中文摘要	Traditional travelling wave differential protection cannot be applied to series compensated transmission lines because of the voltage changes on the capacitor. This paper presents an analysis of the propagation of travelling wave on series compensated lines, especially studies the fault characteristics of the initial wave. The results show that the key travelling wave fault information, the wave front information, is unaffected by the series capacitor bank for metal oxide varistors (MOV) as well as other capacitor types. Based on it, a new differential protection based on the wavelet transform has been proposed. The method uses only the wave front information, so it is suitable for series compensated lines. Electric magnetic transient calculation program simulations demonstrate the validity of the protection method.
