Transient protection uses transient fault components to realize the protection,and it has a high speed。Started from theory of wavelet analysis and transient protection,several aspects of transient protection are displayed in this thesis。They are:acquainting with the basis principle of transient protection;selecting out the simulation tools and the wavelet function; wavelet analysis and artificial neuron nets applied in transient protection;additional analysis about some influencing factors;theory of fault phase selection using wavelet analysis and gaining the simulation data of fault in transmission line under every fault condition by ATP。...
