Wind-induced dynamic response simulation method for power transmission tower line coupling system

Abstract

The invention discloses a wind-induced dynamic response simulation method for a power transmission tower line coupling system, and the method mainly comprises the steps: setting an initial tower model, an insulator hanging point set and a tower wind load set, obtaining an updated tower model, and forming a tower parameter file; an assembly coordinate system is determined, the updated tower model is imported for assembly, and an assembly model file is generated; calling the tower parameter file information to calculate a ground wire spatial configuration, generating ground wire components, setting a set, and outputting a ground wire parameter file; on the basis of the assembly model, matching a set name to establish tower line interaction, and generating a tower line coupling model; specifying simulation working condition parameters, calling pole tower and ground wire parameter file information, solving pole tower and ground wire wind loads, and outputting a simulation calculation file based on set loading; and solving the simulation calculation files in batches to obtain result files under different working conditions, and extracting wind-induced dynamic response data for data analysis and docking with other three-dimensional simulation platforms.

Description

technical field [0001] The invention relates to a wind-induced dynamic response simulation method for a transmission tower-line coupling system, in particular to a wind-induced dynamic response batch simulation method of a tower-line system based on the ABAQUS secondary development technology. Background technique [0002] In order to meet the requirements of high-efficiency power transmission, the development direction of power transmission systems tends to be ultra-high voltage, long-distance cross-regional transmission, which not only requires a higher tower structure of the transmission tower, but also requires a longer span of the ground wire. While increasing the construction cost, it also further increases the difficulty of structural design and construction. [0003] The towering tower line system faces more complex wind field loads. The increase of self-weight and natural vibration period makes the structure lower and more "soft". The wind energy is mainly concentra...
