Description

Technical Field

[0001] The present invention relates to the technical field of intelligent substations, and in particular to an intelligent substation reconstruction and expansion configuration file calibrator and a calibration method thereof. Background Art

[0002] With the implementation of the State Grid Corporation's smart grid strategy, conventional substations are gradually being replaced by smart substations. Smart substations use a series of new technologies and equipment, such as information modeling, network communication, electronic transformers, and merging units, to achieve a high degree of data sharing and an improvement in the level of intelligence. The application of these technologies not only improves the operating efficiency and reliability of substations, but also lays the foundation for the comprehensive construction of smart grids.

[0003] However, the secondary system of smart substations brings new challenges to operation and maintenance due to its abstract information interaction process and the application of new equipment. Especially in terms of reliable operation of equipment, due to the technical complexity and the high correlation between equipment, once a problem occurs in a certain link, it may affect the operation of the entire substation. Therefore, for smart substations that have been put into operation, when they face the need for transformation or expansion, how to ensure the reliable operation of equipment and the stability of the system during the transformation or expansion process has become an urgent problem to be solved.

[0004] The renovation and expansion of smart substations is more complicated than that of conventional substations. In conventional substations, when a bay is renovated or expanded, only the secondary circuit of the renovated or expanded bay needs to be verified, and the secondary circuit of the non-renovated or expanded bay does not need to be verified. However, in smart substations, since the circuit configuration information is stored in the device process layer configuration file (such as SCD file), when renovating or expanding, the station control layer and process layer configuration files need to be re-exported from the SCD file and re-downloaded to the device. This process is not only cumbersome, but also prone to errors.

[0005] During the renovation and expansion process, how to define which devices need to re-download configuration files, as well as the modification content and impact scope of the configuration files, are important bases for formulating renovation and expansion plans. In particular, for busbar protection devices that span bays, their configuration files contain the circuit information of all bays. Once a problem occurs in the configuration file downloaded to the busbar protection device, it may affect the operation of all bays. However, there is currently no effective means to confirm whether the configuration information downloaded to the non-renovation and expansion bays in the device remains unchanged. Therefore, in addition to verifying the renovated or expanded bays, it is also necessary to verify the relevant secondary circuits of all non-renovation and expansion bays of the busbar protection.

[0006] In view of the above challenges and difficulties, it is particularly important to develop a configuration file calibrator for smart substation renovation and expansion. The calibrator can realize automatic verification and comparison of configuration files to ensure the correctness and consistency of configuration files during the renovation and expansion process. At the same time, it can also provide detailed verification reports and error prompts to help operation and maintenance personnel quickly locate and solve problems. This can not only improve the efficiency and accuracy of renovation and expansion work, but also reduce operation and maintenance costs and risks. Summary of the invention

[0033] Export SCD or CCD comparison reports to PDF format via the report module.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] The configuration file checker for smart substation renovation and expansion effectively solves the configuration file verification problem in the process of smart substation renovation and expansion, and improves the efficiency and reliability of operation and maintenance work through the combination of the following structures:

[0036] 1. Combination of operation panel and touch screen: The touch screen on the operation panel provides an intuitive user interface, allowing operation and maintenance personnel to directly input commands, view verification status and results, greatly simplifying the operation process and improving operation efficiency. At the same time, the combination of touch screen, indicator lights and operation buttons makes the status information of the equipment clear at a glance, which is convenient for operation and maintenance personnel to quickly judge the equipment status;

[0037] 2. Combination of interface and optical fiber module: The interface set on the side of the shell is used to connect relevant equipment in the smart substation, such as protection devices, merging units, etc., to achieve real-time data transmission. The optical fiber module is responsible for high-speed and stable data transmission to ensure the accuracy and integrity of data during the verification process. This combination enables the calibrator to obtain configuration file information in the substation in real time, providing data support for subsequent verification work;

[0038] 3. The control mainboard is the core component of the calibrator. It integrates multiple functional modules such as the acquisition module before and after the renovation and expansion, the secondary virtual circuit feature code extraction module, the secondary virtual circuit feature code comparison module and the report module. These modules work together. First, the acquisition module obtains the configuration file information before and after the renovation and expansion, and then the feature code extraction module is used to extract the feature code of the secondary virtual circuit. The feature code is then compared through the comparison module, and finally a calibration report is generated. This multi-module design makes the calibration process automatic and intelligent, greatly improving the accuracy and efficiency of the calibration.

[0039] 4. Combination of radiator and fan: Since the calibrator will generate a lot of heat during long-term operation, in order to ensure the stable operation of the equipment, a radiator and a fan are set in the shell. The radiator reduces the temperature of the equipment by increasing the heat dissipation area, while the fan accelerates the heat dissipation through forced convection. This combination effectively controls the temperature of the equipment and extends the service life of the equipment.

[0040] The device is cleverly packaged in an integrated, portable housing with a compact and ergonomic design, which is easy for maintenance personnel to carry and operate in different working environments. Indicator lights are set on the operation panel. These indicators serve as intuitive status display windows, which can instantly reflect the current working status of the device, power supply status, and connection status with other devices or systems and other key information. Users can quickly grasp the operating status of the device, so as to make accurate judgments and adjustments to ensure efficient and safe calibration work. This design not only improves the overall practicality of the device, but also greatly enhances the user experience.

[0041] In summary, the configuration file calibrator for smart substation renovation and expansion effectively solves the configuration file verification problem in the process of smart substation renovation and expansion through the organic combination of operation panel and touch screen, interface and optical fiber module, control main board and multiple modules, radiator and fan, battery and charging indicator light, and improves the efficiency and reliability of operation and maintenance work.

All other embodiments obtained by ordinary technicians in the field without making creative work based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0058] like Figures 1 to 11 As shown, it shows a specific embodiment of the present invention: Figures 1 to 11 As shown, the intelligent substation reconstruction and expansion configuration file checker disclosed in the present invention includes a housing 1, an operation panel is arranged above the housing 1, the operation panel includes a touch screen 101, an indicator light, and an operation button, the indicator light and the operation button are arranged on one side of the touch screen 101, the indicator light includes a hard disk indicator light 2, a charging indicator light 3 and an optical fiber indicator light 4, and the operation button includes a power switch key 5, a direction key 7, a confirmation key 6, a custom key F18, a custom key F29, and a custom key F310;

[0059] An interface is provided on the side of the housing 1, a speaker 19 is provided on the lower side of the housing 1, and a fan 20 and an antenna 21 are provided below the housing 1;

[0060] The housing 1 is provided with a keypad 102, an optical fiber module 103, a first adapter board 104, a second adapter board 105, a heat sink 106, a battery 107, and a control mainboard 108. The control mainboard 108 includes a collection module before and after renovation and expansion, a secondary virtual loop feature code extraction module, a secondary virtual loop feature code comparison module, and a reporting module.

[0061] Preferably, Figures 4 to 6 As shown, the interface includes a charging interface 11, a SIM interface 12, an HDMI display interface 13, a USB interface 14, a first network interface 15, an audio interface 16, a second network interface 17, and an optical fiber interface 18;

[0062] The charging interface 11 , SIM interface 12 , HDMI display interface 13 , USB interface 14 , first network interface 15 , and audio interface 16 are arranged on the left side of the shell 1 from top to bottom, and the second network interface 17 and optical fiber interface 18 are arranged on the upper side of the shell 1 .

[0063] These interfaces each play an important role in the intelligent substation renovation and expansion configuration file calibrator, and they are cleverly arranged on different sides of the shell to facilitate connection and operation while keeping the equipment neat and portable.

[0064] The charging port is used to power the calibrator, ensuring that the device can be continuously powered when used for a long time or working outside. It is set on the left side. The charging port usually does not need to be frequently plugged and unplugged. Setting it on the non-operating side where users are accustomed can reduce accidental touches and interference, and it is convenient to use the power adapter for charging; the SIM port is a SIM card slot for inserting a SIM card to achieve network connection or positioning function of the device; the HDMI display port is used to output the display content of the calibrator to an external display, so that the calibration results can be viewed on a larger screen or for demonstration. The HDMI port is usually used to connect external display devices. Placing it on the left side can easily connect to these devices while avoiding cable clutter; the USB port is used to connect Connect USB devices, such as U disk, mouse, keyboard, etc., to realize data import and export, device control or peripheral expansion. The first network interface is used to connect to the local area network (LAN) to realize communication and data exchange between the calibrator and other devices in the network; the audio interface is used to connect audio devices such as headphones and speakers to realize sound input or output, such as playing prompt sounds during the calibration process; the second network interface provides additional network connection options, which may be used for redundant connections, connections between different network segments or special network configurations; the optical fiber interface is used for high-speed data communication in smart substations. The optical fiber interface is usually used for special or advanced data transmission needs. Placing it on the upper side can easily connect optical fiber cables while avoiding interference with other commonly used interfaces.

[0065] In summary, the settings of these interfaces fully consider the user's operating habits, the portability and neatness of the device, as well as the functional characteristics and usage frequency of different interfaces.

[0066] Preferably, Figures 8 to 10 As shown, the output end of the battery 107 is connected to the control mainboard 108, the control mainboard 108 is electrically connected to the key board 102, the first adapter board 104, and the second adapter board 105, the optical fiber module 103 is connected to the first adapter board 104 and the second adapter board 105, and the optical signal is transmitted and converted through the first adapter board 104 and the second adapter board 105.

[0067] The battery, as the power supply unit of the device, is responsible for providing electrical energy to the entire system. Its output end is an interface connected to other components. Through this interface, the battery's electrical energy can be transmitted to other parts. The control motherboard is the control center of the entire system. It is responsible for receiving the battery's electrical energy and distributing it to other components as needed. The control motherboard contains a processor, a memory, and other control circuits. The keypad is an interface for users to interact with the device. Users can control the operation of the device by pressing keys. The first adapter board and the second adapter board are connecting components on the circuit board, which are used to transmit electrical signals or optical signals from one part to another. The optical fiber module is a component for transmitting optical signals. The optical fiber module can convert electrical signals into optical signals, or vice versa, to achieve high-speed data transmission. Through the first adapter board and the second adapter board, the optical fiber module can transmit optical signals from one part to another and convert between electrical signals and optical signals when necessary.

[0068] Preferably, Figures 8 to 10 As shown, the radiator 106 is an L-shaped radiator, which is arranged on the upper side of the control mainboard 108 .

[0069] The radiator is designed to be L-shaped according to the layout inside the shell. The heat pipes are connected in an L-shaped bend to form a compact and efficient heat dissipation frame, which is arranged around the heat dissipation element to form a semi-enclosed structure. This layout ensures that the heat generated by the heat dissipation element can be quickly and evenly transferred to the radiator, and then dissipated into the air through the large-area heat sink of the radiator.

[0070] Through the L-shaped design, the radiator can make more efficient use of space, increase the heat dissipation area, and at the same time guide the air flow to form a more efficient heat dissipation channel, which helps to quickly dissipate the heat generated by the heat dissipation component to the surrounding environment and maintain stable operation of the equipment.

[0071] Preferably, Figure 3 As shown, the antenna 21 adopts a WIFI+4G wireless transmission antenna. The antenna 21 adopts a WIFI+4G wireless transmission antenna. This antenna design combines two wireless communication technologies, WIFI and 4G, and has multiple advantages and application scenarios. In the substation expansion or temporary verification task, the network connection can be quickly established without waiting for the laying and debugging of the wired network, thereby speeding up the progress of the verification work.

[0072] The application of WIFI+4G wireless transmission antenna in the configuration file calibrator for smart substation expansion and reconstruction not only improves the flexibility and convenience of the equipment, but also ensures the reliability and stability of data transmission, while reducing costs and improving work efficiency. These advantages make the antenna an ideal choice for smart substation expansion and calibration work.

[0073] Preferably, Figures 1-2 As shown, the battery 107 is a 9000mAh / 11.1V lithium battery, and the touch screen 101 includes a 10.1-inch LED backlight LCD screen and a capacitive touch screen, and the resolution of the LCD screen is 1920×1200.

[0074] 9000mAh / 11.1V lithium battery has large battery capacity and long battery life, suitable for portable devices;

[0075] The 10.1-inch LED backlight LCD screen size is a medium-sized display screen suitable for portable devices. LED backlight means that the display screen uses LED as the backlight source. Compared with traditional CCFL backlight, LED backlight is more energy-efficient, thinner and has a longer lifespan;

[0076] The above parameters make this device a high-performance portable device with long battery life, high-quality display and user-friendly interactive interface.

[0077] Preferably, Figure 1 As shown, corner guards are arranged at the four corners of the housing 1, and the material of the corner guards is PVC.

[0078] Corner guards are provided at the four corners of the housing 1, and PVC (polyvinyl chloride) is specially selected as the material of the corner guards. The corners of the housing are often the most vulnerable to collision and impact. After installing the PVC corner guards, the impact resistance of these areas can be significantly enhanced, effectively preventing damage or deformation of the housing caused by accidental collision, thereby extending the service life of the device.

[0079] Preferably, Figure 4 As shown, the first network interface 15 and the second network interface 17 adopt the RJ45 adaptive network port standard interface. The RJ45 interface is a widely used standardized network interface, which complies with the IEEE 802.3 standard and is the most common interface form of Ethernet. This standardized design ensures the interoperability and compatibility between devices of different manufacturers and models. In the process of smart substation renovation and expansion, configuration file verification is an important link. By connecting the calibrator to other devices in the network (such as servers, workstations, etc.) through the RJ45 interface, remote verification and updating of configuration files can be achieved, thereby improving work efficiency and accuracy.

[0080] Preferably, Figure 3As shown, the lower surface of the housing 1 is provided with anti-slip grooves. The design of the anti-slip grooves also takes into account the user experience. When operating the calibrator for a long time, if the device is easy to slide, it will not only affect the operating efficiency, but also increase the user's fatigue. The design of the anti-slip grooves can effectively reduce such unnecessary sliding, allowing users to focus more on the calibration work itself, thereby improving overall work efficiency and satisfaction.

[0081] The calibration method of the configuration file calibrator for smart substation renovation and expansion is as follows:

[0082] Step 1: Create a project

[0083] The user logs in to configure the substation management project, including voltage level, address, and substation name;

[0084] Step 2: Obtain the substation configuration files and busbar configuration files before and after the reconstruction and expansion, using step a or step b

[0085] a. Before the expansion and renovation, the first network port of the device is connected to the background configuration network port of the smart substation through a network cable, and the second network port of the device is connected to the bus differential protection configuration network port of the smart substation through a network cable. The network segment IP and subnet mask are set, and the substation configuration file SCD file and bus differential protection configuration file CCD file before the expansion and renovation are obtained through the acquisition module before and after the expansion and renovation;

[0086] After the expansion and renovation, the first network port of the device is connected to the background configuration network port of the smart substation through a network cable, and the second network port of the device is connected to the bus differential protection configuration network port of the smart substation through a network cable. The network segment IP and subnet mask are set, and the substation configuration file SCD file and bus differential protection configuration file CCD file after the expansion and renovation are obtained through the acquisition modules before and after the expansion and renovation;

[0087] b. Use a dedicated U disk for the power system to connect the USB interface 14 of the device, and obtain the shared configuration files before and after the expansion through the acquisition module before and after the expansion;

[0088] Step 3: Extraction of secondary virtual circuit feature code

[0089] According to the model and description of the secondary virtual circuit configured in the SCD file, the secondary virtual circuit feature code extraction module extracts the type characteristics of the circuit, matches and compares with the rule base, and checks whether the circuit connection is complete and correct; the DOM model is used to parse the SCD to generate feature codes before and after the configuration description file;

[0090] Generate the characteristic code of CCD configuration file;

[0091] Step 4: Comparison of secondary virtual circuit signature codes

[0092] The secondary virtual circuit feature code comparison module is used to compare the feature codes generated by the configuration description files before and after the reconstruction and expansion, and the feature codes of the mother difference configuration file CCD file are compared to determine whether the secondary virtual circuits are consistent;

[0093] Step 5: Report export query

[0094] Export SCD or CCD comparison reports to PDF format via the report module.

[0095] like Fig.11As shown, the present invention mainly extracts the characteristic codes of the configuration description file and the mother difference configuration file, and then compares the characteristic codes, which is also the most important part of the present invention. The present invention mainly solves the problem of studying the method of calculating the characteristic code of each device process layer by extracting the mother difference configuration file of the device; analyzing the difference characteristics of the new and old check codes before and after the renovation and expansion, and studying the method of automatically dividing the equipment types according to the difference; extracting and comparing the configuration description file (SCD file) before and after the renovation and expansion. For the SCD configuration of the newly built smart substation, the design institute provides the virtual terminal contact table, the equipment manufacturer provides the ICD file, and the system integrator configures the communication parameters, virtual circuit connections and private properties of the entire station device through the system configurator to generate an SCD file to meet the needs of the site. For the SCD configuration process of the smart substation renovation and expansion, the design institute provides the virtual terminal contact table and related drawings for renovation and expansion, the operation and maintenance or dispatching department provides the SCD file, the system integrator imports the SCD through the system configuration tool, and configures the SCD file for renovation and expansion according to the requirements. For the extraction of SCD feature codes, the SCD configuration file uses the SCL language, and the SCL language should follow the XML syntax rules. The inspection of the secondary system function loop can be carried out in a progressive manner, and the correctness of the interval, device, and function can be checked. Taking line protection as an example, the complete logical closed loop includes analog and switch quantity sampling, protection tripping action output and other loops. The correctness of the specific loop connection: According to the model and description of the secondary virtual loop configured in the SCD file, the type characteristics of the loop are extracted, matched and compared with the rule base, and the loop connection is checked to be complete and correct. The DOM model is used to parse the SCD. First, each intelligent device is retrieved to extract its basic information such as its order and configuration. Then, Inputs are obtained step by step from IED to LD, the basic information of each IED and the LD information of its subordinate logical devices are obtained, and an IED object List link list is constructed. From the Inputs node of each LD, obtain the virtual connection information under the LD, form the virtual terminal number of the output end, and store it in the virtual connection linked list of the LD. For each connection object, the input virtual terminal references the internal connection address (intAddr) and the newly formed output virtual terminal number, and searches for the corresponding local LN and the sending device to send the LN to obtain the corresponding input and output virtual terminal descriptions, and generate the feature codes before and after the configuration description file. By comparing the feature codes generated by the configuration description files before and after the expansion, it is determined whether the secondary virtual circuit is consistent.

[0096] Extract and compare the mother differential configuration file before and after the reconstruction and expansion. First, grab the configuration file, generate the corresponding interface according to the mother differential manufacturer (the interface of each manufacturer is different), and the user fills in the corresponding parameter information, parses the interface content, generates the config.xml file, and puts it in the same directory as the mother differential manufacturer's executable file, and calls the mother differential manufacturer's executable program (grab the configuration file ReadCfg.sh). The mother differential manufacturer's executable program starts to execute and parse config.xml. To be compatible with the previous version, it is necessary to first parse config.xml. <interface>

[0097] If it is 1, call up the original interface program and execute it. If it is 0, go to the next step. Parse the parameter information in the XML file, and then perform corresponding operations according to the parameter information to directly generate the result. Get the front and back files of the mother difference configuration file, and then compare the files. Comparison process: Calculate the feature code of the mother difference configuration file, including the feature code of the mother difference sending GOOSE and the process layer configuration feature code of each IED device associated with the mother difference.

[0098] (1) The mother difference sends the corresponding configuration information of the GOOSE feature code CCD configuration file under the GOOSPUB node, and calculates and sends the feature code according to the rules;

[0099] (2) The mother differential receiving control obtains the configuration information under the GOOSESUB and SVSUB nodes of the CCD configuration file;

[0100] (3) The receiving control extracts the IEDName under the GOOSESUB node, and the path is IED / GOOSESUB / GOCBref / ConnectedAP / iedName.

[0101] (4) The receiving control extracts the IEDName under the SVSUB node; the path is IED / SVSUB / SMVCBref / ConnectedAP / iedName.

[0102] (5) Add the IEDNames obtained under the GOOSESUB and SVSUB nodes to the IEDNameList linked list in turn, remove the IEDName elements with the same name, and obtain a final IEDNameList linked list that does not contain duplicate IEDNames. The final IEDNameList linked list is used as a total reference to compare the differences between the IEDNames before and after the renovation and expansion.

[0103] (6) According to the IEDName in IEDNameList, process each IED information separately. Extract the structure data field in the GOOSESUB control block and SVSUB control block containing the IEDName, store and calculate the signature code to obtain the signature code for each IED as the basis for comparison.

[0104] (7) Based on the CRC of the sent GOOSE and the CRC of each IED, the feature code of the CCD configuration file is finally generated.
