Description
Technical field
The present invention relates to a kind of power distribution networks based on multi-source data to stop monitoring method of sending a telegram in reply.
Background technique
Stop the critical reliability index that telegram in reply statistics is power distribution network operation, power distribution network, which stops telegram in reply monitoring, to be intuitive to see
The degree of reliability of operation of power networks is of great significance to distribution Analysis of Isolated Net Running.
Power distribution network, which mainly integrates power distribution network scheduling Dispatching Control System and automates, at present stops send a telegram in reply message, production management system
Outage information data carry out stopping telegram in reply statistics.Since there are dispatchers to omit switch set, terminal frequency in generating operational process
Numerous shake, have a power failure in short-term do not issue outage information, disaster during outage information publication not in time or do not issue and (big rule occur
When mould power-off event, outage information can postpone to issue；Allow not issue outage information during disaster) phenomena such as, cause
Stop telegram in reply and count generally existing deviation, can not ensure accuracy, real-time and the integrality of the data statistics that stops sending a telegram in reply.
System obtains power-off event data source at present, is broadly divided into two kinds:
(1) power distribution network Dispatching Control System pushes in real time power failure, telegram in reply message
Stop sending a telegram in reply message data comprising conjugating switch ID, switch changed position information (divide/close), switchtype (incoming switch/dry
Wiretap/branch's wiretap), whether be that feeder line ID, switch changed position belonging to remote motion signal, displacement switch influence distribution transforming information etc..
(2) production management system timing updates outage information
Production management system can be by information such as newest Trouble ticket, plan list, power failure distribution transformings, and timing (frequency 5 minutes) is more
Newly into ORACLE middle database, system can take out newest information, carry out data check work.
Based on power distribution network scheduling controlling need to provide push in real time stop sending a telegram in reply message, production management system outage information stop it is multiple
Fault outage range and scheduled outage range in the message that stops sending a telegram in reply cannot be distinguished in electricity statistics, for automating scope of power outage accuracy
Lack verification, and will appear information not in time, the problems such as failing to report, it is impossible to meet the requirements of power distribution network information security.
For existing power distribution network scope of power outage analysis there are deviation, fail to report, report the problems such as, the present invention fusion multi-source number
According to the addition technologies such as fault outage and scheduled outage division, data accuracy verification, missing data amended record improve power distribution network and stop
Accuracy, real-time and the integrality of telegram in reply data statistics.
Summary of the invention
The purpose of the present invention is to provide a kind of power distribution networks based on multi-source data to stop monitoring method of sending a telegram in reply, this method fusion
Multi-source data, addition technologies, the raising such as fault outage and scheduled outage division, data accuracy verification, missing data amended record are matched
Accuracy, real-time and the integrality of grid power failure telegram in reply data statistics.
To achieve the above object, the technical scheme is that a kind of power distribution network based on multi-source data stops telegram in reply monitoring
Method includes the following steps,
S1, multi-source data obtain:
It accesses power distribution network Dispatching Control System, production management system and applies acquisition system, include stopping telegram in reply letter to obtain

S2, fault outage range and scheduled outage range are distinguished:
Carry out failure based on power failure data and planning data, scheduled outage range divides, and determine scope of power outage ratio
Matching rule, i.e. power failure message time of origin started in the single approval of plan and within the scope of the approval end times, and and scheduled outage
Commensurate in scope >=70%；Meanwhile it identifying and being determined as scope of power outage and scheduled outage range mismatch portion in scheduled outage message
Point, it distinguishes and is greater than scheduled outage range section and is less than scheduled outage range section；
S3, power-off event merge:
When handling multi-source data power-off event, multiple power failures influence distribution transforming is normalized, i.e., according to difference
Multiple outage informations are integrated together by ID, the power off time of the identical distribution transforming of data source in conjunction with verification power failure duration algorithm,
Guarantee only one power failure result set of same failure；
S4, data accuracy verification: it including wrong report data filtering, fails to report data amended record and reports data identification late；
(1) data filtering is reported by mistake
A, it for distribution transforming short time telegram in reply record, realizes and the shake for stopping telegram in reply record is filtered out；
B, being received based on every five minutes includes real-time section voltage, electric current, power data, continues 15 minutes checking prediction messages and stops
Electric range stops telegram in reply state, and identification state inconsistency record is to report record by mistake, adds Data Identification；
(2) data amended record is failed to report
A, it does not send a telegram in reply record for a long time for distribution transforming, realizes correctness verifying function, integrate 98 profile datas of history, school
Distribution transforming telegram in reply state correctness is tested, amended record distribution transforming is sent a telegram in reply the time；
B, comprehensive outage information data include, stop telegram in reply message not comprising record, are recognized as failing to report note to outage information
Record is recorded using outage information and carries out data supplement；
(3) data identification is reported late
Telegram in reply message time is stopped for access and differs 1 hour record with telegram in reply event time interval is stopped, is recognized as reporting note late
Report reason late is checked in record, analysis.
It in an embodiment of the present invention, can also be to power distribution network Dispatching Control System when handling multi-source data power-off event
The message of transmission keeps a record, including shake message, merging message information.
Compared to the prior art, the invention has the following advantages: the method for the present invention merges multi-source data, failure is added
Have a power failure and the technologies such as scheduled outage division, data accuracy verification, missing data amended record, improves power distribution network and stop data statistics of sending a telegram in reply
Accuracy, real-time and integrality.
