  1. This thesis studies the law of affecting de - noise result and the selection of the threshold and the wavelet function, the combination of wavelet and fft in the fault diagnosis of turbine - generator sets : by the de - noise anslysis of blocks and sin signals, concludes : to blocks signals, usually adopts soft threshold ; the law of affecting de - noise result is when use wavelet auto - de - noise, with the increasing of decomposed level, the de - noise result becomes worse while the level blow the 3, when the level above 3 and when uses wavelet packet, it is the other way round ; the best de - noise methods of the signal is that uses " dbl " wavelet function, three level, soft and " rigrsure " threshold

    本文研究了分解層數對消噪結果影響的規律和閾值、小波函數的選取，結合小波分析與fft分析診斷汽輪發電機組的故障。通過對brocks和sin兩信號的分析，得出：對blocks信號進行分析一般採用軟閾值；分解層數對消噪結果影響的規律為用小波自動降噪在分解層數小於3時，隨著分解層數的增加，消噪結果變好，反之，則變差，用小波包降噪時隨著分解層數的增加，消噪效果變好；適宜選用dbl小波軟rigrsure閾值自動消噪。
  2. Furthermore on the basis of the negative method and the sequence method for calculating the thermal parameters of steam turbine, this paper presents the combination method and this method has high accuracy and convergence

    然後，在分析汽輪機變工況熱力核算的逆序法和順序法的基礎上，引出了混合演算法，該演算法經驗算具有較高的準確性和收斂性。
  3. This essay has touched upon the following work : 1. has built up theoretic models including static mathematic models of air compressor, combustion chamber, gas turbine, waste heat recovery boiler and steam turbine which are deduced according to the feature and theory of the equipment of the object of study. upon establishment of each model based on the actual conditions, a method of multiple imitation and combination is applied to parts which have already got characteristic curves to have achieved quite accurate curves whilst the method of neural net is applied to the parts which have no characteristic curves for establishment of models

    本文進行了以下的主要工作：建立理論模型，根據對象的實際設備的特點和理論關系推導壓氣機、燃燒室、燃氣輪機、余熱鍋爐、汽輪機的靜態數學模型；根據本研究的實際情況，在建立各部件模型時，對已有特性曲線的部件，採用多項式擬合的方法，得到較為準確的特性，而對部分沒有曲線的特性，則採用神經網路的方法建立模型。
