硬件質量問題

某300MW機組，正常運行中發(fā)電機出口開關、勵磁開關跳閘，“調節(jié)器A柜退出運行”、“調節(jié)器B柜退出運行”報警信號發(fā)出，機組解列。對ECS檢查試驗，發(fā)現控制A、B柜調節(jié)器的主控制器離線，與之冗余的控制器重啟。分析發(fā)現控制器主板晶振存在問題，聯系制造廠予以全部免費更換。

要重視DCS的FAT工廠測試，派有經驗的技術人員參與DCS出廠的性能測試和驗收，爭取及早發(fā)現并解決問題，盡量避免在運行中發(fā)生問題。

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

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