Power grid typhoon monitoring station distribution method

Abstract

The invention discloses a power grid typhoon monitoring station distribution method. Currently, typhoon monitoring stations of the meteorological department are generally far away from power grid equipment and cannot reflect conditions of a micrometeorological environment where the power grid equipment is located. According to the technical scheme, a meteorological reanalysis technology is adopted to obtain near-surface wind field data in a refined meshed grid point form in a typhoon pass-over period; through association analysis on power grid fault information in the typhoon pass-over period and historical typhoon wind fields, an average maximum wind speed and an average extreme wind speed at all typhoon power grid fault positions and fault time points are obtained to serve as disaster-caused wind speed values; and a region which is seriously affected by a typhoon and is short of a monitoring station is screened out to serve as the region needing arrangement of a monitoring station through statistics on the historical typhoon wind fields in combination with position information of power grid high-voltage transmission line towers and monitoring station information of the meteorological department. Through the method, subjectivity and randomness of selection of a power grid typhoon monitoring station are avoided, and the location of a typhoon monitoring station is representative and typical.

Description

technical field [0001] The invention relates to the field of disaster prevention and reduction of power grid equipment, in particular to a method for arranging typhoon monitoring stations of a power grid. Background technique [0002] Typhoon is the disastrous windy weather with the most concentrated time and the widest range of influence. Because the power grid equipment is widely distributed and greatly affected by typhoon, typhoon is one of the serious threats to the safe and stable operation of power grid. In order to enhance the power grid's ability to withstand typhoons, it is necessary to increase the design wind speed of the power grid equipment. However, increasing the design wind speed of power grid equipment will also lead to a substantial increase in investment. Therefore, it is necessary to choose a reasonable design wind speed value in the construction and renovation of the power grid to achieve a balance between reasonable investment and grid reliability.

AI Technical Summary

Problems solved by technology

Due to the limited number of monitoring stations, the site selection of monitoring stations must be representative and typical. At present, there is a lack of typhoon monitoring station layout methods for the micro-meteorological environment of power grid equipment, which makes it difficult to carry out the construction of typhoon monitoring networks in power grids.
