[0033] Embodiment 1

[0034] Figure 1 The first embodiment of the present invention provides a flow chart of a configuration method for smart substation expansion and reconstruction. This embodiment is applicable to the case of parameter configuration of smart substations in expansion and reconstruction scenarios. The method can be executed by a configuration device for smart substation expansion and reconstruction. The configuration device for smart substation expansion and reconstruction can be implemented in the form of hardware and / or software. The configuration device for smart substation expansion and reconstruction can be configured in an electronic device. Figure 1 As shown, the method includes:

[0035] S110. Acquire message interaction information between the busbar interval and the line interval of the smart substation; the line interval includes: a basic line interval and a reconstruction and expansion line interval.

[0036] Among them, in the power system, the interval refers to a protected sub-section that separates some closely connected parts of the substation with certain common functions. The power interval can manage the power supply of the power equipment in a unified manner, thereby improving the overall safety of the system, and various equipment can operate independently, and make the inspection and maintenance of the equipment more convenient. The busbar interval is the interval for the busbar, which can also be called busbar protection; the line interval is the interval for the outgoing or incoming line, which can also be called line protection. The line interval can include: basic line interval and modified and expanded line interval. The basic line interval refers to the line interval that is constructed or put into operation during the basic construction of the smart point power station. The modified and expanded line interval is a line interval that is newly created in the later expansion process or needs to be modified or replaced during the operation and maintenance process relative to the basic line interval. The busbar interval has a direct correlation with the modified and expanded line interval.

[0037] During the operation of the smart substation, the busbar bay and the line bay interact continuously to realize the transmission operation of the smart substation, thereby generating interactive signals between the busbar bay and the line bay.

[0038] S120: Determine the standardized virtual terminals of each intelligent electronic device and the virtual circuits formed between each intelligent electronic device and the virtual terminals according to the message interaction information.

[0039] Among them, intelligent electronic devices (IEDs) are the basic elements of smart power stations, providing the detection, measurement, protection and control functions required by the power grid system. Virtual terminals describe the input and output signal connection points of intelligent electronic devices (which can be referred to as IEDs for short), and are used to identify the secondary circuit signals of the process layer, the interval layer and the connection between them. Standardized virtual terminals can avoid semantic confusion and are the basis for realizing non-stop transmission operations.

[0040] In this embodiment, the intelligent electronic device of the bus bay includes: a bus protection device, a bus merging device, and a bus intelligent terminal; the intelligent electronic device of the line bay includes: a line protection device, a line merging device, and a line intelligent terminal. The virtual terminal of the intelligent electronic device includes: at least one of a GOOSE publishing end virtual terminal, a GOOSE subscription end virtual terminal, a SV publishing end virtual terminal, and a SV subscription end virtual terminal.

[0043] S130: For each intelligent electronic device, configure the message communication parameters of the intelligent electronic device according to the virtual terminal associated with the virtual circuit.

[0044] The message communication parameters of the intelligent electronic device include: GOOSE message communication parameters and SV message communication parameters. GOOSE message communication parameters are communication parameters contained in the message sent by the GOOSE virtual terminal; SV message communication parameters are communication parameters contained in the message sent by the SV virtual terminal.

[0046] S140: Generate a pre-configuration file according to the information of each virtual terminal of the intelligent electronic device and each message communication parameter.

[0047] The pre-configuration file includes: the configuration information required for the bus bay, the configuration information required for the basic line bay, and the configuration information required for the reconstruction and expansion of the line.

[0048] In this embodiment, during the infrastructure construction stage, the information of the busbar intervals involved in the reconstruction and expansion of the line and the virtual terminal information and message communication parameters involved in other basic line intervals are included in the pre-configuration file. During the reconstruction and expansion stage, there is no need to reconfigure the virtual terminals involved.

[0049] S150. Use a pre-configuration file to configure the communication parameters of the busbar interval and the basic line interval in the infrastructure construction stage of the smart substation, and configure the communication parameters of the reconstruction and expansion line interval in the reconstruction and expansion stage of the smart substation.

[0050] In this embodiment, after the pre-configuration file is generated, the communication parameters of the bus bay and the basic line bay are configured in the infrastructure stage of the smart substation. In the renovation and expansion stage after the smart substation is put into use, since the subscription of the virtual terminals of the renovation and expansion bay has been completed in the infrastructure stage, there is no need to perform power outage transmission operations on the bus bay and the basic line bay, and the configuration file is modified to subscribe to the virtual terminals of the renovation and expansion line bay. It is only necessary to generate the CCD / CID file of the renovation and expansion line bay according to the pre-configuration file and download it to each IED of the renovation and expansion line bay to realize the non-power outage transmission operation.

[0051] The technical solution of the embodiment of the present invention obtains the message interaction information between the bus interval and the line interval of the smart substation; the line interval includes: the basic line interval and the reconstruction and expansion line interval; the standardized virtual terminal of each intelligent electronic device and the virtual circuit formed between each intelligent electronic device and the virtual terminal are determined according to the message interaction information; the virtual terminal includes: the publishing end virtual terminal and / or the subscribing end virtual terminal; for each intelligent electronic device, the message communication parameters of the intelligent electronic device are configured according to the publishing end virtual terminal associated with the virtual circuit; a pre-configuration file is generated according to the information of each virtual terminal of the intelligent electronic device and each message communication parameter; the pre-configuration file is used to configure the communication parameters of the bus interval and the basic line interval in the infrastructure construction stage of the smart substation, and configure the communication parameters of the reconstruction and expansion line interval in the reconstruction and expansion stage of the smart substation, and based on the pre-configuration method, the bus interval and the basic line interval do not need to be powered off and transmitted. The configuration of the reconstruction and expansion line interval is completed, thereby reducing the workload of on-site operations for reconstruction and expansion, reducing operational risks, reducing power outage time, and improving the stability of the smart substation.

If the communication parameters such as APPID, MAC address, goID, smvID in the message and the virtual terminal information in the message are consistent, it is determined that the pre-configuration file is correct.

[0134] In a specific example, taking the expansion of the 6th line interval of the 110kV single busbar connection as an example, the specific implementation method of the non-stop transmission operation is: in the basic construction stage, the busbar protection defines the publishing end virtual terminal from the publishing end to all branches according to the standardized virtual terminal, including the branch 6 expanded later. At the same time, the virtual terminals subscribed from all branches are defined, including the branch 6 expanded later. Therefore, during the reconstruction and expansion stage of branch 6, there is no need to modify the configuration file for the busbar protection device, and all the publishing end and subscription end virtual terminals have been defined. For the branch 6 interval, according to the standardized virtual terminals and pre-configured files, combined with the manufacturer and model of the on-site secondary equipment and other information, the configuration update of the branch 6 interval is completed. When the secondary equipment of the branch 6 interval is connected to the substation network, the interval receiving soft pressure plate of branch 6 in the busbar interval is put into use to complete the expansion operation of the branch 6 interval.
