Description

Technical Field

[0001] This invention relates to the field of power system monitoring technology, and in particular to a method and device for monitoring the remote control function of automated switches. Background Technology

[0002] The three remote functions of power system automation switchgear include telemetry, remote signaling, and remote control. The application and management of these three functions have greatly promoted the development of power grid automation. Telemetry and remote signaling functions operate in real-time, allowing for timely control of faults in these remote functions. Remote control involves two steps: remote setting and remote execution. Remote control requires coordination between hardware and software, as well as electrical and mechanical aspects. Ensuring the normal operation of remote control requires multi-faceted management. However, remote control functions are only used at specific times, making defects and faults difficult to detect.

[0003] Currently, the main method for remote control functionality involves manually observing the status of terminal equipment and then manually labeling the remote control function status. Labeling types can be divided into "remote control function normal" and "remote control function missing." However, this method suffers from problems such as the inability to promptly detect remote control function defects, slow control speed, and high labor costs. It is insufficient to meet the operational control requirements of large-scale automated switching equipment, thereby affecting the emergency dispatch capabilities of the power grid. Summary of the Invention

[0004] This invention provides a method and device for monitoring the remote control function of automated switches, which solves the problems of current remote control methods, such as the inability to detect remote control function defects in a timely manner, slow control speed, and high labor costs. These methods are insufficient to meet the operation and control requirements of large-scale automated switchgear, thus affecting the emergency dispatch capability of the power grid.

[0005] The first aspect of this invention provides a method for monitoring the remote control function of automated switches, applied to a power grid remote control function management system. The power grid remote control function management system includes multiple automated switchgear devices and a communication terminal, wherein the multiple automated switchgear devices are communicatively connected to the communication terminal, comprising:

[0006] In response to the received monitoring request information, the target automated switching equipment corresponding to the monitoring request information is determined and the first remote signaling data corresponding to the communication terminal is obtained;

[0007] Compare the first remote signaling data with the preset first threshold data;

[0008] If the first remote signaling data is less than the preset first threshold data, the target result is determined by using the return signal data to determine whether the active function is missing;

[0009] If the first remote signaling data is greater than or equal to the preset first threshold data, then the target result is determined based on the second remote signaling data corresponding to the automated switching equipment and the return signal data.

[0010] Optionally, the step of determining the target automated switching equipment corresponding to the monitoring request information and obtaining the first remote signaling data corresponding to the communication terminal in response to the received monitoring request information includes:

[0011] In response to the received monitoring request information, the target automated switching device corresponding to the monitoring request information is determined;

[0012] Obtain the online time corresponding to the communication terminal within a unit of time;

[0013] The online time and the unit time are used to perform calculations to generate the corresponding first remote signaling data;

[0014] Wherein, the first remote signaling data is the online rate of the communication terminal within the unit time period;

[0015] The formula for calculating the first remote signaling data is:

[0016]

[0017] In the formula, S represents the first remote signaling data, T represents the online time, and Tonline represents the time spent online. S This represents the unit of time.

[0018] Optionally, the step of determining the target result based on the second remote signaling data corresponding to the automated switching equipment and the return signal data if the first remote signaling data is greater than or equal to the preset first threshold data includes:

[0019] If the first remote signaling data is greater than or equal to the preset first threshold data, then the second remote signaling data and the return signal data corresponding to the automated switching equipment are obtained;

[0020] The second remote signaling data includes energy storage status data, SF6 abnormal signal data, terminal device fault data, local / remote status data, lockout closing signal data, lockout opening signal or disconnector status data.

[0021] The second remote signaling data is analyzed. If any of the following defect types exist: energy storage abnormality defect, SF6 abnormality defect, terminal device failure defect, lockout closing defect, lockout opening defect, or switch in cold standby state defect, then the target result is determined to be remote control function missing.

[0022] When there is a local state defect, the return signal data is used to determine whether the active function is missing. If the active function is missing, the target result is determined to be a missing remote control function.

[0023] If no defect type associated with the second remote signaling data exists, the active function is determined to be missing by using the return signal data. If the active function is missing, the target result is determined to be a missing remote control function.

[0024] Optionally, determining whether the active function is missing specifically involves:

[0025] The number of failures associated with the return-to-cathode signal data that the target automated switching equipment did not respond to within a preset time period is counted.

[0026] When the number of failures exceeds the preset failure threshold for remote control, it is determined that the active function is missing, and the target result is determined to be a missing remote control function.

[0027] Optionally, it also includes:

[0028] When the target result is that the remote control function is missing and the active function is missing, the number of successful associations of the return-to-cause signal data fed back by the target automated switching device within a preset time period is counted.

[0029] If the number of successful attempts exceeds the preset remote control recovery threshold, then the target result is updated.

[0030] The second aspect of this invention provides a remote control function monitoring device for automated switches, applied to a power grid remote control function management system. The power grid remote control function management system includes multiple automated switchgear devices and a communication terminal, wherein the multiple automated switchgear devices are communicatively connected to the communication terminal, comprising:

[0031] The response module is used to respond to the received monitoring request information, determine the target automated switching equipment corresponding to the monitoring request information, and obtain the first remote signaling data corresponding to the communication terminal;

[0032] The comparison module is used to compare the first remote signaling data with the preset first threshold data;

[0033] The first data processing module is used to determine the target result by using return-to-home signal data to determine whether the active function is missing if the first remote signaling data is less than the preset first threshold data.

[0034] The second data processing module is used to determine the target result based on the second remote signaling data corresponding to the automated switching equipment and the return signal data if the first remote signaling data is greater than or equal to the preset first threshold data.

[0035] Optionally, the response module includes:

[0036] The target automated switchgear determination submodule is used to determine the target automated switchgear corresponding to the received monitoring request information in response to the monitoring request information.

[0037] The online time acquisition submodule is used to acquire the online time of the communication terminal within a unit of time.

[0038] The calculation submodule is used to perform calculations using the online time and the unit time to generate corresponding first remote signaling data;

[0039] Wherein, the first remote signaling data is the online rate of the communication terminal within the unit time period;

[0040] The formula for calculating the first remote signaling data is:

[0041]

[0042] In the formula, S represents the first remote signaling data, T represents the online time, and Tonline represents the time spent online. S This represents the unit of time.

[0043] Optionally, the second data processing module includes:

[0044] The data acquisition submodule is used to acquire the second remote signaling data and the return signal data corresponding to the automated switching equipment if the first remote signaling data is greater than or equal to the preset first threshold data.

[0045] The second remote signaling data includes energy storage status data, SF6 abnormal signal data, terminal device fault data, lockout closing signal data, lockout opening signal data, or disconnector status data.

[0046] The first determination submodule is used to parse the second remote signaling data. When any of the following defect types exist: energy storage abnormality defect, SF6 abnormality defect, terminal device failure defect, lockout closing defect, lockout opening defect, or switch in cold standby state defect, the target result is determined to be remote control function missing.

[0047] The second determination submodule is used to determine whether the active function is missing when there is a local state defect by using the return signal data. If the active function is missing, the target result is determined to be a missing remote control function.

[0048] The third determination submodule is used to determine whether the active function is missing when there is no defect type associated with the second remote signaling data, by using the return signal data. If the active function is missing, the target result is determined to be a missing remote control function.

[0049] Optionally, determining whether the active function is missing specifically involves:

[0050] The number of failures associated with the return-to-cathode signal data that the target automated switching equipment did not respond to within a preset time period is counted.

[0051] When the number of failures exceeds the preset failure threshold for remote control, it is determined that the active function is missing, and the target result is determined to be a missing remote control function.

[0052] As can be seen from the above technical solutions, the present invention has the following advantages:

[0053] In this invention, in response to a received monitoring request, the target automated switchgear corresponding to the monitoring request is identified, and the first remote signaling data corresponding to the communication terminal is acquired. The first remote signaling data is compared with a preset first threshold data. If the first remote signaling data is less than the preset first threshold data, the target result is determined by using return-to-calibration signal data to determine whether there is a missing active function. If the first remote signaling data is greater than or equal to the preset first threshold data, the target result is determined based on the second remote signaling data and return-to-calibration signal data corresponding to the automated switchgear. This invention solves the problems of current remote control methods, such as the inability to detect remote control function defects in a timely manner, slow control speed, and high labor costs, which make it difficult to meet the operation and control of large-scale automated switchgear and thus affect the emergency dispatch capability of the power grid. By combining passive signal detection and comparison function and active remote control preset management function, the management of remote control function of automated switchgear is made complementary, further strengthening the control of remote control function of automated switchgear.

[0059] This invention provides a method and apparatus for monitoring the remote control function of automated switches, which addresses the problems of current remote control methods, such as the inability to detect remote control function defects in a timely manner, slow control speed, and high labor costs, making it difficult to meet the operation and control requirements of large-scale automated switchgear, thereby affecting the emergency dispatch capability of the power grid.

[0060] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0061] Please see Figure 1 , Figure 1 The flowchart illustrates the steps of a remote control function monitoring method for an automated switch provided in Embodiment 1 of the present invention.

[0062] This invention provides a method for monitoring the remote control function of automated switches, applied to a power grid remote control function management system. The power grid remote control function management system includes multiple automated switchgear and a communication terminal. The multiple automated switchgear are communicatively connected to the communication terminal, including:

[0063] Step 101: In response to the received monitoring request information, determine the target automated switchgear corresponding to the monitoring request information and obtain the first remote signaling data corresponding to the communication terminal.

[0064] The power grid remote control function management system refers to a management system used to call up power grid system data information and remote signaling function related information for comparison and judgment, and complete the real-time autonomous control and processing of remote control functions.

[0065] Automated switching equipment refers to electrical equipment used to determine whether remote control functionality is missing.

[0066] A communication terminal refers to a device used to communicate with automated switching equipment. The online time of this communication is used as a calculation parameter for the first remote signaling data. The first remote signaling data is one of the criteria used to determine whether the automated switching equipment has a missing remote control function.

[0067] Monitoring request information refers to a monitoring command received to check whether the remote control function of automated switching equipment is missing, and it carries the data code of the automated switching equipment being monitored.

[0068] In this embodiment of the invention, in response to the received monitoring request information, the monitoring request information is read, the data code is obtained, the automated switchgear associated with the data code is matched as the target automated switchgear, and the first remote signaling data corresponding to the communication terminal is obtained.

[0069] Step 102: Compare the first remote signaling data with the preset first threshold data.

[0070] The preset first threshold data refers to the threshold data used to determine whether the target automated switching equipment has a missing remote control function.

[0071] In this embodiment of the invention, the first remote signaling data is compared with the preset first threshold data.

[0072] Step 103: If the first remote signaling data is less than the preset first threshold data, the target result is determined by using the return signal data to determine whether the active function is missing.

[0073] In this embodiment of the invention, if the first remote signaling data is less than the preset first threshold data, the number of failures associated with the return calibration signal data that the target automated switchgear did not return within a preset time period is counted. When the number of failures is greater than the preset remote control failure threshold, it is determined that the active function is missing. When either the first remote signaling data is less than the preset first threshold data or the active function is missing is met, the target result of the target automated switchgear is determined to be that the remote control function is missing.

[0074] It is worth mentioning that, in this invention, the active function refers to the active remote control preset management function, and the passive signal detection and comparison function composed of the first remote signaling data and the second remote signaling data.

[0075] Step 104: If the first remote signaling data is greater than or equal to the preset first threshold data, then the target result is determined based on the second remote signaling data and the return signal data corresponding to the automated switching equipment.

[0076] In this embodiment of the invention, if the first remote signaling data is greater than or equal to a preset first threshold data, then the second remote signaling data and return signal data corresponding to the automated switchgear are acquired. The second remote signaling data includes energy storage status data, SF6 abnormal signal data, terminal device fault data, local / remote status data, interlocking closing signal data, interlocking opening signal data, or disconnector status data. Under the condition that the first remote signaling data is greater than or equal to the preset first threshold data, the second remote signaling data is parsed. If any of the following defect types exists: energy storage abnormality defect, SF6 abnormality defect, terminal device fault defect, interlocking closing defect, interlocking opening defect, or switch in cold standby state, then the target result is determined to be remote control function. Missing; Under the condition that the first remote signaling data is greater than or equal to the preset first threshold data, when there is a local state defect, the active function is determined to be missing by using the return signal data. If the active function is missing, the target result is determined to be a missing remote control function when there is a local state defect and the missing active function is satisfied. Under the condition that the first remote signaling data is greater than or equal to the preset first threshold data, when there is no defect type associated with the second remote signaling data, the active function is determined to be missing by using the return signal data. If the active function is missing, the target result is determined to be a missing remote control function when there is no defect type associated with the second remote signaling data and the missing active function is satisfied.

[0077] In this invention, in response to a received monitoring request, the target automated switchgear corresponding to the monitoring request is identified, and the first remote signaling data corresponding to the communication terminal is acquired. The first remote signaling data is compared with a preset first threshold data. If the first remote signaling data is less than the preset first threshold data, the target result is determined by using return-to-calibration signal data to determine whether there is a missing active function. If the first remote signaling data is greater than or equal to the preset first threshold data, the target result is determined based on the second remote signaling data and return-to-calibration signal data corresponding to the automated switchgear. This invention solves the problems of current remote control methods, such as the inability to detect remote control function defects in a timely manner, slow control speed, and high labor costs, which make it difficult to meet the operation and control of large-scale automated switchgear and thus affect the emergency dispatch capability of the power grid. By combining passive signal detection and comparison function and active remote control preset management function, the management of remote control function of automated switchgear is made complementary, further strengthening the control of remote control function of automated switchgear.

[0078] Please see Figure 2 , Figure 2 This is a flowchart illustrating the steps of a remote control function monitoring method for an automated switch provided in Embodiment 2 of the present invention.

[0079] This invention provides a method for monitoring the remote control function of automated switches, applied to a power grid remote control function management system. The power grid remote control function management system includes multiple automated switchgear and a communication terminal. The multiple automated switchgear are communicatively connected to the communication terminal, including:

[0080] Step 201: In response to the received monitoring request information, determine the target automated switching equipment corresponding to the monitoring request information.

[0081] In this embodiment of the invention, the specific implementation process of step 201 is similar to that of step 101, and will not be repeated here.

[0082] Step 202: Obtain the online time of the communication terminal within a unit of time.

[0083] Step 203: Calculate the online time and unit time to generate the corresponding first remote signaling data.

[0084] Furthermore, the first remote signaling data is the online rate of the communication terminal within a unit of time.

[0085] The formula for calculating the first remote information data is:

[0086]

[0087] In the formula, S represents the first remote signaling data, T represents the online time, and T0 represents the online time. S Indicates a unit of time.

[0088] In this embodiment of the invention, steps 202-203 are specifically applied as follows: when in response to receiving monitoring request information, the online time of the communication terminal in the past hour is obtained and calculated as follows: online rate in the past hour = online communication time of the communication terminal connected to the target automated switch equipment in the past hour / 60 minutes * 100%.

[0089] Step 204: Compare the first remote signaling data with the preset first threshold data.

[0090] In this embodiment of the invention, the first remote signaling data is the actual online rate, and the preset first threshold data is 90%, which specifically refers to the total online rate per unit time * 90%.

[0091] Step 205: If the first remote signaling data is less than the preset first threshold data, the target result is determined by using the return signal data to determine whether the active function is missing.

[0092] In this embodiment of the invention, the specific implementation process of step 205 is similar to that of step 103, and will not be repeated here.

[0093] Step 206: If the first remote signaling data is greater than or equal to the preset first threshold data, then the target result is determined based on the second remote signaling data and the return signal data corresponding to the automated switching equipment.

[0094] Furthermore, step 206 includes the following steps:

[0095] S11. If the first remote signaling data is greater than or equal to the preset first threshold data, then obtain the second remote signaling data and the return signal data corresponding to the automated switching equipment.

[0096] The second remote signaling data includes energy storage status data, SF6 abnormal signal data, terminal device fault data, local / remote status data, lockout closing signal data, lockout opening signal data, or disconnector status data.

[0097] The return-to-calibration signal data refers to the remote preset return-to-calibration signal. Specifically, the terminal device in the power grid remote control function management system sends a remote preset command to each target automated switchgear, but does not send a remote execution command. After receiving the remote preset command, the automated switchgear will return a remote preset return-to-calibration signal to the power grid remote control function management system when the automated switchgear is operating normally.

[0098] The first remote signaling data specifically refers to the system data of the power grid remote control function management system. It is calculated by querying the online communication time between the communication terminal and the target automated switching equipment in real time.

[0099] The second type of remote signaling data is remote signaling data. Remote signaling data is a digital signal with only two states: "true" or "false". For example, in energy storage status data, a true "no energy storage" signal indicates that the device has not stored energy, while a false "no energy storage" signal indicates that the device has stored energy; in terminal device fault data, the true and false signals for the "remote / local" status represent the remote and local states, respectively. In disconnector status data, the true and false signals for the disconnector status represent the closed and open states, respectively.

[0100] In this embodiment of the invention, if the first remote signaling data is greater than or equal to a preset first threshold data, then the second remote signaling data and the return signal data corresponding to the automated switching equipment are obtained.

[0101] S12. Analyze the second remote signaling data. If any of the following defect types exist: energy storage abnormality defect, SF6 abnormality defect, terminal device failure defect, lockout closing defect, lockout opening defect, or switch in cold standby state defect, then the target result is determined to be remote control function missing.

[0102] In this embodiment of the invention, the second remote signaling data is analyzed. When any of the following defect types exist: energy storage abnormality defect, SF6 abnormality defect, terminal device failure defect, lockout closing defect, lockout opening defect, or switch in cold standby state, that is, when any of the following defect types exist in the second remote signaling data: "no energy storage" state is true, "SF6 abnormality" signal is true, "terminal device failure" is true, "lockout closing" signal is true, "lockout opening" signal is true, or disconnector switch is in open state, the target result is determined to be remote control function missing.

[0103] S13. When there is a local state defect, the active function is missing by using the return signal data. If the active function is missing, the target result is determined to be a missing remote control function.

[0104] In this embodiment of the invention, when the second remote signaling data has a "local / remote" status that is local, it is determined to be a local status defect. Then, the return signal data is used to determine whether the active function is missing. If the active function is missing, the target result is determined to be a remote control function missing.

[0105] S14. When there is no defect type associated with the second remote signaling data, the active function is determined to be missing by using the return signal data. If the active function is missing, the target result is determined to be the remote control function missing.

[0106] In this embodiment of the invention, when there is no defect type such as energy storage abnormality defect, SF6 abnormality defect, terminal device failure defect, local status defect, lockout closing defect, lockout opening defect, or switch in cold standby state defect, the active function is determined to be missing by using the return-to-home signal data. If the active function is missing, the target result is determined to be remote control function missing. If the active function is not missing, the target result is remote control function not missing.

[0107] Furthermore, the determination of whether the active function is missing in steps 205 and 206 specifically involves:

[0108] S21. Count the number of failures associated with the return signal data of the target automated switching equipment that did not return within a preset time period.

[0109] The terminal devices in the power grid remote control function management system send remote control preset commands to each target automated switching equipment, but do not send remote control execution commands.

[0110] When an automated switchgear receives a remote preset command, it will return a remote preset correction signal to the power grid remote control function management system if the automated switchgear is operating normally, indicating that the remote preset was successful.

[0111] If the power grid remote control function management system does not receive a remote control preset return signal within the specified time or the received remote control preset return signal is incorrect, the remote control preset is considered to have failed.

[0112] In this embodiment of the invention, the number of failures associated with the return-to-caution signal data that the target automated switching equipment did not return within a preset time period is counted.

[0113] S22. When the number of failures exceeds the preset failure threshold for remote control, it is determined that the active function is missing, and the target result is determined to be the missing remote control function.

[0114] The remote control preset failure threshold is defined as k1. When the number of consecutive remote control preset failures of an automated switchgear exceeds k1, the remote control function management system will determine that the automated switchgear lacks remote control functionality.

[0115] In this embodiment of the invention, when the number of failures exceeds the preset failure threshold for remote control, it is determined that the active function is missing, and the target result is determined to be that the remote control function is missing.

[0116] Furthermore, steps 205 and 206 also include:

[0117] A1. When the target result is that the remote control function is missing and the active function is missing, count the number of times the return signal data fed back by the target automated switchgear is successfully associated within a preset time period.

[0118] In this embodiment of the invention, when the target result is that the remote control function is missing and the active function is missing, the number of successful associations of the return signal data fed back by the target automated switching equipment within a preset time period is counted.

[0119] A2. If the number of successful attempts exceeds the preset recovery threshold for remote control, then update the target result.

[0120] The remote control preset recovery threshold is defined as k2. When the remote control function of the automated switchgear is missing due to preset failure, if the number of consecutive successful remote control presets of the automated switchgear exceeds k2, the power grid remote control function management system will determine that the remote control function defect status caused by preset failure is cancelled.

[0121] In this embodiment of the invention, if the number of successful attempts exceeds the preset remote control recovery threshold, the target result is updated.

[0122] Furthermore, it also includes:

[0123] Step 207: When the first remote signaling data is less than the preset first threshold data and the active function is missing;

[0124] Alternatively, there may be abnormal defects in energy storage and a lack of active functions;

[0125] Alternatively, there may be an SF6 anomaly defect and a lack of active functionality;

[0126] Alternatively, if there is a terminal device malfunction or defect and the active function is missing, the target automated switchgear is determined to have an unplanned remote control function deficiency and an alarm signal is output.

[0127] It is worth mentioning that if the first remote signaling data is less than the preset first threshold data, it is determined that there is an offline defect.

[0128] It should be noted that the four types of defects—offline defects, energy storage abnormalities, SF6 abnormalities, and terminal device malfunctions—are usually caused by external damage and require close attention and handling by maintenance personnel.

[0129] In this embodiment of the invention, when the first remote signaling data is less than the preset first threshold data and the active function is missing, or there is an energy storage abnormality defect and the active function is missing, or there is an SF6 abnormality defect and the active function is missing, or there is a terminal device fault defect and the active function is missing, then the target automated switchgear is determined to have an unplanned remote control function missing and an alarm signal is output.

[0130] Step 208: When there is a local state defect and active functions are missing;

[0131] Or, a defect in the locking and closing mechanism and an active function;

[0132] Or, the circuit breaker has a lockout tripping defect and an active function;

[0133] Alternatively, if the switch is in a cold standby state with a defect but has active functionality, the target automated switchgear is determined to have a planned remote control function deficiency and is marked accordingly.

[0134] It should be noted that the four types of defects—local status defects, interlocking closing defects, interlocking opening defects, and switches in cold standby status defects—are usually caused by planned operations by maintenance personnel. They will recover automatically after the project is completed. Maintenance personnel only need to understand the situation and follow up continuously.

[0135] In this embodiment of the invention, when there is a local state defect and the active function is missing, or a blocking closing defect and the active function or a blocking opening defect and the active function or a switch is in a cold standby state defect and the active function is missing, the target automated switchgear is determined to have a planned remote control function missing and is marked.

[0136] Application example:

[0137] like Figure 3 As shown, the passive signal detection and comparison function is executed through the power grid remote control management system, as detailed below:

[0138] The first and second remote signaling data are collected to determine whether the target automated switchgear is functioning properly. The remote control function of the target automated switchgear is considered to be missing if any of the following conditions are met in the remote signaling data:

[0139] (1) The online rate of communication terminal equipment in the past hour is less than 90%.

[0140] Online rate in the past hour = (Device online time in the past hour / 60 minutes) * 100%

[0141] The online rate within the past hour, calculated using the formula for the first remote signaling data, determines whether the communication terminal and the target automated switching equipment are offline.

[0142] (2) The "no energy storage" status in the remote signaling data is true.

[0143] (3) The “SF6 abnormal” signal in the remote signaling data is true.

[0144] (4) The "terminal device failure" in the remote signaling data is true.

[0145] (5) The "local / remote" status in the remote signaling data is local.

[0146] (6) The “lock-in” signal in the remote signaling data is true.

[0147] (7) The "blocking trip" signal in the remote signaling data is true.

[0148] (8) The disconnector status in the remote signaling data is open.

[0149] (1) represents the first remote signaling data, and (2)-(8) represent the second remote signaling data.

[0150] Example: (2) A true "no energy stored" signal indicates that the device has no energy stored, and a false "no energy stored" signal indicates that the device has energy stored; (4) The true and false signals of the "remote / local" status represent the remote status and the local status, respectively. (8) The true and false signals of the disconnecting switch status represent the closed status and the open status, respectively.

[0151] The active remote control preset management function is executed through the power grid remote control function management system, as follows:

[0152] The active remote control preset management function refers to the power grid remote control function management system continuously and periodically sending remote control preset commands to each automated switchgear, but not issuing remote control execution commands.

[0153] When an automated switchgear receives a remote preset command, it will return a remote preset correction signal to the power grid remote control function management system if the automated switchgear is operating normally, indicating that the remote preset was successful.

[0154] If the power grid remote control function management system does not receive a remote control preset return signal within the specified time or the received remote control preset return signal is incorrect, the remote control preset is considered to have failed.

[0155] The remote control preset failure threshold is defined as k1. When the number of consecutive remote control preset failures of the automated switchgear exceeds k1, the power grid remote control function management system will determine that the automated switchgear lacks remote control function.

[0156] The remote control preset recovery threshold is defined as k2. When an automated switch has a remote control function deficiency due to preset failure, if the number of consecutive successful remote control presets of the automated switch exceeds k2, the power grid remote control function management system will determine that the remote control function defect status caused by preset failure is cancelled.

[0157] The types of remote control defects that can be detected by the active remote control preset management system include:

[0158] (1) The communication signal is unstable when the device is set to remote control.

[0159] (2) The “Distance / Local” knob is in the local position.

[0160] (3) Communication failure of automated switching equipment and terminal communication equipment.

[0161] (4) The control system of the automated switchgear malfunctions.

[0162] The relationship between the passive signal detection and comparison function and the active remote control preset management function is shown in Table 1 below:

[0163] Table 1. Relationship between Passive Signal Detection Comparison Function and Active Remote Control Preset Management Function

[0164]

[0165]

[0166] (1) A low online rate of communication terminal equipment (less than 90%) will directly lead to the loss of remote control function, and will also cause the active remote control preset to fail.

[0167] (2) The data from the second remote signaling point can be used to determine whether the remote control function is normal only when the online rate of the communication terminal equipment is normal (greater than or equal to 90%).

[0168] (3) Any abnormality of any remote signaling point in the passive signal detection and comparison function will result in the loss of remote control function. In particular, low equipment online rate and "local / remote" status will also cause the active remote control preset to fail.

[0169] (4) Even if the passive signal detection and comparison functions are all normal, the active remote control preset may still fail. The reason for this defect is that the terminal communication equipment and the automated switchgear are not communicating properly or the automated equipment program is down.

[0170] Therefore, by combining the passive signal detection and comparison function with the active remote control preset management function, the management of the remote control function of automated switchgear is made complementary, and the control of the remote control function of automated switchgear is further strengthened.

[0171] In this invention, in response to a received monitoring request, the target automated switchgear corresponding to the monitoring request is identified, and the first remote signaling data corresponding to the communication terminal is acquired. The first remote signaling data is compared with a preset first threshold data. If the first remote signaling data is less than the preset first threshold data, the target result is determined by using return-to-calibration signal data to determine whether there is a missing active function. If the first remote signaling data is greater than or equal to the preset first threshold data, the target result is determined based on the second remote signaling data and return-to-calibration signal data corresponding to the automated switchgear. This invention solves the problems of current remote control methods, such as the inability to detect remote control function defects in a timely manner, slow control speed, and high labor costs, which make it difficult to meet the operation and control of large-scale automated switchgear and thus affect the emergency dispatch capability of the power grid. By combining passive signal detection and comparison function and active remote control preset management function, the management of remote control function of automated switchgear is made complementary, further strengthening the control of remote control function of automated switchgear.

[0172] Please see Figure 4 , Figure 4 This is a structural block diagram of a remote control function monitoring device for an automated switch provided in Embodiment 3 of the present invention.

[0173] This invention provides a remote control function monitoring device for automated switches, applied to a power grid remote control function management system. The power grid remote control function management system includes multiple automated switchgear and a communication terminal. The multiple automated switchgear are communicatively connected to the communication terminal, including:

[0174] The response module 301 is used to respond to the received monitoring request information, determine the target automated switching equipment corresponding to the monitoring request information, and obtain the first remote signaling data corresponding to the communication terminal.

[0175] The comparison module 302 is used to compare the first remote signaling data with the preset first threshold data.

[0176] The first data processing module 303 is used to determine the target result by using the return signal data to determine whether the active function is missing if the first remote signaling data is less than the preset first threshold data.

[0177] The second data processing module 304 is used to determine the target result based on the second remote signaling data and the return signal data corresponding to the automated switching equipment if the first remote signaling data is greater than or equal to the preset first threshold data.

[0178] Furthermore, the response module 301 includes:

[0179] The target automated switchgear determination submodule is used to determine the target automated switchgear corresponding to the received monitoring request information in response to the monitoring request information.

[0180] The online time acquisition submodule is used to obtain the online time of the communication terminal within a unit of time.

[0181] The calculation submodule is used to perform calculations based on online time and unit time to generate the corresponding first remote signaling data;

[0182] Among them, the first remote signaling data is the online rate of the communication terminal within a unit of time;

[0183] The formula for calculating the first remote information data is:

[0184]

[0185] In the formula, S represents the first remote signaling data, T represents the online time, and T0 represents the online time. S Indicates a unit of time.

[0186] Furthermore, the second data processing module 304 includes:

[0187] The data acquisition submodule is used to acquire the second remote signaling data and the return signal data corresponding to the automated switching equipment if the first remote signaling data is greater than or equal to the preset first threshold data.

[0188] The second remote signaling data includes energy storage status data, SF6 abnormal signal data, terminal device fault data, lockout closing signal data, lockout opening signal data, or disconnector status data.

[0189] The first determination submodule is used to analyze the second remote signaling data. When any of the following defect types exist: energy storage abnormality defect, SF6 abnormality defect, terminal device failure defect, lockout closing defect, lockout opening defect, or switch in cold standby state defect, the target result is determined to be remote control function missing.

[0190] The second determination submodule is used to determine whether the active function is missing when there is a local state defect by using the return signal data. If the active function is missing, the target result is determined to be a missing remote control function.

[0191] The third determination submodule is used to determine whether the active function is missing when there is no defect type associated with the second remote signaling data. If the active function is missing, the target result is determined to be a missing remote control function.

[0192] Furthermore, determining whether there is a deficiency in active functions specifically involves:

[0193] The number of failures associated with the return-to-cathode signal data that was not fed back by the target automated switching equipment within a preset time period;

[0194] When the number of failures exceeds the preset failure threshold for remote control, it is determined that the active function is missing, and the target result is determined to be a missing remote control function.

[0195] Furthermore, it also includes:

[0196] The success count module is used to count the number of successful correlations between the return signal data fed back by the target automated switchgear within a preset time period if the target result is that the remote control function is missing and the active function is missing.

[0197] The update module is used to update the target result if the number of successful attempts exceeds the preset recovery threshold of the remote control.

[0198] Furthermore, it also includes:

[0199] The unplanned remote control function missing module is used when the first remote signaling data is less than the preset first threshold data and the active function is missing;

[0200] Alternatively, there may be abnormal defects in energy storage and a lack of active functions;

[0201] Alternatively, there may be an SF6 anomaly defect and a lack of active functionality;

[0202] Alternatively, if there is a terminal device malfunction or defect and the active function is missing, the target automated switchgear is determined to have an unplanned remote control function deficiency and an alarm signal is output.

[0203] A module for missing planned remote control functions is used when there are defects in the local status and the active functions are missing.

[0204] Or, a defect in the locking and closing mechanism and an active function;

[0205] Or, the circuit breaker has a lockout tripping defect and an active function;

[0206] Alternatively, if the switch is in a cold standby state with a defect but has active functionality, the target automated switchgear is determined to have a planned remote control function deficiency and is marked accordingly.

[0207] In this invention, in response to a received monitoring request, the target automated switchgear corresponding to the monitoring request is identified, and the first remote signaling data corresponding to the communication terminal is acquired. The first remote signaling data is compared with a preset first threshold data. If the first remote signaling data is less than the preset first threshold data, the target result is determined by using return-to-calibration signal data to determine whether there is a missing active function. If the first remote signaling data is greater than or equal to the preset first threshold data, the target result is determined based on the second remote signaling data and return-to-calibration signal data corresponding to the automated switchgear. This invention solves the problems of current remote control methods, such as the inability to detect remote control function defects in a timely manner, slow control speed, and high labor costs, which make it difficult to meet the operation and control of large-scale automated switchgear and thus affect the emergency dispatch capability of the power grid. By combining passive signal detection and comparison function and active remote control preset management function, the management of remote control function of automated switchgear is made complementary, further strengthening the control of remote control function of automated switchgear.
