隨著時代的發(fā)展，電網(wǎng)也在向大容量、超高壓方向發(fā)展，面對這樣的形勢所趨，如何實現(xiàn)對于繼電保護故障分析整定管理及仿真系統(tǒng)的開發(fā)和應(yīng)用。筆者結(jié)合實際工作實踐對此進行了相關(guān)的探討。本文首先簡單討論了引進新型繼電保護整定計算軟件的必要性，繼而對繼電保護故障分析整定管理及仿真系統(tǒng)的功能進行了論述，zui后總結(jié)了繼電保護故障分析整定管理及仿真系統(tǒng)在電力工作中的實際應(yīng)用。對于電力系統(tǒng)而言，繼電保護是重要的安全措施之一。因為繼電保護裝置它的選擇性、靈敏性以及可靠性直接會關(guān)系到電網(wǎng)的運行安全。而衡量繼電保護裝置選擇及靈敏性的一個重要指標(biāo)就是繼電保護的定值。因為繼電保護正確合理的定值直接會關(guān)系到電力系統(tǒng)的安全運行，所以對于電力工程而言，繼電保護定值的整定計算具有非常重要的意義。

1 引進新型繼電保護整定計算軟件的必要性

在還沒有新型繼電保護整定計算軟件出現(xiàn)的時候，對于繼電保護的整定計算主要還是依賴于人工手算，有時也會輔助于一些計算設(shè)備，但是因為實際工作當(dāng)中會因為工作量大或者計算費時過長等等原因而造成zui后的結(jié)果與實際結(jié)果的偏差較大。短路計算是繼電保護整定計算工作中的前提和基礎(chǔ)，早期的短路電流計算程序還是在DOS操作系統(tǒng)下完成的。這些軟件在早期雖然被用到電流計算中，但是在實際工作當(dāng)中它還存在著諸多的缺陷，這些缺陷主要突出表現(xiàn)在以下幾個方面，功能、建模方法及管理數(shù)據(jù)庫。

首先系統(tǒng)功能單一。因為該系統(tǒng)只能做好對于部分保護類型的定值計算或者是對故障進行計算，而對于繼電保護專業(yè)管理的工作實際的功能發(fā)揮作用并不大。

其次該建模方法落后。該系統(tǒng)主要利用支路節(jié)點輸入法，在進行支路節(jié)點輸入時它對電網(wǎng)的支路及相關(guān)節(jié)點進行逐一的編號，再以數(shù)據(jù)文件形式輸入，通過這種方式先將電網(wǎng)的原始模型構(gòu)建出來。因為在實際操作過程中這種軟件限制了電網(wǎng)的節(jié)點數(shù)，所以在網(wǎng)架結(jié)構(gòu)復(fù)雜的趨勢下很難跟上地區(qū)電網(wǎng)的發(fā)展速度和步伐。

zui后該系統(tǒng)不具備完善的繼電保護管理數(shù)據(jù)庫。因為缺乏系統(tǒng)和完善的數(shù)據(jù)庫信息所以很難實現(xiàn)電網(wǎng)繼電保護生產(chǎn)管理工作的有效實施。為此，《繼電保護故障分析整定管理及仿真系統(tǒng)》的開發(fā)為解決以上問題提供了新的思路，成為目前許多地區(qū)電網(wǎng)繼電保護生產(chǎn)管理的有效工作平臺。
