Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0020] Such as figure 1 As shown, the query method of power grid equipment in high wind speed areas based on Doppler radar radial wind speed can be developed and executed by Java software program, which specifically includes the following steps:

[0021] Step 1: Execute the Java program regularly. Since the Doppler radar scan cycle is 6 minutes, this program is executed every 6 minutes, which can realize real-time identification of areas with high wind speed. Obtain Doppler radar radial wind speed data from the meteorological disaster monitoring database system. Each radial wind speed data has multiple latitude and longitude coordinates. Each latitude and longitude coordinate corresponds to a r...

Abstract

The invention discloses a high-wind-speed area power grid equipment query method based on Doppler radar radial wind speed. The method solves the technical problem that a high-wind-speed area is difficult to recognize in the prior art, and accordingly power grid equipment greatly influenced by gale can not be inquired and gale disaster analysis of the power grid equipment can not be carried out. Through a series of procedures such as extraction of Doppler radar radial wind speed data, clustering, high-wind-speed area synthesis and power grid equipment query, original discrete coordinate data are converted into high-wind-speed area information, a reliable and accurate power grid high-wind-speed area reorganization method is provided, the power grid equipment greatly influenced by the gale is finally inquired, and professional personnel are helped to analyze influences of gale disasters on the power grid equipment.

Description

technical field [0001] The invention relates to a query method for power grid equipment in a high wind speed area based on Doppler radar radial wind speed, and belongs to the technical field of power grid meteorological environment analysis. Background technique [0002] The power industry is an industry with high meteorological sensitivity and high demand. Its production, construction, and operation are greatly affected by meteorological environmental factors. It is necessary to analyze the relationship between meteorological factors and equipment failures and reduce the impact of meteorological disasters on the normal operation of power grid equipment. It is a research hotspot in the industry in recent years and plays a vital role in building a strong power grid. [0003] At present, the correlation between meteorological factors and power grid equipment is mainly analyzed based on the real-time data of ground automatic observation stations. Although the observation statio...
