Abstract

The invention provides an anti-oscillation arrangement and configuration method for phase-to-phase spacers of an ultrahigh-voltage compact power transmission line. In the anti-oscillation arrangement and configuration method for the phase-to-phase spacers of the 1,000kV ultrahigh-voltage compact power transmission line, a conducting wire-insulator string-phase-to-phase spacer coupling finite element model is established for the 1,000kV ultrahigh-voltage compact transmission line by utilizing a finite element analysis method, the influence of first-order to sixth-order wavelengths in oscillation is taken into full account, and simulative computing and analysis are performed on the oscillation and oscillation suppression of the power transmission line according to factors such as different spans, weather conditions comprising different ice coating thicknesses and wind speeds, and the like of the power transmission line. The method can be used for guiding the anti-oscillation work of the 1,000kV ultrahigh-voltage compact power transmission line, and a technical support is provided for the secure and stable running of a power grid.

Description

technical field [0001] The invention relates to the field of prevention and control of transmission line faults, in particular to an anti-galling installation and configuration method for ultra-high voltage compact transmission line spacer bars between phases. Background technique [0002] With the rapid development of my country's social economy, the demand for electricity presents a trend of rapid growth. From the perspective of power grid construction and UHV power grid planning, the number of lines continues to increase, and the tension of power transmission line corridors may become the main factor affecting power grid construction in many areas. Compared with conventional power transmission technology, compact power transmission technology has the characteristics of reducing power transmission costs and reducing the land occupation of power transmission corridors. One of the methods. Compared with conventional lines, the phase-to-phase distance of compact transmissio...
