[0003] Intelligent substation is the development trend of power technology. The traditional substations in the past will also be transformed into intelligent substations through transformation. Due to the actual working status of each substation, it is impossible to realize the overall transformation of the substation by shutting down the whole station.

[0004] However, compared with the conventional solution, the new transformation plan has different network architecture and communication networking methods. That is, the newly transformed interval is optical communication (goose method), while the public protection equipment that communicates with it (such as busbar protection) is traditional electrical signal method. The newly transformed equipment and the old public protection equipment cannot communicate directly. Summary of the invention

[0027] Embodiment 1

[0028] Figure 1 A flowchart of a method for intelligent transformation of a substation is provided for the first embodiment of the present invention. This embodiment is applicable to the case of realizing communication between a traditional substation and an intelligent substation. The method can be executed by an intelligent transformation device for a substation. The intelligent transformation device for a substation can be implemented in the form of hardware and / or software. The intelligent transformation device for a substation can be configured in an electronic device. Figure 1 As shown, the method includes:

[0029] S101. Determine a target interval line in a substation to be transformed, and determine conventional equipment and transformation equipment in the target interval line.

[0030] The substation to be transformed may refer to a substation to be transformed into an intelligent one. The target interval line may refer to an interval line that has not been transformed into an intelligent one, or an interval line to be transformed into an intelligent one.

[0031] For example, the conventional equipment may include but is not limited to conventional main transformer protection, conventional operation box, measurement and control device and switch mechanism box. The modified equipment may include but is not limited to intelligent busbar protection and intelligent terminal.

[0032] Specifically, according to the transformation planning requirements, the target interval route in the substation to be improved can be determined, and then the target interval route can be analyzed and processed to determine the conventional equipment and transformation equipment in the target interval line.

[0033] Exemplarily, the step of determining a target interval line in a substation to be transformed includes:

[0034] Obtain a system configuration file corresponding to the substation to be transformed; analyze and process the system configuration file to determine the target interval line in the substation to be transformed.

[0035] The system configuration file may refer to a substation-wide SCD (Substation Configuration Description) file of the substation.

[0036] Specifically, the target interval lines that have not yet been intelligently transformed are selected from the obtained system configuration files.

[0037] Exemplarily, the process of acquiring the system configuration file may be to collect ICD (IED capability description) models of traditional protection devices and measurement and control devices provided by various manufacturers, and generate an SCD (system configuration description) full-station system configuration file based on the collected ICD models.

[0038] S102: deploy a target intelligent interface device corresponding to the target interval line between the conventional device and the modified device, and perform communication between the conventional device and the modified device based on the target intelligent interface device.

[0039] Among them, the target intelligent interface device can be used to connect the electrical signals from the secondary equipment of the conventional station to the process layer network of the transformation equipment in the form of optical signals. It should be noted that the target intelligent interface device adopts an aluminum alloy chassis that complies with the IEC60297-3 standard, an integral panel, and a plug-in functional component with locking. The plug-ins are all rear plug-in, and the device is installed in an overall embedded horizontal installation and rear wiring.

[0040] Exemplarily, the target intelligent interface device includes at least an operation indication function, an alarm indication function, a maintenance indication function, a GOOSE abnormality indication function, an optocoupler power failure indication function, an output abnormality indication function, an input abnormality indication function, a mother differential action indication function and a branch action indication function.

[0041] Figure 2 is a functional schematic diagram of a target intelligent interface device provided by an embodiment of the present invention, such as Figure 2 As shown, the target intelligent interface device includes an operation indicator light, an alarm indicator light, a maintenance indicator light, a GOOSE abnormal indicator light, an optocoupler power failure indicator light, an output abnormal indicator light, an input abnormal indicator light, a bus differential action indicator light and a branch action indicator light. It should be noted that the operation indicator light is green when the device is normal and goes out when the device is abnormal. The alarm indicator light goes out when the device is normal and goes out when the device is abnormal. The maintenance indicator light is green when the maintenance pressure plate is put into operation and goes out when the maintenance pressure plate is withdrawn. The GOOSE abnormal indicator light is red when the GOOSE communication is interrupted or abnormal, and goes out when it is normal. The optocoupler power failure indicator light is red when the remote signal power supply monitoring input is low level, and goes out when it is high level. The output abnormal indicator light is red when the output plug-in self-test is abnormal, and goes out when it is normal. The input abnormal indicator light is red when the input plug-in self-test is abnormal or the input is abnormal, and goes out when it is normal. The bus differential action indicator light is red when any output contact of the bus differential protection is actuated, and goes out when it is normal, and the action is maintained. The branch action indicator light is red when the mother differential action + branch action is in progress. When normal, it is off and the action is maintained.

[0042] Figure 3 FIG. 1 is a working principle diagram of the target intelligent interface device provided by an embodiment of the present invention. Figure 3 As shown, the target intelligent interface device sends and receives all types of signals, so that the device can adapt to traditional equipment or intelligent equipment at the same time. Specifically, the target intelligent interface device is responsible for the hard contact / GOOSE conversion bidirectional conversion between the conventional bay and the intelligent bus protection. The intelligent interface device has the dual CCD coexistence capability of the bay protection and the circuit breaker intelligent terminal, and can virtualize the bay protection and the circuit breaker intelligent terminal to communicate with the intelligent bus protection GOOSE.

[0043] Exemplarily, the configuration process of the target intelligent interface device includes: collecting system configuration files corresponding to the substation to be transformed; based on the conventional equipment in the target interval route, tailoring the system configuration files to obtain device configuration files corresponding to the conventional equipment; importing the device configuration files into the target intelligent interface device for configuration processing.

[0044] The device configuration file may refer to configuration information corresponding to regular devices in the target interval route.

[0045] Specifically, the system configuration files corresponding to the substation to be transformed are collected in advance, such as CID files, which carry instantiation information and can interpret the received messages to obtain the control commands sent by the intelligent device. Since the target intelligent interface device is installed between the busbar protection and the transformed intelligent device, the target intelligent interface device is only responsible for translating the interactive information between the busbar protection and a certain interval. Therefore, the target intelligent interface device will cut the system configuration file of the busbar protection according to the settings, and only retain the device configuration file between the transformed intelligent device.

[0046] Exemplarily, the target intelligent interface device includes an optical module, an electrical module and a photoelectric conversion module; wherein the optical module is used to receive or send an optical signal. The electrical module is used to receive or send an electrical signal. The photoelectric conversion module is used to store device interaction information corresponding to the target interval route, and convert the optical signal into an electrical signal or convert the electrical signal into an optical signal based on the device interaction information.

[0047] Exemplarily, the communication between the conventional device and the modified device based on the target intelligent interface device includes:

[0048] By means of the optical module, receiving the communication optical signal sent by the transformation device and sending the communication optical signal to the photoelectric conversion module, or receiving the communication optical signal sent by the photoelectric conversion module and sending the communication optical signal to the transformation device;

[0049] By means of the electrical module, receiving the communication electrical signal sent by the conventional device and sending the communication electrical signal to the photoelectric conversion module, or receiving the communication electrical signal sent by the photoelectric conversion module and sending the communication electrical signal to the conventional device;

[0050] Through the optoelectronic conversion module, based on the pre-stored device interaction information, the communication optical signal is converted into a communication electrical signal, and the communication electrical signal is sent to the electrical module; or, based on the pre-stored device interaction information, the communication electrical signal is converted into a communication optical signal, and the communication optical signal is sent to the optical module.

[0051] It should be noted that the target intelligent interface device is mainly composed of an optical module (capable of sending and receiving optical signals), an electrical module (capable of sending and receiving electrical signals) and a photoelectric conversion module (capable of converting electrical signals and optical signals into each other).

[0052] Exemplarily, the work flow of the target intelligent interface device is described by taking receiving an optical signal and converting it into an electrical signal as an example, and the process of converting the received electrical signal into an optical signal is the opposite.

[0053] After a certain interval line of a conventional substation is transformed into an intelligent one, the interval intelligent device communicates with the optical module of the target intelligent interface device through optical fiber, and the optical module receives optical signal messages according to the IEC61850 standard.

[0054] The photoelectric conversion module should download the CID file of the bus protection in advance. The file contains instantiation information and can interpret the received message to obtain the control command sent by the intelligent device. Since this device is installed between the bus protection and the modified intelligent device, it is only responsible for translating the interaction information between the bus protection and a certain interval. Therefore, this device will cut the CID file of the bus protection according to the settings and only retain the interaction information with the modified intelligent device. The photoelectric conversion module sends the interpreted command to the electrical module for output according to the set mapping relationship.

[0055] The electrical module closes or disconnects the relevant nodes according to the command, thereby realizing the output of electrical signals, that is, sending the optical signal of the modified interval to the bus protection, thereby realizing the start-up, failure, locking and other operations of the bus protection.

[0056] It should be further explained that in the transformation and upgrading of a single bay, all the electrical signals of all bay devices are connected to the intelligent interface device, and the equipment is connected to the process layer switch through the intelligent interface device. No other protection needs to be modified during the transformation of a bay and after the commissioning. The final SCD can be compiled directly at the beginning of the transformation, and no modification is required during the transformation. In the early stage of the transformation, the cable communication of the traditional hard connection can be directly converted to the optical fiber communication of the intelligent device. The system topology is simple, and a smooth transition of the intelligent transformation of the substation can be achieved. In addition, the intelligent interface device is suitable for equipment of different standards and models, and can be reused to reduce the cost of the transformation project.

[0057] The technical solution of the embodiment of the present invention determines the target interval line in the substation to be transformed, and determines the conventional equipment and the transformed equipment in the target interval line. A target intelligent interface device corresponding to the target interval line is arranged between the conventional equipment and the transformed equipment, and communication between the conventional equipment and the transformed equipment is performed based on the target intelligent interface device, which solves the problem that the transformed equipment and the old conventional equipment cannot communicate directly, so that the intelligent transformation can be carried out smoothly without affecting the normal operation of the power grid.
