一、太陽跟蹤系統(tǒng)原理
視日運(yùn)動軌跡跟蹤。由于相對于某一個(gè)固定地點(diǎn)的太陽能光伏發(fā)電系統(tǒng),一年春夏秋冬四季、每天日升日落,太陽的光照角度時(shí)時(shí)刻刻都在變化,如果太陽能電池板能夠時(shí)刻正對太陽,發(fā)電效率才會達(dá)到最佳狀態(tài)。目前通用的太陽跟蹤控制系統(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)刻太陽所在的角度,將一年中每個(gè)時(shí)刻的太陽位置存儲到PLC中,也就是靠計(jì)算太陽位置以實(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太陽光線是否偏離電池板基線,當(dāng)太陽光線偏離電池板基線時(shí),傳感器輸出一個(gè)偏差信號,該信號經(jīng)放大并轉(zhuǎn)成標(biāo)準(zhǔn)信號,通過模擬量輸入通道傳給PLC,PLC運(yùn)算后通過開關(guān)量輸出控制執(zhí)行機(jī)構(gòu),使跟蹤裝置重新對準(zhǔn)太陽。
二、太陽能電池方陣組網(wǎng)介紹
1、單個(gè)太陽能電池方陣組網(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比,增長百分比及增加值;
反映某分類能耗過去48小時(shí)、過去31天、過去12個(gè)月、過去3年的用能趨勢;
反映某分項(xiàng)能耗的當(dāng)月用能餅圖;
反映某分類能耗當(dāng)年各月用能同比分析圖;
c.分類能耗支路用能統(tǒng)計(jì)報(bào)表

可靈活選擇支路,并統(tǒng)計(jì)某段時(shí)間內(nèi)支路用能的日、月、周、季、年用能;
通過透視表功能強(qiáng)大,用戶可進(jìn)行多種數(shù)據(jù)統(tǒng)計(jì),并對數(shù)據(jù)進(jìn)行組合排序;
統(tǒng)計(jì)數(shù)據(jù)可通過柱狀圖、點(diǎn)線圖、堆積圖、餅圖等多種圖表展示;
統(tǒng)計(jì)數(shù)據(jù)可導(dǎo)出至Excel;
