One way is that the rail lines for high speed are built and the high speed trains are applied. the other way is that the existing railways are improved and the tilting trains are used. besause the tilting train can ensure the ride quality of passengers, improve the speed of curving and reduce the time on trip meanwhile and do not need too much cost the second way is accord with the situation of our country and railway
列車提速有兩種途徑：一種是修建高速鐵路開行高速列車，另一種是對既有線加以改造，開行擺式列車。其中，擺式列車在保證旅客乘坐舒適性的同時，能夠提高列車曲線通過的速度，縮短旅行時間，而又不需要太大的投資，符合我國的國情、路情。 -
The recursive criterion of transient current protection based on mallat wavelet transform is presented in order to meet the real - time demands. the reserch shows deficiency existed in the prevenient principle of transient current protection, so a new improved scheme of transient current protection is proposed. the characteristics of transient protection at different bus distribution capacitance is also analysed in this thesis. the study shows that operate of transient protection is correct when the bus distribution capacitance change. other conclusion include : the trip of transient protection must be locked when the power circuit breaker of transimission line operated, because the trip is incorrect at this time ; the features of transient current and it ' s energy is different between the fault and thunder over - voltage in transimission line, and them can be identified ; the ratio of high frequency component of current in serise capaciters compensation line, svc and hvdc system is far little than fault transient current, so all of them do not affect the working of trasient current protection
應用功率譜估計方法討論了故障高頻暫態噪聲信號在頻率軸上的分佈情況，利用功率譜分析結果實現的非參數化系統辨識方法研究了母線分佈電容對電流高頻暫態信號的衰減特性。論文的後半部分（第五，六，七章）著重分析了現有基於故障電流的暫態保護原理和判據存在的問題，提出了新的實現方案，並討論了暫態電流保護的運行性能。利用多分辨分析和小波分解快速演算法構成的遞推暫態保護判據，可以準確區分故障線路和非故障線路，實現超高速暫態電流保護，計算更為簡單方便，計算速度更快。
