一、太陽(yáng)跟蹤系統(tǒng)原理
視日運(yùn)動(dòng)軌跡跟蹤。由于相對(duì)于某一個(gè)固定地點(diǎn)的太陽(yáng)能光伏發(fā)電系統(tǒng),一年春夏秋冬四季、每天日升日落,太陽(yáng)的光照角度時(shí)時(shí)刻刻都在變化,如果太陽(yáng)能電池板能夠時(shí)刻正對(duì)太陽(yáng),發(fā)電效率才會(huì)達(dá)到最佳狀態(tài)。目前通用的太陽(yáng)跟蹤控制系統(tǒng)都需要根據(jù)安放點(diǎn)的經(jīng)緯度等信息計(jì)算一年中的每一天的不同時(shí)刻太陽(yáng)所在的角度,將一年中每個(gè)時(shí)刻的太陽(yáng)位置存儲(chǔ)到PLC中,也就是靠計(jì)算太陽(yáng)位置以實(shí)現(xiàn)跟蹤。
傳感器跟蹤。傳感器跟蹤是利用光線傳感器檢測(cè)太陽(yáng)光線是否偏離電池板基線,當(dāng)太陽(yáng)光線偏離電池板基線時(shí),傳感器輸出一個(gè)偏差信號(hào),該信號(hào)經(jīng)放大并轉(zhuǎn)成標(biāo)準(zhǔn)信號(hào),通過(guò)模擬量輸入通道傳給PLC,PLC運(yùn)算后通過(guò)開(kāi)關(guān)量輸出控制執(zhí)行機(jī)構(gòu),使跟蹤裝置重新對(duì)準(zhǔn)太陽(yáng)。
二、太陽(yáng)能電池方陣組網(wǎng)介紹
1、單個(gè)太陽(yáng)能電池方陣組網(wǎng)示意圖:反映某分類能耗(例如電)當(dāng)日及昨日同期、當(dāng)月及上月同期、當(dāng)年及上年同期的用能及對(duì)比,增長(zhǎng)百分比及增加值;
反映某分類能耗過(guò)去48小時(shí)、過(guò)去31天、過(guò)去12個(gè)月、過(guò)去3年的用能趨勢(shì);
