Embodiment

[0113] The tower type of the shared tower is selected from the common typical 110kV cat head tower, the tower height is 20m, L200 angle steel with a width of 0.2m is used, and 3 base station antennas are installed. The base station antenna model is DB878G65A-XY, the operating frequency is 960MHz, the power is 10W, and it is modeled according to parameters such as real size. Taking the center of the bottom of the shared tower as the origin of the coordinate system, establish such as Figure 4 In the Cartesian coordinate system (X, Y, Z) shown, the coordinates of the center points of the base station antennas T1, T2 and T3 are (5,-5,15), (5,5,15) and (-5,5, 15), the coordinate unit is m, the incident plane wave frequency of the station is 0.3-3GHz, the amplitude is 1V / m, the incident is from the direction of 0° of the negative semi-axis of the Y-axis, and three different receiving stations are selected, namely the observation point r. The coordinates are (0,1500,2), (0,2000,2) a...

Abstract

An accurate solution method for the passive interference of shared iron towers, which establishes the scatterer model and incident field model in the problem of shared iron tower passive interference; according to the scatterer model and incident field model obtained in step 1, the second-order coupled scattering post-shared Boundary conditions on each scatterer of the tower, and simultaneous boundary conditions, and then solve the equivalent source under the coupling background; according to the solution of the equivalent source under the coupling background, establish the total scattering field equation formed by each scatterer unit, and solve The scattering field when there is a shared iron tower, so as to realize the solution of the passive interference of the shared iron tower. The invention can be used to accurately solve the passive interference level of shared iron towers, lays a theoretical foundation for subsequent research on passive interference of shared iron towers, and is of great significance for solving passive interference of existing transmission lines.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility of high-voltage power transmission and transformation projects, in particular to an accurate solution method for passive interference of a shared iron tower. Background technique [0002] The growing number of transmission lines has created an increasingly prominent problem of passive interference to adjacent radar stations. In particular, shared towers, as a new product under the "sharing economy" model, have developed rapidly in transmission lines. However, since the shared tower directly installs a base station antenna that continuously transmits high-frequency communication signals on the transmission tower, the excitation source and electromagnetic scatterer model in the problem of passive interference of the traditional transmission tower to the adjacent radio station are changed, resulting in transmission lines. Passive interference mechanisms and interference results...
