Background technology
Along with the develop rapidly of national economy, how to guarantee the circuit on power system security of operation, become the emphasis problem of R﹠D institution and business research.Because China's electrical network is staggered complicated, it is wide to distribute, thereby be subjected to the influence of mima type microrelief, micro climate big, power circuit ice damage accident takes place again and again, the transmission line of electricity that repeatedly occurs in most of area, China south is influenced by cryogenic freezing to cause large tracts of land to fall tower, power outage, causes heavy losses to national economy.At present owing to lack effective monitoring, cause the lead of power circuit causes shaft tower, gold utensil under serious ice coating state bearing load its scope of design and cause that shaft tower collapses head and shoulders above to the power circuit icing.
Power department is selected heavy icing area in order to understand the icing situation of power circuit at present, sets up the artificial observation station, set up simulation shaft tower and lead, when awful weather caused analog conducting wire to freeze, the observation personnel measured ice thickness, and fuzzy circuit icing situation this moment of calculating, for further deicing provides foundation.
Method with simulation ice thickness reckoning actual track ice thickness has following shortcoming:
Data are inaccurate.At first, on power circuit, each shaft tower present position meteorological condition is inconsistent, cause in the shaft towers at different levels insulator chain and wire icing difference in thickness bigger, the simulation ice covering thickness can only reflect near the ice covering thickness the observation station, can not represent the actual ice thickness of lead between shaft tower upper conductor and the shaft tower span.Because the temperature of lead when charging operation is different with the temperature of analog conducting wire, therefore will simulate ice thickness is directly used in and carries out computational analysis in the actual track, whether missing by a mile of gained result and the actual ice coating load of circuit, can only give needs artificial deicing that inaccurate reference information is provided.
Reaction velocity is slow.China's transmission line of electricity is intricate, and distribution is wide and the northern area duration in winter is longer, if set up the research station at each heavy icing area, sends special messenger's field monitoring, will expend great amount of manpower and material resources, financial resources.Artificial observation is the one-point measurement data regularly, can't in time feed back the related data of ice trouble.
