Galloping Computation and Analysis for Long Multi-span Bundle Conductors of Power Transmission Lines;

The relation between geometric parameters of bundle conductor for UHVAC transmission line and the maximum power frequency electric field gradient on ground as well as the characteristic of the maximum power frequency electric field gradient on ground are studied; and the minimum heights of conductors above the ground and the widths of corridors for two basic conductor arrangements are given.

Since large section and split conductor with big ratio of aluminum and steel is adopted in new power transmission lines in China, the conductor wave is easy to produce.

Sarma method was improved by introducing bundled conductors and then used to calculate the electric field intensity generated by unipolar high voltage direct current(HVDC) transmission lines,and the influences of configuration parameters were also analyzed.

A new finite element with two nodes and eight degrees of freedom is developed for simulating three dimensional free vibrations of bundled conductors.

Comparing the caculation errors among 3 caculation methods for the surface electic filed, this paper applies charge simulation method to caculate the surface electric field along ±800 kV DC transmission lines with bundled conductors.

Calculation and characteristic analysis of surface voltage gradient for UHV transmission conductor bundle;

Effects of structure parameters (such as the number of conductors in a bundle, cross-section of sub-conductor, conductor splitting spacing, conductor bundle height and pole spacing) of ±800kV DC transmission lines on the total electric field, the ion current density, the audible noise and t.

Aiming at the vibration phenomenon of split conductors in high-voltage overhead transmission lines,synthesizing the domestic and international research and experimental analysis,this paper expatiates the main vibration types,reasons and dangers of the split conductors,and puts forward the corresponding countermeasures.
