Brief description of the drawings
Fig. 1 is a kind of method flow diagram for judging scheduling system busbar power-off telegram in reply in time proposed by the present invention.
Embodiment
Reference picture 1, a kind of method for judging scheduling system busbar power-off telegram in reply in time proposed by the present invention, its feature exist
In comprising the following steps：
The first step, predetermined voltage threshold and the wandering section of voltage.
Voltage threshold can as the criterion of the three-phase voltage sum of target bus, specifically can section [40kV,
60kV] on value.Described three-phase voltage sum is the total value of three-phase voltage sum in the present invention.In addition, because bus powers off
Afterwards, may be wandering phenomenon with the magnitude of voltage of very little on bus, so judging whether magnitude of voltage is zero, actually judgement is
It is no it is positive and negative it is wandering value section in.In present embodiment, the wandering section of voltage can be used as judging voltage whether the standard for being zero,
For example, working as the wandering section value [- 1kV, 1kV] of voltage, then when magnitude of voltage is interior at [- 1kV, 1kV], voltage is all considered as zero.Tool
Body, when the value in the wandering section of voltage can determine according to actual conditions, such as value [- a, a], a can appoint in 0≤a≤1kV
Meaning value, but a had better not be more than 1kV, in order to avoid judge by accident.
The remote signalling value of second step, breaker on real-time monitoring objective bus, and judge remote signalling value saltus step information.
Remote signalling value is possible with two kinds of saltus steps, i.e. target bus shutdown transient, and remote signalling value should be low from high level saltus step
Level；Target bus is sent a telegram in reply moment, and remote signalling value should be high level from low transition.So when detecting remote signalling value saltus step,
Can determine whether first remote signalling value whether from high level saltus step be low level, if it is, determining whether target bus three-phase voltage
Sum changes；If it is not, then judge remote signalling value whether from low transition for high level, if it is, determining whether target
Bus three-phase voltage sum changes；If it is not, then monitor again and judge remote signalling value saltus step information.
When it is implemented, when detecting remote signalling value saltus step, it can also first determine whether remote signalling value is high from low transition
Level, if it is, determining whether that target bus three-phase voltage sum changes；If it is not, then judge remote signalling value whether from height
Level saltus step is low level, if it is, determining whether that target bus three-phase voltage sum changes；If it is not, then supervise again
Survey and judge remote signalling value saltus step information.
3rd step, according to remote signalling value saltus step information judged result, by target bus three-phase voltage sum before remote signalling value saltus step
Contrasted respectively with voltage threshold and the wandering section of voltage with target bus three-phase voltage sum after remote signalling value saltus step, and according to contrast
As a result, bus power-off or telegram in reply state are judged.
In the case of target bus is powered off or sent a telegram in reply, not only breaker remote signalling value changes, under normal circumstances, target bus
On magnitude of voltage before and after remote signalling value saltus step also should it is corresponding with remote signalling value saltus step generation change.For example, when target bus breaks
Electricity, i.e. target bus are changed into power failure state from electricity condition is obtained, and now, remote signalling value is low level from high level saltus step, and remote signalling value is jumped
Target bus three-phase voltage sum should be greater than voltage threshold before change, and target bus three-phase voltage sum should be after remote signalling value saltus step
Zero, i.e., in the wandering section of voltage.When target bus is sent a telegram in reply, i.e., target bus is changed into obtaining electricity condition from power failure state, now,
Remote signalling value is high level from low transition, and target bus three-phase voltage sum should be located at the wandering area of voltage before remote signalling value saltus step
In, target bus three-phase voltage sum should be greater than voltage threshold after remote signalling value saltus step.
So the 3rd step of this method for judging scheduling system busbar power-off telegram in reply in time may be accomplished by.
When remote signalling value from high level saltus step is low level, then judge whether to meet simultaneously target bus three before remote signalling value saltus step
Phase voltage sum is more than voltage threshold, and target bus three-phase voltage sum is located in the wandering section of voltage after remote signalling value saltus step,
If it is, judge bus power-off；If it is not, then monitor again and judge remote signalling value saltus step information；When remote signalling value is jumped from low level
It is changed into high level, then judges whether that target bus three-phase voltage sum is located at the wandering section of voltage before meeting remote signalling value saltus step simultaneously
It is interior, and target bus three-phase voltage sum is more than voltage threshold after remote signalling value saltus step, if it is, judging bus telegram in reply；If not,
Then monitor again and judge remote signalling value saltus step information.
Specifically, when remote signalling value from high level saltus step is low level, target bus three-phase before remote signalling value saltus step is first determined whether
Whether voltage sum is more than voltage threshold, if it is not, then monitoring again and judging remote signalling value saltus step information；If it is, continue
Whether target bus three-phase voltage sum is in the wandering section of voltage after judging remote signalling value saltus step, if it is not, then monitoring again
And judge remote signalling value saltus step information；If it is, judge bus power-off.
When remote signalling value from low transition is high level, target bus three-phase voltage sum before remote signalling value saltus step is first determined whether
Whether in the wandering section of voltage, if it is not, then monitoring again and judging remote signalling value saltus step information；If it is, judge distant
Whether target bus three-phase voltage sum is more than voltage threshold after letter value saltus step, if it is not, then monitoring again and judging remote signalling value
Saltus step information；If it is, judge bus telegram in reply.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
