摘要:伴隨著這些年來隨著我國繼電保護技術(shù)和計算機技術(shù)的快速發(fā)展，微機型繼電保護系統(tǒng)在變電站電力系統(tǒng)中已經(jīng)得到了極為廣泛的應(yīng)用。微機保護系統(tǒng)已成為當(dāng)前變電站二次設(shè)備的主要組成部分。由于目前變電站本身已經(jīng)成為一個巨大的電磁網(wǎng)，這種強電磁網(wǎng)必然會對電力設(shè)備產(chǎn)生各種電磁干擾，特別是對變電站微機保護裝置的影響尤為嚴(yán)重。所以對變電站以微機保護裝置為主的二次回路進行綜合分析和研究，并且采取一些必要的抗干擾措施，同時對變電站微機保護裝置進行有針對性的防護就顯得非常重要了。 本文以35kV變電站為例，首先詳細分析了35kV變電站電力系統(tǒng)二次回路的干擾源和其傳播途徑，并對占35kV變電站二次回路主要部分的變電站微機保護系統(tǒng)做了簡要介紹，然后對目前35kV變電站電力系統(tǒng)中各微機保護裝置的常用抗干擾措施進行了研究和探討，提出了對整個35kV變電站二次回路以及微機保護裝置所要采取的必要抗干擾措施，最后介紹了在35kV變電站實際運行中出現(xiàn)的幾種典型干擾及其應(yīng)對措施和在變電站實際建設(shè)工程中所采取的抗干擾措施。 關(guān)鍵詞：變電站；微機保護；抗干擾；措施
ABSTRACT:In recent years, with the technology and computer technology, the rapid development of China's power industry technology relay, substation power systems, microprocessor-based relay protection system has been applied very widely. Protection system has become the main city part of the substation secondary equipment. The electromagnetic network is inevitable due to the substation itself is a huge network of electromagnetic power equipment electromagnetic interference, especially for weak computer protection device. And electrical equipment within the substation power system operation, electrical equipment around the electrostatic field and the magnetic field, corona and electromagnetic radiation caused by electromagnetic interference, can easily result in incorrect operation of computer protection device. Therefore a comprehensive analysis of the substation secondary circuit configuration of the microcomputer protection and research, to take the necessary anti-jamming measures targeted protection is particularly important. This article first detailed analysis of the sources of interference in the secondary circuit 35kV substation power system and the route of transmission, and accounted for the 35kV substation secondary circuit of the main part of the substation computer protection system gives a brief introduction, and then the computer substation power system protection devices commonly used anti-jamming measures studied and discussed the necessary anti-jamming measures to be taken on the entire 35kV substation secondary circuit as well as the computer protection device, and finally appear in the actual operation of 35kV substation several typical interference and response measures and anti-jamming measures taken in substation construction project. Keywords: substation; microcomputer protection; interference; measures.
