采用双线刚性连接加固方案，施工简单易行，对原钢件损伤小，安全系数高，加固费用低，减振效果明显，各项测试结果基本满足《铁路桥梁检定规范》及提速技术要求，因此对确保列车通过大桥安全及京广线的整体提速具有十分重要的意义。 - 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 )分析电力系统在发生故障时的运行状态，尤其对三相传输线上的故障行波进行了分析和研究，推导了考虑相间耦合的三相传输线电压方程，并将传输线上任一点的电压与故障点电压建立起联系，得出了传输线上电压信号在故障点处的奇异性，并以此作为构造新的故障检测算法的理论基础； ( 2 )将基于小波变换的信号奇异性检测理论运用于电力系统故障检测中，针对目前相关研究的不足，提出了电力系统故障检测判据的补充判据，通过对基本小波的选择、除噪措施、信号奇异点也即故障点的检测方法所作的分析，给出了一个可行的解决方案；仿真研究表明：这是一个快速、准确、有效的故障检测算法。
