31、建國后，我國繼電保護(hù)學(xué)科、繼電保護(hù)設(shè)計、繼電器制造工業(yè)和繼電保護(hù)技術(shù)隊(duì)伍從無到有，在大約10年的時間里走過了先進(jìn)國家半個世紀(jì)走過的道路。50年代，我國工程技術(shù)人員創(chuàng)造性地吸收、消化、掌握了國外先進(jìn)的繼電保護(hù)設(shè)備性能和運(yùn)行技術(shù)，建成了一支具有深厚繼電保護(hù)理論造詣和豐富運(yùn)行經(jīng)驗(yàn)的繼電保護(hù)技術(shù)隊(duì)伍，對全國繼電保護(hù)技術(shù)隊(duì)伍的建立和成長起了指導(dǎo)作用。阿城繼電器廠引進(jìn)消化了當(dāng)時國外先進(jìn)的繼電器制造技術(shù)，建立了我國自己的繼電器制造業(yè)。因而在60年代中

32、我國已建成了繼電保護(hù)研究、設(shè)計、制造、運(yùn)行和教學(xué)的完整體系。這是機(jī)電式繼電保護(hù)繁榮的時代，為我國繼電保護(hù)技術(shù)的發(fā)展奠定了堅實(shí)基礎(chǔ)?！　?自50年代末，晶體管繼電保護(hù)已在開始研究。60年代中到80年代中是晶體管繼電保護(hù)蓬勃發(fā)展和廣泛采用的時代。其中天津大學(xué)與南京電力自動化設(shè)備廠合作研究的500kV晶體管方向高頻保護(hù)和南京電力自動化研究院研制的晶體管高</p><p>　　繼電保護(hù)技術(shù)未來趨勢是向計算機(jī)化，網(wǎng)絡(luò)化，

33、智能化，保護(hù)、控制、測量和數(shù)據(jù)通信一體化發(fā)展?！　‰娏ο到y(tǒng)對微機(jī)保護(hù)的要求不斷提高，除了保護(hù)的基本功能外，還應(yīng)具有大容量故障信息和數(shù)據(jù)的長期存放空間，快速的數(shù)據(jù)處理功能，強(qiáng)大的通信能力，與其它保護(hù)、控制裝置和調(diào)度聯(lián)網(wǎng)以共享全系統(tǒng)數(shù)據(jù)、信息和網(wǎng)絡(luò)資源的能力，高級語言編程等。這就要求微機(jī)保護(hù)裝置具有相當(dāng)于一臺PC機(jī)的功能。在計算機(jī)保護(hù)發(fā)展初期，曾設(shè)想過用一臺小型計算機(jī)作成繼電保護(hù)裝置。由于當(dāng)時小型機(jī)體積大、成本高、可靠性差，這個設(shè)想是不現(xiàn)

34、實(shí)的。現(xiàn)在，同微機(jī)保護(hù)裝置大小相似的工控機(jī)的功能、速度、存儲容量大大超過了當(dāng)年的小型機(jī)，因此，用成套工控機(jī)作成繼電保護(hù)的時機(jī)已經(jīng)成熟，這將是微機(jī)保護(hù)的發(fā)展方向之一?！　?繼電保護(hù)裝置的微機(jī)化、計算機(jī)化是不可逆轉(zhuǎn)的發(fā)展趨勢。但對如何更好地滿足電力系統(tǒng)要求，如何進(jìn)一步提高繼電保護(hù)的可靠性，如何取得更大的經(jīng)濟(jì)效益和社會效益，尚須進(jìn)行具體深入的研究。　　 計算機(jī)網(wǎng)絡(luò)作為信息和數(shù)據(jù)通信工具已成為信息時代的技術(shù)支柱，使人類生產(chǎn)和社會生活的面

35、貌發(fā)生了根本變化。它深刻影響著各個工業(yè)領(lǐng)域，也為各個工業(yè)領(lǐng)域提供了強(qiáng)有力的通信</p><p>　　近年來，人工智能技術(shù)如神經(jīng)網(wǎng)絡(luò)、遺傳算法、進(jìn)化規(guī)劃、模糊邏輯等在電力系統(tǒng)各個領(lǐng)域都得到了應(yīng)用，在繼電保護(hù)領(lǐng)域應(yīng)用的研究也已開始。神經(jīng)網(wǎng)絡(luò)是一種非線性映射的方法，很多難以列出方程式或難以求解的復(fù)雜的非線性問題，應(yīng)用神經(jīng)網(wǎng)絡(luò)方法則可迎刃而解。例如在輸電線兩側(cè)系統(tǒng)電勢角度擺開情況下發(fā)生經(jīng)過渡電阻的短路就是一非線性問題，距
