The TLM model of 3 - phase pow er t ran sm ission line is developed. Appling the transmission line modeling (TLM) method to analysis 1000kV ultrahigh voltage( UHV) AC transmission line, the obtained results prove that it is economical and reasonable to transmit the natural power by power transmission, and the transmission lines is a long-distance transmission power ; but both the super power and the power transmission, the transmission power reduce with the increase of transmission distance.

Abstract:
The transmission line modelling (TLM) method is briefly discussed, showing how lumped dynamic components can be represented by equivalent lines. A hydraulic position control system was modelled by the TLM method, requiring mechanical and fluid transmission line models and a special ‘integrator’ line. The theoretical responses to step inputs are compared with experimental ones. Good agreement is shown.

Abstract:
Position sensorless control has been widely used in permanent magnet synchronous motor (PMSM) drives in low-cost applications or in the fault-tolerance control of position sensors. Conventional sensorless control methods often adopt a back electromagnetic force (EMF)-based position observer, which results in bandwidth reduction in signal processing and lower estimation accuracy. This paper introduces a numerical solution based on transmission line modeling (TLM) to obtain the back EMF. The TLM method is used for the numerical calculation of electromagnetics due to the clear algorithm structure

The theme of this thesis is concerned with the modelling of the multi-physics interactions that occur in lightning and arc discharge. The main contributions of this research are presented as combining different physical studies namely, electromagnetic (EM) propagation, thermal diffusion and non-linear materials using a numerical algorithm. The algorithm was developed based on the two dimensional (2D) numerical transmission line method (TLM). The algorithm was applied to several practical examples namely, to model the electro-thermal analysis and the temperature development in a plasmonic nano-

The Transmission Line Matrix (TLM) numerical algorithm, based on the discrete Huygens' principle, has been extensively used to solve electromagnetic structure problems. The major advantage of this method is its simplicity and flexibility as the vectorial Maxwell's Equations are transformed into a simple numerical model of digital signal processing system.

New developments of Absorbing Boundary (AB) Algorithms for the Transmission Line Matrix (TLM) Method have been presented in this thesis. A new approach has been proposed to obtain the optimized Dissipation Absorbing Boundary Condition (ABC). In this approach, optimization is performed directly on the structure being studied. This approach has been implemented in 2D and 3D TLM. It shows its great advantage especially in 3D because it is unconditionally stable while many other approaches such as extrapolation approach, are unstable. Great efforts have also been made in implementing Liao's ABC in

Longitudinal defects, including stress-corrosion cracking (SCC) and selective seam weld corrosion, can occur in natural gas transmission pipelines. Previously developed nondestructive testing techniques (including angle beam ultrasonics, electromagnetic acoustic transducers (EMATs), and remote field eddy current) are capable of detecting longitudinal defects. Two angle beam ultrasonic syatems are commercially available, and an EMAT system is being commercialized. But there are factors that limit the applicability of these techniques, such as minimum pipe diameter and maximum inspection speed.

Prior research leading to the development of predictive electromagnetic coupling computer codes has shown that the coating conductance is the principal factor in determining the response of a pipeline to magnetic induction transmission line. Under power line fault conditions, a high voltage may stress the coating causing a significant change in its conductance, and hence, the coupling response. Based upon laboratory experimentation and analysis, a model has been developed which allows prediction of the modified coating characteristics when subjected to high voltages during fault situations.

Abstract:
External coatings are used routinely to protect transmission pipelines from conditions that promote corrosion. However, over time coatings may disbond, allowing corrosion to occur. To detect metal loss due to corrosion defects, transmission pipeline operators often use magnetic flux leakage (MFL) in-line inspection tools. These tools do not detect the cause of an actual problem, i.e., failure of a coating and the presence of a corrosive environment; rather, they detect only the result, i.e., a defect that may permanently alter the pressure capacity of the pipeline.

A SIMPLE METHOD FOR A RELIABLE MODELLING OF THE NONLINEAR BEHAVIOUR OF BOLTED CONNECTIONS IN STEEL LATTICE TOWERS. The Hong Kong Institute of Steel Construction, 2022. http://dx.doi.org/10.18057/ijasc.2022.18.1.6.

Abstract:
The behaviour of bolted connections in steel lattice transmission line towers affects their load-bearing capacity and failure mode. Bolted connections are commonly modelled as pinned or fixed joints, but their behaviour lies between these two extremes and evolves in a nonlinear manner. Accordingly, an accurate finite element modelling of the structural response of complete steel lattice towers requires the consideration of various nonlinear phenomena involved in bolted connexions, such as bolt slippage. In this study, a practical method is proposed for the modelling of the nonlinear response o
