Description

Technical Field

[0001] The present invention relates to the technical field of intelligent substation automation, and more particularly to a configuration-free testing method and device for a dynamic mold system for expansion and reconstruction of cross-bay equipment. Background Art

[0002] In smart substations, relay protection communication information is reflected in configuration files. The SCD file describes the communication between all station-wide devices, encompassing all intelligent IED models, including information at the substation, bay, and process levels, as well as information exchanged between different IEDs. This information model establishes communication relationships and simplifies physical circuit connections. The next-generation autonomous substation proposes standardized device modeling using a model-based standardization technique and the principle of maximization. This includes standardized modeling for acquisition and execution units, transformer protection, busbar protection, line protection, and circuit breaker protection. The SCD file, integrated with standardized maximization models of these devices, enables standardized pre-configuration of CCD files for cross-bay relay protection information during future renovation and expansion phases, enabling a configuration-free solution for cross-bay relay protection. This eliminates the risk of inadvertent modifications to non-renovation and expansion bays by requiring only the bays being expanded or renovated, eliminating the need to revalidate other operating bays. This reduces the workload and power outages during commissioning and acceptance. Therefore, how to verify the correctness of the virtual circuit after the expansion and reconstruction of cross-interval equipment and the standardization of the model file is a difficult problem we are facing now. Summary of the Invention

[0019] Optionally, check the protection device's own verification results, including:

[0020] If the protection device operation light is on normally and there are no alarms related to the device configuration file and link, it is determined that the protection device self-verification is successful. Otherwise, modify the device configuration file or physical link to re-verify itself.

[0021] Optionally, the movable mold system is modified and expanded, and a fault simulation is performed on the modified and expanded movable mold system to determine the configuration-free test results of the modified and expanded movable mold system, including:

[0050] Exemplary Methods

[0051] Figure 1 This is a flow chart of a configuration-free testing method for a dynamic mold system for expansion and reconstruction of a cross-interval device provided by an exemplary embodiment of the present invention. This embodiment can be applied to electronic devices, such as Figure 1 As shown, the configuration-free testing method 100 for renovating and expanding a dynamic mold system across a spaced device includes the following steps:

[0052] Step 101, constructing the primary system and secondary system of the dynamic mold system for cross-interval equipment renovation and expansion without configuration test;

[0053] Step 102: configuring an SCD file for the primary system according to the principle of long-term maximum configuration;

[0054] Step 103: Configure the secondary system through the SCD file and perform a fault simulation on the dynamic model system to verify the correctness of the virtual circuit;

[0055] Step 104 , if the verification is passed, the dynamic mold system is modified and expanded, and a fault simulation is performed on the dynamic mold system after the modification and expansion and the correctness of the virtual circuit is verified to determine the configuration-free test result of the modified and expanded dynamic mold system.

[0056] Specifically, the present invention can truly simulate the system operation state and fault state by building a dynamic model test system, can truly verify the correctness of the virtual circuit, and verify the reliability of the cross-interval protection device configuration file that has been running during the renovation and expansion process, so as to reduce the scope of power outages and ensure the reliable operation of the smart substation.

[0057] By building a dynamic model test system and real secondary equipment networking, the actual operating status of the site can be reflected to the greatest extent. By simulating system faults in the dynamic model test system, both the performance of the protection device and the correctness of the virtual circuit can be verified. The correctness of the virtual circuit for the expansion and reconstruction of cross-bay equipment can be truly verified, laying a solid foundation for the implementation of a new generation of autonomous and controllable substations.

[0058] The present invention proposes a dynamic model system and method for configuration-free testing of cross-interval equipment modification and expansion. By building a configuration-free testing system for cross-interval equipment modification and expansion, the correctness of the virtual circuit after the cross-interval equipment modification and expansion is tested.

[0059] The present invention proposes a dynamic mold system and method for cross-interval equipment renovation and expansion without configuration testing, which mainly consists of the following:

[0060] 1) The dynamic mold system for cross-interval equipment expansion and reconstruction without configuration test is mainly divided into primary system and secondary system.

[0061] (1) The primary system is mainly composed of power supply elements, interval elements and fault elements.

[0062] (2) The power supply components include an infinity and a generator, which are used to provide power to the dynamic mold system.

[0063] (3) The interval elements include busbar intervals, bus-coupler intervals, segmented intervals, line intervals, and transformer intervals. Each interval is composed of switches, knife switches, voltage transformers, and current transformers, and can provide voltage, current, switching value and other signals for the secondary system. The primary system of the dynamic model system can increase or decrease the corresponding line intervals and transformer intervals according to the needs of reconstruction and expansion.

[0064] (4) The fault element can be set at any point in the primary system to simulate system faults. The fault phase, fault time, transition resistance, etc. can be selected for each fault point.

[0065] (5) The secondary system mainly includes protection devices, data acquisition and execution units, main and auxiliary integrated monitoring hosts, integrated application hosts, and switches. The secondary system is built in the same way as in actual smart substations. The integrated application host includes SCD configuration and online operation and maintenance management tools, which are used for SCD configuration, verification, configuration file export, and online download.

[0066] 2) The configuration-free test method for cross-bay equipment expansion and renovation mainly includes the following steps:

[0067] (1) The SCD file is configured according to the principle of long-term maximization configuration, which includes busbar intervals, bus-coupler intervals, section intervals, line intervals, and transformer intervals. Each interval includes protection devices and acquisition execution units. After the configuration is completed, the SCD file is checked for model normativeness through the SCD configuration and online operation and maintenance management tool. If the check is passed, the next step is carried out. If the check is wrong, the configuration is returned to continue.

[0068] (2) Export the configuration files of the protection device and the acquisition execution unit through the SCD configuration and online operation and maintenance management tool. After exporting the device configuration file, use the SCD configuration and online operation and maintenance management tool to verify the consistency of the configuration file with the SCD file. If the verification is passed, proceed to the next step. If the verification is wrong, return and re-export.

[0069] (3) Download the configuration file to the protection device configuration directory through the integrated application host, restart the protection device, and check the protection device self-verification results. If the protection device operation light is normally on and there are no configuration file and link-related alarms, it is considered that the protection device self-verification is successful. Otherwise, the configuration file or physical link needs to be modified.

[0070] (4) Import the SCD file to the main and auxiliary integrated monitoring host and the comprehensive application host to configure the alarm signal.

[0071] (5) Simulate the system faults at different fault points in the dynamic model system to check the action information of the protection device and the alarm information of the protection device in the main and auxiliary integrated monitoring host, and verify the correctness of the virtual circuit of this interval and across intervals. The system faults include metallic faults inside and outside the area and circuit breaker failure.

[0072] (6) In the case of expansion, the line interval of the primary system is increased, including switches, current transformers, voltage transformers, and protection devices and data acquisition execution units are added to the secondary system. In the case of renovation, the protection devices and data acquisition execution units of the secondary system are modified or upgraded.

[0073] (7) Update the IED model of the original SCD file through the integrated application host. The IED name, virtual circuit, and communication parameter configuration remain unchanged. Verify the new version of the SCD file and the newly added interval configuration file. Download and verify the newly added interval protection device and acquisition execution unit configuration. Put the interval receiving pressure plate of the cross-interval protection device into operation.

[0074] (8) Simulate system failures at different points in the dynamic model system and at fault points within newly added intervals, check the action information of the protection device and the alarm information of the protection device in the main and auxiliary integrated monitoring host, and verify the correctness of the newly added intervals and cross-interval virtual circuits. Faults include metallic faults inside and outside the zone and circuit breaker failures.

[0075] (9) If the cross-interval protection device operates correctly, it means that the cross-interval protection device configuration-free test is successful. If the cross-interval protection device operates incorrectly, it means that the cross-interval protection device configuration-free test has failed.

[0076] In addition, a 220kV smart substation dynamic model test system was built, as shown in the system diagram. Figure 2 As shown, 3W, 12G, and 14G are power supply components. 3W is an example of infinity, and 12G and 14G are examples of generators. CT* is an example of a current transformer, PT* is an example of a voltage transformer, BKS* is an example of a switch, and FD* is an example of a fault point. The system includes busbar bays (I bus and II bus), transformer bays (U9 and U14), bus coupler bays (bus coupler 1 and bus coupler 2), section bays (section 1 and section 2), and line bays (U1, U7, U13, and U16). U7 and U9 are planned bays for the long term and will not be constructed for the time being. Construction will be carried out during subsequent renovations and expansions.

[0077] Secondary system connection diagram as shown Figure 3 As shown in the figure, the dynamic model test system provides voltage, current, and switching values ​​to the acquisition and execution unit. This unit converts the analog values ​​into digital values ​​and inputs them into the protection device. The protection device is connected to the main and auxiliary integrated monitoring host and the integrated application host via the station control layer network. Laboratory recording is used to monitor the protection device's behavior and the accuracy of the analog output.

[0078] The SCD configuration and online operation and maintenance management tool is deployed on the comprehensive application host, and can be used to download SCD configuration and configuration files online.

[0079] Configure the SCD file according to the long-term maximization, configure all interval contents, among which the interval contents of U7 and U9 (including virtual terminal information and communication parameter information) are copied according to the similar intervals of U1 and U14. For the configuration of busbar protection virtual circuit, see Figure 4Use the SCD configuration and online operation and maintenance control tools to perform model compliance verification on the SCD file. If the verification passes, proceed to the next step. If the verification fails, return to continue configuration.

[0080] Export the configuration files of the equipment in the bus bay, bus-coupler bay, section bay, line bay (excluding U7), transformer bay (excluding U9), and cross-bay equipment (busbar protection). Use the SCD configuration and online operation and maintenance management tool to verify the consistency of the configuration files with the SCD file. If the verification is passed, proceed to the next step. If the verification is incorrect, return and re-export.

[0081] Download the configuration file online to the protection device configuration directory through the integrated application host and restart the protection device.

[0082] Simulate the normal operation of the dynamic model system, check the alarm information of the protection device and the real-time status of voltage and current, preliminarily judge the status of the virtual circuit of the equipment within and across the intervals, and check the action behavior of the protection device by simulating the metallic faults and failure faults inside and outside each interval such as FD1, FD4, FD5, FD6, FD7, FD11. If the action behavior of the protection device is consistent with the expectation, it is determined that the virtual circuit connection is correct. Otherwise, the connection is wrong and modification and debugging are required.

[0083] Simulate the expansion of line bay U7, connecting components such as BKS3, CT13, and FD6. Expand transformer bay U9, connecting components such as BKS4, CT67, and FD2. Add corresponding transformer protection, line protection, and acquisition and execution units to the secondary system. Update the IED model in the original SCD file, while maintaining configurations such as virtual circuits and communication parameters. Verify the new SCD file and the configuration files for the newly added bays (U7 and U9). Download and verify the protection devices and acquisition and execution unit configurations for the newly added bays (U7 and U9). Then, commission the receiving software boards for the busbar protection devices in bays U7 and U9.

[0084] The dynamic model test system was put into U7 and U9 intervals to check the cross-interval bus protection, the alarm information of the newly added interval protection device, and the real-time status of voltage and current, and preliminarily judge the virtual circuit communication status.

[0085] Simulate a system fault at fault points FD6 and FD2, including a metallic fault and a long-term circuit breaker failure. Check the behavior of the newly added line and transformer protection devices and the busbar protection devices. If the protection device behavior is consistent with expectations, the virtual circuit connection is correct. Otherwise, the connection is incorrect.

[0086] Therefore, the present invention adopts fully physical dynamic model equipment and real protection devices. Compared with using simulation software to simulate virtual circuits and devices, it can more completely and realistically reflect the operating status of the virtual circuit under the actual operating state and fault state of the actual smart substation, effectively reduce the errors that may be caused by human operation, and effectively verify the correctness of the virtual circuit.
