Detection method and system.
Background technology
Generally by detection of excessive current phenomenon, distribution line monitor terminal (FTU) judges whether circuit breaks down.
From from the aspect of simple, economic dispatch, one group of protective current transformer (TA) is only installed in on-pole switch, ring main unit generally, and
It is not as in wire-outgoing breaker while installing one group of protection TA and one group of measurement TA.Although can so meet detecting
The requirement of electric current, but due to protecting TA dynamic ranges excessive, bring the not high problem of current measurement precision.Particularly circuit is born
When lotus is lighter, often there is the situation of measurement currents around zero, so that the change of load current effectively can not be monitored
Change.
Basic link and equipment of the distribution terminal as power distribution automation, bear the monitoring sum for realizing Distribution Network Equipment
According to collection, remote measurement, remote signalling, remote control, fault current test, relay protection, communication forwarding and the diagnosis of failure, isolation, position and
The functions such as recovery, its running status will be directly affected and reflect distribution automation system.
The content of the invention
It is an object of the invention to provide a kind of distribution automation terminal signal detecting method and system, by using it is many when
Between section carry out the collection of data, improve current measurement precision；Solve existing distribution automation terminal signal detection precision low
Problem.
To solve above-mentioned technical problem, the present invention is achieved by the following technical solutions：
The present invention is a kind of distribution automation terminal signal detecting method, is comprised the steps：
Step one, data acquisition：Multiple ammeters are gathered simultaneously at electricity consumption scene, gather once at interval of time t, including sky
Not busy collection and normal acquisition；
Step 2, parameter refresh：Whether Detection task parameter occurs changing with ammeter parameter first, if there is change,
Corresponding task list and ammeter list are updated, while to being modified to corresponding flag bit with its list row；
Step 3, idle collection：
A. check whether wait task occur, if there is, then exit epicycle collection；
B. the ammeter data amount collection informosome of highest priority is obtained, and information is gathered as current ammeter data amount
Body；
If C. current ammeter data amount informosome be space-time, exit epicycle collection；
D. current ammeter data amount collection informosome is acquired；
Step 4, normal acquisition：
S1 extract in the Lists task list of normal acquisition wait task list, while by wait task collection information
Body is initialized；
S2 will wait task list to remove from completed list；
The task of completed principal and subordinate's normal acquisition is removed from current list by S3, again blunt to appoint to this round is new
Business list；
If S4 new round Lists task is sky, normal gatherer process is now exited, then carries out idle collection；
S5 travels through current task acquisition list, gathers informosome with the ammeter data for obtaining highest priority；
Step 5, the collection measure dot number evidence obtained by step 3 and step 4 are carried out contrast with communication protocol and are examined
Survey.
Further, the idle collection is started in no normal acquisition task, in normal acquisition task, idle
Collection must immediately exit from performing normal acquisition；The normal acquisition, refers to and is triggered according to the collection clock setting of system task
Collection.
A kind of system of distribution automation terminal signal detection, it is characterised in that including collection measure dot number evidence, communication rule
About and control flow；The communication protocol is arranged by main website, curve index is connected to control flow；The collection measure dot number
Output signal is detected according to by control flow；The detection output signal includes display information output, information output and alarm/jump
Lock is exported.
The invention has the advantages that：
The present invention's has detected value accurately for distribution automation terminal signal detecting mode, is easy to control, using many
Time period carries out the collection of data, improves current measurement precision；By the system and method can realize the communication to distribution terminal,
Function and performance etc. carry out comprehensive, efficient test, to ensure the stable of terminal, reliability service.
Certainly, the arbitrary product for implementing the present invention is it is not absolutely required to while reaching all the above advantage.
