Time-domain based steady-state initialization for the EMTP
… steady-state initialization algorithm in the electromagnetic transients program EMTP is based on a frequency-domain admittance method. This yields a simple, efficient solution for linear, lumped element networks. However, the basic algorithm cannot be easily extended to handle nonlinear and …

Real time simulations of EMTP results
… model of a power system is created in the Electromagnetic Transients Program (EMTP). The EMTP is an off-line program which produces transients during a fault under different operating conditions and records the three phase voltage data at two computer relay locations. The EMTP simulation …

Modeling of AC circuit breakers in the electromagnetic transients program
… a model for an A.C circuit breaker in the Electromagnetic Transients Program (EMTP). Various models for the arcing process were evaluated, and the modified Mayr equation was chosen for the model. Other equations were added to demonstrate the generality of the algorithm developed. Since the …

Modeling of industrial power distribution circuits for voltage sag and fault analysis
This thesis uses the Electromagnetic Transients Program (EMTP) to simulate sensitive electrical loads during voltage sags. The study begins by discussing the modeling procedure for induction motors based on manufacturer datasheets. It then investigates and develops a 24-pulse variable frequency …

Step by step eigenvalue analysis with EMTP discrete time solutions
… network using the nodal [G] matrix of the Electromagnetic Transients Program (EMTP) solution. This is the first time the connection between the EMTP nodal analysis solution and a corresponding state-space formulation is presented. Compared to conventional state space solutions, the nodal …

Numerical instabilities in power system transient simulations
… studies, but also in the simulation of electromagnetic transient phenomena. Because of the different structure of the two sets of equations, computational efficiency can be improved if both sets of equations are solved separately, with the result from one set of equations showing up in …

Frequency dependent impedance of stranded conductors using the subdivision method
… this thesis project has been to write a computer program that calculates the resistance and inductance of stranded conductors in the indicated frequency range. The fundamental idea in the implemented technique is to subdivide the cross section of each strand with circular and straight line …
