Abstract

The invention discloses a data interpolation method and apparatus. The method comprises: obtaining multiple first data and multiple second data within a target time period, wherein the first data is data measured by a wind measurement tower, and the second data is meteorological analytical data; establishing a target network model according to the first data and the second data; and obtaining target data by calculation according to the target network model, wherein the target data is data that needs to be interpolated in wind measurement data within the target time period. According to the method and the apparatus disclosed by the invention, the technical problem of inability to obtain missing wind measurement data by using relevance of contiguous available data in time and space in the prior art caused by long-time data missing is solved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a data interpolation method and device. Background technique [0002] In the pre-construction of wind power, it is necessary to set up a wind measuring tower in the target construction area to observe the weather conditions for no less than one year, and then evaluate the wind resources in the target construction area based on the observation data to determine whether the area has development value. Development value, how to carry out engineering design, especially how to design the layout of wind turbines to maximize economic benefits. The observation process (hereinafter referred to as wind measurement) plays a vital role in the construction of wind farms and the realization of economic benefits. However, in the continuous wind measurement for not less than one year, the wind measurement data are often incomplete due to environmental reasons such as severe weather, freez...
