硬件質(zhì)量問題

某300MW機(jī)組，正常運(yùn)行中發(fā)電機(jī)出口開關(guān)、勵磁開關(guān)跳閘，“調(diào)節(jié)器A柜退出運(yùn)行”、“調(diào)節(jié)器B柜退出運(yùn)行”報(bào)警信號發(fā)出，機(jī)組解列。對ECS檢查試驗(yàn)，發(fā)現(xiàn)控制A、B柜調(diào)節(jié)器的主控制器離線，與之冗余的控制器重啟。分析發(fā)現(xiàn)控制器主板晶振存在問題，聯(lián)系制造廠予以全部免費(fèi)更換。

要重視DCS的FAT工廠測試，派有經(jīng)驗(yàn)的技術(shù)人員參與DCS出廠的性能測試和驗(yàn)收，爭取及早發(fā)現(xiàn)并解決問題，盡量避免在運(yùn)行中發(fā)生問題。

再如某300MW機(jī)組，運(yùn)行中所有磨煤機(jī)跳閘，MFT動作，機(jī)組跳閘。分析發(fā)現(xiàn)故障原因是DCS選用集線器上的總通訊板故障，導(dǎo)致與其通信的所有控制器同時切換至備用。切換過程中，F(xiàn)SSS功能三個控制器誤發(fā)磨煤機(jī)跳閘信號，后用CISCO集線器更換。

對于DCS供應(yīng)商在配套設(shè)備上的選型應(yīng)提出要求或者規(guī)定產(chǎn)品型號，避免采用即將淘汰或非主流產(chǎn)品。
