The core of the present invention is to provide falls bus disconnecting link method for detecting position and system during mother based on main station system heat,
Can whether close to put in place to bus disconnecting link during heat mother exactly and detect and alert, it is to avoid in power plant or transformer station
Owing to bus disconnecting link closes on-load broaching tool lock accident that is not in place and that cause, safety is high, highly reliable.
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
The a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under not making creative work premise, broadly falls into the scope of protection of the invention.
Embodiment one
The invention provides and fall bus disconnecting link method for detecting position during mother based on main station system heat, shown in Figure 1,
Fig. 1 falls the flow chart of the process of bus disconnecting link method for detecting position during mother for what the present invention provided based on main station system heat；
The method includes:
Step s101: receive the remote signalling displacement signal of a bus disconnecting link of power plant or transformer station's transmission；
It is understood that after the remote signalling receiving a bus disconnecting link conjugates signal, show now this bus disconnecting link
And a matched bus disconnecting link is closure state, so time this bus disconnecting link of receiving and matched
The remote signalling value of one bus disconnecting link is conjunction.
Step s102: whether determine the many groups heat prestored to fall during female equipment combines has the heat mother including bus disconnecting link
Equipment combines, if it has, the most female for the heat including bus disconnecting link equipment combination combined as Devices to test, and enters step
s103；Wherein, heat falls in female equipment combines to include two buses, two bus disconnecting links and bus connection switch；
Wherein, it is thus achieved that the method for the many groups heat prestored the most female equipment combination is: utilize electrical network in power plant or transformer station
The annexation of equipment, builds the topological diagram that is made up of " point ", " limit ", then this topological diagram obtained is carried out compartment analysis,
A series of topology such as the analysis of logic bus, electrical island analysis calculates, and analyzes the simulator group being capable of heat parent-operation
Close.
It is further known that, for a power plant or transformer station, obtaining much the most female equipment of group heat by above topology calculating
After combining and prestoring, if needing when following two situation occurs to prestore again through updating with upper topology calculating process
Many groups heat fall the combination of female equipment:
After situation one: when equipment is increased or decreased in power plant or transformer station, or change device location, many groups need to be recalculated
The most female equipment of heat combines and prestores；
Situation two: by the module being used for carrying out above topology calculating is configured so that it is power plant of periodically reruning
Or the most female equipment of the many groups heat in transformer station combines and prestores.Certainly, if periodically reruning can be by reality
Depending on the situation of border, the present invention is not construed as limiting, and the present invention does not the most limit the concrete numerical value in cycle carrying out reruning.
Step s103: judge respectively, in receiving the preset time period before the moment of remote signalling displacement signal, to obtain in advance
In the Devices to test combination taken, whether the active power parameter of each equipment is satisfied by preset requirement, if it is, enter step
s104；
It is understood that by above-mentioned judgement, be appreciated that the combination of this Devices to test is receiving remote signalling displacement signal
Moment before preset time period in the most normally work, if normally, just carry out subsequent operation, otherwise, if this Devices to test
Combination has occurred and that fault, then be made without follow-up judgement.
Wherein, the length of preset time period here can be according to practical situation sets itself.
Step s104: after certainly receiving the moment time delay Preset Time of remote signalling displacement signal, obtain respectively and judge to be measured
Equipment combines whether the active power balance amount of interior two buses is all higher than presetting balanced threshold, if it is not, then bus disconnecting link closes
Close not in place, and send the first warning signal and alert to warning system.
It is understood that active power balance amount refers to for a physics bus, by its connected whole
Switch flows into, flows out the algebraical sum of the active power of bus.Under normal circumstances, owing to falling in female operation in heat, can first close
Close the bus disconnecting link originally pulled open, then pull open another bus disconnecting link originally closed, therefore in the process, can have one
Section two bus disconnecting links of time are in closure state, and can be formed in addition to bus connection switch between double-bus under this kind of state
Another interim loop, bus connection switch can play shunting action by this interim loop, and part active power can be faced by this
Shi Huilu is done directly Power Exchange, and without bus connection switch, and this part active power cannot pass through original wattful power
Rate aequum relational expression calculates, if now calculate the active power balance amount of two buses further according to original relational expression if,
Unbalanced result, i.e. active power balance amount can be obtained saltus step can occur, be embodied in and be numerically the meritorious of two buses
Power-balance amount is more than presetting balanced threshold；Otherwise, if bus disconnecting link Guan Bi is not in place, then interim loop is not turned on, and reruns
The active power balance amount of two buses, the result still can being balanced, obtains after the most now receiving remote signalling displacement signal
The active power balance amount of two buses taken is less than presetting balanced threshold.
Wherein, default balanced threshold here could be arranged to zero, it is also possible to is disposed proximate to the value of zero.Preset Time can
To be set to 7s, the present invention does not limit the numerical value of default balanced threshold and Preset Time, and staff can be according to practical situation
Decide in its sole discretion.
It should be noted that and the present invention refers to electrically-based dispatching automation main station system based on main station system.
The invention provides and fall bus disconnecting link method for detecting position during mother based on main station system heat, the present invention is receiving
After the remote signalling displacement signal of a bus disconnecting link, however, it is determined that it is interior that this bus disconnecting link belongs to heat the most female equipment combination, first sentences
Break in receiving the preset time period before the moment of remote signalling displacement signal, each in this heat obtained in advance the most female equipment combination
Whether the active power parameter of individual equipment is satisfied by preset requirement, if it is, show that the female hot standby combination of this heat is before displacement
Normal work, after judging the displacement of bus disconnecting link afterwards this heat fall mother's equipment interior two buses of combination active power balance amount whether
It is respectively less than and presets balanced threshold；Due under normal circumstances, if the displacement of bus disconnecting link closes, the active power balance amount of two buses
More than presetting balanced threshold；If therefore the active power balance amount of two buses obtained after receiving remote signalling displacement signal is the least
In default balanced threshold, then show that bus disconnecting link Guan Bi is not in place, and then alert.As can be seen here, the present invention can be accurate
Whether bus disconnecting link during heat mother closed to put in place and detect and alert by ground, it is to avoid due to mother in power plant or transformer station
The on-load broaching tool lock accident that line disconnecting link Guan Bi is not in place and causes, safety is high, highly reliable.
Embodiment two
On the basis of embodiment one, present invention also offers and separately fall bus disconnecting link during mother based on main station system heat
Method for detecting position.
As preferably, step s103 specifically includes:
Step s301: judge, in receiving the preset time period before the moment of remote signalling displacement signal, to obtain in advance
In Devices to test combination, whether the active power of bus connection switch is less than presetting meritorious threshold value；If it does not, enter step s302；
If it is understood that in receiving the preset time period before the moment of remote signalling displacement signal, and obtaining in advance
The active power of the bus connection switch taken, less than presetting meritorious threshold value, shows itself not exist between double-bus the friendship of active power
Changing, in this case, after two bus disconnecting links all close, the active power balance amount of two buses also would not be jumped
Becoming, no matter i.e. whether bus disconnecting link closes and put in place, the active power balance amount of two buses is all consistently less than default balanced threshold.
As can be seen here, it is necessary to the active power at bus connection switch just can carry out follow-up judgement more than when presetting meritorious threshold value.
Wherein, meritorious threshold value of presetting here is 0 (or the value close to 0), and this is not construed as limiting by the present invention, staff
Can decide in its sole discretion according to practical situation.
Step s302: judge respectively, in receiving the preset time period before the moment of remote signalling displacement signal, to obtain in advance
The Devices to test taken combines whether the active power balance amount of interior two buses is respectively less than default balanced threshold, if it is, enter
Step s104.
It is understood that when bus disconnecting link conjugates, the active power balance amount of two buses is respectively less than pre-
If balanced threshold, if this aequum is excessive, then illustrate to exist for the measurement of current bus and institute's attached device thereof wrong or to be measured
Itself there is fault in equipment combination, so time can not carry out subsequent detection operation.
It addition, the order of step s301 and step s302 can be exchanged, first carry out the judgement of step s302, if judging
If result is "Yes", enter step s301；If if the judged result of step s301 is "Yes", enter step s104.Certainly,
The present invention does not limit the order between step s301 and step s302.
It is further known that, can gaining merit by two buses of the equipment combination the most female to each group of heat of predetermined period in the present invention
The active power of power-balance amount and bus connection switch obtains and stores, when receive remote signalling displacement signal after, from more than
Storage data in select receive remote signalling displacement signal moment before preset time period in obtain data carry out with
Upper judgement operation.Certainly, the present invention does not limit the frequency of predetermined period.
As preferably, also include after step s103:
After the moment time delay Preset Time receiving remote signalling displacement signal, obtain on the interior bus connection switch of Devices to test combination
The first current value；
Calculate the first current value to obtain in advance in the preset time period before receiving the moment of remote signalling displacement signal
Devices to test combination in the difference of the second current value of bus connection switch；
Judge the ratio of difference and the second current value whether less than presetting ratio, if it is, bus disconnecting link Guan Bi less than
Position, and send the second warning signal and alert to warning system.
It is understood that under normal circumstances, when all closing due to two bus disconnecting links, mother can be held by interim loop
Closing and produce shunting action, the current value on bus connection switch should saltus step downwards；Otherwise, if disconnecting link Guan Bi is not in place, then interim loop
Being not turned on, the current value of bus connection switch should keep constant compared with the current value received before remote signalling conjugates signal, or goes out
The most smoother existing variation, if after being embodied in and being numerically and receive remote signalling displacement signal, the current value of bus connection switch is jumped downwards
The amount (the i.e. first current value and the difference of the second current value) become and the ratio of the second current value less than default ratio, then show just
The operation median generatrix disconnecting link Guan Bi just completed is not in place.
Wherein, default ratio here can be decided in its sole discretion according to practical situation, and this deficiency is particularly limited to by the present invention.
It addition, the present invention does not limit the sequencing between above-mentioned steps and step s104.
As preferably, step s301 also includes:
If in receiving the preset time period before the moment of remote signalling displacement signal, the Devices to test combination obtained in advance
The active power of interior bus connection switch, less than presetting meritorious threshold value, sends the 3rd warning signal and alerts to warning system.
As preferably, step s302 also includes:
If in receiving the preset time period before the moment of remote signalling displacement signal, the Devices to test combination obtained in advance
The active power balance amount of interior two buses is not respectively less than and presets balanced threshold, sends the 4th warning signal and carries out to warning system
Alarm.
Wherein, after warning system receives warning signal, the group of one or more in following alarm operation can be used
Close: alarm operation includes will appear from showing on location of fault display screen in warning system；Or by warning system
Voice device carry out voice reminder or by corresponding warning information use note mode, warning system send to the people that works
On the mobile phone of member.Further, after receiving the first warning signal～the 4th warning signal, which warning system specifically uses
Planting or which plants alarm operation, the present invention is not defined.
Compared with embodiment one, the current value of bus connection switch is also judged by the present embodiment, owing to bus disconnecting link is sent out
Changing behind position, bus connection switch can be shunted by interim loop, makes the current value generation saltus step on bus connection switch, if receiving distant
Letter displacement signal after, the variable quantity of the current value of bus connection switch with receive remote signalling displacement signal moment before default time
Between in the Devices to test combination that obtains in advance in section the ratio of the second current value of bus connection switch less than presetting ratio, then show not
Form interim loop, i.e. bus disconnecting link Guan Bi is not in place, and carries out alarm operation, i.e. the present embodiment from power and electric current two side
Whether face is detected bus disconnecting link and is closed and put in place, improves accuracy and the reliability of detection；It addition, the present embodiment also add
To in receiving the preset time period before the moment of remote signalling displacement signal, the data of the Devices to test combination obtained in advance are entered
After row judges, if if judging to show to proceed detection, then carrying out alarm operation, prompting staff examines in time
