Problems solved by technology

For a long time, regional wind speed measurement data have been provided by local weather stations, but micro-topography can produce wind speed acceleration effects, and the use of wind speed data from weather stations has certain limitations; measuring wind speed by manually going to the top of the mountain requires a lot of manpower and material resources In addition, there is a certain risk

Abstract

The invention discloses a bealock type microtopography mountain top wind speed intelligent measurement method comprising the following steps: collecting an original image of a bealock type microtopography with a pre-measured wind speed, and carrying out intelligent image identification processing so as to obtain topographic parameters of the bealock type microtopography; combining the existing wind speed value data of the bealock type microtopography area with topographic parameters of the bealock type microtopography where the power transmission line is located, and fitting an H / R mountain top wind field equation; and combining the topographic parameters obtained through image recognition with a bealock type micro-topography mountain top wind field equation to obtain the bealock type micro-topography mountain top wind speed for establishing the power transmission line. The method is convenient to use and low in cost, necessary data can be provided for safety design when the power transmission line passes through the bealock type microtopography, and safe and stable operation of the power transmission line is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of safe operation of power transmission lines, in particular to an intelligent measurement method applied to the wind speed at the top of a pass-type micro-topography. [0002] technical background [0003] With the rapid development of power grid construction, line corridors are becoming more and more tense, more and more transmission lines pass through areas with complex terrain and harsh weather conditions, and the problem of safe operation of lines is becoming more and more serious. When the transmission line passes through the pass-type micro-terrain, the transmission tower is often erected on the top of the mountain, and the pass-type micro-terrain mountain top is prone to local strong winds, which will cause the insulator strings and wires of the transmission line to swing out of the plane, and wind flashover accidents will occur , the success rate of reclosing after wind deflection tripping is low, which seriou...
