【摘要】：隨著我國工業(yè)的發(fā)展與進步,工業(yè)設(shè)備呈現(xiàn)出大型化與智能化的發(fā)展趨勢,在大型工業(yè)中,以維修性和可靠性為指標的安全儀表系統(tǒng)對大型工業(yè)設(shè)備正常運行有重要輔助作用。電力工業(yè)近些年也呈現(xiàn)出大型化與智能化的特點,高效安全的進行電力生產(chǎn)是安全儀表系統(tǒng)研究人員關(guān)注的問題。目前國內(nèi)電力系統(tǒng)的維修策略大多是以定期維修為主,依據(jù)維修人員工程經(jīng)驗選定維修時間,此方法缺乏理論支撐,沒有現(xiàn)場數(shù)據(jù)驗證�；跔顟B(tài)的維修策略在軍工,航天,石化領(lǐng)域應用比較廣泛,但其在電力系統(tǒng)的應用不常見。本文首先對國內(nèi)外的安全儀表維修策略的現(xiàn)狀進行了分析與研究,針對安全儀表系統(tǒng)以及安全標準進行了一定的介紹,對比了三種安全儀表的維修策略,比如定期維修,基于狀態(tài)維修以及可靠性的維修等,除此之外,選擇火電廠主燃料跳閘中全爐膛滅火保護子功能和變電站儀器儀表系統(tǒng)中過電壓、過電流跳閘子系統(tǒng)作為研究對象。為對上述系統(tǒng)進行研究,首先根據(jù)火電廠日常生產(chǎn)運行數(shù)據(jù),利用安全性與可靠性理論,以IEC61508及IEC61511為原則,得出故障樹模型并對系統(tǒng)進行安全評估進而得出安全完整性等級;其次,依據(jù)變電站儀器儀表系統(tǒng)實際特點,提出變電站定期維修策略,綜合考慮可用性、可靠性、維修成本,應用多目標優(yōu)化策略,使用遺傳算法,得出了最優(yōu)的維修間隔,為變電站檢修工作提供參考意見。最后,經(jīng)過對變電站和火電廠的安全評估以及維修策略研究,得出影響火電廠和變電站安全性的主要因素并指出改進方向。
[Abstract]:With the development and progress of China's industry, industrial equipment presents a trend of large-scale and intelligent development. In large-scale industry, the safety instrument system, which takes maintainability and reliability as the index, plays an important role in the normal operation of large-scale industrial equipment. In recent years, the power industry also presents the characteristics of large-scale and intelligent, efficient and safe power production is a safety instrument system researchers pay attention to. At present, the maintenance strategy of domestic electric power system is mostly based on periodic maintenance, and the maintenance time is selected according to the engineering experience of maintainers. This method lacks theoretical support and field data verification. State based maintenance strategy is widely used in military, aerospace and petrochemical fields, but its application in power system is unusual. Firstly, this paper analyzes and studies the present situation of the maintenance strategy of safety instruments at home and abroad, introduces the safety instrument system and safety standards, and compares the maintenance strategies of three kinds of safety instruments, such as periodic maintenance. Based on the condition maintenance and reliability maintenance, in addition, the whole furnace fire extinguishing protection sub-function in the main fuel tripping of thermal power plant and the over-voltage and over-current tripping subsystem in the instrument and instrument system of the substation are selected as the research objects. In order to study the system mentioned above, firstly, according to the daily operation data of thermal power plant, using the theory of safety and reliability, taking IEC61508 and IEC61511 as the principles, the fault tree model is obtained and the safety evaluation of the system is carried out, and the safety integrity grade is obtained. Secondly, according to the actual characteristics of substation instrumentation system, the paper puts forward the substation regular maintenance strategy, considers availability, reliability, maintenance cost, applies multi-objective optimization strategy, and uses genetic algorithm to obtain the optimal maintenance interval. To provide reference for substation maintenance work. Finally, by studying the safety evaluation and maintenance strategy of substation and thermal power plant, the main factors affecting the safety of thermal power plant and substation are obtained and the direction of improvement is pointed out.
