Description
Technical field
The invention belongs to power equipment state monitoring and fault diagnosis technology field, and in particular to one kind is based on Auto-matching
Transmission line malfunction reason recognition methods.
Background technology
Transmission line of electricity tripping operation is to influence the major reason of power transformating and supplying facility reliability, and the quantity tripped caused by thunderbolt
Account for more than the 65% of 110kV and above transmission line of electricity tripping operation sum.Current each provincial power network passes through lighting location
System（Lightning locating system, LLS）Monitoring, the thunderbolt information in the range of storage region, and judged with this and
Search lightning failure point.Transmission line of electricity tripping operation, which is directly affected, to be concerned the electric power of national economy and reliably supplies.In addition, transmission line of electricity
Lightning fault it is main caused by lightning current shielding or counterattack, and the mechanism that both occurs is different, therefore safeguard procedures
It is not quite similar.
On the one hand, shielding is influenceed larger by amplitude of lightning current, earth-wire protection angle, is strikeed back by amplitude of lightning current, lightning current
The grounded screen electric resistance influence of maximum gradient and shaft tower is larger.The concrete reason type that lightning fault can not such as be judged be shielding or
Counterattack, then be difficult to instruct transmission line malfunction inquiry with formulating targetedly lightning protection measures, and then also influence the peace of power system
Full stable operation.On the other hand, though lightning location system puts into operation for many years in each provincial power network, it is only limitted to monitor in time, deposits
Thunderbolt information in the range of storage area domain, does not break through the technical bottleneck in terms of intelligent diagnostics transmission line lightning stroke failure.In view of
This, it is necessary to the relation between lightning location system data and transmission line of electricity tripping operation is deeply excavated, so as to judge identification thunderbolt event
The reason for barrier.
