In embodiments of the present invention, the present invention is to increase a kind of switch non-three phase separating brake in electric power scheduling automatization system
Judgment method, borrow rule judgement and establish the reasoning from logic of computer, and will finally sentence intelligent decision result and be generated as image
Intuitive switch non-three phase separating brake bulletin carries out alarm display.
The S10: data source, the auxiliary related fortune for judging to need to obtain each application system of power grid of switch non-three phase separating brake are obtained
Data source of the row data as switch non-three phase separating brake judgement comprising the quartile or the displacement information of coincidence, switch of switch are distant
Operation information, real-time telemetry data etc. are controlled, the present invention passes through preprocessing process: electric power scheduling automatization system monitors switch in real time
Information is conjugated, program is established individually switch non-three phase separating brake auxiliary judgment thread and monitored, executes one within timer 5 seconds
It is secondary, scan the 10KV switchgear state of the whole network.
The S20: if the displacement information for receiving switchgear is quartile, the first judgement of starting, first is judged as this
It is secondary switch quartile operation whether be dispatching automation main website remote control operation, then terminate to judge if it is remote control operation, if non-
Remote control operation, opens the S30, then the separating brake for recording current switch device type and opening time as current switch equipment is believed
Breath, and be deposited into switch separating brake queue.
After the S30, before the S40 further include: S60, S60 are the selecting steps of object before intelligent decision, are opened
Closing non-three phase separating brake judges thread according to pretreated as a result, acquisition carries out intelligence to the switchgear type of triggering judgement respectively
It can judgement.Switchgear is divided into different type by electric power scheduling automatization system, such as sets the switch that operation of power networks monitors in real time
Back-up is capacitor switch, on-load switch, line switching, transformer side switch, bus connection switch etc..Switch non-three phase separating brake is sentenced
It is disconnected, it needs the switch to the whole network 10KV above to distinguish, is generally divided into capacitor switch and non-electrical container valve
Two major classes.
The S40: if the opening time of the current switch equipment in the real-time telemetry data of current switch equipment continue to
When pre-established threshold, the second judgement is opened, second is judged as the intelligent decision of switch non-three phase separating brake, the intelligent decision, with electricity
For container valve, capacitor switch obtains each phase real-time current value in this interval after switch quartile continues two minutes, if
There is a phase current absolute value to be greater than 20 (setting 50 originally) A, then the reasoning results are this switch non-three phase separating brake, and it is non-to generate switch
Full phase separating brake bulletin.Intelligent decision foundation: when the full phase separating brake of switchgear, theoretically the current value of each phase of switchgear is 0,
If non-three phase separating brake, at least phase switch is "on" position, then the current value of this phase of "on" position is necessarily greater than
0, in the ideal situation, it is assumed that theoretical current value 0 is used as decision condition, it is contemplated that in actual dispatching automation
System data acquisition process will appear the disturbing factors such as error, drift, can go out if using theoretical current value 0 as decision condition
Now judge by accident, it is contemplated that the influence of above-mentioned disturbing factor, electric power scheduling automatization system Telemetry Data Acquisition allowable error ± 3%,
By taking the electric system of Chaozhou power supply bureau as an example, the maximum capacitor 9.75Mvar of Chaozhou power supply bureau electric system at present, corresponding mutually electricity
532A, the smallest capacitor 0.45Mvar, corresponding phase current 25A are flowed, is calculated by 3%, maximum error is about 16A, so setting
Determine 20A to be empirically worth, does not influence the non-three phase separating brake judgement of minimum capacity again under the influence of avoiding disturbing factor, guarantee final
The accuracy rate of judging result.By taking non-electrical container valve as an example, non-electrical container valve after switch quartile continues two minutes, work as by acquisition
Preceding switch three-phase real-time current value, if there is three-phase current absolute value and be greater than 10A, then the reasoning results be this switch non-three phase
Separating brake, and generate switch non-three phase separating brake bulletin.The judgement of capacitor switch non-three phase and the judgement of non-electrical container valve non-three phase
Difference is that electric current is electric current when non-electrical container valve (such as line switching) closes a floodgate at full capacity when capacitor switch closes a floodgate
Amplitude is 0 at full capacity, so going judge to switch whether the threshold value of non-three phase is had any different by phase current.Non-electrical container valve
Using three-phase current absolute value and be greater than 10A as Rule of judgment, this 10A is similarly an empirical value, similarly, it is contemplated that electric
Power dispatch automated system data acquisition will appear error, the factor of drift, and the also free induced voltage for filling route causes
The disturbing factors such as induced current, such as the route where switch be it is unloaded, when sky fills route, can switch is non-three phase
Because of the too small judgement that pre-established threshold is not achieved and misses non-three phase of electric current.It is that the pre-established threshold is with needing to add explanation
Current switch equipment conjugates the lasting critical period of information, and in embodiment, for two minutes, this can also be managed for two minutes
Solution is empirical value, it is not limited here.
The S50 provides the step of a variety of alarm modes show the reasoning results for switch non-three phase separating brake auxiliary judgment, accuses
Police's formula relies on original dispatch automated system alarm function, i.e., in the place display such as alarm window；Either, it is sent to scheduling
The recording playing system phonic warning etc. of member's work station.Outdoor scene operation has and is not limited to following several:
A) window is alerted on warning information；
B) newest warning information presenting bank；
C) sound equipment, voice prompting；
D) automatic/hand pushes away figure, i.e., releases or manually have access to failure plant stand main wiring diagram automatically；
E) figure discoloration or flashing；
F) it is prompted by mobile phone short message；
G) acknowledged alarm.
Switch the alarm format of non-three phase separating brake bulletin: " station XX XX switchs non-three phase separating brake ".
It further include that S70 and S80 check that this sets if the displacement information for receiving switchgear is coincidence after the S10
It is standby to whether there is in switch separating brake queue, if it is present deleting the facility information in switch separating brake queue, terminate to sentence
It is disconnected.
The present invention is applied to dispatching automation of electric power systems main website, can be to power train when open-phase operation occurs for switch
System operation generates very big harmfulness.Switch open-phase operation can make power grid generate negative phase-sequence and zero-sequence current (voltage), make power grid
Hair, it is defeated, match, electrical equipment is damaged, and not only causes economic loss to client and society, also relate to safety problem, disconnected
