Transmission expansion planning based on merchandizing surplus of transmission lines
This paper proposes an optimal transmission expansion planning (TEP) which is based on determining share of each line in merchandizing surplus (MS) of system, determining by Independent System Operator (ISO). The more share of a line in MS of system denotes the priority of a line for expansion. The procedure of determining MS of each line in a power system is based on determining the MS share o...
متن کاملDesign of a Wireless Sensor Module for Monitoring Conductor Galloping of Transmission Lines
Conductor galloping may cause flashovers and even tower collapses. The available conductor galloping monitoring methods often employ acceleration sensors to measure the conductor translations without considering the conductor twist. In this paper, a new sensor for monitoring conductor galloping of transmission lines based on an inertial measurement unit and wireless communication is proposed. A...

متن کاملPerturbation-based Finite Element Analyses of Transmission Line Galloping
Efficient perturbation schemes are developed to compute the large amplitude, low frequency, galloping vibrations of a multi-span, overhead transmission line. Systematic procedures are formulated to assess the stability of a conductor’s wind and ice loaded static profile by employing a multiple-degree-of-freedom finite element model. The use of the computationally most demanding part of the fini...
متن کاملFinite Element Modelling of Transmission Line Galloping
A computationally efficient, finite element idealization is presented to analyse galloping, which is characterized by large amplitude vibrations of iced, multi-span, electrical transmission lines. A three-node, isoparametric cable element having three translational and a torsional degree-of-freedom at each node is developed to model a conductor. Support insulator strings and remote conductor sp...
