Embodiment one
A kind of intelligence for fault wave recording device and traveling wave ranging device disclosed in one or more embodiments
Interlock method, comprising:
Fault wave recording device or traveling wave ranging device or failure wave-recording and travelling wave ranging in substation are integrally disguised
In setting, after a certain device trigger recording, linkage data packet is generated, and the linkage data packet is sent by the data-interface that links
To next device；The linkage data packet includes at least device type and starting type information；
Next device determines whether to trigger according to the device type in linkage data packet with starting type information
The linkage of the machine；Meanwhile linkage data packet is transmitted to another device by the data-interface that links.
Referring to Fig. 2, next device is sentenced according to the linkage data packet extract equipment type and starting type information that receive
Whether the starting type of breaking is failure, if so, the trigger recording of triggering the machine, the i.e. linkage of triggering the machine；Otherwise, motionless
Make.
Device described above refers to fault wave recording device or traveling wave ranging device or failure wave-recording and travelling wave ranging
One of integrated apparatus is also the same below.
After device normal boot-strap, electric system electrical quantity signal is acquired, if electric system is broken down, various electrical quantity letters
The variation such as number can mutate, is out-of-limit, and device can recording starting, i.e. trigger recording at this time.
Referring to Fig. 2, after first device starting, linkage data are sent to second device by linkage data transmission interface
Packet, after second device receives the linkage data packet of first device transmission, therefrom extract equipment type and starting type are believed
Breath, and linkage data packet is forwarded to third device by linkage data transmission interface；And so on, data forwarding can be passed through
Form set up ring topology network more flexiblely in substation.In Fig. 2, each device is provided with two and receives interface R1
And R2, two transmission interfaces T1 and T2.
Linkage data transmission interface and linkage data receiver interface are both designed as optical fiber interface, such as ST mouthfuls；Pass through linkage
Data-interface realizes the indirect forwarding of linkage data packet, enable to be routed it is simpler flexibly, and without designing too many number
According to interface.
It should be noted that linkage data transmission interface and linkage data receiver interface are arranged on device, therefore, need
Guarantee that there is linkage data transmission interface and linkage data receiver interface on device, or original linkage interface be transformed,
Achieve the function of linkage data receiver and transmission.Setting has the interface of linkage data receiver and sending function on device
It is that those skilled in the art can be realized according to the prior art, therefore, setting or forms of modification for interface are not done in detail
It states.
The data packet frame format that links is as shown in the table.
Table 1
Wherein, device type definition is as follows:
Table 2
It is as follows to start type definition:
Table 3
It is counted according to device field operational data, " traveling wave ranging device ", which is more susceptible to the influence of route high frequency spurs, to be caused accidentally to open
It is dynamic；And " fault wave recording device " is influenced due to not acquiring high-frequency signal not vulnerable to high frequency spurs, is started more reliable.
When electric system is broken down, it is provided simultaneously with multinomial feature, for example occurs that voltage jump, electric current are out-of-limit, open simultaneously
Pass amount movement etc., by extract linkage data packet in device type information and starting type information can distinguish be failure also
It is disturbance, and then determines whether to trigger the machine linkage.
Such as: certain transmission line of electricity occur ground fault, cause busbar voltage reduce more lower limit, line current increase on
It limits, voltage, current break is existed simultaneously in failure process, when failure occurs, detect that protective relaying device switching value acts；This
When may determine that as failure；If load variations occur for transmission line of electricity, causes line current to mutate, other do not occur such as voltage
The movement of protective relaying device switching value does not occur, is judged as disturbance at this time for out-of-limit, mutation.
Power equipment manufacturer can also be according to " the starting device type " that linkage data packet is judged, " starting type ", knot
It closes equipment feature and live operation characteristic is formulated, adjustment, linkage starting logic is arranged, reach differentiation disturbance and failure, effectively keep away
Exempt from whole station malfunction, the purpose of error starting that improves existing traveling wave ranging device vulnerable to noise jamming influence.
