【摘要】：隨著電力系統(tǒng)規(guī)模的擴(kuò)大和互聯(lián)程度的提高,當(dāng)電力系統(tǒng)發(fā)生故障時(shí),故障的傳播范圍將更大,其造成的危害也更大。尤其發(fā)生復(fù)雜故障時(shí),電力系統(tǒng)的信息系統(tǒng)將接收到大量的故障數(shù)據(jù),給故障診斷造成了極大的困難。故加強(qiáng)電力系統(tǒng)故障診斷的研究,以指導(dǎo)調(diào)度人員應(yīng)對故障,對電力系統(tǒng)的安全穩(wěn)定具有較強(qiáng)的現(xiàn)實(shí)意義。本文引入復(fù)雜事件處理技術(shù)來解決現(xiàn)有電力系統(tǒng)故障信息處理中存在的數(shù)據(jù)過剩而信息不足的問題。從電力系統(tǒng)間隔層故障數(shù)據(jù)、變電主站故障信息和調(diào)度中心診斷結(jié)論的本質(zhì)區(qū)分出發(fā),根據(jù)現(xiàn)有電力系統(tǒng)故障信息的處理層次特點(diǎn),提出了基于復(fù)雜事件處理技術(shù)的電力系統(tǒng)故障診斷信息處理的分層處理模型。在此基礎(chǔ)上,采用復(fù)雜事件處理技術(shù)中主流的事件處理語言PAPIDE-EPL建立了電力系統(tǒng)故障診斷的事件抽象層次及各層事件之間的聚合規(guī)則�；趶�(fù)雜事件處理技術(shù)的電力系統(tǒng)故障診斷方法符合故障信息處理的本質(zhì),其從數(shù)據(jù)層、信息層和知識層3個(gè)層面逐步處理故障數(shù)據(jù),降低了故障事件模式匹配規(guī)則的難度,加強(qiáng)了匹配規(guī)則的適應(yīng)性,改善了故障診斷過程的黑箱性。針對局部電力系統(tǒng)的算例,文本采用復(fù)雜事件處理平臺StreamInsight建立了電力系統(tǒng)故障診斷系統(tǒng)。算例測試結(jié)果表明本文提出的基于復(fù)雜事件處理技術(shù)的電力系統(tǒng)故障診斷模型合理,故障診斷診斷方法有效,具有較好的應(yīng)用前景。
[Abstract]:With the expansion of power system scale and the improvement of interconnection degree, when the power system fails, the range of fault propagation will be larger, and the harm caused by it will also be greater.Especially when complex faults occur, the power system information system will receive a large number of fault data, causing great difficulties in fault diagnosis.Therefore, it is of great practical significance to strengthen the research of power system fault diagnosis to guide the dispatcher to deal with the fault and to ensure the safety and stability of the power system.In this paper, complex event processing technology is introduced to solve the problem of data surplus and insufficient information in existing power system fault information processing.Based on the essential distinction between the fault data of power system interval layer, the fault information of substation main station and the diagnosis conclusion of dispatching center, according to the characteristics of the existing power system fault information processing hierarchy,A hierarchical processing model for fault diagnosis information processing in power system based on complex event processing technology is proposed.On the basis of this, the abstract event hierarchy of power system fault diagnosis and the aggregation rules among the events in the power system fault diagnosis are established by using the event processing language PAPIDE-EPL, which is the mainstream of complex event processing technology.The fault diagnosis method of power system based on complex event processing technology accords with the essence of fault information processing. It processes fault data step by step from three levels: data layer, information layer and knowledge layer, which reduces the difficulty of fault event pattern matching rule.The adaptability of matching rules is enhanced and the black box of fault diagnosis process is improved.In this paper, the fault diagnosis system of local power system is established by using complex event processing platform StreamInsight.The test results show that the proposed fault diagnosis model based on complex event processing technology is reasonable, and the fault diagnosis method is effective and has a good application prospect.
