對于設(shè)計人員缺乏創(chuàng)新的機制和動力。在工程中應(yīng)用新技術(shù)總會有一定的風(fēng)險，這
需要設(shè)計人員投入大量的精力進行調(diào)研和方案論證，但現(xiàn)實往往是對應(yīng)用新技術(shù)的
研究沒有額外的投入，尤其對新技術(shù)的成功應(yīng)用也并無特別的獎勵機制。
 
另外，還應(yīng)考慮到現(xiàn)場總線的可靠性和可用性。
 
因為電廠發(fā)電機組連續(xù)安全穩(wěn)定運行是至關(guān)重要的。
控制系統(tǒng)的可靠性是保證機組可用
率的重要因素。為了提高系統(tǒng)的可靠性，現(xiàn)場總線技術(shù)

已經(jīng)采用了多項措

分散方面。對
FCS
系統(tǒng)而言，主要通過網(wǎng)絡(luò)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(xiàn)場，
設(shè)計中通過上層網(wǎng)絡(luò)的區(qū)域劃分和下層網(wǎng)絡(luò)的風(fēng)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(shè)計中，建議主要控制策略還是采用常規(guī)

按工藝系統(tǒng)分散在不同的控制器內(nèi)實現(xiàn)，
功能分散能夠滿足要求。
火電廠機組控

信號交換，
當(dāng)不同檢測控制設(shè)備處在不同網(wǎng)絡(luò)分段
時，如何確保它們之間聯(lián)鎖、交換信號的實時可靠性將是一個需要關(guān)注的問題。
