配電網(wǎng)自動化建設(shè)，在我國盡管起步較晚，但也已經(jīng)進行了近20年的研究和實踐，取得初步成效。但是研究與實踐成果大多數(shù)都是在高壓配電網(wǎng)（35 k V以上）層次上進行的，而在中低壓配電網(wǎng)（配電房這一層次）的自動化問題上，還是一片空白，既沒有總體的規(guī)劃，也沒有一個統(tǒng)一的技術(shù)原則。不僅如此，目前的縱向監(jiān)控一般只限于變電站的出線以前，對于從變電站饋線到終端用戶等屬于用電管理范疇的監(jiān)控，除少數(shù)大用戶的負荷控制外，尚無其它監(jiān)控手段。
2 中低壓配電網(wǎng)自動化方案
2．1 電力系統(tǒng)自動化現(xiàn)有方案的比較
中低壓配電網(wǎng)（主要指開關(guān)站、開關(guān)房、開閉所）的自動化和變電站的自動化具有一定的相似性。因此，分析一下變電站自動化的實現(xiàn)方法，對于正確確定中低壓配電網(wǎng)自動化方案具有重要意義。
變電站自動化系統(tǒng)由5個部分組成：主站、遠方終端單元（re mote terminal units，RTU）、線路傳感器、遠方控制SF6或真空開關(guān)、通信電纜。其中，RTU裝置位于變電站現(xiàn)場，可以自動采集各種開關(guān)狀態(tài)量（遙信）、模擬量（遙測），并經(jīng)專用通道傳遞到監(jiān)控中心的主站系統(tǒng)；有的RTU還可以按監(jiān)控人員的意圖和指令執(zhí)行特定的遙控操作，并將操作結(jié)果返送監(jiān)控中心主站系統(tǒng)。
從變電站RTU可以實現(xiàn)的功能來看，變電站的自動化包括3個方面的內(nèi)容：遙信、遙測、遙控。除此之外，有的系統(tǒng)還可以根據(jù)遙測的結(jié)果實現(xiàn)電能量總加功能。與此相應(yīng)，變電站自動化系統(tǒng)可以分為兩類：一類只實現(xiàn)了遙信、遙測的功能，即傳統(tǒng)的SCADA系統(tǒng)；而最新的SCADA 系統(tǒng)則屬于另外一類，它應(yīng)該可以實現(xiàn)所有“三遙”功能。這兩類系統(tǒng)對應(yīng)著電力系統(tǒng)自動化的不同階段和水平。
