Technical field
The present invention relates to a kind of scheduling station and do not rely on the method that the accident resultant signal realizes that emergency stop valve trip is judged.
Background technology
Scheduling energy management system (EMS) realizes that in substation accident tripping operation phonic warning and judge are so the method for picture generally has two kinds: 1, the total lock of station accident+our station switch separating brake entirely, 2, the total lock of interval accident+this interval switch separating brake, both all need satisfy the regular hour requirement simultaneously.Above dual mode all requires total timely, the precision maneuver of accident, and there is multiple mode in the transformer station scene to the total generating mode of accident, and is totally as follows: 1, software synthesis mode.To full station all protect at interval action message carry out " or " calculate or to all at interval accidents always carry out " or " calculate, it is total that arbitrary action all triggers full station accident.Existing problems: always accident involution in time, even adopt in short-term runback give the credit to can, leak the risk of alarming in also existing during this period of time.2, hard circuit type.Accident little bus in full station on (HHJ) back, position, back is closed in all switch trip position (TWJ) series connection of full station, and it is total that arbitrary switch failure tripping operation all triggers full station accident.Existing problems: have accident involution in time always equally, must carry out manual brake separating by all switches, full station accident always could involution after the correspondence of the position of the switch.
Therefore main website carries out emergency stop valve trip to be judged, accident total (station or interval entirely) action must be arranged, and has relatively high expectations blanking time with the switch sub-gate signal, usually in level second.And combine at present from transformer station's observing and controlling separately the interval of configuration (110kV and more than) can satisfy time requirement substantially; but not exclusively meet the demands for the time between the device accident summation switch separating brake of low pressure (35kV and following) protection observing and controlling unification; and 35kV and following interval have comprised that most users at interval; as can not in time finding the circuit dead electricity and sending electricity fast, just can not satisfy the supreme management expectancy of enterprises service.
Summary of the invention
The invention provides a kind of scheduling station and do not rely on the method that the accident resultant signal realizes that emergency stop valve trip is judged, it can make scheduling station reach timely, comprehensive, correct emergency stop valve trip judgement.
The present invention has adopted following technical scheme: a kind of scheduling station does not rely on the method that the accident resultant signal realizes that emergency stop valve trip is judged, it may further comprise the steps: step 1, after the switch failure tripping operation of transformer station, can upload switch separating brake information, protection action message, Switch main body information, device warning information and accident total information, and the load current of circuit can change also; Step 2, first step deterministic process is to judge whether the infrastructure device in the transformer station normally puts into operation, if putting into operation, infrastructure device is in abnormal condition, then finish deterministic process, this tripping operation is because the infrastructure device of transformer station causes, if putting into operation, infrastructure device is in normal condition, then enter the second step deterministic process, the process that second step was judged is to check 15 minutes interior load currents that occur in inherent this interval forward, when load current Ia＜0.2A, then finish deterministic process, this tripping operation is because too small the causing of load current in this interval, if during Ia 〉=0.2A, then enters the 3rd and goes on foot deterministic process, the 3rd goes on foot to judge it is that the information that whether our station has protection to move in 1 minute before and after checking occurs, if the information of protection action occurs, then finish deterministic process, this tripping operation is owing to not protecting action to cause, if there is the protection action message to occur, then enter the 4th step deterministic process; The 4th step deterministic process is to check whether the infrastructure device in the transformer station is put board, if put board, then finish to judge, this tripping operation causes owing to having occurred putting the board phenomenon, if the board phenomenon do not occur putting, then enter the 5th step deterministic process, the 5th step deterministic process is to check whether straighforward operation is arranged, if straighforward operation arranged then just finish deterministic process, this tripping operation causes owing to straighforward operation occurring, if the straighforward operation phenomenon do not occur, then this tripping operation belongs to emergency stop valve trip, and then deterministic process finishes.
The present invention has following beneficial effect: after having adopted above technical scheme, the present invention can not rely on accident total information realization scheduling station system and correctly judge emergency stop valve trip.The present invention not only can realize the judgement of main website emergency stop valve trip at all, and can differentiate automatically that signal in the capital construction process is checked, service work circuit breaker accident separating brake information of putting under the abnormal running situations such as accident separating brake information that situation such as board produces not yet in effect, greatly improve the main station monitoring personnel to the disposal ability of emergency stop valve trip event, the more important thing is and to reduce the equipment interruption duration, avoid the dispute of powering.Aspect maintenance, operational management meaning, it realizes effectively improving and replenishing to existing emergency stop valve trip implementation, and possesses actual dissemination.Therefore by the application of this patent, reach timely, comprehensive, the correct emergency stop valve trip that carries out of scheduling station and judge.The present invention need not the accident total information and comprises that accident summation interval, full station accident is total, just do not exist yet transformer station's information is uploaded the real-time requirement, particularly old transformer station does not need any transformation just can realize main website emergency stop valve trip judgement, and judged result is more accurate and comprehensive, can solve because signal in the capital construction process is checked, service work circuit breaker accident separating brake information of putting under the abnormal running situations such as accident separating brake information that situation such as board produces not yet in effect.
