【摘要】：電力工業(yè)業(yè)是關(guān)系國(guó)計(jì)民生的重要行業(yè)。面對(duì)電網(wǎng)中復(fù)雜的生產(chǎn)管理狀況,電網(wǎng)工作人員需要及時(shí)全面的了解電網(wǎng)運(yùn)行中的各種信息,其中,有功、無(wú)功、負(fù)荷等實(shí)時(shí)數(shù)據(jù)是最為關(guān)鍵的部分,它能反映出電網(wǎng)的實(shí)時(shí)運(yùn)行狀態(tài)與健康狀況。但實(shí)時(shí)數(shù)據(jù)具有數(shù)據(jù)量大、變化速度快、不易觀測(cè)等特點(diǎn)。以可縮放矢量圖形(Scalable Vector Graphics, SVG)作為電力系統(tǒng)一次接線圖和地理接線圖的圖形格式進(jìn)行實(shí)時(shí)數(shù)據(jù)的動(dòng)態(tài)顯示是一種有效方式。但是目前的方案中明顯存在著一些不足,比如關(guān)鍵信息不突出,數(shù)據(jù)是“被動(dòng)”實(shí)時(shí),網(wǎng)絡(luò)傳輸消耗大等,并不能滿足實(shí)際的需求。 本文從電力行業(yè)中實(shí)時(shí)數(shù)據(jù)的應(yīng)用出發(fā),依托于輸變電設(shè)備狀態(tài)可視化智能管理平臺(tái)的建設(shè)需求,研究相關(guān)的實(shí)時(shí)數(shù)據(jù)動(dòng)態(tài)顯示技術(shù)。實(shí)現(xiàn)了基于SVG的電網(wǎng)實(shí)時(shí)數(shù)據(jù)動(dòng)態(tài)顯示系統(tǒng)。通過(guò)電力SVG技術(shù)展示電力一次接線圖,并以此作為載體,動(dòng)態(tài)的呈現(xiàn)實(shí)時(shí)數(shù)據(jù)以及相應(yīng)歷史數(shù)據(jù)。使用劃分專題圖層和配置報(bào)警策略的方式,明確突出各監(jiān)測(cè)主題中的關(guān)鍵信息與不安全狀態(tài)。同時(shí)采用服務(wù)器推送技術(shù),變服務(wù)器的“被動(dòng)”響應(yīng)為“主動(dòng)”推送,提高了數(shù)據(jù)的實(shí)時(shí)性,并減少了數(shù)據(jù)傳輸量。采用J2EE的系統(tǒng)架構(gòu),提供了良好地穩(wěn)定性、可移植性、靈活性、易維護(hù)性機(jī)制。論文成果已在輸變電設(shè)備狀態(tài)可視化智能管理平臺(tái)投入使用,并取一定效果。應(yīng)用表明,通過(guò)實(shí)時(shí)數(shù)據(jù)的動(dòng)態(tài)顯示,工作人員可以及時(shí)的把握所關(guān)心的數(shù)據(jù),進(jìn)行針對(duì)性監(jiān)測(cè),提高了工作效率,這也驗(yàn)證了論文成果的正確性與有效性。
[Abstract]:Electric power industry is an important industry related to the national economy and people's livelihood.In the face of the complex production management situation in the power network, grid workers need to understand all kinds of information in time and comprehensively in the operation of the power grid. Among them, real-time data such as active power, reactive power, load and so on are the most critical parts.It can reflect the real-time operation state and health condition of the power grid.It is an effective way to dynamically display real-time data with scalable Vector graphics (SVG) as the graphic format of primary wiring diagram and geographical wiring diagram of power system.But there are some shortcomings in the current scheme, such as the key information is not prominent, the data is "passive" real-time, the network transmission consumption is large, and can not meet the actual needs.Starting from the application of real-time data in power industry, this paper studies the related real-time data dynamic display technology based on the construction demand of the state visualization intelligent management platform of power transmission and transformation equipment.The real-time data dynamic display system based on SVG is realized.The power primary wiring diagram is displayed by power SVG technology, which is used as a carrier to dynamically present real-time data and corresponding historical data.By dividing the thematic layer and configuring the alarm strategy, the key information and unsafe state in each monitoring topic are clearly highlighted.At the same time, the server push technology is used to change the "passive" response of the server to "active" push, which improves the real-time performance of the data and reduces the amount of data transmission.The system structure of J2EE provides good stability, portability, flexibility and maintainability mechanism.The results of this paper have been put into use in the intelligent management platform of transmission and transformation equipment, and some effects have been obtained.The application shows that through the dynamic display of real-time data, the staff can grasp the concerned data in time, monitor the work effectively and improve the work efficiency, which also verifies the correctness and effectiveness of the paper.
