The embodiments of the present invention will be described in detail with reference to the drawings and examples, so that how to implement the technical means for solving the technical problems and achieving the technical effects of the present invention can be fully understood and implemented.
The following description will first be made of the switch device applicable to a substation according to the present disclosure, and please refer to fig. 1, in which fig. 1 shows a device block diagram of the switch device applicable to a substation according to the present disclosure.
The invention is particularly suitable for transformer substations, Intelligent Electronic Devices (IEDs) in the transformer substations transmit General Object Oriented Substation Events (GOOSE) to other Intelligent Electronic devices through the exchanger Device provided by the invention, and the exchanger Device which initially triggers the abnormal state event can be rapidly and accurately known through the design of the exchanger Device, so that maintenance personnel can maintain the exchanger Device or the connection between the exchanger devices.
The present invention discloses a switch device 10 suitable for a transformer substation, which comprises: a packet receiving module 11, a packet transmitting module 12, a packet access control module 13, a packet judging module 14, a request transmitting module 15, an alert module 16, a request receiving module 17, a request judging module 18, and a request reply transmitting module 19.
The switch device 10 may be connected to an intelligent electronic device or another switch device 10 to provide the intelligent electronic device to transmit the global target-oriented substation event packet to another intelligent electronic device, i.e. the packet receiving module 11 of the switch device 10 may receive the global target-oriented substation event packet from the intelligent electronic device or an upstream switch device (for distinguishing from the switch device 10, the other switch device 10 transmits the global target-oriented substation event packet to the switch device 10 and is referred to as an upstream switch device).
When the packet receiving module 11 of the switch device 10 receives the rgb event packet, the packet access control module 13 of the switch device 10 copies the rgb event packet and accesses the copied rgb event packet by the packet access control of the ethernet switch chip, thereby performing the determination process of the subsequent packet.
Meanwhile, the switch device 10 establishes a packet port mapping table, where the packet port mapping table is a mapping relationship between the duplicated rgd event packet and the input port, and specifically, assuming that the first input port of the switch device 10 receives the first rgd event packet and duplicates it into the first duplicated rgd event packet, the switch device 10 stores the first duplicated rgd event packet and the first input port into the packet port mapping table at the same time, which is only an example and is not intended to limit the application scope of the present invention.
The packet transmission module 12 of the switch device 10 can transmit the general-purpose destination-oriented substation event packet to the intelligent electronic device or a downstream switch device (for the purpose of distinguishing from the switch device 10, the switch device 10 transmits the general-purpose destination-oriented substation event packet to another switch device 10 and is referred to as a downstream switch device), and the intelligent electronic device can transmit the general-purpose destination-oriented substation event packet to another intelligent electronic device through the packet receiving module 11 of the switch device 10 and the packet transmission module 12 of the switch device 10.
After the packet access control module 13 of the switch device 10 copies and accesses the copied generic target-oriented substation event packet, the packet determination module 14 of the switch device 10 determines the contents of the TATL, sqNum, APP ID and goCBRef fields in the copied generic target-oriented substation event packet, so as to determine whether the copied generic target-oriented substation event packet triggers an abnormal state event of Timeout, sampled and Sequence recorder.
Specifically, the packet determining module 14 of the switch device 10 may determine whether the replicated generic target-oriented substation event packet triggers a Timeout abnormal event according to the value of the TATL field in the replicated generic target-oriented substation event packet; the grouping judgment module 14 of the switch device 10 may judge whether the event grouping of the replicated generic target-oriented substation triggers an abnormal state event of the Sequence dispatcher according to the value of the sqNum field in the event grouping of the replicated generic target-oriented substation; the packet determining module 14 of the switch device 10 may determine whether the copied generic target-oriented substation event packet triggers an abnormal state event of sampled according to the APP ID and the content of the goCBRef field in the copied generic target-oriented substation event packet, which is only for illustration and is not limited to the application scope of the present invention.
When the grouping determination module 14 of the switch device 10 determines that the event grouping of the replicated generic target-oriented substation triggers an abnormal state event, a corresponding abnormal state event confirmation request is generated according to the abnormal state event triggered by the event grouping of the replicated generic target-oriented substation, and the request transmission module 15 of the switch device 10 transmits the abnormal state event confirmation request to the corresponding upstream switch device according to the grouping port mapping table established by the switch device.
Specifically, assuming that the packet determining module 14 of the switch device 10 determines that the time out abnormal event triggered by the replicated generic target-oriented substation event packet is generated, a time out abnormal event confirmation request is generated according to the time out abnormal event, and the request transmitting module 15 of the switch device 10 transmits the time out abnormal event confirmation request to the corresponding upstream switch device, which is only an example and is not intended to limit the application scope of the present invention.
If the switch device 10 fails to receive a Ready response from the corresponding upstream switch device within a predetermined time, the alert module 16 of the switch device 10 generates and sends an alert message according to the abnormal state event and the packet port mapping table, which indicates that the switch device 10 is the switch device 10 that initially triggered the abnormal state event; if the switch device 10 receives a ready response from the corresponding upstream switch device within a predetermined time, the switch device 10 and the upstream switch device both trigger the same abnormal state event, i.e. the switch device 10 does not trigger the abnormal state event initially, and at this time, the alarm module 16 of the switch device 10 will not generate and send an alarm message according to the abnormal state event and the packet port mapping table, which indicates that the switch device 10 is not the switch device 10 that triggered the abnormal state event initially.
Specifically, it is assumed that the event packet triggering abnormal state event of the duplicated generic target-oriented substation is a Timeout abnormal state event and the event packet triggering abnormal state event of the first duplicated generic target-oriented substation is related to the first input port, and the alert message generated by the alert module 16 of the switch device 10 is the event packet triggering Timeout abnormal state event of the first generic target-oriented substation received from the first input port, which is only illustrated by way of example and is not limited to the application scope of the present invention.
The request receiving module 17 of the switch device 10 receives the abnormal state event confirmation request from the downstream switch device corresponding to the received general purpose destination guide substation event packet, and determines whether the switch device 10 triggers the abnormal state event identical to the abnormal state event confirmation request through the request judging module 18 of the switch device 10, if the request judging module 18 of the switch device 10 determines that the switch device 10 triggers the abnormal state event identical to the abnormal state event confirmation request, a ready response is generated, and the request reply transmitting module 19 of the switch device 10 transmits the ready response generated by the request judging module 18 of the switch device 10 to the corresponding downstream switch device, if the request judging module 18 of the switch device 10 determines that the switch device 10 does not trigger the abnormal state event identical to the abnormal state event confirmation request, no ready response is generated and the request reply transmission module 19 of the switch device 10 will not transmit a ready response to the corresponding downstream switch device.
Next, an operation system and a method according to an embodiment of the present invention will be described with reference to fig. 2A, fig. 2B, fig. 3 and fig. 4, wherein fig. 2A and fig. 2B are flow charts of a method for warning a fault of a substation switch device according to the present invention; fig. 3 shows a schematic diagram of the device structure of the invention suitable for fault warning of a substation exchanger device; fig. 4 illustrates the switch device establishment packet port correspondence representation intent of the present invention applicable to fault alerting of substation switch devices.
The first intelligent electronic device 21 transmits the first and second generic-target-oriented substation event packets 31 and 32 to the third intelligent electronic device 23, the first to fifth switch devices 41 to 45 respectively receive the first and second generic-target-oriented substation event packets 31 and 32 (step 101), the first to fifth switch devices 41 to 45 respectively transmit the first and second generic-target-oriented substation event packets 31 and 32 (step 102), and the first to fifth switch devices 41 to 45 respectively duplicate the first and second generic-target-oriented substation event packets 31 and 32 to provide subsequent access and determination (step 103).
The fourth intelligent electronic device 24 transmits the second generic destination-oriented substation event packet 32 to the second intelligent electronic device 22, and establishes the first packet port mapping table 51 in the first switch device 41, as shown in part (a) of fig. 4, the second packet port mapping table 52 in the second switch device 42, as shown in part (B) of fig. 4, the third packet port mapping table 53 in the third switch device 43, as shown in part (C) of fig. 4, the fourth packet port mapping table 54 in the fourth switch device 44, as shown in part (D) of fig. 4, and the fifth packet port mapping table 55 in the fifth switch device 45, as shown in part (E) of fig. 4.
The second switch device 42, the third switch device 43, the fourth switch device 44 and the fifth switch device 45 respectively determine that the copied first generic-target-oriented substation event packet has triggered the abnormal-state event of Timeout, and at this time, the second switch device 42, the third switch device 43, the fourth switch device 44 and the fifth switch device 45 respectively generate the Timeout abnormal-state event confirmation request 61 according to the abnormal-state event of Timeout (step 104).
The second switch device 42 can send the Timeout abnormal event acknowledgement 61 to the third switch device 43 according to the second packet port mapping table 52 (step 105, step 107), the fourth switch device 44 can send the Timeout abnormal event acknowledgement 61 to the third switch device 43 according to the fourth packet port mapping table 54 (step 105, step 107), and the fifth switch device 45 can send the Timeout abnormal event acknowledgement 61 to the third switch device 43 according to the fifth packet port mapping table 55 (step 105, step 107).
Since the third switch device 43 and the second switch device 42, the fourth switch device 44, and the fifth switch device 45 all trigger the Timeout abnormal event confirmation request 61, when the third switch device 43 receives the Timeout abnormal event confirmation request 61 from the second switch device 42, the fourth switch device 44, and the fifth switch device 45, respectively, the third switch device 43 generates the ready response 62 (step 108) and transmits the ready response to the second switch device 42, the fourth switch device 44, and the fifth switch device 45, respectively (step 109).
The second switch device 42, the fourth switch device 44, and the fifth switch device 45 can receive the ready response 62 from the third switch device 43 within the preset time, the second switch device 42 will not generate and send out the alert message according to the Timeout abnormal state event and the second packet port mapping table 52, the fourth switch device 44 will not generate and send out the alert message according to the Timeout abnormal state event and the fourth packet port mapping table 54, and the fifth switch device 45 will not generate and send out the alert message according to the Timeout abnormal state event and the fifth packet port mapping table 55.
The third switch device 43 can transmit the Timeout abnormal event confirmation request 61 to the first switch device 41 according to the third packet port mapping table 53 (step 105, step 107), however, the first switch device 41 does not trigger the Timeout abnormal event, when the first switch device 41 receives the Timeout abnormal event confirmation request 61 from the third switch device 43, the first switch device 41 will not generate the ready response, i.e. the third switch device 43 fails to receive the ready response from the first switch device 41 within the preset time, the third switch device 43 will generate and send out the alert message as "the first generic target guided substation event packet received from the first input port triggers the Timeout abnormal event" according to the Timeout abnormal event and the third packet port mapping table 53 (step 106), thereby the maintenance personnel can check the first switch device 41, the second switch device, and the third packet port mapping table 53, The third switch device 43 or the connection between the first switch device 41 and the third switch device 43 is maintained.
The first switch device 41, the third switch device 43, the fourth switch device 44, and the fifth switch device 45 respectively determine that the duplicated second generic destination-oriented substation event packet has triggered the Sequence dispatcher abnormal state event, and at this time, the first switch device 41, the third switch device 43, the fourth switch device 44, and the fifth switch device 45 respectively generate the Sequence dispatcher abnormal state event confirmation request 63 according to the Sequence dispatcher abnormal state event (step 104).
The first switch device 41 may forward the Sequence reorder abnormal state event confirmation request 63 to the third switch device 43 according to the first packet port mapping table 51 (step 105, step 107), the fourth switch device 44 may forward the Sequence reorder abnormal state event confirmation request 63 to the third switch device 43 according to the fourth packet port mapping table 54 (step 105, step 107), and the fifth switch device 45 may forward the Sequence reorder abnormal state event confirmation request 63 to the third switch device 43 according to the fifth packet port mapping table 55 (step 105, step 107).
Since the third switch device 43 and the first, fourth and fifth switch devices 41, 44 and 45 trigger the Sequence reorder abnormal state event confirmation request 63, when the third switch device 43 receives the Sequence reorder abnormal state event confirmation request 63 from the first, fourth and fifth switch devices 41, 44 and 45, respectively, the third switch device 43 generates the ready response 64 (step 108) and transmits it to the first, fourth and fifth switch devices 41, 44 and 45, respectively (step 109).
The first switch device 41, the fourth switch device 44, and the fifth switch device 45 can receive the ready response 64 from the third switch device 43 within the preset time, the first switch device 41 will not generate and send out the warning message according to the Sequence reorder abnormal state event and the first packet port mapping table 51, the fourth switch device 44 will not generate and send out the warning message according to the Sequence reorder abnormal state event and the fourth packet port mapping table 54, and the fifth switch device 45 will not generate and send out the warning message according to the Sequence reorder abnormal state event and the fifth packet port mapping table 55.
The third switch device 43 can transmit the Sequence disorder abnormal state event confirmation request 63 to the second switch device 42 according to the third packet port mapping table 53 (step 105, step 107), however, the second switch device 42 does not trigger the Sequence disorder abnormal state event, when the second switch device 42 receives the Sequence disorder abnormal state event confirmation request 63 from the third switch device 43, the second switch device 42 will not generate a ready response, that is, the third switch device 43 fails to receive the ready response from the second switch device 42 within a preset time, the third switch device 43 will generate and issue a warning message as "the second general target oriented substation event packet received from the second input port triggers the Sequence disorder abnormal state event" according to the Sequence disorder abnormal state event and the third packet port mapping table 53 (step 106), thus, the maintenance personnel can maintain the second switch device 42, the third switch device 43 or the connection between the second switch device 42 and the third switch device 43.
In summary, it can be seen that the difference between the present invention and the prior art is that the switch device copies and accesses the generic target-oriented substation event packet, when the switch device determines that the generic target-oriented substation event packet triggers an abnormal state event, the switch device generates an abnormal state event confirmation request and transmits the abnormal state event confirmation request to the corresponding upstream switch device, and when the switch device fails to receive a ready response from the upstream switch device, the switch device sends an alert message.
By the technical means, the problem that the existing switch device suitable for the transformer substation is poor in fault detection efficiency in the prior art can be solved, and the technical effect of quickly and accurately obtaining the switch device of the initial trigger abnormal state event so as to be convenient to maintain is achieved.
