Abstract
The invention discloses a kind of power network Typhoon Monitoring station points distributing method.The Typhoon Monitoring station of current meteorological department often apart from grid equipment farther out, it is impossible to react the situation of grid equipment local environment microclimate environment.The technical solution adopted by the present invention is：The wind field data near the ground of typhoon in the course of transit fine grid blockses lattice point form are obtained with meteorological analytical technology again；By the association analysis to typhoon electric network fault information in the course of transit and history Typhoon Wind Field, obtain at all typhoon electric network fault positions and fault time point average maximum wind velocity and average extreme wind speed, be used as and cause calamity air speed value；By the statistics to history Typhoon Wind Field, and power network high-voltage transmission line pole tower positional information and meteorological department's monitoring station information are combined, filtered out larger but lack the region of monitoring station as needing to lay the region of monitoring station by typhoon influence.Present invention, avoiding the subjectivity and randomness of power network Typhoon Monitoring station reconnaissance so that Typhoon Monitoring station site is representative and typicalness.
Description
Technical field
Prevented and reduced natural disasters field, especially a kind of power network Typhoon Monitoring station points distributing method the present invention relates to grid equipment.
Background technology
Typhoon be concentrated the most on the time, coverage most wide disastrous gale weather, due to grid equipment distributed pole
Extensively, influenceed larger by typhoon, therefore typhoon is one of serious threat of power network safety operation.Resisted to strengthen power network
The ability of typhoon, it is necessary to improve the design wind speed of grid equipment.But the design wind speed for improving grid equipment also leads to investment
Be significantly increased, it is therefore necessary to the rational selection design wind speed value in power grid construction and retrofit work, reach rational investment and
Balance between electric network reliability.
It is mostly directly meteorological using wind area's figure or progress engineering position in current power grid construction and retrofit work
The mode of specific analysis determines design wind speed.But these design wind speeds are based on the automatic weather station Monitoring Data of meteorological department
Obtain.In view of the factors such as the stability of site, representativeness, the convenience of plant maintenance personnel, the automatic meteorological of meteorological department
Addressing of standing is general all close to downtown areas.And grid equipment distribution is extremely wide, particularly ultra-high-tension power transmission line is generally set up in
Between high and steep mountains, away from downtown areas.Therefore the automatic weather station Monitoring Data of meteorological department is often difficult to truly reflect power network
Wind conditions at equipment present position.
In order to obtain the typhoon air monitoring data in region residing for grid equipment, it is necessary to build power network Typhoon Monitoring net
Network.Due to the limited amount of monitoring station, the necessary representative and typicalness of monitoring station addressing, and lack set for power network at present
The Typhoon Monitoring station points distributing method of standby microclimate environment so that power network Typhoon Monitoring networking is difficult to carry out.
The content of the invention
In view of this, for reasonable Arrangement power network Typhoon Monitoring station, the present invention provides a kind of power network Typhoon Monitoring station and layouted
Method.
The present invention is adopted the following technical scheme that：A kind of power network Typhoon Monitoring station points distributing method, it is comprised the following steps：
1) the typhoon observation data of history in the course of transit are arranged, obtains the wind field observation data of typhoon in the course of transit
Collection；The wind field data near the ground of typhoon in the course of transit fine grid blockses lattice point form are obtained with meteorological analytical technology again；
2) by the association analysis of electric network fault information and history Typhoon Wind Field to typhoon in the course of transit, all are obtained
At wind power grid abort situation and fault time point average maximum wind velocity and average extreme wind speed, be used as cause calamity air speed value selection
Standard；
3) by the statistics to history Typhoon Wind Field, and power network high-voltage transmission line pole tower positional information and meteorology portion are combined
Gatekeeper survey station information, filter out by typhoon influence it is larger but lack monitoring station region as need lay monitoring station region；
4) combining needs to lay the mima type microrelief environment in the region of monitoring station, selection power network Typhoon Monitoring station installation site.
Further, step 1) in, data set and typhoon yearbook data are observed with reference to wind field, with meteorological analytical technology again
Obtain the wind field data near the ground of typhoon in the course of transit fine grid blockses lattice point form.
Further, step 1) in, the horizontal resolution of the wind field data near the ground is 1km × 1km, wind near the ground
Finger 10m near the ground height in field data.
Further, step 2) detailed process it is as follows：Analyzed again by the meteorology to history typhoon, obtain power network place
Region in different typhoons maximum wind velocity (10min average maximum wind velocity) in the course of transit and extreme wind speed distribution situation；Pass through
To power network the electric power line pole tower that typhoon in the course of transit occurs fall tower, windage yaw fault data arrange, obtain power network typhoon therefore
Hinder the time occurred and geographical position；The average maximum wind velocity and average extreme wind speed of all historical failure points are calculated, cause is used as
Calamity air speed value selection standard.
Further, step 3) in, power network region is divided into grid according to 1km × 1km resolution ratio, by right
The statistics of history typhoon in the course of transit power network region wind field, obtains each grid and exceedes the wind speed frequency for causing calamity air speed value.
Further, step 3) in, with reference to power network high-voltage transmission line pole tower positional information, filter out power network location
At least there is 1 base high-voltage transmission line pole tower in domain, and from the net without meteorological department monitoring station within regional center 10km
Lattice；For the grid filtered out, statistics wherein maximum wind velocity and extreme wind speed exceed cause the calamity air speed value frequency no less than 3 times
Grid as need lay monitoring station region.
Further, step 4) in, 1km × 1km regions for needing laying monitoring station, if wherein having unnecessary 1
The shaft tower conduct of base high-voltage transmission line pole tower, then the pass landform of the local high point of prioritizing selection, lasting climb region and mountain valley
Monitoring station installation site.
Association analysis of the present invention based on regional historical Typhoon Wind Field residing for power network and power network typhoon failure, which is obtained, causes calamity wind
Speed value, and exceed with history Typhoon Wind Field the foundation for causing the calamity air speed value frequency alternatively monitoring station site；Avoid power network platform
The subjectivity and randomness of wind monitoring station reconnaissance so that Typhoon Monitoring station site is representative and typicalness.
