Description

Technical Field

[0001] The invention belongs to the technical field of remote opening and closing control, and relates to a remote opening / closing control system based on a special transformer terminal. Background Art

[0002] Remote opening / closing refers to the technology of opening or closing electrical equipment, such as circuit breakers and special transformer terminals, by remote control. Special transformer terminals are intelligent devices used in power systems, mainly used to monitor and control the operating status of special transformers. Through integrated data acquisition and communication functions, it can monitor various electrical parameters of the transformer in real time, and realize the opening and closing operations of the transformer through remote control. With the continuous development of power systems and the improvement of the level of intelligence, the demand for remote monitoring and operation of power equipment is increasing. As an important device for collecting and managing electricity consumption information of power users, the realization of remote opening / closing control function of special transformer terminals can significantly improve the automation level and operation efficiency of power systems and meet the development needs of modern power systems. Therefore, the control method of opening and closing based on special transformer terminals is of great significance and role.

[0003] In the prior art, there are also some related solutions involving opening and closing control, for example, the invention patent application for circuit breaker opening and closing control method, device and system with Chinese patent publication number CN111413910A, which determines the current load characteristics of the EMU according to the real-time voltage and real-time current when the acquired real-time voltage and real-time current reach the predetermined trigger condition, and then judges whether to perform the circuit breaker opening processing according to the inherent electrical characteristics of the operating section and the current load characteristics. When the judgment result is to perform the opening processing, the opening phase information is generated according to the real-time voltage and real-time current, and the circuit breaker is opened according to the opening phase information. When overvoltage and overcurrent occur, it can be timely judged whether to perform the opening processing to alleviate the overvoltage and overcurrent, thereby effectively reducing the impact of overvoltage and overcurrent on the EMU and the traction power supply system, and thus prolonging the life of the EMU and the traction power supply system.

[0004] Although the above schemes have proposed some solutions for the opening and closing control, there are still certain limitations: on the one hand, the existing schemes mainly determine the load characteristics based on the real-time voltage and real-time current of the equipment, and then compare them with the inherent load characteristics to determine whether to perform the opening operation. However, for the opening and closing control method of the dedicated transformer terminal, the existing schemes ignore the detection and analysis from multiple dimensions such as power anomalies, equipment operation and harsh environment, and thus cannot avoid the impact on the operation of the power grid due to equipment maintenance and harsh environment, and thus cannot guarantee the safety and stability of the power grid.

[0005] On the other hand, the existing scheme ignores the detection of the current state of the opening and closing switch, thereby failing to shorten the fault handling time and improve the operating efficiency of the opening and closing switch. It is also impossible to avoid detecting and analyzing the opening and closing switch when there is no need to change the opening and closing state, and thus failing to respond quickly to control. Summary of the invention

[0006] In view of this, in order to solve the problems raised in the above background technology, a remote opening / closing control system based on a dedicated transformer terminal is proposed.

[0007] The objective of the present invention can be achieved through the following technical scheme: The present invention provides a remote opening / closing control system based on a special transformer terminal, comprising: a remote opening / closing status acquisition module, a special transformer terminal detection and analysis module, a remote opening / closing opening control demand judgment module, a remote opening / closing control module, a remote opening / closing detection and analysis module and a cloud database.

[0008] The remote opening / closing status acquisition module is used to record each detected special transformer terminal as a designated special transformer terminal, record the remote opening / closing deployed at each designated special transformer terminal as a designated remote opening / closing, and obtain the status of each designated remote opening / closing, where the status includes the opening status and the closing status.

[0009] The dedicated transformer terminal detection and analysis module is used to perform real-time detection of the power, equipment and environment of each designated dedicated transformer terminal, obtain the power parameter data, equipment operation data and surrounding environment data of each designated dedicated transformer terminal, and analyze the power abnormality, equipment operation status and environmental conditions of each designated dedicated transformer terminal.

[0010] The remote opening / closing control demand judgment module is used to analyze the opening control demand of each designated remote opening / closing switch according to the power abnormality, equipment operation and environmental conditions of each designated special transformer terminal.

[0011] The remote opening / closing control module is used to record each designated remote opening / closing of the opening control demand that needs to be changed as each opening control remote opening / closing, and perform state change control on each opening control remote opening / closing.

[0012] The remote opening / closing detection and analysis module is used to detect the state change process of the remote opening / closing of each opening control, obtain the state change process data of the remote opening / closing of each opening control, and analyze the operation status of the remote opening / closing of each opening control.

[0013] The cloud database is used to store the standard voltage, standard current and standard power factor of each designated special transformer terminal, store the total operating life of the designated special transformer terminal, store the permitted overload times, permitted short circuit times and permitted maintenance times corresponding to the operating time of each designated special transformer terminal, store the permitted rainfall, permitted snowfall, permitted wind speed and permitted magnitude under conditions that do not affect the normal operation of the special transformer terminal, and store the response time threshold, data packet loss rate threshold and delay time threshold of remote opening / closing.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention analyzes the power anomalies, equipment operation conditions and environmental conditions of each designated special transformer terminal, and then analyzes the opening / closing control requirements of each designated remote opening / closing switch based on this, and performs detection and analysis from multiple dimensions such as power anomalies, equipment operation and environmental conditions, which is conducive to avoiding the impact of equipment maintenance and harsh environment on the operation of the power grid, and thus helps to ensure the safety and stability of the power grid.

[0015] 2. The present invention obtains the state of remote opening / closing of each opening switch control and performs opening control on each opening switch control remote opening / closing, thereby avoiding the processing time on the remote opening / closing of each opening switch control that does not need opening control, which is beneficial to shorten the processing time and help to improve the operating efficiency of remote opening / closing.

[0016] 3. The present invention obtains the state change process data of each branch switch controlling the remote opening / closing, analyzes the operation status of each branch switch controlling the remote opening / closing, helps to identify bottlenecks or potential problems in the remote opening / closing communication network, and takes corresponding optimization measures, thereby facilitating the rapid response control of the remote opening / closing and ensuring the accuracy and reliability of the remote opening / closing operation.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1 As shown, the present invention provides a remote opening / closing control system based on a special transformer terminal, and the specific modules are distributed as follows: a remote opening / closing state acquisition module, a special transformer terminal detection and analysis module, a remote opening / closing control demand judgment module, a remote opening / closing control module, a remote opening / closing detection and analysis module, and a cloud database. The remote opening / closing state acquisition module is connected to the special transformer terminal detection and analysis module, the special transformer terminal detection and analysis module is connected to the remote opening / closing control demand judgment module, the remote opening / closing control demand judgment module is connected to the remote opening / closing control module, the remote opening / closing control module is connected to the remote opening / closing detection and analysis module, and the cloud database is respectively connected to the special transformer terminal detection and analysis module and the remote opening / closing detection and analysis module.

[0022] The remote opening / closing status acquisition module is used to record each detected special transformer terminal as a designated special transformer terminal, record the remote opening / closing deployed at each designated special transformer terminal as a designated remote opening / closing, and obtain the status of each designated remote opening / closing, where the status includes the opening status and the closing status.

[0023] It needs to be further explained that the open state is a state in which the circuit is disconnected, and the closed state is a state in which the circuit is closed.

[0024] As a preferred feasibility example, the power parameter data of each designated dedicated transformer terminal includes voltage, current and power factor.

[0025] It is necessary to further explain that the reason why voltage, current and power factor are used as the power parameter data of each designated special transformer terminal is that voltage is one of the important indicators of power quality. It reflects the power level supplied by the power system to users and is crucial to the normal operation of power equipment. Too high or too low voltage may cause damage to power equipment and affect the performance and life of the equipment. Therefore, monitoring voltage can ensure that the power system operates stably within the specified voltage range and protect the safety of power equipment.

[0026] Current is the carrier of electric energy transmission. Its size directly reflects the flow of electric energy in the power system. Monitoring current can understand the load of electrical equipment and determine whether the equipment is in normal working condition. In the power system, abnormal fluctuations in current may indicate equipment failure or system instability. Therefore, timely monitoring of current is of great significance for preventing accidents and ensuring system safety.

[0027] Power factor is an important indicator to measure the energy efficiency of electrical equipment. It reflects the proportional relationship between active power and apparent power. A low power factor means that the electrical equipment generates less useful power and more ineffective power when consuming the same amount of electricity, which will not only increase the loss of the power grid, but also reduce the power supply capacity of the power grid.

[0028] It needs to be further explained that the specific method of obtaining the voltage, current and power factor of each designated special transformer terminal is: directly extracting the voltage, current and power factor of each designated special transformer terminal from the metering meter of each designated special transformer terminal.

[0029] The equipment operation data of each designated dedicated transformer terminal includes operation time, overload times, short circuit times and maintenance times.

[0030] It needs to be further explained that the reason for using operating hours, overload times, short circuit times and maintenance times as the equipment operation data of each designated special transformer terminal is that operating hours are an important indicator for evaluating the service life of equipment. By recording the operating time of the equipment, the degree of aging of the equipment can be understood, providing a scientific basis for equipment maintenance and replacement.

[0031] The number of overload times reflects the operation of the equipment under overload conditions. Frequent overloads may cause equipment damage, performance degradation and other problems. Therefore, monitoring the number of overload times helps to promptly detect and solve the problem of excessive load.

[0032] Short circuit failures are usually related to the insulation performance of the equipment. Recording the number of short circuits can reflect the insulation condition of the equipment and provide a basis for equipment maintenance and inspection.

[0033] The number of maintenance times directly reflects the maintenance status of the equipment. By recording the number of maintenance times, we can understand the maintenance frequency and quality of the equipment, and provide a basis for formulating a more reasonable maintenance plan.

[0034] It needs to be further explained that the specific method of obtaining the operating hours, overload times, short circuit times and maintenance times of each designated special transformer terminal is: directly extracting the operating hours, overload times, short circuit times and maintenance times of each designated special transformer terminal from the maintenance record table of each designated special transformer terminal.

[0035] The surrounding environment data of each designated dedicated transformer terminal includes rainfall, snowfall, wind speed and magnitude.

[0036] It is necessary to further explain that the reason for using rainfall, snowfall, wind speed and earthquake magnitude as the surrounding environment data of each designated special transformer terminal is that heavy rain or rainstorms are likely to cause natural disasters such as floods and mudslides, which will have a serious impact on the normal operation of the power system. By monitoring rainfall, timely warnings can be issued and corresponding disaster prevention measures can be taken to reduce the impact of disasters on the power system.

[0037] Excessive snowfall may cause snow to cover power equipment, affecting the heat dissipation and normal operation of the equipment. At the same time, snow may also break tree branches and wires, causing equipment damage or power outages. By monitoring snowfall, snow can be cleared in time to ensure equipment safety.

[0038] Strong winds may cause accidents such as power lines swaying, towers tilting or even collapsing, which seriously affect the safe operation of the power system. By monitoring wind speed, we can assess the degree to which equipment is affected by wind pressure and take reinforcement measures in time to ensure equipment safety. Strong winds may also trigger natural disasters such as sandstorms and tornadoes, which can have a devastating impact on the power system. Monitoring wind speed helps to provide timely warnings and take appropriate disaster prevention measures to reduce disaster losses.

[0039] Earthquakes are one of the major natural disasters faced by power systems. By monitoring the magnitude of earthquakes, we can assess the extent of damage to power equipment caused by earthquakes, and provide a scientific basis for post-disaster repair and power restoration. After an earthquake, the power system may suffer serious damage, resulting in large-scale power outages. Monitoring the magnitude of earthquakes helps to quickly launch emergency plans, organize repair teams and deploy materials, and restore power supply as soon as possible.

[0040] It needs to be further explained that the specific method of obtaining the rainfall, snowfall, wind speed and magnitude of each designated special transformer terminal is: directly extracting the rainfall, snowfall, wind speed and magnitude of each designated special transformer terminal from the meteorological center where each designated special transformer terminal is located.

[0041] As a preferred feasibility example, the specific acquisition method of the states of each designated remote opening / closing switch is as follows: extract the current and voltage at both ends of each designated dedicated transformer terminal, which are recorded as ,in , It is the number of each designated special transformer terminal. The number of designated dedicated transformer terminals.

[0042] It needs to be further explained that the specific method of obtaining the current and voltage at both ends of each designated special transformer terminal is: using the deployed current transformer and voltage transformer to measure and obtain the current and voltage at both ends of each designated special transformer terminal.

[0043] According to the analytical formula Get the status representative value of each designated remote opening / closing ,in They are and conform to the and or symbols, Indicates The state of the specified remote opening / closing is the closing state. Indicates The state of a specified remote opening / closing is the opening state.

[0044] The dedicated transformer terminal detection and analysis module is used to perform real-time detection of the power, equipment and environment of each designated dedicated transformer terminal, obtain the power parameter data, equipment operation data and surrounding environment data of each designated dedicated transformer terminal, and analyze the power abnormality, equipment operation status and environmental conditions of each designated dedicated transformer terminal.

[0045] As a preferred feasibility example, the specific analysis method of the power abnormality of each designated dedicated transformer terminal includes: extracting the voltage, current and power factor of each designated dedicated transformer terminal, which are recorded as ,in , It is the number of each designated special transformer terminal. Analyze the power anomaly indicators of each designated dedicated transformer terminal for the designated dedicated transformer terminal ,in is a natural constant, They are extracted from the cloud database. The standard voltage, standard current and standard power factor of a specified special transformer terminal are They are the allowable difference between the set voltage and the standard voltage, the allowable difference between the current and the standard current, and the allowable difference between the power factor and the standard power factor.

[0046] Exemplarily, the set allowable difference between the voltage and the standard voltage, the set allowable difference between the current and the standard current, and the set allowable difference between the power factor and the standard power factor can be set to 0.01, 0.01, and 0.001, respectively.

[0047] It should be further explained that voltage deviation is a common phenomenon in power grid operation, but excessive deviation will affect the normal operation of power equipment. Setting the allowable difference between voltage and standard voltage to 0.01 means that voltage fluctuation within ±1% is acceptable, which helps to ensure that the power grid operates within a stable range and avoid damage to equipment caused by excessive voltage fluctuations.

[0048] Excessive current may cause equipment overheating, damage, or even fire and other safety accidents. Setting the current tolerance to 0.01 means that current fluctuations within ±1% are acceptable, which helps to promptly detect and handle current anomalies, protect the safety of power equipment, and improve the operating efficiency and stability of the power grid.

[0049] The power factor reflects the ratio of useful power to reactive power in a circuit. The higher the power factor, the higher the efficiency of electric energy use. Moreover, the maximum value of the power factor is 1. Therefore, setting the allowable difference of the power factor to 0.001 means that the power factor fluctuation within ±0.1% is acceptable, which helps to motivate users to take measures to improve the power factor, thereby reducing the consumption of reactive power and improving the efficiency of electric energy use. In addition, a high power factor can reduce the reactive current in the power grid, thereby reducing the line loss and transformer loss of the power grid and improving the economic benefits of the power grid.

[0050] The power anomaly index of each designated special transformer terminal is compared with the set power anomaly index threshold. If the power anomaly index of a designated special transformer terminal is greater than the power anomaly index threshold, the power anomaly situation of the designated special transformer terminal is recorded as the existence of power anomaly. Otherwise, the power anomaly situation of the designated special transformer terminal is recorded as the absence of power anomaly.

[0051] As a preferred feasibility example, the specific analysis method of the equipment operation status of each designated dedicated transformer terminal includes: extracting the operation time, overload times, short circuit times and maintenance times of each designated dedicated transformer terminal, and recording them as , analyze the abnormal operation indicators of each designated dedicated transformer terminal ,in is the total operating life of the specified dedicated transformer terminal extracted from the cloud database. They are extracted from the cloud database. The permitted number of overload times, permitted number of short circuit times and permitted number of maintenance times corresponding to the operating time of a specified dedicated transformer terminal.

[0052] The equipment operation abnormality index of each designated special transformer terminal is compared with the set equipment operation abnormality index threshold. If the equipment operation abnormality index of a designated special transformer terminal is greater than the equipment operation abnormality index threshold, the equipment operation status of the designated special transformer terminal is recorded as equipment operation abnormality; otherwise, the equipment operation status of the designated special transformer terminal is recorded as equipment operation normal.

[0053] As a preferred feasibility example, the environmental conditions of each designated special transformer terminal are specifically analyzed in the following manner: extracting the rainfall, snowfall, wind speed and magnitude of the surrounding environment of each designated special transformer terminal, and recording them as , analyze the environmental abnormality indicators of each designated special transformer terminal ,in They are respectively the allowable rainfall, allowable snowfall, allowable wind speed and allowable magnitude extracted from the cloud database without affecting the normal operation of the dedicated transformer terminal.

[0054] The environmental abnormality index of each designated special transformer terminal is compared with the set environmental abnormality index threshold. If the environmental abnormality index of a designated special transformer terminal is greater than the environmental abnormality index threshold, the environmental condition of the designated special transformer terminal is recorded as environmental abnormality. Otherwise, the environmental condition of the designated special transformer terminal is recorded as normal.

[0055] The remote opening / closing control demand judgment module is used to analyze the opening control demand of each designated remote opening / closing switch according to the power abnormality, equipment operation and environmental conditions of each designated special transformer terminal.

[0056] As a preferred feasibility example, the specific analysis method of the opening / closing control requirements of each designated remote opening / closing switch includes: extracting the power abnormality, equipment operation status and environmental conditions of each designated special transformer terminal, and analyzing the abnormal power condition, equipment operation status and environmental conditions of each designated special transformer terminal according to the analysis model. Get the opening and closing control requirements of each designated remote opening / closing ,in Indicates that the opening control demand is no need for control demand. Indicates that the opening control demand is a required control demand. Indicates The power abnormality of the designated special transformer terminal is that there is no power abnormality. Indicates The equipment operation status of the designated dedicated transformer terminal is that the equipment is operating normally. Indicates The environment condition of the designated special transformer terminal is normal. Is a non-symbol.

[0057] The present invention analyzes the power anomalies, equipment operation conditions and environmental conditions of each designated special transformer terminal, and then analyzes the opening / closing control requirements of each designated remote opening / closing terminal based on this, and performs detection and analysis from multiple dimensions such as power anomalies, equipment operation and environmental conditions, which is helpful to avoid the impact of equipment maintenance and harsh environment on power grid operation, and thus helps to ensure the safety and stability of the power grid.

[0058] The remote opening / closing control module is used to record each designated remote opening / closing switch with an opening control demand as a remote opening / closing switch of each opening control, and perform opening control on each remote opening / closing switch of each opening control.

[0059] As a preferred feasibility example, the remote opening / closing control of each opening switch includes the following specific operations: S1, extracting the status of each designated remote opening / closing switch, filtering out the status of each opening switch control remote opening / closing switch, further filtering out each opening switch control remote opening / closing switch in the closed state, and recording them as each marked remote opening / closing switch.

[0060] S2. In the remote control center, the operator uses the communication network to send the opening command to each tag for remote opening / closing.

[0061] S3. After receiving the command, each remote opening / closing tag performs the opening operation according to the command content. After completing the operation, each remote opening / closing tag feeds back the operation result to the remote control center to confirm whether the opening is successfully executed.

[0062] It is necessary to further explain that the specific operation flow diagram of remote opening / closing of each opening switch is as follows: Figure 2 shown.

[0063] The present invention obtains the state of remote opening / closing of each opening switch control and performs opening control on each remote opening / closing of the opening switch control, thereby avoiding the processing time on the remote opening / closing of each opening switch control that does not need opening control, which is beneficial to shorten the processing time and help to improve the operating efficiency of remote opening / closing.

[0064] The remote opening / closing detection and analysis module is used to detect the state change process of the remote opening / closing of each opening control, obtain the state change process data of the remote opening / closing of each opening control, and analyze the operation status of the remote opening / closing of each opening control.

[0065] As a preferred feasibility example, the state change process data of each opening switch controlling remote opening / closing includes response time, data packet loss rate and delay time.

[0066] It needs to be further explained that the reason for using the response time, data packet loss rate and delay time as the state change process data of the remote opening / closing control of each opening / closing switch is that the response time directly reflects the response speed of the remote opening / closing control system to the state change request. A shorter response time means that the system can respond and execute operations quickly, thereby improving the flexibility and reliability of the power grid.

[0067] The packet loss rate is an important indicator to measure the quality of network communication. A low packet loss rate indicates that the network communication is stable and reliable, and can ensure the accurate transmission and execution of remote opening / closing instructions.

[0068] The delay time includes transmission delay time and processing delay time, which reflects the total time required for data to travel from the sender to the receiver. Low delay time means that the system can perform remote opening / closing operations in real time or near real time, reducing operational errors or failures caused by delay time.

[0069] It needs to be further explained that the specific method of obtaining the response time, data packet loss rate and delay time of each sub-switch controlling the remote opening / closing is: directly extracting the response time, data packet loss rate and delay time of each sub-switch controlling the remote opening / closing from the command execution data of the remote control center of the remote opening / closing.

[0070] As a preferred feasibility example, in the process of analyzing the operation status of each branch control remote opening / closing, it is necessary to construct the operation compliance coefficient of each branch control remote opening / closing. The specific analysis method includes: extracting the response time, data packet loss rate and delay time of each branch control remote opening / closing, respectively recorded as ,in , The number of each switch that controls remote opening / closing. Calculate the number of remote opening / closing control for the opening switch and analyze the operation compliance coefficient of each opening switch remote opening / closing control ,in They are the response time threshold, data packet loss rate threshold and delay time threshold of remote opening / closing extracted from the cloud database respectively.

[0071] As a preferred feasibility example, the operating conditions of the remote opening / closing of each sub-switch control are specifically analyzed as follows: the operating compliance coefficient of each sub-switch control remote opening / closing is compared with the set operating compliance coefficient threshold value; if the operating compliance coefficient of a sub-switch control remote opening / closing is less than the operating compliance coefficient threshold value, the operating condition of the remote opening / closing of the sub-switch control is recorded as abnormal operation; otherwise, the operating condition of the remote opening / closing of the sub-switch control is recorded as normal operation.

[0072] Then the operation status of each branch switch controlling remote opening / closing can be obtained, and its corresponding number can be fed back and processed.

[0073] It needs to be further explained that the specific measures for handling the remote opening / closing control of each sub-switch according to its operating conditions include: if the operating condition of the remote opening / closing control of a sub-switch is abnormal, all related remote operations should be stopped immediately to prevent the fault from expanding or causing more serious consequences, and the maintenance personnel should be notified to conduct on-site inspections to confirm the actual status of the equipment.

[0074] Specifically, the on-site inspection includes: (1) Checking the power supply system: checking whether the power supply contactor is energized, whether the power supply of the distribution room cabinet is normal, and whether the remote operation components are faulty.

[0075] (2) Check the communication system: Confirm whether the remote operation command is successfully sent to the target device and whether the device receives the correct command. At the same time, check whether there is any fault or interference in the communication line.

[0076] (3) Check fault records: Check the fault records or system logs of the device, and analyze the operation records and status changes before and after the fault occurs to quickly locate the cause of the fault.

[0077] The cloud database is used to store the standard voltage, standard current and standard power factor of each designated special transformer terminal, store the total operating life of the designated special transformer terminal, store the permitted overload times, permitted short circuit times and permitted maintenance times corresponding to the operating time of each designated special transformer terminal, store the permitted rainfall, permitted snowfall, permitted wind speed and permitted magnitude under conditions that do not affect the normal operation of the special transformer terminal, and store the response time threshold, data packet loss rate threshold and delay time threshold of remote opening / closing.

[0078] The present invention obtains the state change process data of each opening / closing control remote opening / closing, analyzes the operation status of each opening / closing control remote opening / closing, helps to identify bottlenecks or potential problems in the remote opening / closing communication network, and takes corresponding optimization measures, thereby facilitating rapid response control of remote opening / closing and ensuring the accuracy and reliability of remote opening / closing operations.

[0079] The above contents are merely examples and explanations of the concept of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they shall all fall within the protection scope of the present invention.
