Technical Field

[0001] This invention relates to the field of disaster prevention and mitigation technology for power transmission lines, specifically to a method and apparatus for drawing wind speed acceleration ratio radar charts for power transmission lines. Background Technology

[0002] Due to the influence of complex surrounding terrain, the acceleration and shielding effects of winds from different directions vary greatly in mountainous transmission lines. Accurately describing the changes in tower wind speed at a specific tower location in a mountainous area under the influence of 360-degree wind flow has always been a difficult problem in determining the wind speed value for transmission line design.

[0003] As an omnidirectional scanning technology, radar images can comprehensively perceive wind speed changes under the influence of 360-degree wind direction flow, but currently it is not possible to effectively obtain radar images that can describe wind speed changes under the influence of 360-degree wind direction flow. Summary of the Invention

[0007] Step 2. Obtain the wind speed components collected from each wind speed component monitoring point within the flow field simulation analysis system;

[0008] Step 3. Based on the wind speed components collected by each wind speed component monitoring point, determine the horizontal wind speed and horizontal wind direction at each wind speed component monitoring point in the direction of the inflow wind, and output the horizontal wind speed sequence and horizontal wind direction sequence at each wind speed component monitoring point in the direction of the inflow wind.

[0009] Step 4. Determine whether the preset number of iterations has been reached. If so, obtain the horizontal wind speed sequence and horizontal wind direction sequence at each monitoring point of each wind speed component under each inflow direction and proceed to step 5. Otherwise, adjust the inflow wind direction in the flow field simulation analysis system and return to step 2.

[0010] Step 5. Determine the wind speed acceleration ratio sequence at each monitoring point of each wind speed component under each inflow direction based on the horizontal wind speed sequence at each monitoring point of each inflow direction.

[0011] Step 6. Use the horizontal wind direction sequence and wind speed acceleration sequence at each monitoring point under each inflow wind direction to draw a radar map of the wind speed acceleration ratio of the transmission line.
