The application environment comprises a power transmission network comprising a monitoring device 101, the power transmission network further comprising a plurality of transmission paths, each transmission path comprising a voltage step-up device 102, a high voltage transmission device 103 and a voltage step-down device 104. The power transmission network may also include power generation equipment 105, low voltage distribution equipment 106, and consumer equipment 107. The voltage output by the power generation device 105 is boosted by the voltage boosting device 102, the boosted high voltage is transmitted to the voltage reduction device 104 through the high voltage transmission device 103, and the high voltage is reduced by the voltage reduction device 104. The voltage step-down device then transmits the reduced voltage to the low voltage distribution device 106, and the low voltage distribution device 106 distributes the voltage to the electric devices 107. The monitoring device 101 may communicate with a powered device,

In one embodiment, as shown in fig. 2, a fault detection method for a power transmission network is provided, which is described by taking the method as an example applied to the monitoring device in fig. 1, and includes the following steps:
The detection instruction is used for instructing the target boosting equipment to output a detection voltage; the detection voltage is transmitted to the target high-voltage transmission device and the target step-down device in the target transmission path.
The device inventory may include device identifications of a plurality of voltage boost devices, device identifications of high voltage transmission devices, and device identifications of voltage buck devices. In the fault detection process, the monitoring equipment determines a target transmission path to be detected according to the equipment identifier in the equipment list.
For example, the monitoring device selects the boosting device A1 according to the device identifier in the device list, and determines the transmission path where the boosting device A1 is located as a target transmission path to be detected; after the detection of the transmission path where the boosting device A1 is located is completed, the monitoring device selects the boosting device A2 according to the device identifier in the device list, and determines the transmission path where the boosting device A2 is located as a target transmission path to be detected. And by analogy, all transmission paths in the power transmission network are sequentially determined as target transmission paths.
And after determining the target transmission path, the monitoring equipment sends a detection instruction to the target boosting equipment in the target transmission path. The target boosting device is provided with an energy storage component, and after receiving a detection instruction, the energy storage component provides detection voltage. After the target voltage boosting device outputs the detection voltage, the detection voltage is sequentially transmitted to the target high-voltage transmission device and the target voltage reduction device in the target transmission path.
In one embodiment, the detection voltage may be 36V.
If the line between the target boosting equipment and the target high-voltage transmission equipment is normal, and the detection voltage is transmitted from the target boosting equipment to the target high-voltage transmission equipment, the target high-voltage transmission equipment responds to the detection voltage to obtain a positive response result; if the line between the target boosting equipment and the target high-voltage transmission equipment is abnormal, the detection voltage cannot be transmitted to the target high-voltage transmission equipment, and the target high-voltage transmission equipment cannot respond to the detection voltage to obtain a negative response result.
After the detection voltage is transmitted to the target high-voltage transmission equipment, if a line between the target high-voltage transmission equipment and the target voltage reduction equipment is normal, the detection voltage is transmitted from the high-voltage transmission equipment to the target voltage reduction equipment, and the target voltage reduction equipment responds to the detection voltage to obtain a positive response result; and if the line between the target high-voltage transmission equipment and the target voltage reduction equipment is abnormal, the target voltage reduction equipment does not respond to the detection voltage, and a negative response result is obtained.
And the fault detection result is used for indicating whether the target transmission path has a fault or not. The fault may include at least one of leakage of electricity, foreign objects on the line affecting the voltage and damage to the line.
The monitoring device may determine whether a line between the target voltage boosting device and the target high voltage transmission device have a fault according to a response result of the target high voltage transmission device to the detection voltage. The monitoring device can also determine whether a line between the target high-voltage transmission device and the target voltage reduction device have faults or not according to the response result of the target voltage reduction device to the detection voltage.
In the fault detection method of the power transmission network, the monitoring equipment determines a target transmission path to be detected according to a preset equipment list and sends a detection instruction to target boosting equipment in the target transmission path; then, respectively obtaining the response results of the target high-voltage transmission equipment and the target voltage reduction equipment to the detection voltage; and finally, determining a fault detection result of the target transmission path according to the response result. In the embodiment of the disclosure, the monitoring device may determine whether the target transmission path has a fault by detecting a transmission condition of the voltage on the target transmission path and a response condition of each device to the detected voltage. Therefore, even if the transmission route in the power transmission network is complex, the fault detection of the power transmission network can be well completed, and the maintenance cost is reduced.
In one embodiment, as shown in fig. 3, on the basis of the above embodiment, the embodiment of the present disclosure may further include:
The power transmission network may also include feedback devices. After the monitoring device determines a target transmission path according to the device list, the detection instruction is firstly sent to the feedback device, and then the feedback device sends the detection instruction to the target boosting device in the target transmission path.
The target voltage boosting device receives the detection instruction and outputs a detection voltage. The detection voltage is transmitted to the high-voltage transmission device and the step-down device in the target transmission path.
In practical applications, the feedback module may also communicate with the target voltage reduction device to send some instructions output by the monitoring device to the target voltage reduction device.
And the first response result and the second response result are acquired by the data acquisition equipment from the target high-voltage transmission equipment and the target voltage reduction equipment and are sent to the information collection equipment.
The power transmission network can further comprise data acquisition equipment, and the data acquisition equipment acquires data of the equipment. For example, the power transmission network includes a target high-voltage transmission device B1, a target step-down device C1, and a data collection device D1, wherein the data collection device D1 collects a first response result of the target high-voltage transmission device B1 to the detection voltage and a second response result of the target step-down device C1 to the detection voltage.
And the data acquisition equipment acquires a first response result from the target high-voltage transmission equipment and transmits the first response result and a second response result to the information collection equipment after acquiring a second response result from the target voltage reduction equipment.
In practical application, the data collection device can actively collect data, and the information collection device passively receives data and collects the received data.
And step 303, if the first response result is determined to be inconsistent with the historical response record of the target high-voltage transmission equipment, determining that the fault detection result comprises that the target high-voltage transmission equipment has a fault.
The monitoring device stores a historical response record of the target high-voltage transmission device in advance, and if the first response result of the target high-voltage transmission device responding to the detection voltage is determined to be inconsistent with the historical response record, the current state of the target high-voltage transmission device is not a normal state, so that the target high-voltage transmission device can be determined to have a fault.
And 304, if the second response result is determined to be inconsistent with the historical response record of the target voltage reduction device, determining that the fault detection result comprises that the target voltage reduction device has a fault.
The monitoring device stores a historical response record of the target voltage reduction device in advance, and if it is determined that a first response result of the target voltage reduction device responding to the detected voltage at present is inconsistent with the historical response record, it is indicated that the current state of the target voltage reduction device is not a normal state, so that the target voltage reduction device can be determined to have a fault.
In the above embodiment, the monitoring device determines the target transmission path to be detected according to a preset device list, outputs the detection instruction to the feedback device, and the feedback device forwards the detection instruction to the target voltage boosting device. Then, the monitoring equipment respectively acquires a first response result of the target high-voltage transmission equipment to the detection voltage and a second response result of the target voltage reduction equipment to the detection voltage from the information collection equipment, and determines whether the target high-voltage transmission equipment has a fault according to whether the first response result is consistent with a historical response record of the target high-voltage transmission equipment; and determining whether the target voltage reduction device has a fault according to whether the second response result is consistent with the historical response record of the target voltage reduction device. Through the embodiment of the disclosure, the monitoring equipment judges whether the fault exists according to the response result and the historical response record, and the fault detection speed can be increased, so that the fault equipment can be maintained quickly.
In one embodiment, the power transmission network may be outage detected by disconnecting the power transmission network from the low voltage distribution equipment and then disconnecting the voltage boost device from the power generation equipment to power down the voltage boost device, the high voltage transmission equipment, and the voltage step down device to form a safe area. After the power failure, the voltage boosting equipment, the high-voltage transmission equipment and the voltage reduction equipment can detect that the voltage is greatly reduced, self-checking is carried out at the moment, and a self-checking result is output after the self-checking. The self-checking result may include a fault code, among others.
The data acquisition equipment actively collects self-checking results output by each equipment. An equipment list can be preset in the data acquisition equipment, and the data acquisition equipment determines whether equipment which does not send the self-checking result exists according to the equipment list. And if the equipment which does not send the self-checking result exists, the data acquisition equipment sends a data acquisition instruction to the equipment, and the data acquisition instruction instructs the equipment to carry out self-checking and send the self-checking result.
Wherein, the device list may be as shown in table 1:
TABLE 1
The self-test results can be shown in table 2:
TABLE 2
The data acquisition equipment acquires the self-checking result of each equipment, and can adopt the data acquisition instruction with the following format: 1) The interface of the Internet of things adopts an MAC address to issue, and the format is as follows: device name + MAC address + device command; 2) The network interface issues through the IP address, and the format is as follows: device name + IP address + device command.
The embodiment of the disclosure does not limit the equipment list format, the self-checking result format and the data acquisition instruction format.
And the data acquisition equipment sends the self-checking result to the information collection equipment according to the warning level in the self-checking result. For example, if the alarm level is severe in the self-test result, the self-test result is transmitted to the information collection device immediately after the self-test result is received. If the alarm level in the self-checking result is warning, after the self-checking results of all the equipment in the equipment list are received, the self-checking results with the alarm level as warning are packaged and uniformly sent. The alarm level is not limited in the embodiments of the present disclosure.
The data acquisition equipment can also store the self-checking result of each equipment according to the time stamp so as to be convenient for later retrieval and analysis.
After the data collection entity sends the self-test result to the information collection device, the monitoring device may perform the steps shown in fig. 4:
The alarm information is acquired by the data acquisition equipment from each boosting equipment, each high-voltage transmission equipment and each voltage reduction equipment in the power failure detection process and is sent to the information collection equipment.
In the power failure detection process, the data acquisition equipment acquires alarm information from each of the boosting equipment, the high-voltage transmission equipment and the voltage reduction equipment, and then sends the alarm information to the information collection equipment. And then, the information collection equipment sends alarm information to the monitoring equipment, and correspondingly, the monitoring equipment receives the alarm information sent by the information collection equipment.
And step 402, executing corresponding processing according to the alarm information.
The monitoring equipment can adopt different processing modes according to different alarm information. One way is to upload the alarm information to the power station server. For example, if the alarm level is serious, the monitoring device sends the alarm information to the power station server immediately after receiving the alarm information, and the power station server generates prompt information after receiving the alarm information to notify maintenance personnel of performing maintenance in time. For another example, if the number of times of alarm exceeds a preset number of times or the alarm information includes a keyword, the alarm information is uploaded to the power station server according to preset uploading time. The uploading timing is not limited in the embodiments of the present disclosure.
Another way is to send the fixed operation indicated by the alarm information to the device corresponding to the alarm information. The monitoring equipment can preset the corresponding relation between the alarm information and the fixed operation, after receiving the alarm information, the monitoring equipment can determine whether the alarm information has the corresponding fixed operation according to the corresponding relation, and if the alarm information has the corresponding fixed operation, the monitoring equipment sends the fixed operation to the equipment corresponding to the alarm information.
The process of sending the fixed operation to the device corresponding to the warning information may include: and sending the fixed operation to the feedback equipment, and sending the fixed operation to equipment corresponding to the warning information by the feedback equipment.
For example, if the device corresponding to the alarm information is the voltage boosting device A1, the feedback device sends a fixed operation to the voltage boosting device A1, and the voltage boosting device A1 performs the fixed operation.
In the above embodiment, the power failure detection is performed on the power transmission network, the data acquisition device acquires the self-check results of each device, and then the data acquisition device sends the self-check results to the information collection device in due time according to the alarm level in the self-check results. The monitoring equipment receives alarm information sent by the information collecting equipment; and executing corresponding processing according to the alarm information. Through the embodiment of the disclosure, the power failure detection of the power transmission network can be realized, the monitoring equipment can transmit the alarm information to the power station server in time, notify maintenance personnel to maintain in time, and also can instruct the equipment corresponding to the alarm information to execute fixed operation, thereby maintaining the safe and stable operation of the power transmission network.
Except for the power-off detection, if abnormality occurs in the working process of each device, abnormal information is sent to the data acquisition device. And after the data acquisition equipment acquires the abnormal information, the abnormal information is sent to the information collection equipment. Thereafter, the monitoring device may perform the steps as shown in fig. 5:
And the abnormal information is sent to the data acquisition equipment when the equipment is abnormal, and is forwarded to the information collection equipment by the data acquisition equipment.
After the information collection device collects the abnormal information, the abnormal information is sent to the monitoring device, and correspondingly, the monitoring device receives the abnormal information sent by the information collection device.
And 502, executing corresponding processing according to the abnormal information.
After receiving the abnormal information, the monitoring device may upload the abnormal information to the power station server, or may send the fixed operation indicated by the abnormal information to the device corresponding to the abnormal information.
