[0055] The following combination Figure 1-Figure 2 The present application is further described in detail, but the embodiments of the present invention are not limited thereto.

[0056] In the embodiments of the present application, a method and system for simulating faults in a power communication network are disclosed.

[0057] In this embodiment, a method for simulating a fault in a power communication network includes the following steps:

[0059] S200: Acquire historical fault data, simulate the occurrence of a fault on a virtual power communication network according to the historical fault data, and generate a simulated fault of the power communication network;

[0060] S300: determining a sending end and a receiving end of a virtual power communication network, generating a current signal at the sending end, and sending the current signal to the receiving end through the virtual power communication network;

[0061] S400: multiple signal nodes are set on the virtual power communication network. After the current signal passes through the signal node, the signal node adds a node identifier to the end of the current signal and sends a return current signal to the sending end;

[0062] S500: After receiving the current signal, the receiving end identifies the current signal to obtain an identification result, and combines the identification result and the returned current signal to obtain the fault location, fault type and fault cause.

[0063] It should be pointed out that the above steps are only a preferred implementation order. In the specific implementation process, some steps can be replaced without affecting the overall implementation effect.

[0064] The steps of obtaining construction data of the electric power communication network, generating a virtual map according to the construction data, and generating a virtual electric power communication network on the virtual map are specifically as follows:

[0065] Acquire the construction data of the electric power communication network, classify and integrate the construction data, and obtain the terrain data where the electric power communication network is located, the route design of the electric power communication network, and the facility layout;

[0066] Generate an initial virtual map based on terrain data, identify impacts on the initial virtual map, simplify the content that does not affect the power communication network, and obtain a virtual map;

[0067] A virtual power communication network is established in the virtual map based on the facility layout and route design.

[0068] In application, taking the electric power communication network in a certain city as an example, the construction data of the electric power communication network in the city is obtained, including the terrain data, route design and facility layout of the city and its surrounding areas during the construction process, and an initial virtual map is generated according to the terrain data of the city and its surrounding areas. The initial virtual map is a 3D map, which displays the terrain and landforms of the city and its surrounding areas from a 3D perspective. A virtual electric power communication network is established on the initial virtual map according to the route design and facility layout, and then the content in the initial virtual map that is irrelevant to or has little impact on the electric power virtual electric power communication network is simplified or blanked to reduce memory consumption and obtain a virtual map.

[0069] The steps of obtaining historical fault data, simulating the occurrence of faults on a virtual power communication network according to the historical fault data, and generating simulated faults of the power communication network are specifically as follows:

[0070] Obtain historical fault data, and obtain historical fault phenomena, historical fault causes, historical fault locations, and historical fault environments based on the historical fault data;

[0071] Obtain the fault simulation requirements of the current power communication network, adjust the historical fault phenomena, historical fault causes, historical fault locations, and historical fault environments according to the fault simulation requirements, and obtain the target phenomena, target causes, target locations, and target environments respectively;

[0072] generating simulated faults on a virtual power communication network according to a target phenomenon, a target cause, a target location, and a target environment;

[0073] The simulated fault is reproduced on the virtual power communication network to generate a simulated fault of the power communication network.

[0074] In application, taking the electric power communication network in a certain city as an example, the background data of the electric power communication network in the city is collected to obtain the historical fault data of the electric power communication network in the city, that is, the fault data that has occurred in the electric power communication network in the city in history. According to the historical fault data, a typical fault is selected as an example. For example, there is a problem with the transmission quality at a certain location. The historical fault data of the typical fault is processed to obtain the historical fault phenomenon, historical fault cause, historical fault location and historical fault environment of the typical fault, and then the simulation requirements of the current electric power communication network failure are obtained. The simulation requirements of this time are insufficient network stability and transmission quality problems. The fault simulation requirements of insufficient network stability are substituted into the above four contents to obtain the target phenomenon, target cause, target location and target fault environment required for this simulated fault. Then, a simulated fault is generated on the virtual electric power communication network according to the above contents, and reproduced on the virtual electric power communication network.

[0075] The steps of determining a sending end and a receiving end of a virtual power communication network, generating a current signal at the sending end, and sending the current signal to the receiving end through the virtual power communication network are specifically:

[0076] Based on the virtual power communication network, determining the sending end and the receiving end of the virtual power communication network, and obtaining the sending position and the receiving position;

[0077] Extracting a partial network of the virtual power communication network between the sending location and the receiving location, and obtaining a plurality of communication lines from the sending end to the receiving end according to the partial network;

[0078] generating a current signal at a transmitting end, and determining a current length, an electromagnetic frequency, and a voltage waveform of the current signal;

[0079] A current signal is sent from the transmitting end to the receiving end through each communication line.

[0080] In application, taking the power communication network in a certain city as an example, in the virtual power communication network of this city, the sending end is determined to be located at the easternmost end of the city, and the receiving end is at the westernmost end of the city. After the sending end and the receiving end are connected, they cover the virtual power communication network of the entire city. Then, based on the virtual power communication network of the city, 8 communication lines from the sending end to the receiving end are generated. These 8 communication lines cover each network segment of the virtual power communication network of the entire city. A current signal is generated at the sending end, and the current signal is sent to the receiving end through these 8 communication lines respectively, and the generated current signal has a fixed current length, electromagnetic frequency and voltage waveform.

[0081] A plurality of signal nodes are set on the virtual power communication network. After the current signal passes through the signal node, the signal node adds a node identifier to the end of the current signal and sends a return current signal to the sending end. Specifically, the steps are as follows:

[0082] Setting a plurality of signal nodes on a portion of the virtual power communication network according to the communication lines;

[0083] When the current signal passes through the signal node, the signal node intercepts the current signal, adds the node signal to the end of the current signal to generate a new current signal, and forwards the new current signal to the next signal node;

[0084] After the current signal passes through the signal node, the signal node identifies the current signal and obtains the length data, frequency data and waveform data of the current signal;

[0085] A return data packet is generated by combining the length data, the frequency data and the waveform data, a return current signal is generated according to the return data packet, and the return current signal is sent to the sending end.

[0086] In application, taking the power communication network in a certain city as an example, multiple signal nodes are set on the virtual power communication network of the city. When the current signal sent by the sending end passes through the signal node, the current signal is identified. For example, in a communication line with a fault, when the current signal reaches a signal node after passing the fault point, the signal node identifies the current signal length data, frequency data and waveform data. If the frequency data and waveform data are changed, these changed data are recorded, and then the node signal of this signal node is added to the end of the current signal to generate a new current signal. The new current signal is then sent along the communication line. At the same time, the recorded changed frequency data and waveform data are integrated to generate a return current signal and sent back to the sending end.

[0087] After the steps of setting a plurality of signal nodes on the virtual power communication network, and after the current signal passes through the signal node, the signal node adds a node identifier to the end of the current signal, and sends a return current signal to the sending end, the method further includes:

[0088] According to the collected multiple return current signals, the length data, frequency data and waveform data in the return current signal are compared with the current length, electromagnetic frequency and voltage waveform to obtain the length change, frequency change and waveform change;

[0089] Extract the change amount of length change, frequency change and waveform change, and determine whether the change amount is greater than or equal to a preset change amount threshold;

[0090] If it is determined that the change is greater than or equal to the change threshold, it indicates that the communication line corresponding to the change is faulty, a first faulty line is obtained, and the length change, frequency change, and waveform change are packaged to generate a first faulty data packet;

[0091] Counting the return current signal and confirming the node position, to obtain the signal quantity and node position of the return current signal;

[0092] Determine whether the number of signals is lower than the total number of preset signal nodes. If it is determined that the number of signals is lower than the total number of preset signal nodes, obtain the lost node without returning signal according to the node position;

[0093] Determine a second fault line having a fault according to the lost node, and extract node data of the lost node to generate a second fault data packet;

[0094] The first fault data packet and the second fault data packet are integrated to generate a fault data packet, and the fault data packet is sent to the receiving end.

[0095] In use, taking the power communication network in a certain city as an example, after receiving the returned current signal, the sending end processes the data in the returned current signal to obtain the frequency change and waveform change in the current signal, and finds that the change amount of the frequency change and the waveform change is greater than the preset change amount threshold, then it is judged that there is a fault on the communication line corresponding to the received returned current signal, and the fault position is determined according to the node position of the signal node corresponding to the returned current signal, and it can be determined that the fault of the communication line only affects the communication efficiency or communication quality, etc., and the first fault data packet is generated according to the above content. Then the returned current signal is counted, and the node position of each returned current signal is determined, and then the signal node corresponding to each node position is compared with all signal nodes. It is found that there are 3 signal nodes on a certain communication line without a returned current signal, then it can be determined that the communication line is broken, and then these 3 signal nodes are marked as lost nodes, the node data of the lost nodes are extracted and the second fault data packet is generated, and the first fault data packet and the second fault data packet are integrated to generate the fault data packet of the entire virtual power communication network, and the fault data packet is sent to the receiving end along the intact communication line.

[0096] After receiving the current signal, the receiving end identifies the current signal to obtain an identification result, and combines the identification result and the returned current signal to obtain the fault location, fault type and fault cause. Specifically, the steps are as follows:

[0097] According to the return current signal, the fault data packet received by the receiving end is obtained, and the target fault line is determined according to the fault data packet;

[0098] Obtain environmental data within the range of the target fault line according to the target fault line, and obtain electromagnetic influence of the environment on the current signal according to the environmental data;

[0099] Performing signal correction on the current signal based on electromagnetic influence to obtain a target current signal, and performing spectrum analysis on the target current signal to obtain spectrum data of the target current signal;

[0100] Performing standardized signal recognition on the current signal according to the spectrum data to obtain a recognition result of the current signal;

[0101] The fault location, fault type and fault cause are obtained by combining the identification result and the first fault data packet and / or the second fault data packet corresponding to the target fault line.

[0102] In application, taking the electric power communication network in a certain city as an example, the receiving end obtains a fault data packet based on the received return current signal. The fault data packet gives a target fault line where the fault occurs. Environmental data within the range of the target fault line are collected to obtain that the environment within the range of the target fault line is thunderstorm weather. Further, the electromagnetic influence of the thunderstorm on the current signal in the target fault line is obtained. The electromagnetic influence will cause the electromagnetic frequency and voltage waveform in the current signal to change. According to the electromagnetic influence, the electromagnetic frequency and voltage waveform are corrected to obtain the target current signal, that is, the current signal not affected by the electromagnetic influence. The frequency data of the target current signal is obtained after frequency analysis of the target current signal. Standardized signal recognition is performed based on the frequency data to obtain an identification result. According to the obtained identification result, the fault location, fault type and fault cause of the simulated fault are obtained in combination with the first fault data packet and / or the second fault data packet. The fault causes include sudden changes in voltage and current in the electric power communication network, and an increase or decrease in electromagnetic frequency caused by thunderstorm weather.
