Technical field
The present invention relates to distribution network line fault to monitor field, and in particular to a kind of distribution network failure indicator.
Background technology
Most of existing fault detector is equipped with the function of telecommunication, reports position of failure point, faulty line
And the fault message such as fault time.At present, application of the GPRS communications in fault detector is very ripe.Although use
Telecommunication schemes of the GPRS as fault detector, it is convenient to have, it is simple the characteristics of, but the program also have it is larger not
Certainty and unreliability.First, GPRS communication capacity and the rate of load condensate of the origin base station are related, if the origin base station load
Rate is heavier, then is likely to that the communication information can not be transmitted in time;Secondly, GPRS communications need to pay not to second party Office of the Telecommunications Authority every year
Luxuriant and rich with fragrance communication cost;In addition, in the not good enough mountain area of some signals, also tend to not sound feasible using GPRS as telecommunication scheme
Border.And the caused data deficiency self-described in communication process, the integrated level of electrical power distribution automatization system is reduced, adds and is
The configuration debugging efforts and implementation management cost of system.Very big be stranded is brought to electrical power distribution automatization system construction and the integrated of system
It is difficult.
IECTC57 issues IEC61850 standards, and the standard makes the intelligent electronic device from different vendor in transformer station
（IED）Interoperability is realized, present IEC61850 has been widely used in electric substation automation system.The standard employs face
