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。 -

Based on the results, chapter 3 obtains the necessary and sufficient conditions of the positive line a - doubly diagonally dominant matrices being non - singular m - matrices, by means of the nature of the associated digraph of matrices irreducible and weakly irreducible matrices. the results obtained simplify the process of judgment, only making us to check the related quantity involved in the circuit of the associate digraph of matrices
第三章在已有結果的基礎上，藉助于矩陣的伴隨有向圖、不可約以及弱不可約矩陣的性質，得到了正線-雙對角占優矩陣為非奇異m -矩陣的充分必要條件，所獲結果簡化了判定過程，只需要對矩陣伴隨有向圖圈中所涉及到的相關量進行驗證即可。
