描述
SOE的結(jié)論對(duì)事故的分析判斷起了很重要的作用,但在現(xiàn)實(shí)中,許多電廠發(fā)生保護(hù)動(dòng)作等情況時(shí)SOE未記錄下來(lái)或記錄時(shí)間與實(shí)際情況不符。如電廠#1機(jī)組出現(xiàn)過(guò)SOE事件順序追憶時(shí)間與實(shí)際跳閘時(shí)間不相對(duì)應(yīng),SOE時(shí)間打印瀏覽后不能返回,首次跳閘原因在事件順序吵能第一個(gè)反映,SOE時(shí)間順序數(shù)據(jù)不能設(shè)置等問(wèn)題。而有的電廠在幾次事故分析時(shí)發(fā)現(xiàn)SOE結(jié)論中的時(shí)序與歷史曲線中的時(shí)序有偏差,有時(shí)甚至?xí)r序顛倒,具體表現(xiàn)于同一點(diǎn)在歷史曲線和SOE中民生時(shí)間不一致,且有時(shí)偏差很大,這會(huì)延誤事故分析的進(jìn)程,有時(shí)甚至誤導(dǎo)事故分析方向。SOE問(wèn)題既與系統(tǒng)設(shè)計(jì)不合理,SOE點(diǎn)沒(méi)完全集中在一個(gè)上有關(guān),也與系統(tǒng)硬件及軟件設(shè)計(jì)考慮不周有關(guān)。
