used in puter, such as microelectronics devices, immediately RTU power dispatch system of rapid development, the user has throughout the country, function also is more and more abundant, can bring many for people39。s life convenient, therefore introduce electric power dispatching automation of the typical application of electric power dispatching automation system lightning protection new technology: power system equipotential technology and lightning arrester residual pressure attenuation technology. Hope everybody can to power dispatch of a good understanding.Key words:electric power systems, Dispatching automation。 Lightningproof technique引言隨著電力系統(tǒng)容量的增加和自動化水平的不斷提高,電力調(diào)度自動化系統(tǒng)已廣泛使用計算機、RTU等微電子設(shè)備。縣級電力調(diào)度及其變電站由于其所在地土壤電阻率較高或地處山區(qū)等,其地網(wǎng)的接地電阻往往很難達到規(guī)程的要求,其防雷工作更需引起重視。由于一些微電子器件工作電壓僅幾伏,傳遞信息電流小至微安級,對外界的干擾極其敏感,而雷電流產(chǎn)生的瞬變電磁場對微電子設(shè)備的干擾和損害尤為嚴(yán)重。在雷雨季節(jié),有些縣電力公司調(diào)度大樓和電力公司所屬自動化顯示系統(tǒng)、通信聯(lián)絡(luò)系統(tǒng)(Modem、載波機、程控交換機等)等常常遭到雷擊,造成較大的經(jīng)濟損失,嚴(yán)重影響當(dāng)?shù)仉娏ο到y(tǒng)的正常調(diào)度、工農(nóng)業(yè)生產(chǎn)和人民的日常生活。盡管有些電力調(diào)度自動化系統(tǒng)采取了一定的
