Description

Technical Field

[0001] The present invention relates to the field of power system automation, and particularly to a one-key sequence control automatic verification method based on a substation SCD model file. Background Art

[0002] The one-key sequence control test system for intelligent substations is a test system aiming to verify the feasibility and correctness of the one-key sequence control system for intelligent substations, and is an important inspection part in the popularization and use of the one-key sequence control system for intelligent substations.

[0003] First, the current one-key sequence control verification method relies heavily on manual operations in data configuration and actual verification, with many manual errors during configuration. Moreover, in the existing power-off one-key sequence control verification method, a large amount of time is often required for debugging during the test with the actual on-site sequence control host. Secondly, there is a large amount of data in the SCD model file, and many data information is not related to one-key sequence control, resulting in data redundancy and long search time for configuration work.

[0004] The invention patent with the publication number CN110989547A mentions a detection method and system for a one-key sequence control system of an intelligent substation. It uses the device state migration method to perform device state migration on the device under test, realizes the logical decoupling of the device state and the current test device, and uses the SCD model for data distribution to achieve the unity of test data and communication methods. The simulated sequence control host among them is a one-key sequence control test device, which plays different roles based on different states of the device under test. When in use, it still needs to be connected to the actual device under test and has actual requirements for the on-site test environment. Summary of the Invention

[0021] S2-2 combines the content of the one-key sequential control background operation ticket to determine other characteristic quantities involved in the above nodes, and configures the logical relationship between the node information to obtain the node composition of the switch topology diagram; other characteristic quantities are such as analog quantity, pressure plate status, five-protection logic signal, etc.

[0022] S2-3 combines the main wiring diagram of the primary equipment to establish a switch topology diagram of all intervals in the entire substation. The switch topology diagram has a communication function. After receiving the switch change signal, when the remote control point value and / or graph changes, the other characteristic quantities change according to the preconfigured logic.

[0023] Further, including:

[0024] The step S2-1 comprises the following steps:

[0025] S2-1-1 Based on the Chinese name in the primary equipment information table, match the measurement and control equipment information obtained by parsing in the SCD model file to confirm the correspondence between the interval and the measurement and control equipment;

[0026] S2-1-2 uses the measurement and control equipment number as the keyword to filter through the relevant IED attribute information, and combines the Chinese name in the primary equipment information table to obtain the switch device name, switch device type, interval analog quantity and remote control point information.

[0027] The remote control point information described in S2-1-3 should correspond to the switch device one by one, and the logic of the corresponding relationship change between the analog quantity and the remote control point information should be pre-configured.

[0028] Further, including:

[0029] In the step S3, the real-time status of each switch device model is displayed on the switch topology diagram according to the corresponding interval for change verification, including:

[0030] S31: If the switch device model receives the remote control command and the switch position is changed, the remote control point information and analog quantity information in the switch device model are first verified, and the result is fed back after the verification is completed;

[0031] S32: the switch topology receives the verification result and changes according to the current state of the switch position;

[0032] S33 performs switch position change verification one by one for all switch device models that have been configured, and records the result and action completion time of each switch position change until all switch device models have completed the change verification.

[0033] Further, including:

[0034] In step S4, generating a verification operation ticket according to the key information of the operation ticket configuration specifically includes:

[0035] S41 Obtain the corresponding substation bay attribute information according to the switch topology diagram, including: bay name, bay type, name of the measurement and control device, and voltage level;

[0036] S42 Obtain the configuration key information of the operation ticket from the Chinese name of the one-key sequence control background operation ticket, including: operation ticket name, operation ticket bay, operation ticket execution sequence, equipment involved in the operation ticket, and operation ticket steps;

The information of the verified operation ticket shall be no less than the name of the measurement and control device, starting switch position, switch position in the steps, analog quantity information, name of the bay to which it belongs, and switch device type.

[0038] Furthermore, it includes:

[0039] Step S5 specifically includes pre-verification, and the pre-verification includes:

[0040] S51 The built-in simulated sequence control host reuses and constructs the switch device characteristic quantities and data extracted during the construction of the switch topology diagram, and stores them in the database of the simulated sequence control host. The switch device characteristic quantities and data include: substation bay name, bay type, name of the measurement and control device, switch device name, switch device type, bay analog quantity, remote control point information, other characteristic quantities, and change logic;

[0041] S52 The simulated sequence control host is directly connected to the actual sequence control host, and the sequence control host issues a sequence control command. At the start of the one-key sequence control command, the simulated sequence control host resets the initial position of the switch according to the requirements of the verified operation ticket;

[0042] S53 After the command is issued, the simulated sequence control host receives the command, conducts a remote control point comparison, returns a remote control result based on the comparison result, and modifies the switch position status;

[0043] S54 The simulated sequence control host receives the remote control result, modifies the remote control point value in the database of the simulated sequence control host, and changes the other characteristic quantities according to the preset logic. The corresponding switch topology diagram is also modified and changed according to the remote control result;

[0044] S55 The simulated sequence control host judges the result of the one-key sequence control step according to the returned remote control result and analog quantity change, and then proceeds to the next step or aborts with an error message.

[0050] In the subsequent verification steps, the switch device model is real-time associated with the switch topology diagram, and the switch topology diagram reflects the current state of the switch model in real time;

[0051] S5-3 Gradually verify according to the steps of the verification operation ticket. The simulated sequence control host issues a sequence control command, and matches the remote control point information involved in the sequence control command with the remote control point information in the verification operation ticket. If the match is successful, the switch position in the switch device model changes and the switch topology diagram changes; the criterion for successful match is the same Chinese name of the switch device, the measuring and control equipment number, and the configured remote control point information value;

[0052] After completing a single step, verify the interval analog quantity. If it is within the normal range, proceed to the verification of the initial position of the next step.

[0055] (2) The present invention has a built-in simulated sequence control host, which can perform self-correctness verification before actual verification to reduce on-site debugging time. Moreover, the verification of the present invention includes forward verification and reverse verification, verifying that the test system itself can correctly feedback when the sequence control command configuration conforms to the remote control points of the on-site SCD model file, and can correctly report an error when it does not conform to the remote control points of the SCD model file, thereby ensuring the correctness of the test system itself and the reliability of the communication function.

[0065] To better understand the present invention, the technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0066] As Figure 1 shown, the one-key sequence control automatic verification method based on the substation SCD model file described in the present invention includes the following steps:

[0067] S1 Combine the primary equipment main wiring diagram, list the primary equipment information table, and determine the IED attributes in the SCD model file. Parse the SCD model file to obtain the configuration description information in the SCD model file. The configuration description information retains the data required for one-key sequence control verification according to the IED attributes, including at least: key attributes such as switch device type, switch device name, and bay name.

[0068] Among them, the primary equipment information table contains all switch devices involved in one-key sequence control. The SCD file in the IEC61850 standard system follows the specification of "IEC61850-6 Substation Communication Configuration Description Language SCL" and is an important data relied on for the operation, daily maintenance, and engineering management of substation equipment. The SCD model file generated according to the IEC61850 specification is used to describe the information of the primary and secondary equipment of the entire substation.

[0069] S2 analyzes the configuration description information, extracts the switchgear attribute information, and constructs the switch topology diagram of all bays in the entire substation.

[0070] Among them, in this embodiment, the configuration information is analyzed, and the switchgear attribute information is extracted, such as Figure 2 shown, including:

[0071] S21 determines the IED attributes according to the naming rules of the current switchgear through keywords and / or data characteristics. The IED attributes include: switchgear type, bay number, voltage level, remote control point information, and analog quantity information, and then completes the IED attribute setting corresponding to all switchgears.

[0072] S22 screens and filters according to the attribute classification of the IED attributes, eliminates redundant data, completes the IED creation, and then obtains the switchgear attribute information, including: switchgear name, switchgear type, affiliated bay name, remote control point information, and analog quantity information.

[0073] Then all the data is stored according to the attribute classification as the subsequent data source, and the remaining redundant data is filtered and not retained in the database later.

[0074] Furthermore, in this embodiment, in step S22, eliminating the redundant data includes eliminating the bay number and manufacturer identification, and when performing relevant parameter configuration, only the communication parameters involved in one-key sequence control are extracted according to the IED attributes, and the relevant parameters of the redundant data are not obtained anymore.

[0075] In the early stage of the present invention, reasonable attribute definitions are made for the SCD model file. When extracting configuration information, targeted configuration information acquisition and classification storage are carried out for the attributes. After filtering unnecessary data, the automation of data configuration work can be significantly improved, thereby realizing the automatic verification of one-key sequence control.

[0076] By adopting the method of classifying the attributes of the SCD file in advance and screening effective information, the useless data information is reduced, and the utilization efficiency of the database data is improved.

[0077] The prior art often models and uses the SCD model file as a whole. The information is comprehensive but the data volume is large, and a lot of information is not used in the one-key sequence control verification summary. In the subsequent data configuration work, whether it is manual or automated configuration, useless redundant data will increase the workload.

[0078] The present invention adopts pre-attribute classification, filters invalid information in advance based on past work experience, and only retains the switchgear information, bay information, etc. involved in the one-key sequence control process, thereby greatly reducing the subsequent data volume, reducing the workload for subsequent automated configuration and manual correction, and improving the efficiency.

[0079] In step S2, in this embodiment, in combination with the interval characteristics of the substation primary wiring diagram and the main wiring diagram, according to the switch topology information and switch device attributes obtained by parsing, a topology node is constructed, the node information is improved, and a substation switch topology diagram is constructed, such as Figure 3 As shown, including:

[0080] S2-1 determines the measurement and control equipment corresponding to the substation interval where the current switch device is located according to the primary equipment information table, uses the measurement and control equipment number as the keyword, matches it with the interval number in the IED attribute, and obtains the corresponding switch device attribute information node, including: switch device name, switch device type, interval analog quantity, and remote control point information.

[0081] The conventional method is to use the configuration tool to parse the SCD file through the program, extract information from key frames and keywords according to the naming rules, create IED, and configure related parameters.

[0082] In the present invention, when extracting information, the naming rules are followed, and the IED attributes are determined by keywords or data characteristics. According to the IED attributes, the information is screened and classified, and redundant data such as interval numbers and manufacturer identifications are removed in advance to complete the IED creation. When configuring related parameters, only the communication parameters involved in the one-key sequential control are extracted according to the IED attributes, and the related parameters of the redundant data are no longer obtained.

[0083] S2-2 combines the content of the one-key sequential control background operation ticket to determine other characteristic quantities involved in the above nodes, and configures the logical relationship between the node information to obtain the node composition of the switch topology diagram.

[0084] Since the IED information has been filtered at this time, combined with the Chinese device name in the device information table, the corresponding switch device name, switch device type, interval analog quantity, remote control point information and other nodes can be quickly read and matched to form important information.

[0085] Then, based on the interval characteristics and the contents of the sequential control operation ticket, determine other characteristic quantities involved in the node, such as analog quantity, pressure plate status, five-protection logic signals, etc., and configure the logical relationship between the node information. For example, the analog quantity change logic when the remote control point changes, the pressure plate status conditions when the remote control point changes, etc. It should be noted that this analog quantity change logic configuration is configured for some manufacturers' sequential control hosts to use analog quantity changes as one of the sequential control verification conditions. In actual testing, it does not represent the real-time analog quantity value of the actual on-site power system. Other characteristic values ​​such as pressure plate status, five-protection logic, etc. can also follow this mode.

[0086] S2-3 completes the above node composition, and combines the main wiring diagram of the primary equipment to establish the switch topology diagram of all intervals in the entire substation. The switch topology diagram has a communication function. After receiving the switch position change signal, when the remote control point value and / or graph changes, the other characteristic quantities change according to the pre-configured logic.

[0087] Further, such as Figure 4 As shown, in this embodiment, step S2-1 includes the following steps:

[0088] S2-1-1 matches the measurement and control equipment information obtained by parsing in the SCD model file based on the Chinese name in the primary equipment information table to confirm the correspondence between the interval and the measurement and control equipment.

[0089] S2-1-2 uses the measurement and control equipment number as the keyword to filter through the relevant IED attribute information, and combines the Chinese name in the primary equipment information table to obtain the switch device name, switch device type, interval analog quantity and remote control point information.

[0090] The remote control point information and switchgear described in S2-1-3 should correspond one to one. The corresponding relationship change logic between analog quantity and remote control point information can be pre-configured. This analog quantity change logic configuration is configured for some manufacturers' sequential control hosts to use analog quantity changes as one of the sequential control verification conditions. It does not represent the real-time analog quantity value of the actual on-site power system during actual testing. Other characteristic values ​​such as pressure plate status, five-protection logic, etc. can also follow this mode.

[0091] S3 constructs a switch device model based on the switch device attribute information. The switch device model itself has a communication module, which remotely controls the received command, identifies the analog information and feeds back the comparison result between the remote control point and the analog information; and displays the real-time status of each switch device model on the switch topology diagram according to the corresponding interval for change verification.

[0092] In this embodiment, the switch device model includes the switch device name, switch device type, remote control action point information value in the SCD file, interval name, and analog quantity in the interval. Since the data has been filtered before, this step can be completed automatically by the program. The switch device model itself has a communication module, which can perform standard 61850 communication, and can perform remote control point and analog quantity information recognition on the received command and feedback the comparison result of the remote control point and analog quantity information.

[0093] For the completed switchgear model, automatically match it with the substation interval and switch topology diagram. Display the real-time status of each switchgear model on the switch topology diagram according to the substation interval. At this time, the verification of switch position changes can be carried out. The switchgear model receives the remote control command. When there is a switch position change, the remote control point information and analog quantity information of the switchgear model are first verified, and the result is fed back after the verification is completed, and the switch position is changed. The topology diagram receives the verification result and changes according to the current status of the switch position. The verification of switch position changes can set batch tasks, which are automatically run by the program. For all switchgear models that have been completed with configuration, the verification of switch position changes is carried out one by one, and the result of each switch position change and the action completion time are recorded at the same time for subsequent query. As Figure 5 shown, it specifically includes:

[0094] S31 If the switchgear model receives the remote control command and there is a switch position change, the remote control point information and analog quantity information in the switchgear model are first verified, and the result is fed back after the verification is completed;

[0095] After receiving the switch position change signal, the switch model needs to be able to normally feedback the signal reception situation and its own switch point change. In the case of the association of the switch topology diagram, the switch topology diagram can correctly feedback the interval switch situation.

[0096] S32 The switch topology diagram receives the verification result and changes according to the current status of the switch position;

[0097] S33 For all switchgear models that have been completed with configuration, the verification of switch position changes is carried out one by one, and the result of each switch position change and the action completion time are recorded at the same time until the verification of all switchgear models is completed.

[0098] In the embodiment of the present invention, the switch topology diagram is strictly associated with the switchgear model. The change of the characteristic quantity of the switch model will be directly reflected on the switch topology diagram. Such a design can accurately and effectively grasp the change, so as to update the attribute information of the switch in time, avoid the need to check a large amount of data during verification, and improve the verification efficiency.

[0099] S4 Based on the substation interval information stored in the switch topology diagram, match and extract the Chinese names in the one-key sequence control background operation ticket, and generate a verification operation ticket according to the key information configured in the operation ticket.

[0100] In an embodiment of the present invention, based on the stored substation bay information: bay name, bay type, measuring and control equipment name, voltage level, the Chinese names in the one-key sequence control background operation ticket are matched and extracted, and the key information for configuring the operation ticket is obtained, including the operation ticket name, the operation ticket bay, the operation ticket execution sequence, the equipment involved in the operation ticket, and the operation ticket steps. A verification operation ticket is generated based on the obtained information. Among them, the information of the verification operation ticket corresponds strictly to the configuration content extracted from the SCD model file, including the measuring and control equipment name, the starting switch position, the switch position in the steps, the analog quantity information, the bay name to which it belongs, and the switch equipment type.

[0101] Specifically, the bay name is determined through the substation bay information. Using the bay name (usually a Chinese name plus a combination of English and numbers) as a keyword, the one-key sequence control background operation ticket is matched.

[0102] The switch names involved in the one-key sequence control background operation ticket are always added based on the bay English name. For example, the switches for bay 2M61 are 2M611, 2M613, 2M614, 2M615, etc. The operation ticket involved in the bay is determined by matching the English name, and the corresponding information is extracted.

[0103] According to the equipment names (names with letters and numbers) that conform to the electrical name rules involved in the matched operation ticket, the key configuration information such as the bay involved in the operation ticket, the operation ticket name, the switch equipment involved in each step, and the actions is determined.

[0104] In this embodiment, as shown in Figure 6 shown, it specifically includes:

[0105] S41 Obtain the corresponding substation bay attribute information according to the switch topology diagram, including: bay name, bay type, measuring and control equipment name, and voltage level;

[0106] The bay name is determined through the substation bay information. Using the bay name (usually a Chinese name plus a combination of English and numbers) as a keyword, the one-key sequence control background operation ticket is matched.

[0107] S42 Obtain the key information for configuring the operation ticket from the Chinese name of the one-key sequence control background operation ticket, including: operation ticket name, operation ticket bay, operation ticket execution sequence, equipment involved in the operation ticket, and operation ticket steps;

[0108] Because the switch names involved in the one-key sequence control background operation ticket are always added based on the bay English name. For example, the switches for bay 2M61 are 2M611, 2M613, 2M614, 2M615, etc. The operation ticket involved in the bay is determined by matching the English name, and the corresponding information is extracted.

[0109] Based on the device names (names with letters and numbers) that conform to the electrical name rules involved in the matched operation ticket, determine the intervals involved in the operation ticket, the name of the operation ticket, and the key configuration information such as the switch devices and actions involved in each step.

[0110] S43 Obtain the verified operation ticket based on the interval attribute information, the key configuration information of the operation ticket, and the current switch attribute information. The information of the verified operation ticket is not less than the name of the measurement and control device, the starting switch position, the switch position in the steps, the analog quantity information, the name of the interval to which it belongs, and the type of the switch device.

[0111] S5 Execute the verified operation ticket using the current switch device model switch state and the switch topology diagram to complete the one-key sequence control automatic verification.

[0112] In this embodiment, the information of the operation ticket for the one-key sequence control automatic verification is strictly associated with the switch device model and the switch topology diagram. During the execution of the verified operation ticket, the name of the operation ticket, the interval of the operation ticket, the execution order of the operation ticket, the devices involved in the operation ticket, the steps of the operation ticket, the remote control points of the switch device model, the analog quantity, the switch state, and the display of the switch topology diagram in the operation ticket all need to be consistent.

[0113] Furthermore, the verification of the present invention includes forward verification and reverse verification, that is, pre-verification and on-site verification. What is verified is that the test system itself can give correct feedback when the sequence control command configuration conforms to the remote control points of the on-site SCD model file, and can give correct error reports when it does not conform to the remote control points of the SCD model file. Thus, the correctness of the test system itself and the reliability of the communication function are ensured.

[0114] Specifically, in this embodiment, step S5 specifically includes pre-verification. Through the built-in simulation sequence control host in the system, according to the one-key sequence control background operation ticket, send sequence control commands. The one-key sequence control automatic verification module receives the commands, performs remote control point comparison, returns the remote control result according to the comparison result, and modifies the switch position state. The switch topology diagram nodes change correspondingly according to the change of the switch position and are displayed in real time. The analog quantity in the topology diagram changes correspondingly according to the preset logic. The simulation sequence control host judges the result of the sequence control step according to the returned remote control result and the change of the analog quantity, and proceeds to the next step or aborts with an error report. Complete the self-verification of all operation tickets, thereby ensuring the correctness and feasibility of each node of the configured topology diagram, the switch device model, the verified operation ticket, and the automatic verification part, and a large amount of debugging time can be saved in the actual on-site verification.

[0115] The simulation sequence control host in the present invention is an independent system, which can be integrated with the one-key sequence control test system in the same device. No additional device connection is required during pre-testing. When the test conditions cannot be provided on-site, the configuration data of the one-key sequence control test module can be pre-tested in advance.

[0116] Specifically, in this embodiment, asFigure 7 As shown, the method corresponding to pre-verification includes the following steps:

[0117] When the built-in analog sequence control host in S51 multiplexes and constructs the switch topological diagram, it extracts the switch device feature quantities and data, and stores them in the database of the analog sequence control host. The switch device feature quantities and data include: substation interval name, interval type, measurement and control device name, switch device name, switch device type, interval analog quantity, remote control point information, other feature quantities and change logic.

[0118] There is its own database configuration inside the analog sequence control host, and engineering backup can also be carried out if necessary. Each engineering backup can be regarded as the sequence control host of a different substation.

[0119] In S52, the analog sequence control host is directly connected to the actual sequence control host, and the sequence control host issues the sequence control command. When the one-key sequence control command starts, the analog sequence control host resets the initial position of the switch position according to the requirements of the verification operation ticket.

[0120] After the command in S53 is issued, the analog sequence control host receives the command, performs remote control point comparison, returns the remote control result according to the comparison result, and modifies the switch position state;

[0121] In S54, the analog sequence control host receives the remote control result, modifies the remote control point value in the database of the analog sequence control host, and changes the other feature quantities according to the preset logic. The corresponding switch topological diagram is also modified and changed according to the remote control result;

[0122] In S55, the analog sequence control host judges the result of the one-key sequence control step according to the returned remote control result and the change of the analog quantity, and then proceeds to the next step or aborts and reports an error.

[0123] Furthermore, step S5 in this embodiment further includes on-site verification. When performing on-site verification, the analog sequence control host temporarily disconnects the communication connection with the one-key sequence control automatic verification module, and the automatic verification module changes to receive the commands of the actual sequence control host. Execute the verification operation ticket to perform one-key sequence control automatic verification.

[0124] First, verify the switch state of the current switch device model, and synchronize the switch topological diagram according to the initial switch position. In the subsequent verification steps, the switch device model is strictly associated with the switch topological diagram, and the switch topological diagram reflects the current state of the switch model in real time.

[0125] Verify step by step according to the verification operation ticket steps. The analog sequence control host issues a sequence control command, and matches the remote control point information involved in the sequence control command with the information in the verification operation ticket. If the match is successful, the switch position in the switch device model changes, and the switch topological diagram changes.

[0126] After completing a single step, verify the interval analog quantity. If it is within the normal range, proceed to the next step of initial position verification.

[0127] During the automatic verification process, all verification operation ticket information, switch equipment model communication content, and switch topology diagram changes involved are automatically recorded. After all steps are completed, a verification report is generated based on the automatically recorded information in combination with the switch position change verification record. The report is automatically stored for future query.

[0128] As Figure 8 shown, the on-site verification specifically includes the following steps:

[0129] S5-1 Verify the switch state of the current switch equipment model and synchronize the switch topology diagram according to the initial switch position;

[0130] S5-2 In subsequent verification steps, the switch equipment model is real-time associated with the switch topology diagram, and the switch topology diagram reflects the current state of the switch model in real-time;

[0131] S5-3 Gradually verify according to the steps of the verification operation ticket. The simulation sequence control host issues a sequence control command, and matches the remote control point information involved in the sequence control command with the remote control point information in the verification operation ticket. If the match is successful, the switch position in the switch equipment model changes, and the switch topology diagram changes; the successful match standard is the same Chinese name of the switch equipment, the measurement and control equipment number, and the configured remote control point information value;

[0132] S5-4 After completing a single step, verify the interval analog quantity. If it is within the normal range, proceed to the verification of the initial position of the next step.

[0133] In summary, as Figure 9 shown, this method mainly involves the SCD model file. The SCD model file includes IED attribute classification and Chinese name, and deletes parameters such as manufacturer identification, model number, and interval number in the IED attribute classification. Obtain the switch equipment attributes from the IED attribute classification, and construct the switch equipment model from the switch equipment attributes. Obtain the switch topology diagram from the above-mentioned Chinese name, perform switch position change verification from the switch topology diagram and the switch equipment model, obtain the verification operation ticket from the Chinese name, perform one-key sequence control automatic verification on the switch equipment model, switch topology diagram, and verification operation ticket, and generate a verification report according to the automatic position change verification and one-key sequence control automatic verification. Among them, the verification operation ticket is obtained according to the Chinese name and operation ticket data.
