Book Description
Corona performance is an important consideration in electrical design and operation of high-voltage AC and DC transmission lines. The choice of conductors is based primarily on the environmental impact aspects of corona performance. Increasingly higher transmission voltages in modern electric power systems has led to considerable amounts of research on different aspects of corona performance of transmission lines. This book brings together research and covers, physical, analytical and engineering aspects of corona performance of both AC and DC transmission lines.

Book Description
Complete coverage of power line design and implementation "This text provides the essential fundamentals of transmission line design. It is a good blend of fundamental theory with practical design guidelines for overhead transmission lines, providing the basic groundwork for students as well as practicing power engineers, with material generally not found in one convenient book." IEEE Electrical Insultation Magazine Electrical Design of Overhead Power Transmission Lines discusses everything electrical engineering students and practicing engineers need to know to effectively design overhead power lines. Cowritten by experts in power engineering, this detailed guide addresses component selection and design, current IEEE standards, load-flow analysis, power system stability, statistical risk management of weather-related overhead line failures, insulation, thermal rating, and other essential topics. Clear learning objectives and worked examples that apply theoretical results to real-world problems are included in this practical resource. Electrical Design of Overhead Power Transmission Lines covers: AC circuits and sequence circuits of power networks Matrix methods in AC power system analysis Overhead transmission line parameters Modeling of transmission lines AC power-flow analysis using iterative methods Symmetrical and unsymmetrical faults Control of voltage and power flow Stability in AC networks High-voltage direct current (HVDC) transmission Corona and electric field effects of transmission lines Lightning performance of transmission lines Coordination of transmission line insulation Ampacity of overhead line conductors

Book Description
This book has two purposes. The first is to examine the electromagnetic theory behind many of the calculations relevant to the design of high voltage overhead transmission lines. These include electromagnetic propagation on multiple parallel wires above the earth and their associated fields, electrostatic fields near more complicated geometries, limitations on power transfer capability, corona onset and its effects, electromagnetic compatibility with other systems that share the transmission line right of way and grounding systems. The second is to show how the more general theory reduces to the theory commonly used by practicing engineers. This includes understanding both the physical and mathematical approximations made for simplified analysis. In describing these, some practical aspects of designing high voltage transmission lines are discussed. Included are discussions of why common transmission line topologies are used, the relation between electric fields and many design parameters, ampacity and sag calculations, and techniques for increasing power transfer capability. In the second edition of the book additional material has been added to help the reader understand why overhead lines are used, why they are designed the way they are and how they interact with systems that share the right of way.

Book Description
Electric utilities are exploring new technologies to cope up with the in-crease in electricity demand and power transfer capabilities of transmission lines. Compact transmission lines and high phase order systems are few of the techniques which enhance the power transfer capability of transmission lines without requiring any additional right-of-way. This research work investigates the impact of compacting high voltage transmission lines and high phase order systems on the surface electric field of composite insulators, a key factor deciding service performance of insulators. The electric field analysis was done using COULOMB 9.0, a 3D software package which uses a numerical analysis technique based on Boundary Element Method (BEM). 3D models of various types of standard transmission towers used for 230 kV, 345 kV and 500 kV level were modeled with different insulators con-figurations and number of circuits. Standard tower configuration models were compacted by reducing the clearance from live parts in steps of 10%. It was found that the standard tower configuration can be compacted to 30% without violating the minimum safety clearance mandated by NESC standards. The study shows that surface electric field on insulators for few of the compact structures exceeded the maximum allowable limit even if corona rings were installed. As a part of this study, a Gaussian process model based optimization pro-gram was developed to find the optimum corona ring dimensions to limit the electric field within stipulated values. The optimization program provides the dimen-sions of corona ring, its placement from the high voltage end for a given dry arc length of insulator and system voltage. JMP, a statistical computer package and AMPL, a computer language widely used form optimization was used for optimi-zation program. The results obtained from optimization program validated the industrial standards.
