To better fit the lower amplitude P waveform, we employed two different weights for the P wave and surface wave arrivals, respectively. A grid search method was employed to find the strike, dip and slip of the earthquake that best fit the three-component records of P and surface waveforms recorded (the tangential component of the P-wave arrivals was not used). Synthetic waveforms were computed with an F-K method. Two crustal velocity models were used in the synthetic calculation to reflect a rapid east-west transition in crustal structure observed by seismic and geological studies in the study area.

为了更好地利用信号相对较弱的P波信号,对于一个地震记录,本文分别截取出P波和面波两个部分,分别给予不同的权重进行反演,结合格点搜索的方法,得到了与记录P波及面波三分量对应较好的地震的方位角、倾角和滑移角。

In accordance with the technological difficulties encountered in the process of insulation supervision based on the Dissolved Gases Analysis,several kinds of model and method are presented to improve the reliability and precision of fault diagnosis of the power transformer. Main research content includes:By deeply studying the common transformer faults diagnosing methods,such as three-ratio methods and improved electrical committee agreements,several shortcomings such as uncertainness judgment when the fault reasons,phenomenon and principles come out together while can not consistent to each other etc. For this reason,the old methods can not fully meet the need to engineering practical application.Considering fuzzy relationship matrix can fully represents the causality between fault symptoms and fault types,when diagnosing complex equipments with multiple symptoms and fault causes such as power transformer,a synthetic fuzzy diagnosing model is firstly proposed to diagnose transformers insulation faults based on DGA in this paper. Meanwhile,by further study the character of fuzzy factors,aimed at correcting the defects in classifying fuzzy sets of common fuzzy judgment,a method are put forward by unifying fuzzy synthetic diagnosis and fuzzy principle reasoning.

本文针对应用油中溶解气体分析方法进行变压器绝缘监督时所遇到的主要技术难点,提出了提高变压器故障诊断的准确性、可靠性的几种模诊断方法,主要研究内容有:通过对判断变压器故障常用的三比值法和改良电协研法的深入分析,其诊断准确率较高,但对故障原因、故障现象和故障机理间同时存在不确定性和模糊性的变压器等电气设备的故障诊断,难于满足工程应用的需要;在处理变压器等结构复杂设备的多症状、多原因故障诊断时,模糊关系矩阵可以全面反映这种症状与故障类型间的因果关系,进而提出了变压器故障诊断的模糊综合诊断模型;同时作者还深入分析了模糊算子的特性;针对常用的模糊评判结果的模糊集的集化方法的不足性,提出了将模糊综合诊断与模糊规则推理结合起来进行故障诊断的方法,能达到较好的效果。
