並網發電係統詳解
Detailed explanation of grid connected power generation system
太陽能發電並網係統安裝
一、太陽能發電並網係統基本配件:
、 Basic accessories of grid connected system:

對於並網發電係統來說,並網發電係統有幾個優點:一是效率高,整體效率最高可達80-90%左右;二是成本低。與離網係統相比,省去了電池和控製器,造價降低了1/3以上。三是負荷能力不夠的問題。並網係統的組成部分是什麽?如上所述,與離網係統相比,節省了電池和控製器。也就是說,並網係統最基本的就是太陽能電池板和並網逆變器。其他為相關附件,如空氣開關、斷路器、避雷器、電流表等。
For the grid connected power generation system, the grid connected power generation system has several advantages: first, the efficiency is high, the overall efficiency can reach 80-90%; second, the cost is low. Compared with the off grid system, the battery and controller are omitted, and the cost is reduced by more than 1 / 3. Third, the problem of insufficient load capacity. What are the components of the grid connected system? As mentioned above, compared with the off grid system, the battery and controller are saved. In other words, the most basic grid connected system is solar panels and grid connected inverter. Others are related accessories, such as air switch, circuit breaker, arrester, ammeter, etc.

二、太陽能發電並網係統應注意的問題
、 Problems in grid connected system

並網係統與離網係統最大的區別在於,並網係統依靠市電或其他電源。並網發電與市政潮流相結合,不存在波型不好、電壓不穩定、負荷能力弱、陰雨天無法使用等問題。但有一件事皇冠AG真人必須注意。也就是說,如果並網係統離開城市供電或其他引導電源,它將被孤島保護並停止工作。為什麽要這樣設計?原因很簡單。例如,如果你家附近的供電線路有問題,供電局會來修理的。出於安全考慮,可能需要切斷電源。斷電後,如果家裏的逆變器不停止工作,它仍然會向外界輸出電流。這很危險。如果維修人員在不知情的情況下操作,很可能會導致死亡!當然,我隻是打了個比方。實際情況可能比這更嚴重!
The biggest difference between grid connected system and off grid system is that grid connected system relies on municipal power or other power sources. When the grid connected power generation is combined with the municipal power flow, there are no problems such as bad wave pattern, unstable voltage, weak load capacity and unable to be used in rainy days. But there is one thing we have to pay attention to. In other words, if the grid connected system leaves the urban power supply or other guiding power supply, it will be Island protected and stop working. Why design like this? The reason is simple. For example, if there is a problem with the power supply line near your home, the power supply bureau will come to repair it. For safety reasons, it may be necessary to cut off the power supply. After power failure, if the home inverter does not stop working, it will still output current to the outside world. It's dangerous. If the maintenance personnel operate without knowing it, it may lead to death! Of course, I'm just making an analogy. The actual situation may be more serious than this!

三、太陽能發電並網基本條件
三、Basic conditions for grid connection

上麵說了一些關於電網連接的事情。現在皇冠AG真人來談談並網的先決條件。最基本的是向供電局申請。現在國家還鼓勵個人投資分布式並網發電項目。他們可以根據當地的政策得到相應的補貼或優惠政策。如果供電局同意連接,你可以自由使用,而不受發電量的限製。
第二,私網連接,我想強調一下,私網的並網問題有幾個方麵需要注意,首先是發電的問題,因為並網發電是與城市電力相結合的,所有發電都是在白天送出的。如果你接通了電網,但是你白天不用電,那麽你的電能會通過你家的電表回到電網,如果你沒有得到供電局的許可,也沒有安裝雙向或獨立的計量表,那麽你送的電就會白白送到供電局,送出的電會按照你現在的電價再交一次電費。這是一件非常值得的事!所以,如果你想私下上網,就必須計算出一天內你有多少負荷和能用多少電,然後再計算出板的大小,也就是說。如果你的負載是1000瓦。配電盤的功率不得大於1000W,以便配電盤產生的電能。會直接被你的負荷消耗掉,不會返回電網,保證你可以自發地使用它,不會造成浪費!
There's something about the grid connection. Now let's talk about the prerequisites for grid connection. The most basic is to apply to the power supply bureau. Now the state also encourages individuals to invest in distributed grid connected power generation projects. They can get corresponding subsidies or preferential policies according to local policies. If the power supply bureau agrees to connect, you can use it freely without being limited by the amount of electricity generated.

Second, private grid connection. I would like to emphasize that there are several aspects to be paid attention to in the connection of private grid. The first is power generation, because grid connected power generation is combined with urban power, and all power generation is delivered in the daytime. If you are connected to the power grid, but you do not use electricity during the day, then your electricity will be returned to the grid through your home meter. If you do not get the permission of the power supply bureau and do not install two-way or independent meters, then the electricity you send will be sent to the Power Supply Bureau in vain, and the electricity will be paid again according to your current price. This is a very worthwhile thing! So if you want to go online in private, you have to figure out how much load you have and how much power you can use in a day, and then you can figure out the size of the board, that is to say. If your load is 1000 watts. The power of the switchboard shall not be greater than 1000W in order to generate energy from the switchboard. Will be directly consumed by your load, will not return to the grid, to ensure that you can use it spontaneously, will not cause waste!
