對于設計人員缺乏創新的機制和動力。在工程中應用新技術總會有一定的風險,這
需要設計人員投入大量的精力進行調研和方案論證,但現實往往是對應用新技術的
研究沒有額外的投入,尤其對新技術的成功應用也并無特別的獎勵機制。
另外,還應考慮到現場總線的可靠性和可用性。
因為電廠發電機組連續安全穩定運行是至關重要的。
控制系統的可靠性是保證機組可用
率的重要因素。為了提高系統的可靠性,現場總線技術
(FF
和
Profibus)
已經采用了多項措
施,常用的有分散和冗余二項。
①
分散方面。對
FCS
系統而言,主要通過網絡分散和控制分散來提高可用性。除去將
一般控制功能下放到現場,
設計中通過上層網絡的區域劃分和下層網絡的風險管理等,
做到
一個回路的故障不影響到另一個回路。在工程設計中,建議主要控制策略還是采用常規
DCS
應用方式,
按工藝系統分散在不同的控制器內實現,
功能分散能夠滿足要求。
火電廠機組控
制中存在大量控制回路之間的相互聯鎖、
信號交換,
當不同檢測控制設備處在不同網絡分段
時,如何確保它們之間聯鎖、交換信號的實時可靠性將是一個需要關注的問題。
