A Novel Electro-magnetic Transient Analysis Method for Distributed Parameter Transmission Lines

摘要：

A novel electro-magnetic transient analysis technique by means of the orthogonal projection method for power system is proposed. Due to the approach criterion, the telegraph equation of the transmission line can be approximated to be the linear combination of a certain set of orthogonal basis, for example, the Daubechies basis. After projection onto orthogonal bases, which map to a function space relates to time variable t over a given resolution, the differential equations related to the voltage and current of transmission line transform to algebraic vector equations, based on which the projected equivalent models of each unit can be obtained. Then, the transients of the transmission system can be computed in the projection domain accordingly. EMTP simulation tests are presented which validate the method described.
