電力系統(tǒng)。要想做好繼電保護(hù)技術(shù)的應(yīng)用，首先要對(duì)其發(fā)展過程進(jìn)行了解。本文首先介紹了其發(fā)展的大致歷程，其次介紹了集中目前應(yīng)用的基點(diǎn)保護(hù)技術(shù)，最后提出了電力系統(tǒng)繼電保護(hù)技術(shù)的發(fā)展方向。
一、電力系統(tǒng)繼電保護(hù)技術(shù)的發(fā)展
只有對(duì)電力系統(tǒng)繼電保護(hù)技術(shù)的發(fā)展歷史進(jìn)行了解才能更好地做好現(xiàn)代電力系統(tǒng)繼電保護(hù)技術(shù)的應(yīng)用和改進(jìn)工作。我國(guó)于二十世紀(jì)六七十年代開始應(yīng)用電力系統(tǒng)繼電保護(hù)裝置技術(shù)，起初為晶體管繼電保護(hù)器。隨后的以集成運(yùn)算放大器為基礎(chǔ)的集成電路保護(hù)裝置逐步取代了晶體管繼電保護(hù)器。隨著科學(xué)技術(shù)的發(fā)展，微機(jī)繼電保護(hù)器得到了大力的推廣。從電力系統(tǒng)繼電保護(hù)技術(shù)的發(fā)展歷程可以看到，當(dāng)代電力系統(tǒng)繼電保護(hù)技術(shù)的應(yīng)用與發(fā)展正走向著網(wǎng)絡(luò)化和電子化。
二、電力系統(tǒng)繼電保護(hù)技術(shù)的應(yīng)用
1.要依據(jù)實(shí)際情況選擇設(shè)備類型
電力系統(tǒng)繼電保護(hù)裝置是根據(jù)電力系統(tǒng)的實(shí)際需求來進(jìn)行設(shè)備類型的選擇的，根據(jù)實(shí)際情況對(duì)設(shè)備進(jìn)行選擇是做好繼電保護(hù)技術(shù)的條件基礎(chǔ)。
首先，對(duì)電力系統(tǒng)繼電保護(hù)裝置最基本的要求就是要順利進(jìn)行工作，能夠順利的完成對(duì)系統(tǒng)運(yùn)行狀況的監(jiān)測(cè)、電力系統(tǒng)故障的自動(dòng)切除等工作。其次，由于現(xiàn)代網(wǎng)絡(luò)監(jiān)控技術(shù)的快速發(fā)展，并且在繼電保護(hù)裝置中得到了廣泛的運(yùn)用，這就要求繼電保護(hù)裝置能夠與網(wǎng)絡(luò)監(jiān)控系統(tǒng)協(xié)調(diào)合作，達(dá)到電力系統(tǒng)的自動(dòng)化和網(wǎng)絡(luò)化監(jiān)控所提出的具體要求。因此，在選擇現(xiàn)代電力系統(tǒng)繼電保護(hù)裝置的設(shè)備類型時(shí)，要嚴(yán)格按照電力系統(tǒng)繼電保護(hù)功能順利工作的需要選擇合適的設(shè)備做好繼電保護(hù)工作。此外還要充分考慮設(shè)備和裝置的機(jī)動(dòng)性，安全性，穩(wěn)定性等。
2.電力系統(tǒng)繼電保護(hù)功能應(yīng)用的分析
在電力系統(tǒng)繼電保護(hù)的應(yīng)用中廣泛用到了繼電保護(hù)裝置的電容器保護(hù)、主變保護(hù)、母聯(lián)保護(hù)以及線路保護(hù)等功能。這些功能的應(yīng)用，能夠有效的對(duì)電力系統(tǒng)輸變電過程中的設(shè)備進(jìn)行保護(hù)，從而避免了故障的發(fā)生，節(jié)省了資金。
