【摘要】：近年來隨著國民經(jīng)濟(jì)的快速增長,電力的需求量不斷增加,火電廠控制系統(tǒng)實(shí)現(xiàn)全面數(shù)字化的要求也日益增高,目前電廠的現(xiàn)場控制設(shè)備絕大部分尚未實(shí)現(xiàn)數(shù)字化,傳統(tǒng)的DCS(Distributed Control System)由于其單向性特點(diǎn),不能滿足數(shù)字化電廠的要求,而現(xiàn)場總線技術(shù)的推廣應(yīng)用能夠很好地解決這一問題。本文首先論述了現(xiàn)場總線技術(shù)的特點(diǎn)、系統(tǒng)結(jié)構(gòu)和國內(nèi)外的應(yīng)用情況及發(fā)展現(xiàn)狀,通過對比分析幾種常見的現(xiàn)場總線標(biāo)準(zhǔn)的技術(shù)特點(diǎn)、通信方式及應(yīng)用場合等;其次,分析電廠傳統(tǒng)的控制系統(tǒng)的作用、數(shù)字化電廠控制系統(tǒng)的要求,并對其在現(xiàn)場設(shè)備層采用現(xiàn)場總線系統(tǒng)的配置方案、設(shè)計(jì)原則、注意事項(xiàng)等逐一進(jìn)行了分析;再次,以江蘇沙洲電廠二期2×1000MW機(jī)組擴(kuò)建工程為例,選擇PROFIBUS-DP和FF總線(Foundation Fieldbus)以及HART總線(Highway Addressable Remote Transducer),設(shè)計(jì)其單元機(jī)組和輔助生產(chǎn)控制系統(tǒng)的兩個方面的現(xiàn)場總線方案,并在工程造價方面,與DCS進(jìn)行了投資對比分析,結(jié)果表明,采用現(xiàn)場總線技術(shù)后,不僅在設(shè)備的初次投資方面節(jié)省了資金,而且在設(shè)備安裝、調(diào)試、運(yùn)行維護(hù)方面也節(jié)約了時間和資金,同時,現(xiàn)場總線技術(shù)的應(yīng)用還有利于電廠的全面實(shí)現(xiàn)設(shè)備監(jiān)控和管理的數(shù)字化;之后,應(yīng)用現(xiàn)場總線控制系統(tǒng)診斷軟件從報警事件、在線診斷和歷史記錄三個方面進(jìn)行設(shè)備管理與診斷,并同常規(guī)的DCS控制系統(tǒng)進(jìn)行對比。最后,圍繞電廠信息系統(tǒng)展開,實(shí)現(xiàn)電廠全過程的信息數(shù)字化、網(wǎng)絡(luò)化、集成化,為企業(yè)及時提供準(zhǔn)確有效的信息服務(wù)。
[Abstract]:In recent years, with the rapid growth of national economy, the demand for electric power is increasing, and the requirement of full digitization of thermal power plant control system is increasing day by day. At present, most of the field control equipment in power plant has not been digitized.Traditional DCS(Distributed Control system can not meet the requirement of digital power plant because of its unidirectional characteristics, but the popularization and application of fieldbus technology can solve this problem well.This paper first discusses the characteristics of fieldbus technology, system structure, application situation and development status at home and abroad, through comparative analysis of several common fieldbus standards technical characteristics, communication methods and applications, etc.This paper analyzes the function of traditional control system in power plant, the requirements of digital power plant control system, and analyzes the configuration scheme, design principle and matters needing attention of the field bus system in the field equipment layer one by one.Taking the 2 脳 1000MW unit expansion project of Jiangsu Shazhou Power Plant as an example, the field bus schemes of PROFIBUS-DP and FF bus Foundation Fieldbus and HART bus Highway Addressable Remote Transducer are selected to design the two aspects of unit unit and auxiliary production control system, and the project cost.Compared with DCS, the results show that the field bus technology not only saves money in the initial investment of equipment, but also saves time and money in installation, debugging, operation and maintenance of equipment.The application of fieldbus technology is also conducive to the overall realization of the digitization of equipment monitoring and management in power plants. After that, the diagnosis software of fieldbus control system is used from alarm events.Equipment management and diagnosis are carried out in three aspects: online diagnosis and history record, and compared with conventional DCS control system.Finally, focusing on the power plant information system to realize the whole process of power plant information digitization, networking, integration, for enterprises to provide timely accurate and effective information services.
