Description

Technical Field

[0001] The present application relates to the field of power monitoring, and in particular to a substation monitoring method, device, equipment, storage medium and computer program product. Background Art

[0002] Substations are power facilities that transform voltage, receive and distribute electric energy, control the flow of electricity and adjust voltage in power systems. Substations usually convert high-voltage currents transmitted by transmission lines into low-voltage electric energy through transformers and other equipment, so that the electric energy can be distributed to residential areas, industrial areas and other power-consuming areas.

[0003] Given the importance of substations in the power supply process, it is necessary to monitor the safety of the substation working environment to ensure the stable operation of the power system. At present, monitoring of substation safety usually includes: setting up a variety of sensors (such as temperature and humidity, infrared, smoke, etc.) in the area where the substation is located to monitor the environmental data of the substation and its surroundings; when the monitoring data of any sensor is abnormal, an alarm message is sent to the operation and maintenance personnel to remind them to repair the fault. Since the current alarm signal does not contain the alarm cause, even if the operation and maintenance personnel receive the alarm information, they still do not know the specific cause of the alarm, making it difficult to quickly give an alarm response strategy.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0013] Those skilled in the art may appreciate that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0014] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application.

[0015] In order to solve the problem in the prior art that it is difficult to quickly respond to an alarm because the alarm information does not contain the alarm cause, an embodiment of the present application provides a substation monitoring method.

[0016] The executor of the method may be any computing device that can implement the method, such as a server, a mobile phone, a personal computer, a smart wearable device, a smart robot, and the like.

[0017] In addition, the execution order of different steps is not limited in the embodiment of the present application. When using the method provided in the embodiment of the present application, the execution order of different steps can be adjusted according to actual needs.

[0018] For ease of description, the method provided in the embodiment of the present application is described in detail below by taking a substation monitoring device as the executor of the method as an example.

[0019] like Figure 1As shown, it is a specific implementation flow chart of a substation monitoring method provided in an embodiment of the present application, including the following steps 11 to 17: Step 11: Acquire monitoring data collected by sensors on at least one substation.

[0020] like Figure 2 As shown, the substation monitoring equipment of this embodiment realizes the monitoring of multiple substations through wireless Internet of Things technology. In order to monitor the safety of the operating environment of each substation, various types of wireless sensors are set in each substation. These sensors are used to obtain environmental data (such as temperature, humidity, images, etc.) in and around the substation, and the wireless sensors send the collected monitoring data to the substation monitoring equipment through the FSU (Field Supervision Unit) host via the wireless module.

[0021] Among them, the FSU host and the wireless module use the standard serial RS485 protocol for communication, the information transmission mode is asynchronous, the data bit is 8 bits, the stop bit is 1 bit, there is no check, and the baud rate is 9600bps.

[0022] The RS485 protocol defines the data format and communication rules used on the RS485 bus based on the MODBUSRTU (Modbus Remote Terminal Unit) serial communication protocol. Specifically: The MODBUS RTU communication protocol is adopted. The protocol format includes the read data command format, the device return data format, the write data command format, the device return data format, the forced address setting command format, etc., as follows: Read data command format:

[0023] The device returns data in the following format:

[0024] Write data command format:

[0025] The device returns data in the following format:

[0026] Forced address setting command format:

[0027] The device returns data in the following format:

[0028] Among them, the forced address setting command is used to set the pulse host address, requiring the host and the slave to operate "one-to-one". It is mainly used when the pulse host address is forgotten. The register starting address can only be 0 or 1, and the number of registers is 1 or 2.

[0029] Exception return format

[0030] Error code description: 0x01: indicates an illegal function code; 0x02: indicates an illegal register address; 0x03: indicates illegal data; 0x04: Indicates that the register operation (read / write) is abnormal.

[0031] The registers are specifically defined as follows:

[0032] When reading a register, you can start reading from any position in sequence, but you cannot exceed the position 00 10.

[0033] When writing to a register, you can write to the register marked with W continuously, but you cannot exceed the position 00 06.

[0034] Among them, R means that the register is read-only, W means write-only, and R / W means readable and writable.

[0035] The sensors used in this embodiment include at least temperature and humidity sensors, infrared sensors, access control sensors, smoke sensors, water immersion sensors, electronic fences, vibration sensors and surveillance cameras, as well as sound and light alarms for sending alarm signals at the substation site.

[0036] Among them, temperature and humidity sensors can be installed outside and inside the substation to monitor the temperature and humidity of the substation room and the surrounding environment through telemetry; infrared sensors are usually installed in the outer expansion area of ​​the fan-shaped plate inside the transformer winding in the substation to monitor whether there is anyone or anything illegally approaching the outer expansion area of ​​the fan-shaped plate through telemetry; access control sensors are usually installed at the doors and windows of the substation to monitor whether the doors and windows are illegally opened through telemetry; water immersion sensors are usually installed at a certain distance from the ground inside and outside the substation room to monitor whether there is water accumulation in the substation through telemetry; smoke sensors are usually installed at a certain distance from the ground inside and outside the substation room to monitor whether there is water accumulation in the substation through telemetry; Installed in the substation room, it monitors the smoke concentration in the room by telemetry. Electronic fences are usually installed on the wall outside the substation room, and monitor whether anyone or anything illegally climbs over the wall to enter the substation by telemetry. Vibration sensors usually refer to important equipment in the substation that is easy to be stolen (or moved), and monitor whether anyone illegally moves important equipment by telemetry. Surveillance cameras are usually installed outside and inside the substation room, and are used to monitor image signals inside and outside the substation by telemetry. Sound and light alarms are usually installed inside and outside the substation room, and are used to issue sound and light alarms for illegal behavior by remote control.

[0037] Step 12, based on the corresponding relationship between each sensor and each preset range of its monitoring data, determine the abnormal monitoring data whose acquired monitoring data is not within the preset range, and the type of the target sensor that collected the abnormal monitoring data.

[0038] The preset range refers to the normal range of the monitoring data collected by the sensor. If the collected monitoring data exceeds this range, it is considered that the collected monitoring data is abnormal. The preset range of each sensor is determined based on the specific installation location and the historical monitoring data at the installation location. For the same sensor, when it is installed in different locations, its preset range may be different.

[0039] In the substation monitoring equipment, the correspondence between each sensor and its preset range is stored. Based on the correspondence, it can be determined whether the monitoring data currently collected by the sensor is outside the preset range. If it is outside the preset range, the monitoring data is determined as abnormal monitoring data, and the type of the target sensor that collected the abnormal monitoring data is determined.

[0040] It should be further explained that, in order to distinguish each sensor, an identity code is usually set for each sensor. In the above correspondence, the correspondence between the identity code of the sensor and the preset range is actually stored.

[0041] Step 13: Filter out the target substation where the target sensor is located from the at least one substation.

[0042] The substation monitoring device also stores the sensors installed in each substation. The specific storage method may be: the corresponding relationship between the substation number and the identification code of each sensor installed therein.

[0043] After the target sensor is acquired in step 12, the target substation where the target sensor is located is determined according to the correspondence between the substation number and the identification code of each sensor set therein.

[0044] Step 14: According to the type, at least one sensor that can collect abnormal monitoring data with the target sensor under the same alarm reason is determined as an associated sensor of the target sensor.

[0045] The types of sensors include temperature and humidity sensors, smoke sensors, and other sensors used in the substations listed above. At least one sensor of each type is installed in the substation.

[0046] When the substation environment is abnormal, usually more than one sensor's monitoring data will be abnormal. For example, when a fire occurs in a substation, the ambient temperature of the substation will usually increase and the smoke concentration will increase, so that the temperature sensor and the smoke sensor will collect abnormal monitoring data; for another example, when a flood disaster occurs in a substation, the humidity of the substation environment will usually increase, so that the humidity sensor and the water immersion sensor will collect abnormal monitoring data. It can be seen that when abnormal monitoring data appears in the temperature and humidity sensors, the current alarm cause can be further determined through the monitoring data of other sensors, that is, the alarm cause can be further clarified through the monitoring data of the associated sensors.

[0047] Therefore, in this embodiment, at least one sensor that can collect abnormal monitoring data with the target sensor under the same alarm reason is determined as the associated sensor of the target sensor. For example, the associated sensors of the temperature and humidity sensor include at least a smoke sensor and a water immersion sensor, and when the monitoring data of different associated sensors are abnormal, the corresponding alarm reasons may be different.

[0048] Step 15, based on the geographical location of the target substation, or the connection relationship between the target substation and other substations in the power grid, at least one substation that can issue the same alarm as the target substation under the same alarm reason is determined as an associated substation of the target substation.

[0049] When a natural disaster occurs, substations that are close to each other will usually experience abnormalities at the same time or one after another. Therefore, based on the location of the substation, it is possible to further clarify the alarms caused by reasons such as fire, flooding, earthquake, etc.

[0050] Based on the grid structure (such as the backbone grid layer, the regional grid layer) and / or the transformer level of the substation, there may be connection relationships between different substations, such as superior-subordinate connection relationships. When one of the at least two substations with a connection relationship has an abnormality, it may affect the other substations in the connection relationship, causing abnormalities in other substations. For example, if one of the substations in the connection relationship is abnormally offline, the load of other substations in the connection relationship may increase and the operation may be abnormally offline. It can be seen that based on the geographical location of the substation and the connection relationship between the substations, the cause of the abnormal monitoring data in the target substation can be further determined.

[0051] Therefore, in this embodiment, according to the geographical location of the target substation, or the connection relationship between the target substation and other substations in the power grid, at least one substation that can issue the same alarm as the target substation under the same alarm reason will be determined as an associated substation of the target substation.

[0052] Step 16: Obtain historical monitoring data.

[0053] The historical monitoring data may be stored at the substation monitoring device or in a database that can communicate with the substation monitoring device.

[0054] The historical monitoring data obtained includes at least: the first historical monitoring data of the target sensor, the second historical monitoring data of the associated sensor, and at least one of the third historical monitoring data of the sensor corresponding to the associated substation; the sensor corresponding to the associated substation is the same type of sensor as the target sensor.

[0055] The acquisition of specific historical monitoring data is determined based on the data attributes represented by the abnormal monitoring data. The data attributes include environmental attributes and human attributes.

[0056] When the abnormal monitoring data represents environmental attributes, that is, the abnormal monitoring data is caused by environmental factors, and the specific abnormal monitoring data can be at least one of the data such as temperature, humidity, smoke concentration, vibration value (vibration velocity, vibration acceleration and vibration displacement, etc.), under the influence of environmental factors, the associated sensors of the target sensor in the current target substation and the corresponding sensors in the associated substations may have abnormal monitoring data. Therefore, when the abnormal monitoring data is caused by environmental factors, the acquired historical monitoring data includes the first historical monitoring data of the target sensor, the second historical monitoring data of the associated sensor and the third historical monitoring data of the sensor corresponding to the target substation.

[0057] When the abnormal monitoring data represents human attributes, that is, the abnormal monitoring data is caused by human factors, and the specific abnormal monitoring data can be at least one of the data such as vibration value, signal value of access control sensor, signal value of electronic fence, etc., the abnormality of the above monitoring data caused by human factors usually occurs in a substation, and after the abnormal monitoring data of the above sensor appears, due to different alarm reasons, its associated sensors may also appear abnormal monitoring data. Therefore, when the abnormal monitoring data is caused by human factors, the acquired historical monitoring data includes the first historical monitoring data of the target sensor and the second historical monitoring data of the associated sensor.

[0058] In addition, it should be noted that historical monitoring data is obtained in order to ensure the accuracy of the alarm in the future. Because the sensor may occasionally have false alarms during operation, based on the characteristics of the data collected by the sensor, it can be inferred whether the sensor has generated a false alarm. For example, the increase and decrease of temperature often occur slowly. If the temperature collection values ​​of two adjacent temperature sensors differ greatly, or the temperature fluctuates in a short period of time, the temperature sensor itself may be faulty. Therefore, obtaining historical monitoring data is conducive to eliminating the impact of the sensor's own fault on the alarm and improving the accuracy of the alarm.

[0059] Step 17, based on at least one of the abnormal monitoring data, the first historical monitoring data, the second historical monitoring data and the third historical monitoring data, and the historical alarm records containing the abnormal monitoring data of the target sensor, determine the alarm information containing the cause of the alarm to be sent to the operation and maintenance personnel for the target substation and / or associated substations. After issuing an alarm message, the substation monitoring equipment will record the time when the alarm was triggered, the abnormal monitoring data that occurred, the historical monitoring data of at least one sensor where the abnormal monitoring data occurred (historical monitoring data, usually based on the type of sensor, captures data over a period of time), the historical monitoring data of the associated sensors of the sensor where the abnormal monitoring data occurred, the historical monitoring data of the corresponding sensors in the associated substation, the reason for the alarm, and whether the alarm is correct.

[0060] Among them, the cause of the alarm is the accurate alarm cause determined by the operation and maintenance personnel; the correctness of the alarm is the information determined by the operation and maintenance personnel as to whether an abnormality actually occurs, that is, whether the alarm of this historical alarm is accurate (including the accuracy of the abnormal monitoring data and the accuracy of the judgment on the cause of the alarm).

[0061] The historical alarm records containing abnormal monitoring data of the target sensor at least include the abnormal monitoring data that triggers the alarm and its corresponding historical monitoring data, the reason for triggering the alarm, and whether the alarm is correct or not.

[0062] Based on at least one of the abnormal monitoring data, the first historical monitoring data, the second historical monitoring data and the third historical monitoring data, and each historical alarm record including the abnormal monitoring data of the target sensor, an alarm message including a cause of triggering an alarm for the target substation and / or the associated substations to be sent to an operation and maintenance personnel is determined, specifically including the following two situations: Case 1: When the abnormal monitoring data is caused by environmental factors, the determination of the alarm information includes the following steps 1711 to 1713: Step 1711, based on the first historical monitoring data, the second historical monitoring data and the third historical monitoring data, respectively determine how the first historical monitoring data changes over time, how the second historical monitoring data changes over time and how the third historical monitoring data changes over time; form a first vector with the data of each determined change.

[0063] Determine how the historical monitoring data changes over time, which can be the rate of change of the historical monitoring data over time within a unit time, and generate a change rate sequence for each historical monitoring data; merge the change rate sequence of the first historical monitoring data, the change rate sequence of the second historical monitoring data, and the change rate sequence of the third historical monitoring data to form a first vector.

[0064] In order to highlight the changes in historical monitoring data, the time difference between the moment when the monitoring data suddenly changes and the moment when the abnormal monitoring data appears can be further obtained from the historical monitoring data; the time difference corresponding to the first historical monitoring data, the time difference corresponding to the second historical monitoring data and the time difference corresponding to the third historical monitoring data are written into the first vector respectively.

[0065] It should be noted that if there is no corresponding abnormal monitoring data in the second historical monitoring data or the third historical monitoring data, the corresponding time difference value is 0.

[0066] Step 1712, based on the corresponding historical alarm records, determine the change of the corresponding first historical monitoring data over time, the change of the corresponding second historical monitoring data over time, and the change of the corresponding third historical monitoring data over time, and form each second vector with the data of each determined change.

[0067] The method of determining the first vector in the above step 1711 is used to form second vectors corresponding to each historical alarm record by using the change rate of each historical monitoring data and the corresponding time difference in each historical alarm record.

[0068] In the historical alarm records, there may be more than one alarm record caused by abnormal monitoring data of the target sensor. Therefore, in this step, the alarm records caused by abnormal monitoring data of the target sensor are processed respectively to obtain corresponding second vectors respectively.

[0069] Step 1713: Determine, based on the similarities between the first vector and each second vector, alarm information including the cause of the alarm to be sent to the operation and maintenance personnel for the target substation and / or associated substations.

[0070] Calculate the similarities between the first vector and each second vector, obtain a second vector with the highest similarity to the first vector, and determine the historical alarm record corresponding to the second vector; If the alarm is accurately recorded in the corresponding historical alarm record, the cause of the alarm is obtained from the corresponding historical alarm record to determine the alarm information containing the cause of the alarm sent to the operation and maintenance personnel for the target substation; if the alarm is inaccurately recorded in the corresponding historical alarm record, no alarm information is issued for the time being.

[0071] Since the alarm is caused by environmental factors, this type of alarm may occur in an associated substation, so a corresponding alarm message is also issued to the associated substation, and it is recorded in the alarm information of the associated substation that the alarm is an associated alarm.

[0072] Case 2, when the abnormal monitoring data is caused by human factors, the determination of the alarm information includes the following steps 1721 to 1723: Step 1721: Based on the first historical monitoring data and the second historical monitoring data, respectively determine how the first historical monitoring data changes over time and how the second historical monitoring data changes over time; and form a third vector with the data of each determined change.

[0073] Determine the change of historical monitoring data over time, which can be the change rate of historical monitoring data over time in unit time, and generate a change rate sequence for each historical monitoring data; merge the change rate sequence of the first historical monitoring data and the change rate sequence of the second historical monitoring data to form a third vector.

[0074] In order to highlight the changes in historical monitoring data, the time difference between the moment when the monitoring data suddenly changes and the moment when the abnormal monitoring data appears can be further obtained from the historical monitoring data; the time difference corresponding to the first historical monitoring data and the time difference corresponding to the second historical monitoring data are written into the third vector respectively.

[0075] It should be noted that if there is no corresponding abnormal monitoring data in the second historical monitoring data or the third historical monitoring data, the corresponding time difference value is 0.

[0076] Step 1722: Based on the historical monitoring data, determine the change of the first historical monitoring data over time and the change of the second historical monitoring data over time, and form fourth vectors with the determined data of each change.

[0077] The method of determining the third vector in the above step 1721 is used to form fourth vectors corresponding to each historical alarm record by using the change rate of each historical monitoring data corresponding to each historical alarm record and the corresponding time difference.

[0078] Step 1723: Determine, based on the similarities between the third vector and each fourth vector, an alarm message including the cause of the alarm to be sent to the operation and maintenance personnel for the target substation.

[0079] Calculating the similarities between the third vector and each fourth vector, and determining the historical alarm record corresponding to the fourth vector having the highest similarity to the third vector; If the alarm recorded in the corresponding historical alarm record is accurate, the cause of the alarm is obtained from the corresponding historical alarm record to determine the alarm information including the cause of the alarm sent to the operation and maintenance personnel for the target substation.

[0080] In this embodiment, since the associated sensor is a sensor that can collect abnormal monitoring data with the target sensor under the same alarm reason; the target substation is a substation that can issue the same alarm as the target substation under the same alarm reason, and the historical alarm record contains the alarm reason; after obtaining the abnormal monitoring data of the sensor, the embodiment of the present application combines the first historical monitoring data of the target sensor, the second historical monitoring data of the associated sensor, at least one of the third historical monitoring data of the sensor corresponding to the associated substation, and each historical alarm record containing the abnormal monitoring data of the target sensor, and can determine the cause of the target sensor issuing the abnormal monitoring data, thereby writing the cause of the alarm into the alarm information, so that the operation and maintenance personnel can quickly give an alarm response strategy.

[0081] In order to solve the problem in the prior art that it is difficult to respond to alarms quickly because the alarm information does not contain the cause of the alarm, based on the same inventive concept as the above-mentioned embodiment of the present application, embodiment 2 of the present application provides a substation monitoring device.

[0082] The specific structural diagram of the device is shown in Figure 3 As shown, it includes the following functional units 31-37: The data acquisition unit 31 is used to acquire various monitoring data collected by various sensors on at least one substation.

[0083] The abnormal data determination unit 32 determines abnormal monitoring data that is not within the preset range and the type of the target sensor that collected the abnormal monitoring data based on the corresponding relationship between each sensor and each preset range of its monitoring data.

[0084] The information screening unit 33 is used to screen out the target substation where the target sensor is located from the at least one substation.

[0085] The associated sensor determination unit 34 is used to determine, according to the type, at least one sensor that can collect abnormal monitoring data with the target sensor under the same alarm cause as an associated sensor of the target sensor.

[0086] The associated substation determination unit 35 is used to determine at least one substation that can issue the same alarm as the target substation under the same alarm reason as an associated substation of the target substation based on the geographical location of the target substation or the connection relationship between the target substation and other substations in the power grid.

[0087] The historical data acquisition unit 36 ​​is used to acquire historical monitoring data; the historical monitoring data includes at least one of the first historical monitoring data of the target sensor, the second historical monitoring data of the associated sensor, and the third historical monitoring data of the sensor corresponding to the associated substation; the sensor corresponding to the associated substation is the same type of sensor as the target sensor.

[0088] When the abnormal monitoring data is an abnormality caused by environmental factors, the historical monitoring data includes: first historical monitoring data of the target sensor, second historical monitoring data of the associated sensor and third historical monitoring data of the sensor corresponding to the target substation.

[0089] When the abnormal monitoring data is an abnormality caused by human factors, the historical monitoring data includes first historical monitoring data of the target sensor and second historical monitoring data of the associated sensor.

[0090] The alarm unit 37 determines the alarm information including the cause of the alarm to be sent to the operation and maintenance personnel for the target substation and / or associated substations based on at least one of the abnormal monitoring data, the first historical monitoring data, the second historical monitoring data and the third historical monitoring data, and the historical alarm records including the abnormal monitoring data of the target sensor; the historical alarm records include at least the abnormal monitoring data that triggers the alarm, the corresponding historical monitoring data, the cause of the alarm and whether the alarm is correct.

[0091] When the abnormal monitoring data is an abnormality caused by environmental factors, the determination of the alarm information specifically includes: Based on the first historical monitoring data, the second historical monitoring data and the third historical monitoring data, respectively determine the change of the first historical monitoring data over time, the change of the second historical monitoring data over time and the change of the third historical monitoring data over time; form a first vector with the data of each determined change; Based on the corresponding historical alarm records, determine the change of the corresponding first historical monitoring data over time, the change of the corresponding second historical monitoring data over time, and the change of the corresponding third historical monitoring data over time, and form the data of each determined change into each second vector; According to the similarities between the first vector and the second vectors, an alarm message including an alarm triggering reason to be sent to the operation and maintenance personnel for the target substation and / or the associated substations is determined.
