Background Art

[0002] The stabilization control device (system) is the second line of defense to ensure the safety and stability of the power system. The failure of the stabilization control device to operate may cause the stability of the power grid to be damaged, and even cause a large-scale power outage. The failure of the stabilization control device to operate has been the primary risk in the operation of the power grid over the years. The switch transmission of the stabilization control device is an important measure to prevent the failure of the stabilization control device to operate.

[0053] The embodiments of the present invention provide a non-stop transmission method suitable for a stabilization and control device, a non-stop transmission device suitable for a stabilization and control device, an electronic device and a storage medium, which are used to solve or partially solve the current problems of long export transmission verification period, low efficiency and heavy operating workload.

[0054] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below 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.

[0055] As an example, the existing stabilization and control devices are constrained by functions and secondary circuits. Since the standard configuration has 16 load shedding outlets, the export transmission requires load interval power outages and cannot be shut down at multiple intervals at one time, resulting in a long verification period for all exports and low efficiency. The existing export transmission verification method not only easily leads to a large workload for on-site operation and maintenance personnel to shut down power, but also brings risks to the power grid caused by equipment power outages. At present, there is no effective technical solution for remote non-stop transmission of stabilization and control devices.

[0056] Therefore, one of the core inventive points of the embodiment of the present invention is: in view of the shortcomings of the current technology, a non-stop transmission system and method suitable for conventional stabilizing and controlling devices is proposed. By means of external device access, the non-stop transmission system integrating multiple different functional modules is connected to the closing circuit of the load interval, and at the same time, the load shedding outlet circuit of the stabilizing and controlling device is connected and monitored in real time. After confirming the load shedding outlet of the stabilizing and controlling device, the system issues a closing outlet command corresponding to the load interval to realize the non-stop transmission of the stabilizing and controlling device. Thereby, not only the efficiency of the transmission test of the stabilizing and controlling device outlet can be effectively improved, but also the reliability of the power grid operation can be greatly improved, and a reliable stabilizing and controlling anti-refusal system can be constructed. In addition, the non-stop transmission system is integrated in a mobile box, and the test personnel can carry it to any substation. Therefore, it does not need to be fixedly installed in the substation panel cabinet, which is convenient to use, has high utilization rate and simple operation, and can greatly reduce the operating workload.

[0057] Reference Figure 1 , showing a structural schematic diagram of a non-stop power transmission system suitable for a stabilization control device provided by an embodiment of the present invention.

[0058] Combination Figure 1 The non-stop power transmission system 100 may mainly include an information processing and storage module 101, a receiving module 102, an export module 103 and an interaction module 104 respectively connected to the information processing and storage module 101.

[0059] The receiving module 102 refers to a module of the non-stop power transmission system 100 for receiving external electrical quantity input (ie, external electrical information). The external electrical quantity may mainly include the action contact of the stabilizing control device, the load shedding outlet contact of the stabilizing control device, and the system test pressure plate status.

[0060] The action contact of the stabilizing control device refers to the contact that is closed when the stabilizing control device performs load shedding action, and the state is open during normal operation. The load shedding outlet contact of the stabilizing control device refers to the contact that is closed when the stabilizing control device cuts off the corresponding load interval, and the state is open during normal operation. The system test pressure plate state refers to the pressure plate provided by the control panel of the non-stop power transmission system 100 for the test personnel to put in and withdraw. After successful investment, the display interface of the system will show that it is currently in the test state. When performing a non-stop power transmission test, the test state of the test pressure plate is put in, otherwise it is withdrawn.

[0061] The receiving module 102 sends the externally received information to the information processing and storage module 101 for further processing. The information processing and storage module 101 refers to a module of the non-stop transmission system 100 for processing, analyzing and storing information. The information processing and storage module 101 can analyze and process the external electrical quantity input, and based on the analysis and processing results, issue a closing instruction according to the closing outlet delay set by the test personnel. At the same time, the information processing and storage module 101 can also record the action status to provide the test personnel with inquiries. It can also store the closing outlet delay of each set load interval (hereinafter referred to as the set closing outlet delay) and the most recent action information.

[0062] That is to say, the information processing and storage module 101 can be mainly used to analyze and process electrical information, and based on the analysis and processing results, according to the set closing output delay transmitted from the interactive module 104, a closing instruction is issued to the output module 103, so that the output module 103 executes the closing output action.

[0063] After analyzing the exit logic criteria, the system (information processing and storage module 101) closes the corresponding load interval closing exit contact, and issues a closing command after setting the closing exit delay. The exit module 103 executes the closing exit action based on the closing command. The exit logic criteria refer to the following conditions being met at the same time: 1. The test pressure plate is put into operation; 2. The contact of the stabilizing control device action is closed; 3. The contact of the load shedding exit of the stabilizing control device is closed.

[0064] The interactive module 104 is mainly used to view instructions based on information input by the user, and to retrieve action messages from the information processing and storage module 101. Specifically, the interactive module 104 refers to an interface that provides test personnel with the ability to view action status and set the closing output delay. The action status refers to the timing message issued by the subsequent closure of the load-cutting output contact and the closing output instruction of the corresponding load branch interval, with the closure of the action contact of the stabilization and control device as the zero point, and is used to analyze whether the action status of the stabilization and control device is correct. The setting of the closing output delay refers to the delay time for issuing the closing command after the load-cutting output contact of each load interval is closed. Test personnel can make adjustments according to test needs.

[0065] In addition, the non-stop power transmission system 100 is also provided with an external hardware module. The external hardware module includes an anti-mistaken contact pin-type wiring, a liquid crystal module, a key button, a test hard pressure plate, a device box, etc. The external hardware module is similar to the external hardware and appearance of a common test instrument, and is not the key content to be protected by the technical solution of the present invention, and will not be described here.

[0066] In addition, the non-stop transmission system is integrated into a mobile box, which can be carried by testers to any substation. Therefore, it does not need to be fixedly installed in the substation cabinet. It is easy to use, has high utilization rate and is easy to operate, which can greatly reduce the workload.

[0067] In the embodiment of the present invention, the stabilization control device is loop-connected to the non-stop power transmission system introduced in the above embodiment based on the fixed value logic and branch matching relationship. Figure 2 The invention shows a schematic diagram of the circuit connection principle of a non-stop transmission suitable for a stabilizing control device.

[0068] like Figure 2 As shown, firstly, the stabilization action signal of the stabilization device 200 is connected to the signal input contact of the non-stop power transmission system 100; then, the load shedding outlets of each branch are connected to the load shedding contact of the non-stop power transmission system 100 in sequence; the closing wires of each branch of the non-stop power transmission system 100 are led out and connected to the closing input of the load interval operation box (i.e., the circuit breaker operation box). When the non-stop power transmission criterion (i.e., the output logic criterion introduced above) is met, the corresponding branch closing outlet is closed after a set delay.

[0069] In some embodiments, the stabilization control device 200 is connected to the non-stop power transmission system 100 in a loop based on the fixed value logic and the branch matching relationship, which can be specifically:

[0070] First, determine the validity of the load branch outlet of each branch. The value of the load branch outlet validity is 0 or 1. When the value of the load branch outlet validity is 0, it means that the load branch is a non-effective load branch or a load branch that does not need to be sheared, and the branch is skipped during the transmission test. When the value of the load branch outlet validity is 1, it means that the load branch is an effective load branch and needs to be connected to the loop, and the branch is included in the shearing object during the transmission test.

[0071] Then, effective load branches whose load branch outlet validity is 1 are selected from all branches.

[0072] Then, based on the preset load shedding monitoring input sequence number and closing output sequence number, the stabilization control device 200, the non-stop power transmission system 100 and each effective load branch are connected in a loop form. The load shedding monitoring input sequence number and the closing output sequence number are in one-to-one correspondence with the load branch sequence number.

[0073] Among them, the stabilizing action signal of the stabilizing control device 200 is connected to the signal input contact of the uninterruptible power transmission system 100; the load shedding outlets of each effective load branch are connected to the load shedding contact of the uninterruptible power transmission system 100 in sequence; the closing lines of each effective load branch led out from the uninterruptible power transmission system 100 are connected to the closing input contacts of the load interval operation box.

[0074] Based on the previous introduction of the non-stop power transmission system and the related circuit connection principle, refer to Figure 3 , shows a flowchart of a non-stop transmission method for a stabilization control device provided by an embodiment of the present invention, which may specifically include the following steps:

[0075] Step 301, when the branch load tripping outlet pressure plate of the stabilizing and controlling device is withdrawn, the stabilizing and controlling device performs a stabilizing and controlling device logic test based on a fixed value logic and generates an action message;

[0076] Before officially starting the test, the test personnel need to connect the output monitoring test line of the corresponding branch number of the non-stop power transmission system to the load shedding output circuit of the stabilization and control device according to the setting logic of the stabilization and control device and the branch matching relationship, and then connect the closing output test line of the corresponding branch number to the branch closing circuit, and finally connect the action signal monitoring test line to the action signal contact of the stabilization and control device.

[0077] Among them, setting logic refers to the specific parameters and logic conditions set for relay protection devices (stabilization devices), automatic control systems, etc., to ensure that these devices can correctly respond and perform corresponding actions under specific operating conditions. The setting logic and branch matching relationship in this step means that when the load branch outlet validity is 1, the test wiring is connected according to the load shedding monitoring opening number and closing outlet number of the non-stop power transmission system. For example, the loop connection example of the setting logic and branch matching relationship is shown in Table 1 below:

[0078]

[0079] Table 1: Example of circuit connection for fixed value logic and branch matching relationship

[0080] Among them, the load shedding monitoring input number refers to the input number inside the device connected to the monitoring test line of the corresponding branch number of the non-stop power transmission system. After the test line is connected, the load branch number corresponding to the load shedding output tripping action contact is closed, and the corresponding input number judgment contact is closed. The closing output number refers to the closing output contact number corresponding to the closing output test after the non-stop power transmission judgment criteria are met, and they all correspond to the load branch number one by one.

[0081] When the load tripping outlet pressure plate of the branch circuit of the stabilizing device is withdrawn, the test personnel can input the value of the electrical analog quantity (current and voltage analog quantity) that makes the stabilizing device operate according to the fixed value logic of the stabilizing device. Then the stabilizing device performs the logic test, generates the action message and sends it to the non-stop power transmission system. The non-stop power transmission system determines whether the action message is consistent with the fixed value logic of the logic test. If it is consistent, the next step of the test pressure plate input action is executed, otherwise the abnormal action of the stabilizing device is recorded and the test is ended.

[0082] Among them, the branch load tripping outlet pressure plate means that after the stabilizing device cuts off the load at the outlet, the electrical circuit must finally pass through the outlet pressure plate of the corresponding branch before the circuit breaker of the branch load can be opened.

[0083] From the perspective of control logic, the validity of the load branch outlet can also be understood as the branch element corresponding to any stabilization action logic control word is non-0. The stabilization action logic corresponding to the stabilization device can mainly include four action conditions: remote cut-off, overload, low frequency and low voltage, and line N-2. For example, for these four stabilization action conditions, Table 2 shows the set values ​​of a certain substation stabilization device, which is used to determine whether the load element participates in the load shedding logic of the stabilization device, and then corresponds according to the order of the load branch number.

[0084]

[0085] Table 2: Load element stabilization action logic control word input status

[0086] Taking load shedding action as an example, when the analog values ​​of current, voltage, power, etc. of the upper power supply element are too large (such as the values ​​of electrical quantities such as voltage, current or power exceed the preset maximum threshold or exceed the normal operating value range of the branch element) or when a remote load shedding instruction is received, the load is shelved according to the corresponding control word priority to maintain the stability of the power system. Among them, the control word priority means that when the logical control word is not 0, the branch load with a smaller logical control word value is preferentially shelved.

[0087] It can be understood that the priority of the logic control word refers to the priority sorting. For the four situations of remote cutting, overload, low frequency and low voltage, and line N-2, the corresponding priority sorting is unique and does not affect each other. After the logical conditions corresponding to a certain stabilization action logic are met, the load control action is performed according to the priority sorting. For example, remote cutting has a logic control word priority corresponding to remote cutting, and overload has a logic control word priority corresponding to overload, and the two are independent of each other and do not affect each other. Exemplarily, assuming that the stabilization control device determines that the power of the substation is greater than the overload value, it will be cut according to the logic control word priority sorting, such as preferentially cutting off the load element with a logic control word of 1. If the power returns to a normal value after cutting off the load element with a logic control word of 1, the cutting is stopped, otherwise the load element with a logic control word of 2 is continued, and so on. When multiple load elements have the same logic control word (such as multiple logic control words are all 1), they can be cut in order according to the load branch number, or they can be cut nearby, or load elements with a relatively concentrated range can be selected for cutting. The present invention does not limit the selection method for cutting load elements with the same logic control word.

[0088] In some embodiments, the process of performing a logic test of a stabilization device based on a fixed value logic includes the following sub-steps S01 to S03:

[0089] Step S01: obtaining the electrical analog value input by the user;

[0090] Step S02: judging the stabilization control action logic in combination with the electrical analog value, and obtaining the logic control word of each effective load branch in the loop under the stabilization control action logic;

[0091] Specifically, the following situations can be included in the judgment of the stabilization control action logic by combining the electrical analog value:

[0092] When the electrical analog value is greater than or equal to the preset maximum electrical threshold (such as exceeding the normal range of power operation), the stabilization action logic is judged to be overload.

[0093] When the electrical analog value is input and power imbalance occurs in the circuit, the stabilization control action logic is judged to be low frequency and low voltage.

[0094] After the electrical analog value is input, if any two effective load branches in the loop fail or are cut off at the same time, the stabilization control action logic is judged to be line N-2.

[0095] When the stabilizing control device receives a remote load shedding instruction, it determines that the stabilizing control action logic is remote shedding.

[0096] Step S03: Execute a load control action based on the priority of the logic control word on the effective load branch in the loop according to the stabilization control action logic.

[0097] Based on step S02, according to the stabilization action logic, a load control action based on the priority of the logic control word is performed on the effective load branch in the loop, which may include the following situations:

[0098] When the stabilization action logic is overload or remote cut-off, the effective load branch with the logic control word not 0 is cut off in order from small to large until the electrical quantity value in the circuit returns to the normal value range;

[0099] When the stabilization action logic is low frequency and low voltage, the frequency control or voltage control is performed on the effective load branch with the logic control word not being 0 in the order from small to large until the circuit restores the power balance;

[0100] When the stabilizing control action logic is line N-2, the automatic reclosing action is performed on the effective load branch that has failed or been cut off according to the logic control word value from small to large.

[0101] It should be pointed out that, thanks to the continuous improvement of power control technology, it is generally unlikely that multiple abnormal conditions will occur simultaneously in the operation of the power system. Unless a large-scale power outage occurs, causing the system to collapse. Generally speaking, the system collapse process occurs in the order of overload, low frequency and low voltage, line N-2, and remote cutting, and the action time of the corresponding devices is also different. Even if a situation may occur at the same time, each stabilization action logic is judged separately, and as long as the stabilization action logic is met, the load control action will be performed according to the priority. Among them, the priority of the logic control word is set by the fixed value setting personnel after analyzing the impact of the load according to different abnormal conditions.

[0102] Step 302, when the action message is consistent with the fixed value logic of the logic test of the stabilization control device, the non-stop power transmission system is put into the test pressure plate;

[0103] When the action message is consistent with the fixed value logic of the stabilization control device logic test, the tester will put the test plate of the non-stop power transmission system into operation. After the test is put into operation, it is determined whether the non-stop power transmission system test state is successfully put into operation. If it is successfully put into operation, the next non-stop power transmission test step will be executed, otherwise it will be recorded that the non-stop power transmission system test state is abnormal.

[0104] Step 303, when the test status of the non-stop power transmission system is successfully put into operation, the branch load tripping outlet pressure plate of the stabilization and control device is put into operation again to carry out the non-stop power transmission test.

[0105] The test personnel put into operation the branch load tripping outlet pressure plate of the stabilizing control device, and then input the current and voltage analog values ​​that activate the stabilizing control device.

[0106] Then the non-stop power transmission system cooperates with the non-stop power transmission to output the action report. Specifically, after the non-stop power transmission system confirms the stabilization control action, it determines whether the load shedding monitoring input judgment contact is closed. If it is closed, the corresponding closing outlet serial number contact is closed, and after the setting delay, the closing command is issued to close the corresponding branch load interval circuit breaker to achieve non-stop power transmission. If the judgment contact is not closed, the non-stop power transmission system records the load branch serial number of the incorrect outlet. The non-stop power transmission system integrates the branch action situation and outputs the final action report.

[0107] In the specific implementation, the branch load tripping outlet pressure plate of the stabilization control device is re-engaged to carry out the non-stop transmission test, which can be as follows: first, the branch load tripping outlet pressure plate of the stabilization control device is re-engaged; then the non-stop transmission system determines whether the non-stop transmission criterion is currently met. Combined with the previous content, it can be known that the non-stop transmission criterion means that the non-stop transmission system simultaneously meets the requirements of successful input of the test pressure plate, receiving the action contact closure signal of the stabilization control device and the load shedding outlet contact closure signal.

[0108] When the non-stop power transmission criterion is met, the non-stop power transmission system issues a closing command after a set delay to control the closing of the load bay circuit breaker of the effective load branch corresponding to the current load branch number.

[0109] When the non-stop power transmission criterion is not met, the non-stop power transmission system records the branch corresponding to the current load branch number as a valid load branch of an incorrect outlet.

[0110] Finally, the non-stop power transmission system integrates the action conditions of all branches of the non-stop power transmission test and generates a final action report.

[0111] In an embodiment of the present invention, a non-stop transmission system and method suitable for a conventional stabilization and control device are proposed. By means of external device access, the non-stop transmission system integrating multiple different functional modules is connected to the closing circuit of the load interval, and at the same time, the load shedding outlet circuit of the stabilization and control device is connected and monitored in real time. After confirming the load shedding outlet of the stabilization and control device, the system issues a closing outlet command corresponding to the load interval to realize the non-stop transmission of the stabilization and control device. This can not only effectively improve the efficiency of the transmission test of the stabilization and control device outlet, but also greatly improve the reliability of the power grid operation, and build a reliable stabilization and control anti-rejection system.

[0112] For better explanation, refer to Figure 4 , showing an overall flow diagram of a non-stop transmission method applicable to a stabilization control device provided by an embodiment of the present invention. It should be pointed out that this embodiment only briefly describes the general process of non-stop transmission applicable to a stabilization control device, and the specific implementation process of each step can be understood by referring to the relevant content in the aforementioned embodiment, which will not be described here. It can be understood that the present invention does not limit this.

[0113] Step 401, according to the fixed value logic and the branch matching relationship, the uninterruptible power transmission system, each effective load branch and the stabilization control device are connected in a loop; and step 402 is continued;

[0114] Step 402: When the load tripping outlet pressure plate of the branch circuit of the stabilizing and controlling device is withdrawn, the stabilizing and controlling device performs a logic test and generates an action message; and then proceeds to step 403;

[0115] Step 403, determine whether the action message is consistent with the fixed value logic of the logic test; if so, continue to execute step 404; if not, after recording the abnormal action of the stabilization control device, end the process;

[0116] Step 404, the non-stop transmission system is put into the test plate; continue to step 405;

[0117] Step 405, determining whether the non-stop power transmission system test state is successfully put into operation; if so, proceeding to step 406; if not, ending the process after recording the non-stop power transmission system test state put into operation abnormally;

[0118] Step 406, the stabilization control device puts the branch load tripping outlet pressure plate into operation to carry out a non-stop transmission test; determines whether the branch load shedding outlet is correct (i.e., whether the non-stop transmission criterion is met); if so, after recording that the branch load shedding outlet is correct and the switch outlet is closed, jumps to step 407; if not, after recording the incorrect outlet branch, jumps to step 407;

[0119] Step 407: The non-stop power transmission system integrates the operation conditions of all branches of the non-stop power transmission test, generates an operation report, and outputs it to the user interface for the test personnel to view, thereby ending the process.
