Description of drawings
Fig. 1 is the structure principle chart of realizing the system that transformer station's wrong report remote signalling dispatching terminal filters of the present invention.
Embodiment
As shown in Figure 1, the system that realizes that transformer station's wrong report remote signalling dispatching terminal filters of the present invention, the remote signals processing server that is based on the platform independent on the network that is increased to the SCADA dispatching system is set.
This server design adopts and the SCADA dispatching integrated design technology, can share figure, history library, storehouse, device parameter, the network service etc. in real time of SCADA.Can directly visit the various resources of SCADA by the interface native system of standard.System can be joined seamlessly to operation in the SCADA net, has special thread to catch the switch actuating signals of SCADA system and gear signal etc. in real time, and when capturing new remote signalling displacement, the beginning call signal is analyzed thread signal is analyzed.Differentiate echo signal by the signal processing rule of design and belong to normal remote signals or mistake remote signals.The remote signalling analysis result shows by man-machine interface, and provides signal to confirm and functions such as automatic deposit and inquiry.
System of the present invention specifically is provided with data analysis center, control data corporation and the data monitoring center by modularized design, contacts the nucleus module of each module with data analysis center as it.Each module has the entrance and exit of standard, makes things convenient for exchanges data between exchanges data and following possible application.
Described data monitoring center, platform by the standard interface accessing SCADA system that arranges, and then obtain required following data: a class is that the electrical network static information refers to that mainly the annexation between the electrical network primary equipment is topological relation information, these static informations can obtain by the artwork integrated technique of SCADA system, load automatically when program start.Another kind of is that electrical network dynamic operation information is real-time remote measure and communication data, automatically obtain by the data flow mode, instantaneous renewal, namely the present invention can instantaneously capture and start corresponding handling procedure when the real-time telemetry remote signalling data of SCADA system change.
Consider present situation and the on-the-spot actual demand of SCADA system, only the switch changed position signal of SCADA is analyzed among the present invention, still reserved the analysis interface of guard signal and disconnecting link signal, can insert immediately when needed.Therefore, need data monitoring of the present invention center that the switch changed position signal is separated from all remote signalling data; Described data monitoring center is with switch, disconnecting link signal, gear information, and remaining auxiliary remote measure and communication data with information such as power system operating mode, equipment states, are sent to data analysis center respectively.
Described data analysis center when capturing new remote signalling displacement, just begins call signal analysis thread signal is analyzed.The analysis of switch remote signals is a comprehensive process, relate to search and the analysis of power network topology relation, analysis and judgement, the equipment of equipment state, factory station or equipment operational mode moves in rational judgement, the SCADA system to the Signal Processing mode, once with the matching relationship of secondary device etc.Emphasis wherein is the Partial Feature of the normal running of electrical network primary equipment, accident condition, abnormality and false positive signal.
Data analysis center is to the analyzing and processing of signal among the present invention, specific design has special signal processing rule storehouse, signal to be analyzed is the entry condition of rule base, and relevant remote signalling telemetry intelligence (TELINT) is come the picked up signal analysis result as the subsidiary conditions of rule judgment by the coupling of rule.
Normal signal described in the present invention comprises the various remote measure and communication signals that electrical network sends under normal condition, the unusual and fault-signal that electrical network sends under improper and malfunction, and the test signal that under debugging or inspecting state, generates of equipment etc.
When setting normal signal regular among the present invention, need consider repair apparatus; Charging equipment not; YX period go beyond the scope (determining whether to adopt according to field condition); Receive the switchgear of remote control (comprising remote control execution and the success of anti-school) item in advance; Switch changed position and switch failure tripping operation/SOE item exist simultaneously; Switch and protection actuating signal exist simultaneously; The YC=0 of switch separating brake corresponding device; The YC of switch combined floodgate corresponding device〉0; Satisfy self-defined normal remote signalling condition; The situation of normal signal (at gear signal).
1) repair apparatus is the class special installation in the electrical network, and it has following characteristics: (1), each side of equipment is not connected state, and namely each the side point from equipment all can not find power supply point; (2), equipment has the ground connection disconnecting link or earth connection is ground state; (3) may have distinctive mark boards such as ground connection, maintenance or ad hoc inspection and repair on the equipment.In the native system repair apparatus there is special regulatory requirement, this is because repair apparatus may frequently or occasionally send some abnormal operation signals because of the debugging requirements of one's work, these signals are signals of the actual generation of slave station end, though be not false positive signal, if but can not correctly identify then may cause interference to dispatcher's work, so require correct identification to have the equipment of maintenance attribute in this application, the various signals that this kind equipment produces made identification.Obtain the sign board type of equipment among the present invention by the real-time storehouse of SCADA system, all regard all equipment with maintenance, ground connection, ad hoc inspection and repair attribute wherein as repair apparatus, the signal of its generation is attributed to normal signal.Current all repair apparatus can show by man-machine interface.
2) not charging equipment refer to equipment each side tool lock all at open position, be in the not equipment of electriferous state, its signal that produces is the same with repair apparatus, may be debug signal.Not charging equipment judge one is whether the disconnecting link of seeing each side of equipment is in the separating brake position, the 2nd, see from each side of equipment to search power supply point the system.If these two are all satisfied, then equipment is considered to not charging equipment.The judgement of charging equipment will not realize by perfect topological analysis program.
3) switch trip and switch failure tripping operation/switch S OE exist simultaneously; If switch trip and two items of this switch failure tripping operation all exist simultaneously, illustrate that switch is emergency stop valve trip.This rule designs at the common technique of SCADA system.The SOE(sequence of events recording), exactly when remote terminal unit detects the displacement of remote signalling state, the moment, displacement state and the equipment serial number of record remote signalling displacement are formed logout information and are transmitted to main website.As long as alarm shows SOE, illustrate that remote terminal unit at least receives the remote signalling contact action message of a reality.If therefore two items of switch trip and this switch S OE all exist simultaneously, illustrate that RTU is the remote signalling displacement signal of having received switch really.And if the switch tripping operation that has an accident then can produce two items of switch separating brake item and switch failure tripping operation item, this also can be used as the basis for estimation of normal remote signalling.
4) receive the switch of remote control item in advance; If switch is carried out the remote control operation, then can carry out remote control at the SCADA dispatching platform and preset order, the end of standing then returns the anti-school result of remote control, and the success of anti-school then can continue to issue the remote control fill order.If the remote control item of this switch was arranged before receiving switch actuating signals, think that then switch motion is based on the true operation of SCADA remote control, mainly be the anti-school of remote control and the remote control fill order of analyzing switch to the identification of switch remote control item.
5) switch and protection actuating signal exist simultaneously; If both received the divide-shut brake signal of switch within a short period of time, received the protection actuating signal of switch corresponding device again, then switching signal is thought it may is the switch motion that is triggered by guard signal.This rule depends on system to the function of switch and the automatic coupling of guard signal, and namely system analyzes switch or its corresponding device whether this signal belongs to action automatically according to received protection actuating signal.
6) switch separating brake corresponding equipment YC=0; After the switch sub-gate signal is received by system, can from the SCADA system, reach to such an extent that the corresponding equipment remote measurement comprises P automatically, Q, I through after the time-delay of several seconds.If the remote measurement value is 0, think that then this switch actuating signals has certain confidence level.Certainly, the differentiation of null value be not strictness whether see obtained YC=0, but whether see in rational null value scope.
Switch switching signal corresponding equipment YC〉0 also be based on same consideration.
When setting false positive signal regular among the present invention, then need to consider the YC of switch separating brake corresponding device〉0; The repeated signal displacement; Satisfy self-defined mistake remote signalling condition; Situation with factory's simultaneously a large amount of remote signals displacements in station.
1. the YC of switch separating brake corresponding device〉0; If receive the YC that obtains this switch correspondence after switch sub-gate signal and the process time-delay of several seconds still greater than 0, though can not affirm fully that this signal is false positive signal, can be with this switch motion record as one of reason of reporting remote signalling by mistake.
2. repeated displacement signal; This is to design according to the operating feature of electric power system primary equipment under normal and accident condition.When the electrical network normal running, can there be the folding situation repeatedly of same switch, though when equipment debugging, may there be the signal of folding repeatedly at same equipment, can mask by the maintenance attribute of equipment.When power grid accident, because also there is the repeatedly situation of folding of line switching in the existence of ZCH, thereby but rational number of operations restriction can be set according to the rule of ZCH filter out this class signal.The switch actuating signals that surpasses the reasonable operation number of times is all thought the false positive signal that transmits repeatedly.In the system number of operations is restricted to 4 times at present, namely within a short period of time any switch the breaking-closing operating total degree can be above 4 times.
3. with the simultaneously a large amount of remote signals displacements in factory station; This is the more representational false positive signal of a class.Owing to reasons such as RTU dead electricity, RTU reset, often there is this class signal.By the certain upper limit value is set, identify the remote signals that to report by mistake.To count with the switch remote signalling of factory's station displacement simultaneously at present and be set to 12.Surpass 12 the false positive signal of thinking.
The present invention can also carry out external maintenance to rule by the interface mode except handling by internal rule storehouse mode definition signal.The external definition of rule is corresponding with the formulation of internal rule, also divides normal remote signalling rule and the design of mistake remote signalling rule, can according to circumstances formulate flexibly.Custom rule is divided into the definition of object component and auxiliary judgment conditional definition; object component is switch tool and the action attributes etc. thereof of action; the auxiliary judgment condition is relevant basis for estimation; can be other switch, disconnecting link state value, also can be the remote measurement amount of being correlated with and correlation protection information of equipment etc.Custom rule generates the regular expression statement that signal is handled by switchtype and the relevant Rule of judgment of selecting action.Custom rule can be have with or the combination of a plurality of conditional statements of logic, have higher flexibility.The external rules that defines is kept in the database.Regular export interface is provided, strictly all rules need be derived when checking in the tabulation mode the user, can select this function.
Among the present invention, through each switch tool displacement remote signalling that data analysis center is differentiated, all put sign normal or the wrong report remote signalling.Described control data corporation, to the signal after analyzing, statistics meets the number of signals of normal remote signalling and wrong report remote signalling rule respectively, utilizes man-machine interface to show analysis and the statistics of signal.For example, may be displayed on switch tool remote signalling record and the arrangement in chronological order that program run duration system captures.When showing, the result after also will analyzing is saved in the history server of SCADA system, to guarantee not losing of data.Control data corporation can provide special interface for users query history record, and the user can confirm the remote signalling unconfirmed in the historical record.By the statistical function of remote signalling record, can also check the rate of false alarm of switch tool action class remote signals easily in addition.
In the specific embodiment of system of the present invention, be platform with the ripe dispatching automation software of the DF8002 of Dongfang Electronics series, can realize and the integrated design of DF8002 SCADA dispatching platform; Hardware platform uses a high-performance computer; Operating system nucleus is Windows2000 Professional; Database uses relationship type/SQL/ client-server architecture, SYBASE, Oracle, and DB2 and MS SQL Server etc. can directly adopt the commercial data base of SCADA system among the present invention; Network configuration has independently application type for operating in independently network node, and two net designs ensure data reliability; Configuration mode is the stand-alone server application model, and namely the data of telemetry system processing service and man-machine interface realize at same microcomputer by mistake.
The present invention is technological core with real-time network topological information and operation of power networks parameter.System is structurally by independently server mode design.Server has the interface with the SCADA system interaction, has separate threads and receives the operation of power networks data that the SCADA system sends in real time, and have other thread to be responsible for the analyzing and processing work of data specially.Human-computer interaction interface and server program integrate, and make application itself compacter and efficient.
The present invention preferably operates in the network node independently with the SCADA system, and is to carry out unidirectional data to exchange with the SCADA system, namely only obtains the real-time telemetry remote signals from the SCADA system, and the result of analyzing and processing does not send to SCADA.Yet, be to have reserved the outside data-interface of issuing can be provided among the present invention, when actual needs, the analysis result of correcting errors of remote signals can be sent on the network or other platform of SCADA system.Consider that the IEC61970 standard is the cross-platform data exchange standard that generally adopts in the present electric power system, will follow the IEC61970 standard aspect the outbound data issue in the system of the present invention.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
