Example Embodiment

[0033] A calculation method for the real-time distribution model of icing on transmission lines, which includes:

[0034] Step 1. Screening of real-time weather data: Collect real-time weather observation data from meteorological stations in each province in the study area by hour, process and summarize them, and obtain weather data related to icing, including minimum temperature, average temperature, maximum temperature, precipitation Volume, average relative humidity and wind speed;

[0035] Step 2. Real-time meteorological data recognition: by analyzing meteorological conditions, find out all icing processes, and effectively identify the entire process from the beginning, growth, maintenance, interruption to the end of icing;

[0036] Step 3. Establish a real-time icing model: According to the capture coefficient of supercooled droplets and the liquid water content of the droplets, combined with the rime Kathleen.F.Jones model, a real-time icing model that considers both rain and ...

Abstract

The invention discloses a power transmission line ice coating real-time distribution module calculation method, which comprises the steps of screening real-time meteorological data; recognizing the real-time meteorological data; building a real-time ice coating model; calculating the real-time ice coating thickness of each station; performing ice coating climate condition zoning; building an ice coating trend calculation model; determining a model recurrence period; correcting the ice coating thickness; building an ice coating real-time distribution model; and deducing a final ice coating real-time ice thickness distribution diagram by zone real-time ice thickness distribution features and ice coating real-time ice thickness. The method solves the technical problems that the power transmission line ice coating trend model in the prior art does not sufficiently consider the real-time weather, so that the model cannot reach the precision required for simulating the actual ice coating condition; the ice coating information of a power transmission line cannot be mastered in real time; and the guidance on the power transmission line anti-icing and disaster reduction work cannot be realized, and the like.

Description

Technical field: [0001] The invention belongs to the technical field of icing monitoring on power transmission lines, and in particular relates to a real-time distribution model calculation method for icing on power transmission lines. Background technique: [0002] According to the research of the Meteorological Department, the "Yunnan-Guizhou quasi-stationary front" and "South China quasi-stationary front" weather systems are formed due to the southward movement of cold air in winter. The "Yunnan-Guizhou quasi-stationary front" in winter is blocked by the terrain of the Yunnan-Guizhou Plateau. The cold air from the north and south often meets and merges with the warm and humid air from the low-latitude ocean in the middle of Guizhou, forming a northwest-southeast front near the ground. , with the change of the force of cold and warm air masses, the ground front swings from the central and southwest of Guizhou to the northeast of Yunnan, forming the Yunnan-Guizhou quasi-sta...
