The present invention carry out based on the area power grid outage information of grid power blackout characteristic study and judge process mainly comprise fault trip with operation have a power failure differentiate, telesignalling dithering filters, dispatching maintenance ticket mates three links.
As shown in Figure 3, the present invention's criterion of carrying out line fault tripping operation is for having switch changed position (by be incorporated into point) signal, total (or interval the is total or protection act) signal of accident and electric current before switch changed position is greater than 5 amperes.Introduce remote measurement amount as trip criteria, on the one hand can by actual for a part to have a power failure for operation or had a power failure to reject from tripping operation information at the circuit carrying out signal debugging, mean that the tripping operation of charging extension wire will not include system statistics on the other hand.In actual applications; when monitoring a certain switch changed position (by be incorporated into point) signal; namely the accident whether having respective switch before and after switch changed position in 60 seconds total (or interval is total or protection act) signal is checked; if have, check whether the switch changed position electric current of first 1 second is greater than 5 amperes further; if three conditions are all satisfied, be then judged to primary fault tripping operation.
The criterion that line loop operation has a power failure, for only there being switch changed position (by be incorporated into point) signal, does not have accident total (or interval always or protection act) signal.In actual applications; when monitoring a certain switch changed position (by be incorporated into point) signal; namely check the accident whether having respective switch before and after switch changed position in 60 seconds total (or interval is total or protection act) signal, if not, be judged to operation and have a power failure.
There is work value according to switch changed position (by be incorporated into point) front 1 second flow through switch, add up the load loss that this line outage causes, put aside the situation of load prepared auto restart.
For 10kV circuit, system only pays close attention to the relevant information of transformer station's outlet switch (main line switch), and main line switch has a power failure and namely thinks line outage; For 35kV and 110kV circuit, system only pays close attention to the relevant information of source-side switches, and power supply slowdown monitoring switch has a power failure and namely thinks line outage.
Every 5 minutes of line outage judge module generates a file, and this file was named according to the generation moment, content be generate 10kV main line that in first 5 minutes of moment, this area occurs, the tripping operation of 35kV and 110kV line fault, operation have a power failure and the information such as load loss.Data platform file reception and memory module calling in every 5 minutes once comprise the file of outage information, in order to prevent loss of data, data platform file reception and memory module call 6 files in first 30 minutes at every turn, if call successfully, then by file warehousing, for successful file of putting in storage, do not cover in calling below, for the file of unsuccessful warehouse-in, in time calling of 5 below, still likely successfully put in storage.
There is the problem that remote signals is frequently shaken in some transformer station, the RTU of some transformer station is not bery stable, occurs the situation that batch remote signalling conjugates simultaneously, and also carry out signal debugging during some line outage and upload a large amount of signal, these situations all can cause misreport of system.It is after analysing in depth various wrong report information that outage information optimizes module, according to the feature that fault trip and operation have a power failure, by the logical relation of switch changed position time, the situation of dispatching maintenance ticket is submitted in conjunction with relevant unit, formulate series of optimum filtering rule, the judged result of line outage judge module is optimized, a large amount of invalid signals is filtered, effectively improves rate of accurateness.
If one the circuit information number that tripped in a day is more than or equal to 3, then think caused by signal jitter, system will filter out all tripping operation information of this circuit; If at synchronization, certain transformer station occurs that many line switchings close displacement (being more than or equal to 3) by assigning to, then think that this station RTU is restarted the signal caused and resetted, system will filter out corresponding outage information; If one operate power cut record, its switch separating brake and closing time interval are less than or equal to 30 minutes, and system will filter out this outage information; If one circuit had many to operate the record had a power failure in one day, then system is merged into a new record, and the opening time of new record is the opening time of Article 1 record, and the closing time of new record is the closing time of the last item record.
As shown in Figure 4; accuracy rate is studied and judged in order to improve further; identify and be mistaken for fault trip because sending out the total or protection act signal of accident by mistake and be actually the information that operation has a power failure; reject the false outage information that interruption maintenance circuit carries out signal debugging generation, outage information is mated with dispatching maintenance ticket by outage information optimization module.For an outage information, system is mated in the dispatching maintenance ticket submitted in relevant unit according to the title of power failure equipments, if the match is successful, then the type according to dispatching maintenance ticket after corresponding outage information stamps " meter stops " or " non-meter stops " label.Mend for relevant unit after preventing line tripping and propose maintenance application, require that switch opening time is later than application submission time, and be no more than 1 hour on-stream time early than application.Tripping operation information with " meter stops " or " non-meter stops " label belongs to the operation by mistake sending out accident total (interval total, protection act) signal more and has a power failure, and system will move on to operation power failure list from tripping operation list this type of information; The how true genus operation of operation outage information with " meter stops " or " non-meter stops " label has a power failure.
For an outage information, system is mated in the dispatching maintenance ticket submitted in relevant unit according to the title of power failure equipments, if the match is successful and switch opening time is later than dispatching maintenance ticket on-stream time, and early than dispatching maintenance ticket time of completion, then think that this outage information is carried out signal debugging and caused between circuit turn(a)round, filtered.
By the area power grid outage information analysis method based on grid power blackout characteristic provided by the invention, economize and adjust side can grasp the whole province's each department electric network fault tripping operation and operation outage information comprehensively, significantly improve the accuracy of fault trip and operation outage information.
