  6. 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
