Description

Technical Field

[0001] The present disclosure relates to the technical field of relay protection, and in particular to a method, device, equipment and medium for automatic switching of relay protection fixed values. Background Art

[0002] A relay protection device is an automatic, emergency-preventing device installed on key components of the power supply and distribution system. It responds quickly and accurately to various faults or abnormal operating conditions within a specified area, tripping the circuit breaker or issuing a signal within a specified timeframe. During normal operation, the relay protection device remains inactive, closely monitoring the operating status of the system and its components in real time. Should a fault or abnormal operating condition occur, the relay protection device rapidly activates, isolates the fault, and issues an alarm, safeguarding the safety of the power supply and distribution system. Therefore, it plays a vital role in ensuring safe system operation, ensuring power quality, and preventing fault escalation and accidents. The relay protection setting is key to the correct operation of the relay protection device and plays a crucial role in ensuring the safe, stable, and reliable operation of the power supply and distribution system, directly impacting the safety of electrical equipment and the continuity of power supply.

[0003] When the two power supply lines of the power supply and distribution system are one main and one auxiliary, during normal operation, one power supply line is the main power supply, which is responsible for supplying power to all loads in the entire system. Only when the main power supply is short-circuited or outages occur for maintenance, the auxiliary power supply serves as the temporary main power supply. In this case, the main power supply generally has a high voltage level, large capacity, and high reliability, while the auxiliary power supply has a low voltage level, small capacity, and low reliability. Due to the large difference in voltage levels of the main and auxiliary power supplies (the main power supply voltage is generally 110kV and above, and the auxiliary power supply voltage is generally 10kV), the system impedance is quite different. When the operating mode of the power supply and distribution system changes, the relay protection setting needs to be switched, otherwise the safe operation of the power supply and distribution system cannot be guaranteed.

[0004] In related technologies, relay protection devices cannot automatically switch relay protection settings as the operating mode of the power supply and distribution system changes. Manual operations such as power outage, manual switching of settings, and power supply are required, resulting in long power outages and the risk of misoperation. Summary of the Invention

[0005] The present disclosure aims to solve one of the technical problems in the related art at least to a certain extent.

[0019] The fifth embodiment of the present disclosure proposes a computer program product.

[0020] The present disclosure provides a method, device, computer equipment and storage medium for automatic switching of relay protection constants.

[0030] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present disclosure and are not to be construed as limiting the present disclosure.

[0031] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.) and signals involved in this disclosure are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of relevant countries and regions.

[0032] Figure 1 It is a flow chart of a method for automatic switching of relay protection settings proposed in one embodiment of the present disclosure.

[0033] Among them, it should be noted that the executor of the relay protection setting automatic switching method of this embodiment is the relay protection setting automatic switching device, which can be implemented by software and / or hardware. The device can be configured in a computer device, and the computer device can include but is not limited to a terminal, a server, etc. For example, the terminal can be a mobile phone, a handheld computer, etc.

[0034] like Figure 1 As shown, the relay protection setting automatic switching method includes:

[0035] S101: Determine the current set value information and switch status information of the target power supply and distribution system, wherein the target power supply and distribution system includes a first switch and at least one second switch, the first switch is used to control the power status between the auxiliary power supply and the power-consuming equipment, and the second switch is used to control the power status between the main power supply and the corresponding power-consuming equipment.

[0036] The target power supply and distribution system may refer to the power supply and distribution system for which the relay protection setting value automatic switching is to be performed in the embodiment of the present disclosure. The type of the target power supply and distribution system is not limited in the embodiment of the present disclosure.

[0037] The current setting information may refer to the relay protection setting currently used by the target power supply and distribution system.

[0038] The switch status information may be used to indicate the status of switches related to power switching in the target power supply and distribution system.

[0039] The first switch may be a switch for controlling the power supply between the auxiliary power supply and the power-consuming device, while the second switch may be a switch for controlling the power supply between the main power supply and the corresponding power-consuming device.

[0040] In the embodiment of the present disclosure, when the current set value information and switch status information of the target power supply and distribution system are determined, reliable data support can be provided for the subsequent determination of the current operation mode and target operation mode of the target power supply and distribution system.

[0041] S102: Determine the current operating mode of the target power supply and distribution system based on the current set value information.

[0042] The current operation mode may be, for example, a main power supply operation or an auxiliary power supply operation.

[0043] It is understandable that when the target power supply and distribution system is in different operating modes, the corresponding relay protection settings may be different. Therefore, in the embodiment of the present disclosure, the current operating mode of the target power supply and distribution system can be determined based on the current setting information.

[0044] Optionally, in some embodiments, when determining the current operating mode of the target power supply and distribution system based on the current fixed value information, it may be that when the current fixed value information indicates that the target power supply and distribution system is operating based on the first fixed value range, the current operating mode of the target power supply and distribution system is determined to be the normal power supply operating mode; when the current fixed value information indicates that the target power supply and distribution system is operating based on the second fixed value range, the current operating mode of the target power supply and distribution system is determined to be the emergency power supply operating mode. In this way, the current operating mode of the target power supply and distribution system can be quickly determined, thereby effectively improving the fixed value switching efficiency.

[0045] A fixed value zone refers to an independent area within a relay protection device used to store multiple sets of fixed values. Users can switch between different fixed value groups based on the operating mode or system status. The fixed value types within a fixed value zone may include current, voltage, time, impedance, and direction, without limitation. The first and second fixed value zones may refer to two pre-selected fixed value zones configured within the relay protection setting system for different operating modes.

[0046] The normal power supply operation mode may refer to a working mode in which the main power supply is used for normal power supply, while the emergency power supply operation mode may refer to a working mode in which the auxiliary power supply is used for temporary power supply.

[0047] In the embodiment of the present disclosure, when the current operating mode of the target power supply and distribution system is determined based on the current set value information, an accurate analysis of the current operating mode of the target power supply and distribution system can be achieved, thereby providing reliable reference information for subsequent determination of whether relay protection set value switching is required.

[0048] S103: Determine a target operating mode of the target power supply and distribution system according to the switch status information.

[0049] The target operation mode may refer to the operation mode that the target power supply and distribution system needs to switch to, such as a normal power supply operation mode or an emergency power supply operation mode, without limitation.

[0050] Optionally, in some embodiments, when determining the target operating mode of the target power supply and distribution system based on the switch status information, the target operating mode of the target power supply and distribution system may be determined to be the normal power supply mode when one of the at least one second switch is in the closed state; and the target operating mode of the target power supply and distribution system may be determined to be the emergency power supply mode when each second switch is in the open state and the first switch is in the closed state. In this way, the target operating mode can be accurately determined by combining the states of the first and second switches, thereby ensuring the reliability of the resulting target operating mode.

[0051] S104: When the current operation mode is different from the target operation mode, the relay protection setting system switches the relay protection setting.

[0052] Optionally, in some embodiments, the relay protection setting system includes at least:

[0053] A first fixed value area, wherein the first fixed value area includes a first time fixed value and a first current fixed value;

[0054] The second fixed value area includes a second time fixed value and a second current fixed value.

[0055] In this way, the practicality of the target power supply and distribution systems corresponding to the first fixed value area and the second fixed value area can be effectively improved.

[0056] The time setting value may refer to the delay action time (e.g., 0.5 seconds). The first time setting value may refer to the time setting value configured for the normal power supply operation mode. The second time setting value may refer to the time setting value configured for the emergency power supply operation mode.

[0057] The current setting value may refer to the activation threshold of the current protection. The first current setting value may refer to the current setting value configured for the normal power supply operation mode. The second current setting value may refer to the current setting value configured for the emergency power supply operation mode.

[0058] Optionally, in some embodiments, when the current operating mode is the normal power supply mode and the target operating mode is the emergency power supply mode, the operating setting range of the relay protection setting system can be switched from the first setting range to the second setting range. This allows for automatic switching of the relay protection setting during the transition from the normal power supply mode to the emergency power supply mode.

[0059] Optionally, in some embodiments, when the current operating mode is the emergency power supply mode and the target operating mode is the normal power supply mode, the operating setting range of the relay protection setting system may be switched from the second setting range to the first setting range. This allows for automatic switching of the relay protection setting during the transition from the emergency power supply mode to the normal power supply mode.

[0060] In this embodiment, by determining the current set value information and switch status information of the target power supply and distribution system, wherein the target power supply and distribution system includes a first switch and at least one second switch, the first switch is used to control the power-on status between the auxiliary power supply and the power-consuming equipment, and the second switch is used to control the power-on status between the main power supply and the corresponding power-consuming equipment; based on the current set value information, the current operating mode of the target power supply and distribution system is determined; based on the switch status information, the target operating mode of the target power supply and distribution system is determined; when the current operating mode is different from the target operating mode, the relay protection set value system performs relay protection set value switching. In this way, automatic switching of relay protection set values ​​can be achieved, effectively shortening the power outage time, thereby effectively improving the safety and reliability of the power system.

[0061] It is understandable that when the two power lines of the power supply and distribution system are in a primary and secondary relationship, during normal operation, Figure 2 As shown, Figure 2 This is a schematic diagram of the normal power supply mode of the power supply and distribution system proposed in this disclosure, in which one power line is the main power source, which is responsible for supplying power to all loads in the entire system. Only when the main power source is short-circuited or out of power for maintenance, the auxiliary power source will serve as the temporary main power source, such as Figure 3 As shown, Figure 3 This is a schematic diagram of emergency power supply for the power supply and distribution system proposed in the present invention. In this case, the main power supply generally has a high voltage level, large capacity, and high reliability, while the auxiliary power supply has a low voltage level, small capacity, and low reliability. In this case, due to the large difference in the voltage levels of the main and auxiliary power supplies (the main power supply voltage is generally 110kV and above, and the auxiliary power supply voltage is generally 10kV), the system impedance difference is large. When the operating mode of the power supply and distribution system changes, the relay protection setting needs to be switched, otherwise the safe operation of the power supply and distribution system cannot be guaranteed. The existing relay protection device cannot automatically switch the relay protection setting as the operating mode of the power supply and distribution system changes. Manual operations such as power outage, manual switching of the setting, and power supply are required. The power outage time of this solution is long and there is a risk of misoperation.

[0062] In summary of the above embodiments, the present invention proposes a relay protection setting value automatic switching system and method, by integrating the relay protection setting value automatic switching function into the plant power monitoring and management system (ECMS), such as Figure 4 As shown, Figure 4 This is a simplified diagram of the ECMS system structure proposed in the present disclosure. Without adding equipment and cable wiring, it realizes the automatic switching of relay protection settings as the system operating mode changes, thereby improving the automation level of the power supply and distribution system.

[0063] The principle of the relay protection setting automatic switching system is as follows:

[0064] Step 1: If Figure 2 、 3 As shown, the relay protection device stores the relay protection setting value in the normal operation mode in the setting value area 1 (i.e., the first setting value area mentioned above), and stores the relay protection setting value in the emergency mode in the setting value area 2 (i.e., the second setting value area mentioned above). Switch 2 (i.e., the first switch mentioned above) and switches 3 and 4 (i.e., the second switches mentioned above) have an interlocking function.

[0065] Step 2: When the power supply is 220kV bus (normal operation mode), switch 2 is open, switch 3 or switch 4 is closed, and the setting zone 1 in the relay protection device is activated to protect the safe operation of the system and equipment;

[0066] Step 3: When the 220kV power supply fails and the power is supplied by the 10kV line outside the factory through the security isolation transformer, switch 2 is closed and switches 3 and 4 are opened. The integrated protection and measurement and control device detects the status changes of switches 2, 3, and 4, and uploads the status change information to the station control layer through the intelligent bay layer and communication management layer, notifying the monitoring personnel that the system operation mode has changed and switching the relay protection settings of the corresponding electrical equipment;

[0067] Step 4: After the relay protection setting automatic switching system receives the key switch state change information, it automatically issues a relay protection setting switching instruction. The instruction is transmitted to the integrated protection measurement and control device of the corresponding electrical equipment through the communication management layer and the intelligent interval layer. After receiving the instruction, the integrated protection measurement and control device switches the setting in the relay protection device to the setting zone 2. At this time, the setting in the setting zone 2 takes effect to protect the safe operation of the protection system and equipment.

[0068] Step 5: End the process.

[0069] For example, if Figure 5 As shown, Figure 5 It is a working flow chart of the relay protection fixed value automatic switching system proposed in this disclosure.

[0070] This technical invention realizes that the relay protection device automatically switches the relay protection setting value as the operating mode of the power supply and distribution system changes, reducing the manual operations of the entire system such as power outage, manual switching of setting values, and power supply when the system power supply is switched under the existing mode. With the help of the existing plant power monitoring and management system (ECMS) system architecture of the power supply and distribution system, the automatic switching function of the relay protection setting value is integrated into the ECMS system. The comprehensive protection measurement and control device detects the opening and closing status of key switches and uploads relevant information to the station control layer through the intelligent interval layer and the communication management layer. Electrical engineers can view the operating status of the relay protection setting value automatic switching system in real time at the electrical engineer station. The relay protection setting value automatic switching system is integrated in the ECMS system, and relies on the ECMS system to automatically transmit the switching instruction to the comprehensive protection measurement and control device of the relevant equipment. After receiving the relay protection setting value switching command, the comprehensive protection measurement and control device switches the setting value in the relay protection device to make the relay protection setting value adapt to the system operating mode, realizing the automatic switching of the relay protection setting value and improving the automation level of the plant power supply and distribution system.

[0071] The advantages of the present invention are as follows:

[0072] 1. The integrated protection and measurement and control device automatically detects the opening and closing positions of key switches. By integrating the automatic switching function of relay protection settings into the plant power monitoring and management system (ECMS), the relay protection settings can be automatically switched as the system operating mode changes without adding additional equipment or cabling.

[0073] 2. When the operating mode of the power supply and distribution system of the plant changes, the relay protection setting value can be automatically switched through the plant power monitoring and management system (ECMS), reducing the manual operations such as power outage, manual switching of setting values, and power supply under the existing switching mode, thereby improving the automation level of the power supply and distribution system.

[0074] Figure 6 It is a structural diagram of a relay protection fixed value automatic switching device proposed in one embodiment of the present disclosure.

[0075] like Figure 6 As shown, the relay protection fixed value automatic switching device 60 includes:

[0076] A first determining module 601 is configured to determine current setting information and switch status information of a target power supply and distribution system, wherein the target power supply and distribution system includes a first switch and at least one second switch, the first switch being configured to control the power supply status between the auxiliary power source and the power-consuming device, and the second switch being configured to control the power supply status between the main power source and the corresponding power-consuming device;

[0077] A second determining module 602 is configured to determine a current operating mode of the target power supply and distribution system based on current set value information;

[0078] A third determining module 603 is configured to determine a target operating mode of the target power supply and distribution system according to the switch state information;

[0079] The switching module 604 is used to switch the relay protection setting value by the relay protection setting value system when the current operation mode is different from the target operation mode.

[0080] It should be noted that the above explanation of the automatic switching method of the relay protection setting is also applicable to the automatic switching device of the relay protection setting in this embodiment, and will not be repeated here.

[0081] In this embodiment, by determining the current set value information and switch status information of the target power supply and distribution system, wherein the target power supply and distribution system includes a first switch and at least one second switch, the first switch is used to control the power-on status between the auxiliary power supply and the power-consuming equipment, and the second switch is used to control the power-on status between the main power supply and the corresponding power-consuming equipment; based on the current set value information, the current operating mode of the target power supply and distribution system is determined; based on the switch status information, the target operating mode of the target power supply and distribution system is determined; when the current operating mode is different from the target operating mode, the relay protection set value system performs relay protection set value switching. In this way, automatic switching of relay protection set values ​​can be achieved, effectively shortening the power outage time, thereby effectively improving the safety and reliability of the power system.
