Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of power distribution network, and in particular to an online self-healing test system. Background Art

[0002] The distribution network self-healing function is the core function of the distribution network. The correctness of its action logic is the key to ensuring the rapid isolation of faults and rapid restoration of power supply in the distribution network. Therefore, any investment in a new distribution network self-healing function requires a rigorous, comprehensive and effective testing and verification process.

[0003] At present, on-site tests of the self-healing function of the distribution network mostly adopt on-site modes, such as terminal injection method, mixed injection method or case preset method, etc. The core is to calculate the electrical quantity of each site through the flow, and then control the synchronous output of the tester status sequence through networking or timing. At the same time, the main station operation and maintenance personnel manually check and judge whether the distribution network self-healing strategy is correct on the main station side.

[0004] However, during the on-site testing process, since most distribution terminals are wireless communications and the communication quality is sometimes good and sometimes bad, it is often the case that the terminal side operates correctly, but the distribution network self-healing strategy is wrong on the master station side, which needs to be solved urgently.

[0050] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme 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 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 should fall within the scope of protection of the present invention.

[0051] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. The situations of "target", "original", etc. are similar and will not be repeated here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0052] In order to better understand the online self-healing test system described in the following embodiments, Figure 1a and Figure 1b The various parts and workflow of the online self-healing test system are briefly described by way of example.

[0053] Exemplarily, the online self-healing test system may include five parts: an operation and maintenance main station, a self-healing tester, a power distribution terminal, a data forwarding service, and an operation control system (OCS). The specific functions of each part are as follows:

[0054] Operation and maintenance master station: deployed in the safety zone III of the distribution network dispatching master station, it is mainly used to generate topology files, generate self-healing test cases, receive terminal signals uploaded by self-healing testers and distribution terminals, and generate self-healing test reports.

[0055] Self-healing tester: mainly used to generate topology information, receive self-healing test cases from the operation and maintenance master station, execute self-healing test cases, and receive the first terminal signal of the distribution terminal.

[0056] Distribution Terminal: The terminal to be tested.

[0057] Data forwarding service: Send the self-healing test case to the self-healing tester, and upload the first terminal signal collected by the self-healing tester to the OCS.

[0058] OCS: Collects the second terminal signal of the power distribution terminal and the first terminal signal of the self-healing tester, and transmits these terminal signals to the operation and maintenance main station located in the safety zone III through the forward and reverse isolation equipment.

[0059] On this basis, the specific working process of the above online self-healing test system is as follows:

[0060] The operation and maintenance master station deployed in the safety zone III finds out the lines under test whose self-healing strategy fails to operate correctly at the time of the fault based on the historical data of each distribution line, and generates a debugging list, which includes the switch name of the line under test and the Internet Protocol (IP) address of each station under test on the line under test.

[0061] The on-site operation and maintenance personnel view the debugging order on the Web terminal, go to the line to be tested, and deploy the self-healing tester at each site to be tested, where the power distribution terminal is located at the site to be tested. After the operation and maintenance personnel establish a link between the self-healing tester and the operation and maintenance master station, they click Get Debug Order and select the current node name of the current node, the previous node name of the previous node of the current node, the next node name of the next node of the current node, and the switch type corresponding to the current node, previous node, and next node. After the configuration is completed, the on-site operation and maintenance personnel click Upload Topology, and the self-healing tester uploads the topology information to the operation and maintenance master station.

[0062] Then, the operation and maintenance master station analyzes the topology information of each site to be tested and draws a topology file based on the analysis results. After the topology file is successfully drawn, the master station operation and maintenance personnel set up self-healing test cases based on the topology file and click Generate Self-Healing Test Cases. At this time, the operation and maintenance master station can automatically generate self-healing test cases executed by self-healing testers deployed at different sites to be tested and action strategies for each state sequence.

[0063] Furthermore, after the operation and maintenance master sends the self-healing test case to the self-healing tester, the operation and maintenance master starts the test. The self-healing tester collects the first terminal signal of the distribution terminal and sends it to the operation and maintenance master. The operation and maintenance master simultaneously obtains the second terminal signal sent by the distribution terminal to the OCS, and performs an "AND" operation on the two, compares them with the preset distribution network self-healing strategy, obtains the self-healing test report, and archives it electronically.

[0064] Next, the above-mentioned online self-healing test system will be described in detail in combination with the following embodiments.

[0065] Figure 2 This is a structural block diagram of an online self-healing test system provided by an embodiment of the present invention. This embodiment is applicable to the online test of the self-healing strategy of the distribution network.

[0066] See also Figure 2 , the online self-healing test system according to the embodiment of the present invention comprises: an operation and maintenance master station 10, a power distribution terminal 11, and a self-healing tester 12 deployed for testing the power distribution terminal 11;

[0067] The operation and maintenance master station 10 is used to generate a self-healing test case for the power distribution terminal 11 and send the self-healing test case to the self-healing tester 12;

[0068] The self-healing tester 12 is used to execute the received self-healing test case on the power distribution terminal 11, and upload the collected first terminal signal of the power distribution terminal 11 to the operation and maintenance main station 10;

[0069] The power distribution terminal 11 is used to upload the acquired second terminal signal to the operation and maintenance main station 10;

[0070] The operation and maintenance master station 10 is further used to compare the received first terminal signal and the second terminal signal, and compare them with the preset distribution network self-healing strategy to test the distribution network self-healing strategy.

[0071] The power distribution terminal 11 can be understood as a terminal to be tested. In the embodiment of the present invention, the power distribution terminal 11 can optionally be called a feeder terminal or a feeder automation terminal, etc., which is not specifically limited here.

[0072] The self-healing tester 12 can be deployed after the power distribution terminal 11 on the line to be tested is determined, and has a plug-and-play relationship with the operation and maintenance master station 10 .

[0073] The self-healing test case can be understood as a case for testing the self-healing strategy of the distribution network. In the embodiment of the present invention, optionally, the self-healing test case can also be called a feeder automation (FA) test case, etc., which is not specifically limited here.

[0074] The first terminal signal can be understood as the signal of the power distribution terminal 11 collected by the self-healing tester 12 during the test, and in particular, can be understood as the collected signal of the action outlet of the power distribution terminal 11. The second terminal signal can be understood as the signal obtained by the power distribution terminal 11 collecting its own signal during the test. In the embodiment of the present invention, optionally, both the first terminal signal and the second terminal signal can be real-time signals.

[0075] Different from the conventional on-site mode test of the distribution network self-healing strategy, the online self-healing test system proposed in the embodiment of the present invention tests the distribution network self-healing strategy through the online mode, which combines the real-time second terminal signal of the distribution terminal 11 with the first terminal signal collected locally in real time by the self-healing tester 12. On the one hand, the action signal (i.e., the first terminal signal) of the distribution terminal 11 is collected in real time by the self-healing tester 12 during the addition process, and on the other hand, the second terminal signal sent by the distribution terminal 11 is monitored in real time at the operation and maintenance master station 10 of the distribution automation dispatching, and then the two sets of signals are combined to verify the consistency of the signals, so as to avoid the distribution terminal 11 from signal loss due to communication quality and other problems, the operation and maintenance master station 10 locating the fault, and the distribution network self-healing strategy and the actual action of the on-site monitoring distribution terminal 11 are inconsistent, resulting in misjudgment. Moreover, after taking the "AND" of the first terminal signal collected by the self-healing tester 12 and the second terminal signal monitored in real time by the operation and maintenance master station 10, it is compared with the distribution network self-healing strategy preset by the operation and maintenance master station 10, without manually judging whether the distribution network self-healing strategy is correct or not, that is, without manual intervention, so that the given self-healing test result is more in line with the actual situation.

[0076] The online self-healing test system described in the embodiment of the present invention may include: an operation and maintenance main station, a distribution terminal, and a self-healing tester deployed for testing the distribution terminal; wherein, through the operation and maintenance main station, a self-healing test case is generated for the distribution terminal, and the self-healing test case is sent to the self-healing tester; through the self-healing tester, the received self-healing test case is executed for the distribution terminal, and the first terminal signal of the distribution terminal collected is uploaded to the operation and maintenance main station; through the distribution terminal, the second terminal signal collected by itself is uploaded to the operation and maintenance main station; through the operation and maintenance main station, the received first terminal signal and the second terminal signal are compared, and compared with the preset distribution network self-healing strategy to test the distribution network self-healing strategy. The technical solution of the embodiment of the present invention, by adopting an online test mode, synchronously verifies the distribution network self-healing strategy on the main station side and the local side, realizes the online test of the distribution network self-healing strategy, and meets the demand for distribution network self-healing test.

[0077] In an optional technical solution, the operation and maintenance master station is further used to store the current test result of the distribution network self-healing strategy based on a preset storage strategy, wherein the preset storage strategy includes at least one of the following:

[0078] Store the test results of the current time;

[0079] Based on the overwriting method or the appending method, the test result of the current time is stored; and,

[0080] Based on the current test results, the previous test results of the distribution network self-healing strategy are covered.

[0081] In the present technical scheme, according to the analysis of actual needs, the storage of the current test results can be mainly divided into three situations: the first situation is to directly store the current test results, that is, each test result is stored and can be marked by "sample unique identification + test time"; the second situation is to store each test result, but when storing the current test result, you can choose to overwrite the previous test result or append the current test result according to the test situation. If it is the former, the previous test result can be updated through "sample unique identification + latest test time". If it is the latter, the previous test result can be retained while the current test result is stored through "sample unique identification + latest test time"; the third situation is to automatically overwrite the previous test result, that is, only the latest test result is always retained.

[0082] On this basis, optionally, after the test is completed, the operation and maintenance main station can generate an electronic self-healing test report based on the test results of that time. The self-healing test report can include information such as the expected action strategy, the actual action strategy, and test screenshots, and truly record the test process.

[0083] The above technical solution can select a suitable preset storage strategy to store the test results according to actual needs, which is helpful for the subsequent further application of the test results.

[0090] The dispatching and control system 22 is further used to forward the received first terminal signal and the second terminal signal to the operation and maintenance main station 20;

[0091] The operation and maintenance master station 20 is further used to compare the received first terminal signal and the second terminal signal, and compare them with the preset distribution network self-healing strategy to test the distribution network self-healing strategy.

[0092] The technical solution of the embodiment of the present invention realizes the effective flow of self-healing test cases and terminal signals between the operation and maintenance main station and the power distribution terminal and the self-healing tester by setting up a dispatching control system.

[0096] The above technical solution realizes the safe and effective flow of data through data forwarding service.

[0097] Figure 4It is a structural block diagram of another online self-healing test system provided by an embodiment of the present invention. This embodiment is optimized based on the above-mentioned technical solutions. In this embodiment, optionally, the self-healing tester is also used to send a registration message to the operation and maintenance main station to establish a link with the operation and maintenance main station through the registration message; the operation and maintenance main station is also used to send the switch name of the switch to be tested corresponding to the distribution terminal to the self-healing tester when the link is successfully established; the self-healing tester is also used to obtain the site information selected for the received switch name, and send the site information to the operation and maintenance main station; the operation and maintenance main station is also used to bind the self-healing tester to the switch site represented by the site information according to the received site information. Among them, the explanations of the terms that are the same or corresponding to the above-mentioned embodiments are not repeated here.

[0098] For details, see Figure 4 , the online self-healing test system described in this embodiment includes: an operation and maintenance master station 30, a power distribution terminal 31, and a self-healing tester 32 deployed for testing the power distribution terminal 31;

[0099] The self-healing tester 32 is used to send a registration message to the operation and maintenance main station 30 to establish a link with the operation and maintenance main station 30 through the registration message;

[0100] The operation and maintenance master station 30 is used to send the switch name of the switch to be tested corresponding to the power distribution terminal 31 to the self-healing tester 32 when the link is successfully established;

[0101] The self-healing tester 32 is also used to obtain the site information selected for the received switch name and send the site information to the operation and maintenance main station 30;

[0102] The operation and maintenance master station 30 is further used to bind the self-healing tester 32 to the switch site represented by the site information according to the received site information;

[0103] The operation and maintenance master station 30 is also used to generate a self-healing test case for the power distribution terminal 31 and send the self-healing test case to the self-healing tester 32;

[0104] The self-healing tester 32 is further used to execute the received self-healing test case for the power distribution terminal 31, and upload the collected first terminal signal of the power distribution terminal 31 to the operation and maintenance main station 30;

[0105] The power distribution terminal 31 is used to upload the acquired second terminal signal to the operation and maintenance main station 30;

[0106] The operation and maintenance master station 30 is further used to compare the received first terminal signal and the second terminal signal, and compare them with the preset distribution network self-healing strategy to test the distribution network self-healing strategy.

[0107] The technical solution of the embodiment of the present invention helps to carry out the subsequent testing process of the distribution network self-healing strategy by binding the self-healing tester with the operation and maintenance master station.

[0108] In an optional technical solution, the registration message includes an Internet Protocol address and an access password;

[0109] The operation and maintenance main station is also used to establish a link with the self-healing tester when the received Internet protocol address and access password are correct;

[0110] The operation and maintenance main station is also used to establish an access channel according to the Internet Protocol address when the received Internet Protocol address does not exist and the received access password is correct, so as to establish a link with the self-healing tester through the access channel.

[0111] The above technical solution can establish a link between the self-healing tester and the operation and maintenance main station under different circumstances.

[0112] On this basis, in order to better understand the various technical solutions described in the embodiments of the present invention, Figure 1a The examples given are illustrative. For example, see Figure 1a The specific implementation process is as follows:

[0113] The self-healing tester and the secure access zone need to communicate encrypted. In order to ensure normal communication between the self-healing tester and the secure access zone, the operation and maintenance personnel need to configure the built-in encryption communication module of the self-healing tester and authenticate the encryption certificate to ensure that the transmission control protocol (TCP) link between the self-healing tester and the secure access zone is normal.

[0114] After the initial configuration, the TCP link between the data forwarding service located in the front area of ​​the operation and maintenance master station and the OCS located in the security zone I is activated. The OCS can communicate normally with the operation and maintenance master station located in zone III.

[0115] After the self-healing tester is turned on, the TCP link with the operation and maintenance master station is connected, but the operation and maintenance master station does not know the site information of the switch site corresponding to each self-healing tester, resulting in the inability to bind the self-healing tester to the corresponding switch site. Therefore, when the self-healing tester is online, it can actively send a registration message to the operation and maintenance master station, and the registration message can contain the IP address and access password. If the IP address and access password are correct, a link between the operation and maintenance master station and the self-healing tester is established; if the IP address does not exist locally but the access password is correct, the master station operation and maintenance personnel need to establish an access channel for the IP address and establish a link. After the link is successfully established, the operation and maintenance master station can send the switch name of the switch to be tested to the self-healing tester, and the on-site operation and maintenance personnel manually select the site information corresponding to the self-healing tester and click Register, thereby sending the site name corresponding to the self-healing tester, the ID number of the self-healing tester, and the phone card IP of the self-healing tester to the operation and maintenance master station, and the operation and maintenance master station binds the self-healing tester to its corresponding switch site.

[0116] The above example uses plug-and-play technology to achieve plug-and-play between the self-healing tester and the operation and maintenance main station, without the need for cumbersome communication configuration, and is highly convenient.

[0117] Figure 5 It is a structural block diagram of another online self-healing test system provided by an embodiment of the present invention. This embodiment is optimized based on the above-mentioned technical solutions. In this embodiment, optionally, the self-healing tester is also used to generate topology information associated with the distribution terminal, and upload the topology information to the operation and maintenance main station; the operation and maintenance main station is specifically used to draw a topology file based on the received topology information, so as to generate a self-healing test case for the distribution terminal according to the topology file, and send the self-healing test case to the self-healing tester. Among them, the explanations of the terms that are the same or corresponding to the above-mentioned embodiments are not repeated here.

[0118] For details, see Figure 5 , the online self-healing test system described in this embodiment includes: an operation and maintenance master station 40, a power distribution terminal 41, and a self-healing tester 42 deployed for testing the power distribution terminal 41;

[0119] The self-healing tester 42 is used to generate topology information associated with the power distribution terminal 41 and upload the topology information to the operation and maintenance main station 40;

[0120] The operation and maintenance master station 40 is used to draw a topology file according to the received topology information, so as to generate a self-healing test case for the power distribution terminal 41 according to the topology file, and send the self-healing test case to the self-healing tester 42;

[0121] The self-healing tester 42 is further used to execute the received self-healing test case for the power distribution terminal 41, and upload the collected first terminal signal of the power distribution terminal 41 to the operation and maintenance main station 40;

[0122] The power distribution terminal 41 is used to upload the acquired second terminal signal to the operation and maintenance main station 40;

[0123] The operation and maintenance master station 40 is further used to compare the received first terminal signal and the second terminal signal, and compare them with the preset distribution network self-healing strategy to test the distribution network self-healing strategy.

[0124] The technical solution of the embodiment of the present invention adopts the automatic topology generation technology. After the self-healing tester sends the topology information to the operation and maintenance main station, the operation and maintenance main station can automatically draw the topology file according to the topology information of each site to be tested. That is, there is no need to manually draw the topology file, which effectively reduces the labor cost.

[0125] An optional technical solution, a self-healing tester, is also specifically used to respond to a topology information generation instruction associated with a distribution terminal, obtain generation information, generate topology information based on the generation information, and upload the topology information to an operation and maintenance main station, wherein the generation information includes the current node name of the current node, the previous node name of the previous node of the current node, the next node name of the next node of the current node, and the switch types corresponding to the current node, the previous node, and the next node.

[0126] The above technical solution realizes the effective generation of topology information through the node name of each node and the corresponding switch type.

[0127] On this basis, in order to better understand the various technical solutions described in the embodiments of the present invention, Figure 6a and Figure 6b The example given is used for illustrative purposes. For example, the specific implementation process is as follows:

[0128] After the on-site operation and maintenance personnel establish a link between the self-healing tester and the operation and maintenance main station, they click to obtain the debugging order. After obtaining the debugging order, the on-site operation and maintenance personnel can obtain the names of all nodes on the line to be tested.

[0129] See also Figure 6a and Figure 6b , here taking KG1 as an example, the on-site operation and maintenance personnel select the current node name as KG1, the previous node name as CK1, the next node name as KG2, and the switch type as segmented switch.

[0130] Here, taking the branch switch KG7 as an example, the on-site operation and maintenance personnel select the current node name as KG7, the previous node name as KG2, the next node name as KG3, and the switch type as a branch switch.

[0131] The configuration of the remaining nodes is the same as the above, and will not be described in detail here. In this example, the node name may also be called the site name, which can be set according to actual needs and is not specifically limited here.

[0132] After filling in the information, click Upload Topology Information, and the self-healing tester can upload the topology information to the operation and maintenance master station. Then, the operation and maintenance master station can analyze the topology information of each site to be tested and draw a topology file (i.e., test topology map).

[0133] In the above example, the automatic topology generation technology is used. The self-healing tester can generate topology information based on its own point information and send the topology information to the operation and maintenance main station. The operation and maintenance main station can then automatically generate a test topology map based on the topology information of each site to be tested without manual drawing, thereby effectively reducing labor costs.

[0134] Figure 7 It is a structural block diagram of another online self-healing test system provided by an embodiment of the present invention. This embodiment is optimized based on the above-mentioned technical solutions. In this embodiment, optionally, the operation and maintenance main station is specifically used to obtain the lines to be tested with self-healing strategy action errors at the time of the fault from each distribution line according to the historical data of each distribution line; the operation and maintenance main station is specifically used to generate self-healing test cases for the distribution terminals on the lines to be tested according to the type of self-healing strategy action errors, and send the self-healing test cases to the self-healing tester. Among them, the explanations of the terms that are the same or corresponding to the above-mentioned embodiments are not repeated here.

[0135] For details, see Figure 7 , the online self-healing test system described in this embodiment includes: an operation and maintenance master station 50, a power distribution terminal 51, and a self-healing tester 52 deployed for testing the power distribution terminal 51;

[0136] The operation and maintenance main station 50 is used to obtain the lines to be tested whose self-healing strategy has an error at the time of the fault from each distribution line according to the historical data of each distribution line;

[0137] The operation and maintenance master station 50 is also used to generate a self-healing test case for the distribution terminal 51 deployed on the line to be tested according to the type of self-healing strategy action error, and send the self-healing test case to the self-healing tester 52

[0138] The self-healing tester 52 is used to execute the received self-healing test case on the power distribution terminal 51, and upload the collected first terminal signal of the power distribution terminal 51 to the operation and maintenance main station 50;

[0139] The power distribution terminal 51 is used to upload the collected second terminal signal to the operation and maintenance main station 50;

[0140] The operation and maintenance master station 50 is further used to compare the received first terminal signal and the second terminal signal, and compare them with the preset distribution network self-healing strategy to test the distribution network self-healing strategy.

[0141] The technical solution of the embodiment of the present invention generates a self-healing test case for the power distribution terminal on the line to be tested according to the type of self-healing strategy action error, thereby improving the accuracy of self-healing test case generation.

[0142] An optional technical solution, the operation and maintenance master station, is specifically used to determine the indicator to be tested according to the type of the self-healing strategy action error, and determine a matching test case that matches the indicator to be tested from each candidate test case;

[0143] The operation and maintenance master station is specifically used to send the matching test case as a self-healing test case generated for the power distribution terminal deployed on the line to be tested to the self-healing tester.

[0144] The above technical solution generates a self-healing test case by matching each candidate test case, thereby further improving the accuracy of the self-healing test case generation.

[0145] On this basis, in order to better understand the various technical solutions described in the embodiments of the present invention, the following is an exemplary description in conjunction with specific examples. For example, the specific implementation process is as follows:

[0146] The operation and maintenance master station deployed in the safety zone III finds the lines to be tested with self-healing strategy errors at the time of the fault based on the historical data of each distribution line, and matches the self-healing test cases according to the type of self-healing strategy action error on the lines to be tested. In order to simplify the workload of the master station operation and maintenance personnel, the self-healing test cases are automatically generated using technology. The self-healing test cases are divided into several states, such as the initial state, fault state, and final state, and different states can be used as candidate test cases. When generating self-healing test cases, each candidate test case is automatically traversed according to the indicator to be tested, and the candidate test cases related to the indicator to be tested are extracted to form a self-healing test case. When there is no corresponding candidate test case for the indicator to be tested, the relevant personnel can be automatically reminded to intervene in the operation.

[0147] In addition, typical self-healing strategies can be generated based on the expert database and compared with the actual distribution network self-healing strategies on site.

[0148]

[0149] Refer to the table above. Taking overcurrent fault as an example, the overcurrent fault is divided into three states: initial state 1, fault state 2 and final state 3. Among them, the initial state and final state are unchanged; the three-phase current and duration of the fault state are pre-bound with the threshold and time of the overcurrent fault, respectively, and set to 1.2 times the threshold to generate a state sequence. When overcurrent occurs, the switches upstream of the fault point are all in the overcurrent state, and the switches downstream of the fault point are not faulty.

[0150] The above example realizes the automatic generation of self-healing test cases.

[0151] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
