Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, specific embodiments of the substation mis-unlocking prevention control device of the present invention are described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the device for controlling misoperation-preventive unlocking of a transformer substation according to an embodiment of the present invention includes a telemechanical communication unit 100, a remote control command processing unit 200, an intra-station unlocking processing unit 300, an intra-station remote control processing unit 400, and an intra-station communication unit 500.
The remote communication unit 100 is configured to receive a remote control request for controlling equipment in the substation from outside the substation and transmit the remote control request to the remote control command processing unit 200. The remote control request sent to the substation may come from a remote controller or remote control device dedicated to control of the substation, or may come from a remote control terminal, such as a computer for control. The telecontrol communication unit 100 is mainly used for receiving a remote control signal, receiving an external signal into the transformer substation, processing the signal by other internal processing units, and correspondingly controlling equipment in the transformer substation according to the remote control signal.
The signal received by the telemechanical communication unit 100 is first sent to the remote control command processing unit 200, and the remote control command processing unit 200 is configured to analyze a remote control request to obtain an unlocking request to be sent to the anti-misoperation system of the substation and a remote control command to be sent to the measurement and control device of the substation. The remote control signal analysis method is a very key component, and after receiving the remote control signal, the remote control signal is analyzed to analyze specific in-station equipment to be controlled in the remote control signal. After the device to be specifically controlled is determined, the lock to be unlocked is determined, so that the remote control command processing unit 200 can generate an unlocking request of the error prevention system corresponding to the remote control signal and can also generate a remote control command to be used for controlling the specific device in the station, wherein the remote control command is contained in the remote control signal. The remote control command processing unit 200 sends the generated unlocking request to the in-station unlocking processing unit 300; the remote control command is sent to the in-station remote control processing unit 400.
After receiving the unlocking request analyzed by the remote control command processing unit 200, the in-station unlocking processing unit 300 sends the unlocking request to the anti-misoperation system of the substation. And the anti-misoperation system of the transformer substation unlocks corresponding locks in the station according to the received unlocking request. Of course, the unlocking of the anti-error system may be successful or may fail. Specifically, after the anti-misoperation system receives the unlocking request, whether the locks related to the unlocking request are in a controllable state or not can be judged, if some locks cannot be opened due to limitation of high authority caused by product faults and the like, the locks are in an uncontrollable state, and in addition, if the locks related to the unlocking request are in faults, the intelligent electronic equipment cannot unlock the locks, and the faulty locks are also in an uncontrollable state. If the anti-misoperation system judges that the lock involved in the unlocking request is in a controllable state, normal unlocking operation can be carried out, and the unlocking is successful. However, if the anti-misoperation system determines that the lock involved in the unlocking request is in an uncontrollable state, the anti-misoperation system will fail to unlock. At this time, the error prevention system also returns unlocking failure information.
Preferably, when the lock cannot be unlocked randomly due to some faults, in one embodiment, the anti-misoperation system further has a function of judging the fault level of the lock, and can judge the fault level of the lock after receiving the unlocking request, and when the fault level exceeds a preset level, the anti-misoperation system returns unlocking failure information and does not unlock the lock. And when the fault level does not exceed the preset level, the fault authority setting is crossed, the lock involved in the unlocking request is forcibly unlocked, and at the moment, the anti-misoperation system still can be successfully unlocked.
In the control system of this embodiment, the remote control command processing unit 200 unlocks two requests according to the received command, one of the two requests is sent to the in-station unlocking processing unit 300 for sending an unlocking request to the in-station error prevention system, and the other request is sent to the in-station remote control processing unit 400. However, the in-station remote control processing unit 400 does not directly send the remote control command to the measurement and control device in the substation after receiving the request, but waits for the unlocking feedback information of the anti-misoperation system. Only after the anti-misoperation system is successfully unlocked, the in-station remote control processing unit 400 sends the remote control command analyzed by the remote control command processing unit 200 to the measurement and control device.
Preferably, the in-station unlocking processing unit 300 is further configured to receive an unlocking result of the anti-misoperation system, and send the received unlocking result to the remote control command processing unit 200. When the remote control command processing unit 200 processes the remote control request, it first maps the received remote control request to an unlocking request sent to the error prevention system of the substation. And then waits for the intra-station unlock processing unit 300 to return the unlock result. And the remote control command processing unit maps the remote control command into a remote control command sent to the measurement and control device of the transformer substation after the anti-misoperation system is successfully unlocked. When the anti-misoperation system fails to unlock, the remote control command processing unit 200 sends a remote control failure response to the outside of the station through the telemechanical communication unit 100. Or directly send an unlock failure response.
The in-station unlocking processing unit 300 and the in-station remote control processing unit 400 are both in communication with the relevant devices in the substation through the in-station communication unit 500, including the transmission of requests and the feedback of execution results of the relevant devices. For example, the intra-station unlocking processing unit 300 may communicate with the intra-station error prevention system through the intra-station communication unit 500; the in-station remote control processing unit 400 communicates with the instrumentation devices in the substation through the in-station communication unit 500.
As can be seen from the foregoing description, after receiving a remote control request, the substation anti-misoperation unlocking control device according to the embodiment of the present invention does not directly send the remote control request to the relevant device in the intelligent substation, but first generates an unlocking request for the related device to be remotely controlled. The unlocking request is sent to the anti-misoperation system of the substation, and the real remote control command is sent to the measurement and control device by the in-station remote control processing unit 400 through the in-station communication unit 500 only after receiving the unlocking success information of the anti-misoperation system. Therefore, the remote control of the outside to the inside of the transformer substation can be carried out only through the unlocking judgment and control of the anti-misoperation system. Therefore, electrical misoperation can be effectively prevented, and the safe operation of the power system is ensured.
It should be further noted that, in the device for controlling locking by mistake for preventing unlocking of a transformer substation according to the embodiment of the present invention, the mistake prevention system of the transformer substation may feed back information on whether unlocking is successful. In a general anti-misoperation system, information of success or failure of unlocking is directly fed back to the in-station unlocking request unit 300, and the in-station unlocking request unit 300 sends the fed-back unlocking result to the remote control command processing unit 200. After receiving the unlocking result, the remote control command processing unit 200 judges whether the unlocking result is successful information, and sends a remote control command to the measurement and control device after the unlocking is successful; of course, if it is determined that the unlocking failure information is the unlocking failure information, the remote control command is not sent to the measurement and control device, that is, the remote control of the internal equipment of the substation is interrupted, and at this time, the remote control device sends the unlocking failure information or responds to the remote control equipment outside the substation in response to the remote control failure through the telecontrol communication unit 100.
Of course, as an implementation manner, the remote control command processing unit may also directly map the remote control request into an unlocking request and a remote control command, the in-station unlocking processing unit 300 may directly send the received anti-misoperation system unlocking result to the in-station remote control processing unit 400, and the in-station remote control processing unit may directly send the remote control command to the measurement and control device of the substation and wait for the remote control result when the unlocking is successful.
Preferably, the in-station remote control processing unit 400 is further configured to receive a remote control result of the measurement and control device in the substation, and send the remote control result to the remote control command processing unit 200. After receiving the remote control result, the remote control command processing unit 200 sends a remote control response signal to the outside of the substation through the telemechanical communication unit. And after receiving the remote control result, the remote control command processing unit 200 maps the remote control request to a locking request sent to the anti-misoperation system of the substation, and sends the locking request to the in-station unlocking processing unit 300, and after receiving the locking request, the in-station unlocking processing unit 300 sends the locking request to the anti-misoperation system through the in-station communication unit 500. Here, the remote control result of the measurement and control device received by the in-station remote control processing unit 400 is a result of primary device control that is completed by the measurement and control device and then to the intelligent terminal after the in-station remote control processing unit 400 sends a remote control instruction to the measurement and control device. Of course, the result of this device control may be either a successful device remote control or a failed device remote control. However, in order to ensure the safety of the electrical operation inside the substation, no matter the equipment is successfully or unsuccessfully remotely controlled, after the remote control is completed once, the anti-misoperation system of the substation performs locking operation on the related lock. In the control system of the embodiment of the present invention, the locking process is implemented by sending a locking request to the anti-misoperation system through the in-station unlocking processing unit 300, and the anti-misoperation system performs locking control on the corresponding lock after receiving the locking request.
Those skilled in the art will understand that the locking request sent by the station-based unlocking processing unit 300 and the unlocking request sent before should correspond to each other, that is, the lock involved in the locking request and the lock involved in the unlocking request are generally the same.
As can be seen from the foregoing description, the remote control processing unit 400 in the station receives the remote control result fed back by the measurement and control device. As also described above, the remote control result may be a remote control success or a remote control failure, and the in-station remote control processing unit 400 transmits the remote control result to the remote control command processing unit 200 regardless of the remote control success or the remote control failure. And after receiving the remote control result, the remote control command processing unit 200 further transmits a remote control response signal to the outside of the substation through the telecontrol communication unit 100. Of course, the remote control response signal sent to the outside of the substation is generally sent to the device sending the remote control request, that is, after the remote control device outside the substation sends the remote control request to the substation, the remote control result returned by the substation is received after a period of time, and it is clear from the remote control result that whether the remote control on the device inside the substation is successful or failed. And the communication between the substation and its external devices is realized through the telecontrol communication unit 100.
In a specific embodiment of the substation anti-misoperation unlocking control device, as shown in fig. 2, the telecontrol communication unit 100 is an IEC60870-101 telecontrol communication unit 100 that is composed of a first network card 110 (here, "first" is only used for distinguishing a next network card, and has no special meaning, that is, "first network card 110" only represents that it is a network card) and a 101 protocol processing unit 120. The 101 protocol processing unit 120 is a software module. Accordingly, the remote control command processing unit 200, the in-station remote control processing unit 400, and the in-station unlock processing unit 300 are also software modules, respectively. The in-station communication unit 500 is similar to the telecontrol communication unit 100, and is an IEC61850 communication unit formed by a second network card 510 (here, "second" is used only as the first network card 110 for distinguishing the telecontrol communication unit 100, and has no special meaning, that is, "second network card 510" only represents that it is a network card) and an IEC61850 protocol processing unit 520. Therein, the IEC61850 protocol processing unit 520 is also configured as a software module. Software modules in the control system, such as the IEC61850 protocol processing unit 520, can be stored in a memory in the control system.
Those skilled in the art can understand that when the first network card 110 in the telecontrol communication unit 100 and the second network card 510 in the in-station communication unit 500 are selected, the same model of network card can be selected, and different models of network cards can be selected according to performance requirements.
In this specific example, when there is an external remote control request, the first network card 110 in the remote communication unit 100 receives an ex-station IEC60870-101 remote control message, and the 101 protocol processing unit 120 decodes the IEC60870-101 remote control message received by the first network card 110 through an IEC60870-101 protocol, and sends the decoded remote control request to the remote control command processing unit 200. The remote control command processing unit 200 maps the remote control request to an unlocking request to the error prevention system. The in-station unlocking processing unit 300 sends an unlocking command to the anti-misoperation system through the IEC61850 communication unit; and transmits the unlocking success result to the remote control command processing unit 200. After receiving the unlocking success result, the remote control command processing unit 200 maps the remote control request into a remote control command sent to the measurement and control device, and sends the remote control command to the in-station remote control processing unit 400, and the in-station remote control processing unit 400 sends the remote control command to the measurement and control device through the IEC61850 communication unit; and transmits the remote control result to the remote control command processing unit 200. After receiving the remote control structure, the remote control command processing unit 200 maps the remote control request received first to a lock request, and transmits the lock request to the in-station unlock processing unit 300. After receiving the locking request, the in-station unlocking processing unit 300 sends the locking request to the anti-misoperation system through the in-station communication unit 500. And after receiving the remote control result, the remote control command processing unit 200 transmits the remote control result to the IEC60870-101 telecontrol communication unit 100, and the 101 protocol processing unit 120 in the IEC60870-101 telecontrol communication unit 100 encodes the remote control response into an IEC60870-101 remote control response message and requests to send the IEC60870-101 remote control response message to the outside of the station through the first network card 110.
Based on the same inventive concept, the transformer substation anti-misoperation unlocking control method provided by the embodiment of the invention has the advantages that the principle of solving the problems is similar to the function of the transformer substation anti-misoperation unlocking control device, so that the implementation of the method can be realized through the units of the system, and repeated parts are not repeated.
As shown in fig. 3, the method for controlling the mis-unlocking prevention of the transformer substation according to an embodiment of the present invention includes the following steps:
and S100, receiving a remote control request for controlling equipment in the transformer substation, which is sent from the outside of the transformer substation.
And S200, resolving the remote control request into an unlocking request sent to an anti-misoperation system in the transformer substation and a remote control command sent to a measurement and control device in the transformer substation.
And S300, sending an unlocking request to the anti-misoperation system.
And S400, after the anti-misoperation system is successfully unlocked, sending the remote control command to the measurement and control device.
According to the method for controlling the misoperation-preventive unlocking of the transformer substation, after a remote control request outside the transformer substation is received, the remote control request is firstly analyzed into an unlocking request for an misoperation-preventive system and a remote control command for a measurement and control device, the unlocking request is firstly sent to the misoperation-preventive system inside the transformer substation, and the remote control command is sent to the measurement and control device to control equipment inside the transformer substation only after the misoperation-preventive system is successfully unlocked. Therefore, when the equipment in the transformer substation is controlled through the external remote control device, the related lock is unlocked and controlled through the anti-misoperation system in the transformer substation, the interface operation of the external remote control operation of the transformer substation and the anti-misoperation system in the transformer substation is realized through the method, the protection effect of the transformer substation of the anti-misoperation system can be guaranteed, the remote control operation outside the substation is prevented from being supervised by the anti-misoperation system in the substation, a command is sent to the measurement and control device directly through a substation control layer bus of the transformer substation, the electrical misoperation of the equipment in the transformer substation is effectively prevented, and the safe operation of a power system is guaranteed.
Specifically, in the implementation process of the method, communication between the interior of the substation and the external remote control device can be realized through the telecontrol communication unit 100 in the substation, for example, the communication can be performed through the first network card 110 and an IEC60870-101 protocol or an IEC60870-104 protocol; the communication between the inside and the measurement and control device can be realized through the station communication unit 500 inside, for example, through the second network card 510 and the IEC61850 protocol. And other related steps can be realized by arranging corresponding software modules inside the substation.
Further, after the anti-error system receives the unlocking request, the corresponding lock can be unlocked, but the unlocking failure can also occur. Once the unlocking fails, the remote control operation is stopped. At this time, the unlocking failure information may be sent to the external remote control device, and of course, the remote control operation of this time fails, or the remote control failure information may be directly sent. But the unlocking failure information is sent to ensure that the problem occurs in which step, so that the reason can be found more conveniently to carry out remote control operation again.
Preferably, after the remote control operation of the measurement and control device is completed, a locking request can be further sent to the anti-misoperation system. Therefore, the anti-misoperation system in the transformer substation can perform locking operation on the previously unlocked lock, and the safety of the internal equipment in the transformer substation is ensured.
It should be noted that, the completion of the remote control operation of the measurement and control device includes success of remote control and failure of remote control, and in short, after a remote control command is sent to the measurement and control device, the measurement and control device waits for receiving the return information of the measurement and control device. If the measurement and control device cannot complete the operation according to the remote control command for some reasons (such as equipment failure), the measurement and control device can also return the information of remote control failure within a certain time. After receiving the information of remote control failure, even if a remote control operation is completed, a locking request is sent to the anti-misoperation system, and the lockset opened due to the remote control operation is closed in time. And the safety of the internal equipment of the transformer substation is ensured.
Because the remote control operation on the measurement and control device may be successful or may fail, in one embodiment, the method further comprises the step of judging whether the remote control operation on the measurement and control device is successful, and if so, sending a remote control success response message to the outside of the transformer substation; and if not, sending remote control failure response information to the outside of the transformer substation. This enables the external remote control device to know the remote control result definitely, facilitating the further operation.
Fig. 4 shows a specific example of the method for controlling the anti-misoperation unlocking of the transformer substation according to the present invention. The method specifically comprises the following steps:
s101, receiving a remote control request.
And S102, mapping the remote control request into an unlocking request sent to the first intelligent electronic device and a remote control command sent to the measurement and control device. The first intelligent electronic device is a part for intelligent control of the transformer substation, and intelligent control of the internal equipment of the transformer substation is finally realized through the intelligent electronic device. In the step, when the remote control request is implemented, the remote control request is firstly sent to the anti-misoperation system in the transformer substation, and when the anti-misoperation system controls (unlocks and locks) the lockset, the remote control request is realized through the first intelligent electronic device.
And S103, sending an unlocking command to the first intelligent electronic device. The unlocking command is an unlocking command for the corresponding lock generated according to the unlocking request generated in step S102.
S104, detecting or judging whether the unlocking of the anti-misoperation system is successful, and executing the step S105 when the unlocking is successful; when the unlocking fails, step S109 is executed.
And S105, sending the remote control command to a measurement and control device in the transformer substation.
S106, detecting or judging whether the remote control of the measurement and control device is successful, and if so, executing a step S107; if not, go to step S107'.
