Abstract

The conventional approaches to electro-magnetic transient analysis is based on the Laplace transform. This method has certain drawbacks in terms of complexity. A new technique based on the projection operator reduces computational complexity and offers the possibility of real time application. After projection onto orthogonal bases, which map to a function space related to time variable t over a given resolution, the differential equations related to the voltage and current of inductance, capacitance and transmission line transform to algebraic vector equations. By solving the vector equations, the new algorithm for transient analysis is constructed. From the results of EMTP simulations, demonstrates that the algorithms are effective and accurate.
