Abstract
Description
Technical Field
[0001] This application relates to the field of power system security protection technology, specifically to an automated protection device for power systems. Background Technology
[0002] A power system is a complex network system specifically designed for transmitting and distributing electrical resources. Its stable operation is crucial for ensuring the normal power supply for social production and daily life. When abnormal conditions occur in the power system, such as voltage fluctuations, current overloads, or short circuits, the normal transmission and distribution of electrical resources will be directly affected, potentially causing damage to electrical equipment or even system collapse. To address such problems, widely adopted power system protection technologies typically integrate various protection modules, such as circuit breakers, relays, and intelligent protection devices. These modules can quickly disconnect the system circuit upon detecting anomalies, thereby preventing the fault from escalating further.
[0003] However, while existing protection technologies can achieve rapid power outages and effectively avoid the direct harm caused by instantaneous overloads or short circuits, they have a significant limitation: they cannot automatically diagnose or analyze the root cause of power system anomalies. This protection method is essentially a "stopgap measure," addressing only the surface problem without deeply identifying and resolving the fault source. Especially for inexperienced system maintenance personnel, it is often difficult to efficiently and accurately determine the cause of the anomaly based on the triggered protection mechanisms. Reclosing the circuit and restoring power supply without identifying and addressing the cause can easily lead to the same anomaly recurring, repeatedly triggering the protection mechanisms and causing frequent power system interruptions.
[0004] Such frequent switching not only accelerates the aging or damage of electrical equipment due to repeated current surges, but also seriously affects the normal operation of the equipment. Therefore, while current power system protection methods ensure short-term system safety, they also expose their shortcomings in fault cause identification and long-term reliability. Summary of the Invention
[0005] The purpose of this application is to overcome the shortcomings and deficiencies of the prior art and provide an automated protection device for power systems.
[0006] A first aspect of this application provides an automated protection device for power systems, comprising:

The step-down power supply unit is used to step down the working voltage output by the target power system and then output it to the system data acquisition unit and the data upload unit through the first output terminal and the second output terminal, respectively.
[0019] In one implementation, the anomaly detection module includes a network communication unit and an anomaly detection unit;
[0020] The network communication unit is used to receive the operating data uploaded by the power system monitoring module and transmit the operating data to the anomaly detection unit;
[0021] The anomaly detection unit is used to input the received operating data into the trained power system anomaly detection model when no operating data is received for more than a first preset time, to obtain the first anomaly detection result and transmit it to the network communication unit. The network communication unit then sends the first anomaly detection result to the terminal device designated by the system maintenance personnel.
[0022] As one implementation method, the power system anomaly detection model has a deep learning network model structure.
[0023] In one implementation, the protection device further includes a power system simulation module, and the anomaly detection module is communicatively connected to the power system simulation module;

[0025] The power system simulation module accelerates the simulation of the restart operation state of the target power system based on the maintenance information and the operation data; if the accelerated simulation of the restart operation state is normal within a second preset time period, the power system simulation module issues a conduction permission to the anomaly detection module.
[0026] The anomaly detection module forwards the conduction permission to the power system protection module, enabling the power system protection module to conduct the system circuit of the target power system.

[0031] As one implementation method, if an abnormal state occurs in the restart operation state of the accelerated simulation within the second preset time period, the power system simulation module transmits the accelerated simulation data to the abnormality detection module.
[0032] The anomaly detection module performs anomaly prediction on the target power system again based on the accelerated simulation data, and sends the second anomaly detection result to the terminal device designated by the system maintenance personnel, so that the system maintenance personnel can perform maintenance and repair on the target power system based on the second anomaly detection result.

The anomaly detection module is used to receive the operational data uploaded by the power system monitoring module, predict anomalies in the target power system based on the operational data, and send a first anomaly detection result to a terminal device designated by system maintenance personnel. This allows system maintenance personnel to perform maintenance and repair on the target power system based on the first anomaly detection result. This method can efficiently and accurately obtain the first anomaly detection result triggered by the power system protection module, facilitating maintenance and repair of the target power system. This improves the efficiency and accuracy of maintenance and repair of the target power system and prevents repeated triggering of the protection mechanism due to the same anomaly, avoiding frequent power outages and ensuring the normal operation of the target power system and the normal use of electrical equipment.

[0043] Please see Figure 1 This is a schematic diagram of the module connection of an automated protection device 100 for a power system according to the first embodiment of this application. The protection device includes:
[0044] A power system protection module 101 is electrically connected to a target power system. The power system protection module 101 is used to cut off the system circuit of the target power system when a power abnormality occurs in the target power system.
[0045] A power system monitoring module 102 is electrically connected to the target power system. The target power system provides operating power to the power system monitoring module 102. The power system monitoring module 102 is used to collect and upload the operating data of the target power system.
[0046] An anomaly detection module 103 is communicatively connected to the power system monitoring module 102. The anomaly detection module 103 is used to receive the operating data uploaded by the power system monitoring module 102, predict the anomalies of the target power system based on the operating data, and send the first anomaly detection result to the terminal device designated by the system maintenance personnel so that the system maintenance personnel can perform maintenance and repair on the target power system based on the first anomaly detection result.
[0047] Compared with related technologies, the automated protection device 100 for power systems in this application includes a power system protection module 101 and a power system monitoring module 102 electrically connected to the target power system, and an anomaly detection module 103 communicatively connected to the power system monitoring module 102. The power system protection module 101 is used to disconnect the system circuit of the target power system when a power anomaly occurs. The power system monitoring module 102 is used to collect and upload the operating data of the target power system. The anomaly detection module 103 is used to receive the operating data uploaded by the power system monitoring module 102, predict the anomaly of the target power system based on the operating data, and send the first anomaly detection result to the terminal device designated by the system maintenance personnel. This allows the system maintenance personnel to maintain and repair the target power system based on the first anomaly detection result. The module can efficiently and accurately obtain the first anomaly detection result of the target power system triggering the power system protection module 101, so that the system maintenance personnel can maintain and repair the target power system based on the first anomaly detection result. This improves the efficiency and accuracy of the maintenance and repair of the target power system, and can prevent the same anomaly from recurring and causing repeated triggering of the protection mechanism, avoiding frequent switching of the target power system, which is conducive to the normal operation of the target power system and the normal use of electrical equipment.
[0048] In one feasible embodiment, the power system protection module 101 includes a current protection unit electrically connected to the target power system;
[0049] The current protection unit is used to disconnect the system circuit of the target power system when a short circuit or overload occurs in the target power system, causing the current to exceed a preset current value.
[0050] In one feasible embodiment, the power system protection module 101 includes a voltage protection unit, which is electrically connected to the target power system;
[0051] The voltage protection unit is used to disconnect the system circuit of the target power system when the system voltage of the target power system exceeds a preset voltage value.
[0052] In one feasible embodiment, the power system monitoring module 102 includes a system data acquisition unit and a data upload unit; wherein, the target power system provides operating power to the system data acquisition unit and the data upload unit;
[0053] The system data acquisition unit is used to collect the operating data of the target power system and transmit the operating data to the data upload unit;
[0054] The data upload unit is used to upload the running data to the anomaly detection module 103.
[0055] In one feasible embodiment, the power system monitoring module 102 further includes a step-down power supply unit; the step-down power supply unit includes a power input terminal, a first output terminal, and a second output terminal;
[0056] The power input terminal of the step-down power supply unit is connected to the target power system, the first output terminal of the step-down power supply unit is connected to the system data acquisition unit, and the second output terminal of the step-down power supply unit is connected to the data upload unit. The step-down power supply unit is used to step down the working voltage output by the target power system and then output it to the system data acquisition unit and the data upload unit through the first output terminal and the second output terminal, respectively.
[0057] In one feasible embodiment, the anomaly detection module 103 includes a network communication unit and an anomaly detection unit;
[0058] The network communication unit is used to receive the operating data uploaded by the power system monitoring module 102 and transmit the operating data to the anomaly detection unit;
[0059] The anomaly detection unit is used to input the received operating data into the trained power system anomaly detection model when no operating data is received for more than a first preset time, to obtain the first anomaly detection result and transmit it to the network communication unit. The network communication unit then sends the first anomaly detection result to the terminal device designated by the system maintenance personnel.
[0060] The network communication unit and the anomaly detection unit are located on a cloud server. The first preset duration is set by the user, for example, it can be set to 3 seconds, 5 seconds, 6 seconds, 8 seconds, 10 seconds, etc.
[0061] In this embodiment, when the target power system is normally connected, it provides power to the power system monitoring module 102, so the power system monitoring module 102 can normally collect the operating data and upload it to the anomaly detection module 103. When the target power system is abnormal, the power system protection module 101 disconnects the system circuit of the target power system, and the target power system cannot provide power to the power system monitoring module 102. At this time, the power system monitoring module 102 stops collecting and uploading the operating data. When the anomaly detection unit of the anomaly detection module 103 does not receive the operating data for more than a first preset time, it determines that the target power system is disconnected from the system circuit due to an anomaly. At this time, the anomaly detection module 103 inputs the received operating data into the trained power system anomaly detection model to obtain the first anomaly detection result based on the operating data. Since the network communication unit and the anomaly detection unit are located on a cloud server and are not powered by the target power system, they can still operate normally even if the target power system is disconnected, so as to obtain the first anomaly detection result and send it to the terminal device.
[0062] Since anomalies in the target power system are primarily reflected in the operational data prior to the disconnection, the anomaly detection module 103 only inputs the latest operational data received within a preset detection period into the trained power system anomaly detection model. This facilitates the acquisition of a first anomaly detection result based on the latest received operational data. For example, by using the timestamp of the latest received operational data and the preset detection period, the starting timestamp of the data input into the power system anomaly detection model is derived in reverse. The data between the starting timestamp and the timestamp of the latest operational data is then input into the power system anomaly detection model for anomaly detection. This controls the amount of data processed for anomaly detection, improves data efficiency, and allows for the rapid and accurate acquisition of the first anomaly detection result. The preset detection period is user-defined and can be set to 5 minutes, 10 minutes, 15 minutes, 20 minutes, 30 minutes, etc.
[0063] In one feasible embodiment, the power system anomaly detection model is structured as a deep learning network model.
[0064] The power system anomaly detection model can be trained using anomaly detection training samples of the target power system. These training samples include positive and negative samples. The positive samples correspond to the operating data samples of the target power system during normal operation, while the negative samples correspond to the operating data samples of the target power system that are disconnected due to an anomaly, specifically the operating data samples of the target power system before the disconnection.
[0065] Please see Figure 2 In one feasible embodiment, the protection device further includes a power system simulation module 104, and the anomaly detection module 103 is communicatively connected to the power system simulation module 104;
[0066] The anomaly detection module 103 is also used to receive maintenance processing information uploaded by the terminal device, and transmit the maintenance processing information and the operation data to the power system simulation module 104;
[0067] The power system simulation module 104 accelerates the simulation of the restart operation state of the target power system based on the maintenance processing information and the operation data; if the accelerated simulation of the restart operation state is normal within a second preset time period, the power system simulation module 104 issues a conduction permission to the anomaly detection module 103.
[0068] The anomaly detection module 103 forwards the conduction permission to the power system protection module 101, so that the power system protection module 101 conducts the system circuit of the target power system.
[0069] Wherein, the second preset duration is greater than the preset detection duration, or the second preset duration is greater than the data duration of the running data stored in the preset storage space. Preferably, the second preset duration is at least three times the preset detection duration.
[0070] Accelerated simulation is a method of simulating the restart operation status of the target power system over a long period of time based on the maintenance information and the operating data. For example, by simulating over a time period, the operating status of the target power system in multiple future time periods after restart can be obtained.
[0071] The maintenance information includes the maintenance object and its corresponding maintenance parameters. During the simulation, the maintenance parameters of the maintenance object affect both the maintenance object and the system components following it; however, the system components preceding the maintenance object and those not related to it are unaffected. Therefore, the simulation can be performed based on the operating data of the system components preceding the maintenance object, the operating data of those not related to it, and the maintenance parameters of the maintenance object. The system components preceding, following, and not related to the maintenance object can all be obtained based on the system operation logic of the target power system. For example, within the same system branch, the upper part is divided into the lower part of the system component before the branch; different system branches belong to system components that are not related to each other.
[0072] In this embodiment, the anomaly detection module 103 needs to grant the power system simulation module 104 the power system protection module 101 the power system circuit to conduct the target power system circuit. This prevents the target power system circuit from being arbitrarily conducted without completing the restart simulation, thus preventing the same anomaly from recurring and triggering the protection mechanism repeatedly. This avoids frequent switching of the target power system, which is beneficial to the normal operation of the target power system and the normal use of electrical equipment.
[0073] Please see Figure 3 In one feasible embodiment, the protection device further includes a power system simulation module 104, and the anomaly detection module 103 is communicatively connected to the power system simulation module 104;
[0074] The anomaly detection module 103 is also used to receive maintenance processing information uploaded by the terminal device, and transmit the maintenance processing information and the operation data to the power system simulation module 104;
[0075] The power system simulation module 104 accelerates the simulation of the restart operation state of the target power system based on the maintenance processing information and the operation data; if the accelerated simulation of the restart operation state is normal within a second preset time period, the power system simulation module 104 issues a conduction permission to the anomaly detection module 103.
[0076] The anomaly detection module 103 forwards the conduction permission to the terminal device, so that the terminal device controls the power system protection module 101 to conduct the system circuit of the target power system according to the conduction permission.
[0077] In this embodiment, the terminal device needs to control the power system protection module 101 to connect the system circuit of the target power system only according to the connection permission issued by the power system simulation module 104. This avoids arbitrarily connecting the system circuit of the target power system without completing the restart simulation, and prevents the same abnormality from recurring and triggering the protection mechanism repeatedly. This avoids frequent switching of the target power system, which is conducive to the normal operation of the target power system and the normal use of electrical equipment.
[0078] In a feasible embodiment, if the restart operation state of the accelerated simulation becomes abnormal within the second preset time period, the power system simulation module 104 transmits the accelerated simulation data to the abnormality detection module 103.
[0079] The anomaly detection module 103 performs anomaly prediction on the target power system again based on the accelerated simulation data, and sends the second anomaly detection result to the terminal device designated by the system maintenance personnel, so that the system maintenance personnel can perform maintenance and repair on the target power system based on the second anomaly detection result.
[0080] In this embodiment, if the accelerated simulation restart operation status becomes abnormal within the second preset time period, it indicates that the maintenance processing content of the maintenance processing information is incorrect, resulting in the continued existence of abnormal factors or the occurrence of other abnormal factors. It is even possible that other abnormal factors still exist in the target power system. Therefore, the anomaly detection module 103 needs to perform anomaly detection again based on the accelerated simulation data of the power system simulation module 104, so as to send a new second anomaly detection result to the terminal device designated by the system maintenance personnel. This allows the system maintenance personnel to continue to maintain and repair the target power system, preventing the protection mechanism from being triggered again after the target circuit system is turned on, avoiding frequent on / off switching of the target power system, which is conducive to the normal operation of the target power system and the normal use of electrical equipment.
