The operation reliability of the power transformer as the key equipment in electrical power systems, influences operation security of electrical power systems directly. the components and contents of gases dissolved in transformer oil can be used to reflects internal insulation faults of operating transformer. in order to overcome the errors caused by complex handling procedure and man - made factors using general chromatogram analysis method, author brings forward an on - line detecting of gases dissolved in transformer oil by using macromolecule polymer to separate oil and gases automatically and an information fusion technology of multi - sensors ; at the same time, in order to improve the accuracy and reliability, author uses neural networks to diagnose transformer faults
變壓器作為電力系統的樞紐設備，其運行可靠性直接影響電力系統的安全運行；變壓器油中溶解氣體的成分和含量能有效體現運行變壓器內部的絕緣故障情況，為解決常規色譜分析中復雜的操作程序和由於人為因素引起的較大的誤差，論文提出了應用高分子聚合膜實現變壓器油氣自動分離、多傳感信息融合技術智能檢測多種氣體成分的變壓器油中溶解氣體在線監測技術，應用神經網路智能診斷方法實施故障診斷，提高變壓器故障診斷的準確性和可靠性。Fluidization has been assumed as an efficient means of contacting different particles in various fields such as chemical, metallurgical and pharmaceutical industries. however, the hydro - dynamical behavior of gas - solid bed is very complex. in this paper, based on a large amount of experimental data, complexity theory are adopted as a new method to study on the multi - signals especially pressure signal in wide flow region in gas solid fluidized bed which respective diameter are 114mm and 250mm
本文在氣固流化床中引入復雜性理論作為主要的研究工具，在114mm和250mm床徑氣固流化床中進行了大量的實驗，選用分別屬于a類和b類的粒子作為固體顆粒，在寬流域的范圍內對流化床壓力信號、顆粒濃度信號，尤其是壓力信號進行了研究。The pressure difference signal was acquired under different air and pulverized coal flow condition on gas - solid test - bed. on the basis of studying chaos theory and its application, a set of software used to analyze characteristic numbers of chaotic time series is accomplished, deterministic chaos theory is applied to the pressure difference series by the software, and some preliminary conclusions are drawn. li yu ( thermal power engineering ) directed by prof. chen hongwei, prof. guan jinfeng
在氣固兩相流實驗臺上進行不同工況下的空氣和煤粉兩相流動試驗，採集得到差壓信號時間序列；在總結混沌理論及應用基礎上，編制一套較為完整的混沌時間序列特徵量分析軟體；使用該軟體，將確定性混沌理論應用在兩相流不同工況的差壓時間序列分析中，認為相空間吸引子圖和延遲時間可以用來對兩相流流動狀況進行定性的判斷。
