電力系統

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力系(xi)(xi)(xi)統(tong)是(shi)由發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)廠、送變電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線路(lu)、供配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)所和用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)等(deng)環(huan)節組成的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)生產(chan)與消(xiao)費(fei)系(xi)(xi)(xi)統(tong)。它的功能(neng)(neng)是(shi)將自然界(jie)的壹次(ci)能(neng)(neng)源通過發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動力裝(zhuang)置轉化成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)，再經輸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)、變電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)和配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)供應到各用戶。為(wei)實(shi)現這壹功能(neng)(neng)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力系(xi)(xi)(xi)統(tong)在各個環(huan)節和不(bu)同層次(ci)還具有(you)相(xiang)應的信(xin)息與控制(zhi)系(xi)(xi)(xi)統(tong)，對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)的生產(chan)過程(cheng)進(jin)行(xing)測量、調節、控制(zhi)、保護(hu)、通信(xin)和調度，以保證(zheng)用戶獲得安全、優質的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)。

電(dian)(dian)(dian)(dian)力系統的(de)主(zhu)體結構有電(dian)(dian)(dian)(dian)源（水電(dian)(dian)(dian)(dian)站、火電(dian)(dian)(dian)(dian)廠、核電(dian)(dian)(dian)(dian)站等發電(dian)(dian)(dian)(dian)廠），變(bian)電(dian)(dian)(dian)(dian)所(suo)（升壓變(bian)電(dian)(dian)(dian)(dian)所(suo)、負(fu)荷中心變(bian)電(dian)(dian)(dian)(dian)所(suo)等），輸(shu)(shu)電(dian)(dian)(dian)(dian)、配電(dian)(dian)(dian)(dian)線(xian)路和(he)(he)負(fu)荷中心。各電(dian)(dian)(dian)(dian)源點還互相聯接以實現不同(tong)地區之間的(de)電(dian)(dian)(dian)(dian)能(neng)交換和(he)(he)調節，從而提(ti)高供電(dian)(dian)(dian)(dian)的(de)安全性和(he)(he)經濟性。輸(shu)(shu)電(dian)(dian)(dian)(dian)線(xian)路與(yu)變(bian)電(dian)(dian)(dian)(dian)所(suo)構成的(de)網(wang)絡通(tong)常稱電(dian)(dian)(dian)(dian)力網(wang)絡。

建築電氣

隨著經濟的(de)發展，城市(shi)建(jian)設日新(xin)月異，現代建(jian)築內部辦公專業設施齊全(quan)，自動化程度高，為了保證現代建(jian)築電氣(qi)整(zheng)體運行的(de)可(ke)靠性、安(an)全(quan)性及(ji)智能化設備的(de)先進性，電氣(qi)工程中的(de)強、弱電系統安(an)裝方法和安(an)裝質量至關(guan)重要。

工業控制系統

隨著(zhu)企(qi)業(ye)(ye)信息(xi)網(wang)絡(luo)的深入應用與日臻完善，現場(chang)控(kong)制信息(xi)進入信息(xi)網(wang)絡(luo)實(shi)現實(shi)時(shi)監控(kong)是必(bi)然(ran)的趨勢。為提(ti)高企(qi)業(ye)(ye)的社(she)會效(xiao)益(yi)(yi)和(he)經濟效(xiao)益(yi)(yi)，許多企(qi)業(ye)(ye)都在盡力建立全方位(wei)的管(guan)理信息(xi)系統，它必(bi)須包括生(sheng)產(chan)現場(chang)的實(shi)時(shi)數據信息(xi)，以確保實(shi)時(shi)掌握生(sheng)產(chan)過程的運行狀(zhuang)態，使企(qi)業(ye)(ye)管(guan)理決策(ce)科學化(hua)，達到生(sheng)產(chan)、經營(ying)、管(guan)理的最優化(hua)狀(zhuang)態。信息(xi)壹(yi)控(kong)制壹(yi)體(ti)化(hua)將為實(shi)現企(qi)業(ye)(ye)綜合自動化(hua)CIPA（computerintegratedplantautomation）和(he)企(qi)業(ye)(ye)信息(xi)化(hua)創造有利條件(jian)。
企業信息網絡與控制(zhi)(zhi)(zhi)系統在(zai)體(ti)系結構(gou)發(fa)(fa)展過(guo)(guo)程(cheng)上(shang)(shang)的(de)(de)(de)相似性不是(shi)偶然的(de)(de)(de)。在(zai)計算機(ji)(ji)控制(zhi)(zhi)(zhi)系統的(de)(de)(de)發(fa)(fa)展過(guo)(guo)程(cheng)中，每壹(yi)種結構(gou)的(de)(de)(de)控制(zhi)(zhi)(zhi)系統的(de)(de)(de)出現(xian)總是(shi)滯後(hou)於相應(ying)(ying)計算機(ji)(ji)技(ji)術的(de)(de)(de)發(fa)(fa)展。實際上(shang)(shang)，大多數情(qing)況下，正是(shi)在(zai)計算機(ji)(ji)領域壹(yi)種新(xin)技(ji)術出現(xian)以後(hou)，人(ren)們才開始研究如何將這(zhe)種新(xin)技(ji)術應(ying)(ying)用於控制(zhi)(zhi)(zhi)領域。鑒於兩種應(ying)(ying)用環境的(de)(de)(de)差異(yi)，其中的(de)(de)(de)技(ji)術細節作了適當修改(gai)和補充，但關鍵技(ji)術的(de)(de)(de)原理及(ji)實現(xian)上(shang)(shang)，它們有(you)許多共同的(de)(de)(de)地(di)方。正是(shi)由於二者在(zai)發(fa)(fa)展過(guo)(guo)程(cheng)中的(de)(de)(de)這(zhe)種關系，使得實現(xian)信息壹(yi)控制(zhi)(zhi)(zhi)壹(yi)體(ti)化成為可能。
