in this paper power system model is represented in a new domain that relates to multi-resolution analysis (mra) space. by developing mathematical model of elements in this space using galerkin method, a new alternative method for power system simulation in nonsinusoidal and periodic conditions is developed. the mathematical formulation and characteristics of new proposed space is expressed. als...

current inversion condition leads to incorrect operation of current based directional relay in power system with series compensated device. application of the intelligent system for fault direction classification has been suggested in this paper. a new current directional protection scheme based on intelligent classifier is proposed for the series compensated line. the proposed classifier uses ...

We consider the series-connected Josephson transmission line (JTL), constructed from junctions, capacitors and (possibly) resistors. calculate velocity of shocks in discrete lossy JTL. study thoroughly continuum quasi-continuum approximations to JTL, both lossless lossy. In framework these we show that compact travelling waves JTL are kinks solitons, their velocities. On top each above mentione...

In this paper, we will present a comparison between the Adomian Decomposition Method (ADM) and Taylor Matrix Method by solving some well-known partial differential equations (PDEs). In order to illustrate the analysis we examined the Telegraph equation, which is considered one of the most significant partial differential equations, describe wave propagation of electric signals in a cable transm...

This work investigates the effects of the STATCOM (Static Synchronous Compensator), a FACTS (Flexible AC Transmission Systems) device, on small-signal power system angle stability. This investigation is carried out for a single machine connected to an infinite bus via a loss-less transmission line. The study is based on investigation of the eigenvalues of the linearized power system model in th...

using new approaches to optimize the process of power transmission line routing can solve many complex problems which power transmission line routing decision-makers are faced. due to the expansion of involved parameters we can consider multi-objective evolutionary algorithms as appropriate method in this area. in this thesis with using multi-objective evolutionary algorithms nsga-ii and offere...
