Abstract

The invention relates to the technical field of electrical engineering, discloses a microtopographic region wind power plant icing prediction method and system, and aims at solving the technical problems that in the prior art, a wind generating set is low in output, and the wind power output cannot be accurately predicted. The method comprises the following steps: acquiring basic information dataof each wind turbine generator in a to-be-analyzed wind power plant, and calculating first meteorological information data of each wind turbine generator in a future set time; matching the basic information data of each wind turbine generator with a judgment condition of the microtopography type, and determining the microtopography type to which each wind turbine generator belongs; calculating second meteorological information data of each wind turbine generator according to the microtopography type of each wind turbine generator, and correcting the first meteorological information data by adopting the second meteorological information data; and calculating the icing condition of each wind turbine generator according to the corrected first meteorological information data.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a method and system for predicting ice coverage of a wind farm in a micro-topography area. Background technique [0002] Fossil energy such as coal and petroleum can easily cause serious damage to the ecological environment. In recent years, new energy power generation has developed rapidly, and the number of wind farms has increased significantly, becoming the main force of new energy power generation. However, since wind farms are mostly located on ridges, mountaintops and other places with high altitude micro-topography, the temperature is relatively low and the humidity is relatively high, so the blades of wind turbines are easily covered with ice. Once the fan blades are covered with ice, the performance of the wind turbine blades will change, which will reduce the output of the wind turbines. When the blades rotate, the ice may fall off and cause safety accid...
