Abstract

The invention provides a device for determining the length of the peripheral flow field in the simulation analysis of the micro-topographic wind field. The device includes: a peak shape determination module for determining the shape of each peak in continuous peaks; Analyze and determine the wind speed at multiple wind speed monitoring points set above each mountain peak; the similarity coefficient determination module is used to sequentially determine the similarity coefficient of the wind speed profile between two adjacent peaks according to the wind speed at each wind speed monitoring point; the peripheral flow field The length determination module is used to determine the sum of the distances between the previous peak of the two adjacent peaks and the distances between the previous peaks in the direction of continuous peak arrangement as the length of the peripheral flow field when the similarity coefficient is less than or equal to the convergence tolerance. The invention is convenient for wind field simulation analysis, is beneficial to computer calculation, effectively improves the accuracy of peripheral flow field length calculation, and is suitable for both simple terrain and complex terrain.

Description

technical field [0001] The invention relates to the technical field of disaster prevention and mitigation for power transmission and distribution equipment, in particular to a device for determining the length of a peripheral flow field in the simulation analysis of a micro-topographic wind field. Background technique [0002] With the continuous improvement of computing power of computer hardware and software, the application of fluid simulation analysis to obtain the characteristics of wind field in micro-topographic regions is becoming more and more easy to realize. In the fluid simulation analysis, since the real profile at the inflow boundary of the micro-topography area cannot be known, it is usually assumed that the incoming wind velocity profile at infinity obeys the wind velocity profile curve obtained by using the power exponent rate method under the A-D landforms. After the wind passes through several peaks, the wind speed profile is basically stable, and the wind...
