。
Direct current transmission. The electrical energy is converted into direct current through the conversion effect of the inverter, and then transmitted through wires to the matrix battery for storage.
負荷就地供電。直流電再經過逆變器的處理,轉化為交流電,供應用戶使用,稱作就地供電。
Load local power supply. Direct current is then processed by an inverter and converted into alternating current, which is supplied to users for use, known as on-site power supply.
余電回饋。當直流電產生的能量大于用戶所消耗的能量時,多余的電能可以回饋到電網中,成為余電供電,即余電輸出。
Residual electricity feedback. When the energy generated by direct current is greater than the energy consumed by the user, the excess electrical energy can be fed back to the grid and become surplus power supply, that is, surplus power output.
綜合用電與余電回饋供電。用戶用電的產生往往呈不穩(wěn)定的特點,因此分布式光伏發(fā)電系統還可以通過綜合用電與余電回饋供電的方式,以滿足各種用電需求。
Comprehensive electricity consumption and surplus electricity feedback power supply. The generation of electricity consumption by users is often characterized by instability, so distributed photovoltaic power generation systems can also meet various electricity needs through comprehensive electricity consumption and residual electricity feedback power supply.
總之,分布式光伏發(fā)電是通過將太陽能光伏發(fā)電設備分布在用戶用電地方,實現就地供電和余電回饋供電的方式,可以在一定程度上實現用戶的自給自足,或為電網提供電源,實現節(jié)能減排的效果。
In short, distributed photovoltaic power generation is a method of distributing solar photovoltaic power generation equipment in the user's electricity consumption area, achieving on-site power supply and residual electricity feedback power supply, which can to some extent achieve user self-sufficiency or provide power to the grid, achieving energy-saving and emission reduction effects.
