The core of the present invention is to provide one kind based on the hot female process median generatrix disconnecting link control method and device of main station system, Can be another bus disconnecting link corresponding to locking closure bus disconnecting link not in place when main website is remotely controlled operation, to the greatest extent may be used It is avoided that the phenomenon of on-load broaching tool lock occurs, it is highly reliable, it is safe.
To make the purpose, technical scheme and advantage of the embodiment of the present invention 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 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 the premise of creative work is not made, belongs to the scope of protection of the invention.
It is shown in Figure 1 the invention provides one kind based on the hot female process median generatrix disconnecting link control method of main station system, A kind of flow chart for process based on the hot female process median generatrix disconnecting link control method of main station system that Fig. 1 provides for the present invention; This method includes:
Step s11:The remote signalling of bus disconnecting link is disconnected displacement signal by receive power plant or transformer station's transmission one;
Step s12:The heat for determining to include bus disconnecting link is searched in falling female equipment combination from the multigroup heat prestored and falls mother Equipment is combined, and regard bus disconnecting link as current control disconnecting link;Wherein, heat to fall include in female equipment combination two buses, two Bus disconnecting link and bus connection switch;
Wherein, obtaining the multigroup heat prestored the method that female equipment is combined is:Utilize power network in power plant or transformer station The annexation of equipment, builds the topological diagram that be made up of " point ", " side ", then to obtain topological diagram progress compartment analysis, A series of topologys such as logic bus is analyzed, electrical island analysis are calculated, and the simulator group of hot parent-operation can be realized by analyzing Close.
It is further known that, for a power plant or transformer station, multigroup heat female equipment is obtained being calculated by above topology After combining and prestoring, if needing to prestore again through with the renewal of upper topology calculating process when there are following two situations Multigroup heat fall female equipment combination:
Situation one:When being increased or decreased in power plant or transformer station after equipment, or change device location, it need to recalculate multigroup Female equipment is combined and prestored heat;
Situation two:By to being configured for the module for carrying out above topology calculating, making its power plant of periodically reruning Or female equipment is combined and prestored multigroup heat in transformer station.Certainly, if carrying out periodic rerun can be by reality Depending on the situation of border, the present invention is not construed as limiting, and the present invention does not also limit the concrete numerical value in the cycle reruned.
Step s13:The status information of each bus disconnecting link of presetting database memory storage is retrieved, status information includes bus Whether in place whether disconnecting link close or disconnect, close information and displacement time;
Step s14:Determine to whether there is closure bus not in place in current hot female equipment combination according to status information Disconnecting link, if in the presence of locking currently controls the remote control break function of disconnecting link, if being not present, and the normal current control disconnecting link of control is carried out It is follow-up to disconnect control operation, and off-state and the time for currently controlling disconnecting link are recorded in presetting database.
It should be noted that being referred to based on main station system in the present invention is based on power dispatching automation main station system.
It is understood that remote signalling displacement signal (cut-off signal or closure signal) needs to carry corresponding bus knife The coding information of lock, confirms to need the bus disconnecting link of straighforward operation for searching, and receives after remote signalling displacement signal, in order to ensure letter Number accuracy, it is necessary to carry out anti-error verification to signal, examine whether remote signalling displacement signal is sent to corresponding website, reception is distant Whether the website of letter displacement signal returns to response, and whether the remote signalling displacement signal received is correct etc..
In addition, this method also includes:
Step s21:The remote signalling closure of bus disconnecting link is conjugated signal by receive power plant or transformer station's transmission one;
It is understood that after the remote signalling closure for receiving a bus disconnecting link conjugates signal, showing the now bus Disconnecting link and matched one bus disconnecting link is closure state, so when the bus disconnecting link that receives and with its The remote signalling value of bus disconnecting link is conjunction by one matched somebody with somebody.
Step s22:Searched in falling female equipment combination from the multigroup heat prestored and confirm to include remote signalling closure displacement signal The heat of corresponding bus disconnecting link falls the combination of female equipment, is combined as Devices to test;
Step s23:Judge respectively in the preset time period before at the time of receiving remote signalling closure displacement signal, in advance Whether the active power parameter of each equipment is satisfied by preset requirement in the Devices to test combination of acquisition;
It is understood that by above-mentioned judgement, can learn that Devices to test combination is receiving remote signalling closure displacement In preset time period before at the time of signal (become bit manipulation before) whether normal work, if normally, just progress subsequent operation, Otherwise, if Devices to test combination has occurred and that failure, need not subsequently it be judged.
Step s24:If meeting preset requirement, at the time of remote signalling closure displacement signal is received certainly after delay preset time, Obtain respectively and judge whether the active power balance amount of two buses in Devices to test combination is all higher than default balanced threshold, such as Really no, then the corresponding bus disconnecting link closure of remote signalling closure displacement signal is not in place;
It is understood that active power balance amount is referred to for a physics bus, the whole connected by it Switch is flowed into, the algebraical sum of the active power of outflow bus.Under normal circumstances, due to that in the operation that heat falls mother, can close first Pull open originally one is closed bus disconnecting link, then pulls open the another bus disconnecting link of script closure, therefore in the process, can there is one Section two bus disconnecting links of time are in closure state, and can be formed under this kind of state between double-bus in addition to bus connection switch Another interim loop, this interim loop can play shunting action to bus connection switch, 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 can not pass through original wattful power Rate aequum relational expression is calculated, if now further according to the active power balance amount of original relational expression two buses of calculating, Unbalanced result can be obtained, the as active power balance amount of two buses that embodies numerically is more than default balanced threshold; Conversely, if bus disconnecting link closure is not in place, interim loop is not turned on, the active power balance amount for two buses of reruning, according to The result that can be so balanced, i.e., now receive the active power balance amount of two buses obtained after remote signalling displacement signal No more than preset balanced threshold.
Wherein, default balanced threshold here is preferably arranged to zero, it can also be provided that close to zero value.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 actual conditions Decide in its sole discretion.
Step s25:The closure state of the corresponding bus disconnecting link of remote signalling closure displacement signal is recorded in presetting database, is closed Close whether in place information and displacement the time.
It is understood that due to including the female equipment combination of multigroup heat in main station system, accordingly, it is possible to different heat occur Female equipment combination receives remote signalling disconnection displacement signal simultaneously respectively and the situation of remote signalling closure displacement signal occurs, for same Two bus disconnecting links in the hot female equipment combination of group, general one, after bus disconnecting link closure, can just receive and disconnect another The signal of bus disconnecting link.
It should be noted that presetting database in each bus disconnecting link status information, can be after remote signalling control more After displacement newly store or artificial, by being manually entered what is be updated, presetting database improves process and bus The displacement mode of operation of disconnecting link is relevant, and the present invention is not especially limited, but is to ensure that every bus disconnecting link hair in main station system Change after bit manipulation, upgrade in time its status information.
It is further known that, step s23 process is specially:
Step s231:Judge in the preset time period before at the time of receiving remote signalling closure displacement signal, obtain in advance Whether the active power of bus connection switch, which is more than, in the Devices to test combination taken is preset active threshold value, if it is, mother before displacement Active power has value;
Step s232:Judge respectively in the preset time period before at the time of receiving remote signalling closure displacement signal, in advance Whether the active power balance amount of two buses is respectively less than default balanced threshold in the Devices to test combination first obtained, if it is, The active power balance of bus before then conjugating;
Step s233:If before displacement, mother active power has the active power balance of value and bus, then default want is met Ask.
It should be noted that step s231 and step s232 can be carried out side by side, it can also be determined as in step s231 In the case of "Yes", then step s232 is carried out, or in the case where step s232 is determined as "Yes", then carries out step s231, Which kind of specifically it is not especially limited using the mode present invention.
If it is understood that receive remote signalling displacement signal at the time of before preset time period in, with obtaining in advance The active power of the bus connection switch taken is not more than default active threshold value, itself active power is not present between showing double-bus Exchange, in this case, after two bus disconnecting links are closed, the active power balance amount of two buses would not also occur Saltus step, no matter that is, whether bus disconnecting link closes in place, the active power balance amount of two buses is consistently less than default balance threshold Value.As can be seen here, it is necessary to could subsequently be judged when the active power of bus connection switch is more than and presets active threshold value.Wherein, Here default active threshold value is preferably arranged to 0 (or close to 0 value), and this is not limited by the present invention, and staff can root Decided in its sole discretion according to actual conditions.
In addition, when bus disconnecting link is not conjugated, the active power balance amount of two buses needs to keep balance, i.e., near Like being 0, if aequum is more than default balanced threshold, illustrate to exist for the measurement of current bus and its institute's attached device it is wrong or There is failure in itself in Devices to test combination, so when can not carry out subsequent detection operation.
It is further known that, can be by predetermined period to the active of each group heat two buses that female equipment is combined in the present invention Power-balance amount and the active power of bus connection switch are obtained and stored, after remote signalling displacement signal is received, from the above Select in the preset time period before at the time of receiving remote signalling displacement signal the data that obtain to carry out in the data of storage with It is upper to judge operation.Certainly, the present invention does not limit the frequency of predetermined period.
Preferably, after step s23, this method also includes:
Step s31:From after delay preset time at the time of receiving remote signalling closure displacement signal, Devices to test combination is obtained Current value after displacement on interior bus connection switch;
Step s32:Out of default parameter database, obtain the remote signalling closure that receives certainly prestored and conjugate signal Current value before the displacement of the interior bus connection switch of Devices to test combination in preset time period before moment;
Step s33:If current value is more than current value after displacement before displacement, current value and electric current after displacement before displacement are calculated The difference of value and the ratio of current value before displacement;
Step s34:Judge whether difference is less than default ratio, if it is, the corresponding bus of remote signalling closure displacement signal Disconnecting link closure is not in place.
It is understood that under normal circumstances, when all being closed due to two bus disconnecting links, interim loop can be held mother Close the current value and active power amplitude produced on shunting action, bus connection switch and answer downward saltus step;If conversely, disconnecting link closure less than Position, then interim loop is not turned on, the current value or active power amplitude of bus connection switch and receive remote signalling displacement signal before Current value (or active power amplitude) compared to should keep constant, or there is smoother variation, be numerically if embodying Receive after remote signalling displacement signal, amount and the electric current before displacement of current value (or the active power amplitude) saltus step downwards of bus connection switch The ratio for being worth (or active power amplitude) is less than default ratio, then show the operation median generatrix disconnecting link closure that has just completed less than Position.
Wherein, default ratio here can be decided in its sole discretion according to actual conditions, and the present invention is particularly limited to this deficiency.
In addition, judged in above example according to current value, also can be according to active power in other embodiment Amplitude is judged, is specifically not especially limited using which kind of mode present invention.
It should be noted that during judging whether bus disconnecting link closes in place, as long as two buses after its displacement Active power balance amount be not all higher than default balanced threshold, or current value (active power amplitude) saltus step ratio be less than it is pre- If ratio, arbitrarily there is one kind in both of these case, then shows that bus disconnecting link closure is not in place.
Preferably, also include when in hot female equipment combination in the presence of closure bus disconnecting link not in place:
Locking alarm signal to warning system is sent to be alerted.
Wherein, when carrying out locking, staff finally learns not in place in the presence of closure in hot female equipment combination in time Situation, be easy to staff to be handled in time.
In addition, warning system is received after alarm signal, one or more of groups in following alarm operation can be used Close:Alarm operation is shown including will appear from location of fault on the display screen in warning system;Or by warning system Voice device carry out voice reminder or by corresponding warning information using short message by the way of, by warning system send to work people On the mobile phone of member.Further, after the first alarm signal~four alarm signal is received, which warning system specifically uses Plant or which plants alarm operation, the present invention is not defined.
Main station system heat female process median generatrix disconnecting link control method is based on the invention provides one kind, is recorded in real time each The status information of individual bus disconnecting link, whether status information close or disconnect including bus disconnecting link, close whether in place information and The displacement time;After the remote signalling for receiving bus disconnecting link disconnects displacement signal, pass through the state of contact pin presetting database memory storage Information, it is determined that with the bus disconnecting link belong to that same heat falls that female equipment combines it is another whether bus disconnecting link is closed it is not in place, if It is, then the remote control break function of the locking bus disconnecting link, if it is not, controlling the bus disconnecting link normally to disconnect.It can be seen that, this method can When main website is remotely controlled operation, before remote control disconnects bus disconnecting link, the closure state of another bus disconnecting link, one are confirmed in time There is closure situation not in place in denier, then its break function of timely locking, so that the phenomenon for having prevented on-load broaching tool lock substantially goes out It is existing, it is highly reliable, it is safe.
Present invention also offers one kind based on the hot female process median generatrix disconnecting link control device of main station system, referring to Fig. 2 institutes Show, a kind of structural representation based on the hot female process median generatrix disconnecting link control device of main station system that Fig. 2 provides for the present invention.
