Example one
Fig. 1 is a structural block diagram of a substation fault processing system according to an embodiment of the present disclosure, which may be applied to a scenario of performing fault identification and fault processing on equipment in a substation. As shown in fig. 1, the substation fault handling system may include a dedicated line channel monitoring module 10, a network channel monitoring module 20, and a fault handling module 30. Wherein the content of the first and second substances,
the dedicated line channel monitoring module 10 is configured to monitor a communication frequency of a dedicated line channel of the substation, and determine a communication state of the dedicated line channel according to the communication frequency.
Illustratively, the communication status may include normal communication or interrupted communication. The normal communication refers to a state that the communication of the two end devices communicating through the private line channel is normal communication; the communication interruption refers to a situation in which communication of the two-end device communicating via the dedicated line channel is interrupted, for example, when the in-station device or the communication device fails, the communication is interrupted.
In an embodiment, the dedicated line channel monitoring module 10 is specifically configured to: when the communication frequency is monitored to fluctuate continuously within a set range, the communication state of the special line channel is judged to be normal; when it is monitored that the communication frequency remains unchanged in the set time period, it is determined that the communication state of the dedicated line channel is communication interruption, and a communication interruption signal is output to the fault processing module 30.
Specifically, when the devices communicating via the dedicated channel are all normal, the communication frequency of the dedicated channel is continuously jittered within a certain set range (for example, a range of 1700 ± 400), and therefore, when the dedicated channel monitoring module 10 detects that the communication frequency of the dedicated channel is continuously fluctuated within the set range, it is determined that the communication state of the dedicated channel is normal, and at this time, the dedicated channel monitoring module 10 does not output a signal; otherwise, when the dedicated line channel monitoring module 10 detects that the communication frequency of the dedicated line channel remains unchanged (no jitter) within the set time period, it is determined that the communication state of the dedicated line channel is communication interruption, and at this time, the dedicated line channel monitoring module 10 may output a communication interruption signal to the fault processing module 30.
In a further embodiment, the dedicated channel may include a positive electrical channel and a negative electrical channel, and as shown in the schematic architecture diagram of the substation fault handling system in fig. 2, the dedicated channel monitoring module 10 may include a first frequency monitoring module and a second frequency monitoring module. The first frequency monitoring module is used for monitoring a first communication frequency of the positive electric channel and determining the communication state of the positive electric channel according to the first communication frequency; the second frequency monitoring module is used for monitoring a second communication frequency of the negative electricity channel and determining the communication state of the negative electricity channel according to the second communication frequency.
Specifically, a positive electrical signal transmitting line (which may be denoted as T +, T, i.e., transmit) and a positive electrical signal receiving line (which may be denoted as R +, R, i.e., receive) may be included in the positive electrical channel, and T + and R + are a set of positive electrical communication lines; a negative electrical signal transmitting line (which may be denoted as T-) and a negative electrical signal receiving line (which may be denoted as R-) may be included in the negative electrical channel, T-and R-being a set of negative electrical communication lines. As shown in the schematic diagram of the substation architecture of fig. 3, the dedicated channel monitoring module 10 may include a first frequency monitoring module for monitoring a first communication frequency of a positive channel composed of T + and R +, and a second frequency monitoring module for monitoring a second communication frequency of a negative channel composed of T-and R-, where the first frequency monitoring module may determine a communication state of the positive channel according to the monitored first communication frequency, and the second frequency monitoring module may determine a communication state of the negative channel according to the monitored second communication frequency. When any one of the first frequency monitoring module and the second frequency monitoring module monitors that the communication frequency is unchanged in a set time period, the communication interruption of the private line channel is indicated.
In this embodiment, the network channel monitoring module 20 is configured to monitor a network packet of a network channel of a substation, and determine a communication state of the network channel according to the network packet.
Different from monitoring the communication state of the private line channel through the communication frequency, the monitoring of the communication state of the network channel is judged through the network message transmitted by the network channel.
In one embodiment, the network channel monitoring module 20 may be connected to a switch, wherein the connection port of the network channel monitoring module 20 and the switch may be configured as a mirror port. When the method is implemented, the mirror port can be implemented by a port Mirroring (port Mirroring) method, wherein the port Mirroring method is implemented by forwarding data traffic of one or more source ports to a certain designated port on a switch or a router to monitor a network, the designated port is called a "mirror port" or a "destination port", and the network traffic can be monitored and analyzed through the mirror port under the condition that normal throughput of the source ports is not seriously affected, so that network data can be monitored and managed, and when a network fails, a fault can be quickly located.
The network channel monitoring module 20 is specifically configured to monitor the mirror flow of the mirror port, and when it is monitored that there is no message received or sent by the connection port, determine that the communication of the network channel is interrupted, and output a communication interruption signal to the fault processing module 30.
In a further embodiment, as shown in fig. 3, the switches in the substation may include a control area switch connected to the remote motors and a station level switch connected to one or more in-station measurement and control devices; as shown in fig. 2 or fig. 3, the network channel monitoring module 20 may include a first packet monitoring module and a second packet monitoring module. The first message monitoring module is connected with the control area switch and used for monitoring a first network message of a first network channel between the control area switch and the remote machine and determining the communication state of the remote machine according to the first network message; the second message monitoring module is connected with the station control layer switch and used for monitoring a second network message of a second network channel between the station control layer switch and one or more in-station measurement and control devices and determining the communication state of the one or more in-station measurement and control devices according to the second network message.
In this embodiment, the fault processing module 30 is configured to, when receiving a communication interrupt signal output by the dedicated line channel monitoring module 10 or the network channel monitoring module 20, determine a suspected faulty device on the dedicated line channel or the network channel, and perform fault processing on the suspected faulty device.
In one implementation, as shown in fig. 2, the fault handling module 30 may include an I/O interface, and the fault handling module 30 may receive a communication interruption signal from the dedicated channel monitoring module 10 or the network channel monitoring module 20 through the I/O interface.
Further, as shown in fig. 2, the fault handling module 30 may further include a controller, and the controller is configured to implement fault handling on the suspected fault device according to a set control logic. The failure recognition mode of the controller is also different for the dedicated line channel and the network channel.
In one embodiment, as shown in fig. 2 or fig. 3, the fault handling module 30 may include a first self-loop module and a second self-loop module for a scenario of a dedicated lane. As shown in fig. 3, the first self-loop module is disposed between the communication device and the modem, and the modem communicates with the scheduling master station via the communication device; the second self-loop module is arranged between the modem and the telecontrol machine. The first self-loop module and the second self-loop module are used for short-circuiting all groups of communication lines of the special line channel to form a self-loop circuit. For example, a first self-loop block may short T + and R + in the positive electrical path to form a self-loop and T-and R-in the negative electrical path to form a self-loop. Similarly, the second self-loop module can also short-circuit T + and R + in the positive electrical path to form a self-loop circuit, and short-circuit T-and R-in the negative electrical path to form a self-loop circuit.
When a suspected faulty device with a suspected fault is located, the fault processing module 30 is specifically configured to, when receiving a communication interrupt signal output by the dedicated line channel monitoring module 10, sequentially control the first self-loop module and the second self-loop module to act according to a set sequence, so as to identify that the suspected faulty device is a communication device, a modem, or a telemechanical device.
Specifically, when the fault processing module 30 receives the communication interrupt signal output by the dedicated line channel monitoring module 10, it is determined that the devices at the two ends of the dedicated line channel may have a fault, and then the two self-loop modules may be sequentially operated to identify a suspected faulty device.
For example, the first loopback module may be controlled to act first to establish a loopback loop between the communication device and the first loopback module, and if the communication of the dedicated line channel is not recovered at this time, it indicates that there is no problem in the in-station device, but the communication device (such as PCM, SDH, router, etc.) is suspected to have a failure; if the communication of the dedicated line channel is recovered (i.e. the communication interruption signal output by the dedicated line channel monitoring module 10 is not continuously received) at this time, it indicates that the communication equipment has not failed, and the failure may occur in the modem or the remote controller. To identify whether the modem is malfunctioning, the first self-loop module may be unlocked and the second self-loop module may be activated to establish a self-loop between the modem and the second self-loop module, indicating that the modem is not malfunctioning if the communication of the dedicated channel is restored at that time, the remote machine may be malfunctioning (i.e., the suspected malfunctioning device is a remote machine), and indicating that the modem is malfunctioning if the communication of the dedicated channel is not restored at that time (i.e., the suspected malfunctioning device is a modem).
For another example, the second self-loop module may be controlled to operate first to establish a self-loop between the modem and the second self-loop module, and if the communication of the dedicated channel is recovered (i.e. the communication interruption signal output by the dedicated channel monitoring module 10 is not continuously received) at this time, it indicates that the modem has not failed, and the failure may occur in a remote manner, that is, the suspected failed device is a remote manner; if the communication of the special line channel is not recovered at this time, the fault may occur in the connection between the communication device and the modem, in order to verify whether the fault occurs in the communication device or in the modem at all, the second self-loop module may be unlocked and the first self-loop module may be operated, if the communication of the special line channel is recovered at this time, it indicates that the communication device has no fault, the modem may have a fault, that is, the suspected faulty device is the modem; if the communication of the private line channel is not recovered at this time, it indicates that the communication device may be failed, that is, the suspected failed device is a communication device.
In another embodiment, for a scenario of a network channel, the fault handling module 30 is specifically configured to: when a communication interruption signal output by the first message monitoring module is received, the telecontrol machine is used as suspected fault equipment; when a communication interrupt signal output by the second message monitoring module is received, the in-station measurement and control equipment corresponding to the port outputting the interrupt signal is determined to be suspected fault equipment.
Specifically, when the fault processing module 30 receives the communication interruption signal output by the first message monitoring module, since the first message monitoring module monitors the communication message between the scheduling master station and the remote controller, it may be determined that the remote controller is suspected to have a fault after the communication message between the scheduling master station and the remote controller is interrupted, that is, the suspected fault device is the remote controller.
When the fault processing module 30 receives the communication interrupt signal output by the second message monitoring module, it is determined that the in-station measurement and control device corresponding to the port outputting the interrupt signal may have a fault, that is, the in-station measurement and control device corresponding to the port outputting the interrupt signal is a suspected fault device. When the method is realized, the port identification of the output interrupt signal can be searched in the MAC address table of the station control layer switch, and if the port identification is searched, the in-station measurement and control equipment corresponding to the searched MAC address is obtained and used as suspected fault equipment.
In one embodiment, the failure handling of the suspected failed device by failure handling module 30 may include a power outage restart. In implementation, as shown in fig. 2 and fig. 3, the failure processing module 30 may further include a power restart module, and after a suspected failed device is identified, the power restart module may be controlled to perform power-off restart on the suspected failed device.
In a further embodiment, the failure processing module 30 may further switch to a standby device, mainly for a case that the modem fails, and in implementation, the number of modems may include a plurality of modems, as shown in fig. 2 or fig. 3, and the failure processing module 30 may further include a modem switching module, and when the modem is powered off and restarted, the failure of the modem still exists (a communication interruption signal related to the device is still received), the modem switching module may be controlled to switch the failed modem to another standby modem, where switching of the modems may be performed according to a set sequence.
In the embodiment, the substation fault processing system can quickly locate the equipment with the communication fault in the substation and automatically process the fault, so that the recovery speed of the communication fault is improved, and manual operation of leaving the substation is reduced.
In an embodiment, as shown in fig. 2 or fig. 4, the substation fault processing system may further include a fault reporting module 40. In this embodiment, the fault processing module 30 is further configured to determine a suspected faulty device as a faulty device if it is determined that the fault of the suspected faulty device still exists after the fault processing, acquire device information of the faulty device, generate a fault notification according to the device information, and send the fault notification to the fault reporting module. The fault reporting module 40 is configured to send the fault notification to the scheduling master station, the scheduling master station positions the faulty equipment according to the received fault notification, and notifies relevant operation and maintenance personnel to perform fault processing, so that the relevant personnel can directly position the fault position accurately according to the equipment information, and notify the operation and maintenance personnel of the corresponding faulty equipment to eliminate the fault, for example, the operation and maintenance personnel can carry corresponding spare parts (such as new power equipment) to the substation to perform equipment replacement, thereby avoiding the relevant personnel from determining the faulty equipment in the substation repeatedly, and saving manpower and material resources.
In one implementation, the manner in which the fault reporting module 40 sends the fault notification to the scheduling master station may be: the fault reporting module 40 may output the fault notification to be sent to the master station to the accessed public measurement and control device, and the public measurement and control device sends the fault notification to the remote server in a remote signaling signal manner, and the remote server sends the fault notification to the master station.
In this embodiment, if the fault processing of the substation fault processing system is invalid, the faulty device information can be determined and the master station personnel can be notified, and the master station personnel can notify the relevant device operation and maintenance personnel to carry relevant spare parts to change the spare parts, so that the repeated work of the operation and maintenance personnel on entering the station is avoided.
