In recent years, nonlinear methods have attracted more and more attention and there have been some successful cases, such as median filter, mathematical morphology, etc. as a preferred way to inverstigate nonlinear numerical problems, the continued fractions method can effectively express the gradually changing data or abrupt data, so it is meaningful to study image processing by means of the continued fractions theory and algorithms
近年來在圖像處理領域，利用非線性方法進行圖像處理取得較好效果的有中值濾波、數學形態學等，非線性方法已引起越來越多研究者的重視。作為研究非線性數值問題的首選方法?連分式方法，不僅能反映數據的漸變性，也能反映數據的突變性。鑒于這些原因，本文將連分式插值和逼近引入到數字圖像處理領域，開展了圖像插值、圖像重建等方面的研究。 -
The main job of this research is : ( 1 ) analyze the operation situation of power system during faults ; pay attention to the traveling wave on the three - phase transmission line ; study the equation of voltage on three - phase transmission line with impedance capacitance coupling between phases ; contact the voltage on any point with the fault voltage, study the singularity of the voltage signal in fault point, and make it to be the base of the new fault detection method ; ( 2 ) apply the singularity detection theory based on wavelet analysis to the power system faults detection, give a complementary criterion to current fault detection criterion, study how to select the basic wavelet, how to filter noise, how to detect the singular point or fault point, and finally give a total solution. the simulations prove it to be a quick, correct and effective fault detection method
本文的主要工作有： （ 1 ）分析電力系統在發生故障時的運行狀態，尤其對三相傳輸線上的故障行波進行了分析和研究，推導了考慮相間耦合的三相傳輸線電壓方程，並將傳輸線上任一點的電壓與故障點電壓建立起聯系，得出了傳輸線上電壓信號在故障點處的奇異性，並以此作為構造新的故障檢測演算法的理論基礎； （ 2 ）將基於小波變換的信號奇異性檢測理論運用於電力系統故障檢測中，針對目前相關研究的不足，提出了電力系統故障檢測判據的補充判據，通過對基本小波的選擇、除噪措施、信號奇異點也即故障點的檢測方法所作的分析，給出了一個可行的解決方案；模擬研究表明：這是一個快速、準確、有效的故障檢測演算法。
