【正文】 保護(hù)技術(shù)未來趨勢是向計(jì)算機(jī)化,網(wǎng)絡(luò)化,智能化,保護(hù)、控制、測量和數(shù)據(jù)通信一體化發(fā)展。華中理工大學(xué)、東南大學(xué)、華北電力學(xué)院、西安交通大學(xué)、天津大學(xué)、上海交通大學(xué)、重慶大學(xué)和南京電力自動(dòng)化研究院都相繼研制了不同原理、不同型式的微機(jī)保護(hù)裝置。 自 50 年代末,晶體管繼電保護(hù)已在開始研究。 If thinks after the work method, passes through the massive breakdowns sample training, so long as the sample centralism has fully considered each kind of situation, then in breaks down time any all may correctly distinguish. Other like geic algorithms, the evolution plan and so on also all have its unique solution complex question the ability. May cause the solution speed these artificial intelligence method suitable unions to be quicker. The Tianjin University carries on the nerve work type relay protection from 1996 the research, has yielded the preliminary result ]. May foresee, the artificial intelligence technology must be able to obtain the application in the relay protection domain, by solves the problem which solves with difficulty with the conventional method. 3 Conclution Since the founding of China39。s, started based on the integration operational amplifier integrated circuit protection to study. Has formed the plete series to at the end of 8039。西安科技大學(xué)高新學(xué)院外文翻譯 1 西安科技大學(xué)高新學(xué)院 畢業(yè)設(shè)計(jì) ( 論文 ) 外文翻譯 學(xué)生姓名: 院(系): 專業(yè)班級: 指導(dǎo)教師: 完成日期: 西安科技大學(xué)高新學(xué)院外文翻譯 2 西安科技大學(xué)高新學(xué)院外文翻譯 1 第 1 頁 共 11 頁 Relay protection development present situation [ Abstract ] reviewed our country electrical power system relay protection technological development process, has outlined the microputer relay protection technology achievement, proposed the future relay protection technological development tendency will be: Computerizes, worked, protects, the control, the survey, the data munication integration and the artificial intellectualization. [ Key word ] relay protection present situation development, relay protections future development 1 relay protection development present situation The electrical power system rapid development to the relay protection proposed unceasingly the new request, the electronic technology, puter technology and the munication rapid development unceasingly has poured into the new vigor for the relay protection technology development, therefore, the relay protection technology is advantageous, has completed the development 4 historical stage in more than 40 years time. After the founding of the nation, our country relay protection discipline, the relay protection design, the relay manufacture industry and the relay protection technical team grows out of nothing, has passed through the path in about 10 years which advanced countries half century passes through. The 5039。s integrated circuit protection,substitutes for the transistor protection gradually. The development, the production, the application the integrated circuit protects which to the beginning of the 9039。s electric power system protection technology has undergone four times. With the rapid development of power systems and puter technology, munications technology, relay technology faces the further development of the trend. Domestic and international trends in the development of protection technologies: puterization, working, protection, control, measurement, data munications integration and artificial intelligence, which made protection workers difficult task, but also opened up the activities of vast. 西安科技大學(xué)高新學(xué)院外文翻譯 7 第 7 頁 共 11 頁 繼電保護(hù)發(fā)展現(xiàn)狀 【 摘要 】 回顧我國電力系統(tǒng)繼保護(hù)技術(shù)發(fā)展的過程中,概述了微機(jī)繼電保護(hù)技術(shù)的成就,提出了未來繼電保護(hù)技術(shù) 發(fā)展趨勢將是:計(jì)算機(jī)化,電網(wǎng)絡(luò)化,保護(hù),控制,調(diào)查結(jié)果顯示,數(shù)據(jù)通信一體 化和人工智能化。 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(shí)代。 1984 年原華北電力學(xué)院研制的輸電線路微機(jī)保護(hù)裝置首先通過鑒定,并在系統(tǒng)中獲得應(yīng)用,揭開了我國繼電保護(hù)發(fā)展史上新的一頁,為微機(jī)保護(hù)的推廣開 辟了道路。 計(jì)算機(jī)化 隨著計(jì)算機(jī)硬件的迅猛發(fā)展,微機(jī)保護(hù)硬件也在不斷發(fā)展。 電力系統(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。 (3)采用 std 總線或 pc 總線,硬件模塊化,對于不同的保護(hù)可任意選用不同模塊,配置靈活、容易擴(kuò)展。國外早已提出過系統(tǒng)保護(hù)的概念,這在當(dāng)時(shí)主要指安全自動(dòng)裝置。 對于某些保護(hù)裝置實(shí)現(xiàn)計(jì)算機(jī)聯(lián)網(wǎng),也能提高保護(hù)的可靠性。它可從網(wǎng)上獲取電力系統(tǒng)運(yùn)行和故障的任何信息和數(shù)據(jù),也可將它所獲得的被保護(hù)元件的任何信息和數(shù)據(jù)傳送給網(wǎng)絡(luò)控制中心或任一終端。 ota 和 otv 的光信號輸入到此一體化裝置中并轉(zhuǎn)換成電信號后,一方面用作保護(hù)的計(jì)算判斷;另一方面作為測量量,通過網(wǎng)絡(luò)送到主控室。天津大學(xué)從 1996 年起進(jìn)行神經(jīng)網(wǎng)絡(luò)式繼電保護(hù)的研究,已取得初步成果。 3 結(jié)束語 建國以來,我國電力系統(tǒng)繼電保護(hù)技術(shù)經(jīng)歷了 4 個(gè)時(shí)代。 1992 年天津大學(xué)提出了保護(hù)、控制、測量、通信一體化問題,并研制了以 tms320c25 數(shù)字信號處理器 (dsp)為基礎(chǔ)的一個(gè)保護(hù)、控制、測量、數(shù)據(jù)通信一體化裝置。 目前,為了測量、保護(hù)和控制的需要,室外變電站的所有設(shè)備,如變壓器、線路等的二次電壓、電流都必須用控制電纜引到主控室。其原理是將傳統(tǒng)的集中式母線保護(hù)分散成若干個(gè) (與被保護(hù)母線的回路數(shù)相同 )母線保護(hù)單元,分散裝設(shè)在各回路保護(hù)屏上,各保護(hù)單元用計(jì)算機(jī)網(wǎng)絡(luò)聯(lián)接起來,每個(gè)保護(hù)單元只輸入本 回路的電流量,將其轉(zhuǎn)換成數(shù)字量后,通過計(jì)算機(jī)網(wǎng)絡(luò)傳送給其它所有回路的保護(hù)單元,各保護(hù)單元根據(jù)本回路的電流量和從計(jì)算機(jī)網(wǎng)絡(luò)上獲得的其它所有回路的電流量,進(jìn)行母線差動(dòng)保護(hù)的計(jì)算,如果計(jì)算結(jié)果證明是母線內(nèi)部故障則只跳開本西安科技大學(xué)高新學(xué)院外文翻譯 10 第 10 頁 共 11 頁 回路斷路器,將故障的母線隔離。這就要求每個(gè)保護(hù)單元都能共享全系統(tǒng)的運(yùn)行和故障信息的數(shù)據(jù),各個(gè)保護(hù)單元與重合閘裝置在分析這些信息和數(shù)據(jù)的基礎(chǔ)上協(xié)調(diào)動(dòng)作,確保系統(tǒng)的安全穩(wěn)定運(yùn)行。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(huì)效益,尚須進(jìn)行具體深入的研究。在計(jì)算機(jī)保護(hù)發(fā)展初期,曾設(shè)想過用一臺小型計(jì)算機(jī)作成繼電保護(hù)裝置。華中理工大學(xué)研制的微機(jī)保護(hù)也是從 8 位 cpu,發(fā)展到以工控機(jī)核心部分為基礎(chǔ)的 32 位微機(jī)保護(hù)。南京電力自動(dòng)化研究院研制的微機(jī)線路保護(hù)裝置也于 1991 年通過鑒定。 在此期間,從 70 年代中,基于集成運(yùn)算放大器的集成電路保護(hù)已開始研究。 建國后,我國繼電保護(hù)學(xué)科、繼電保護(hù)設(shè)計(jì)、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(shí)間里走過了先進(jìn)國家半個(gè)世紀(jì)走過的道路。s , the institutions of higher learning and the scientific research courtyard institute forerunner39。s establishment.
