This paper presents an analysis of the distortion of the electric scalar potential around HVDC transmission lines. An iterative method has been developed to solve Poisson's equation for HVDC transmission line systems, accounting for the presence of space charges. The system can be in homopolar, bipolar or hybrid mode, and can include sky wires or non-corona conductors. The conductors in the bundles...
Corona discharge is a common phenomenon in high voltage transmission lines. The corona space charge arising from HVDC transmission lines is much more significant than that from HVAC lines due to the extended distribution of the space charge, which greatly influences the electric field strength on the ground and in space. A new iterative method has been developed to solve Poisson's equation for HVDC...
A comprehensive and integrated computer approach to evaluate various environmental impact parameters associated with HVAC and HVDC transmission lines is presented. The environmental parameters include: the electromagnetic fields and scalar potentials generated by the lines, and corona parameters, such as electromagnetic radiative interference, acoustic noise, and corona losses. A parametric analysis...
Summary form only given. This paper presents a comprehensive and integrated computer approach to evaluate line parameters, electromagnetic fields, scalar potentials and corona parameters associated with arbitrary configurations of parallel transmission lines and with any number and type of conductors. The electromagnetic fields and corona parameters can be computed at any location in the vicinity...
