Embodiment 1

[0036] figure 1 This is a schematic diagram of the network structure on which the method for smart substation service configuration according to this embodiment is based. The method for smart substation service configuration described in this embodiment may include the following steps:

[0037] 1) After the user port of the ONU built-in optical network unit of the power protection device receives the service message, it sends the service message to the FPGA unit of the ONU;

[0038] 2) After the FPGA unit receives the message, it identifies the message type according to the Ethertype field in the message, distinguishes whether it is SV, GOOSE or MMS, and then queries the specific register entry according to (port+type+appid). If the message is not hit (it is considered to be an unknown message), the FPGA unit adds a 4-byte custom field after the mac field of the message in a fixed format, plus port information and priority information , and then forwarded to the CPU port of ...

Embodiment 2

[0042] Based on the same inventive concept, the present invention also provides a device for smart substation service configuration, such as image 3 As shown, it includes: an optical network unit ONU, the ONU includes a user port 1, an FPGA unit 2, a CPU port 3 and an execution module 4, wherein,

[0043] The user port 1 of the optical network unit ONU is used to send the service message to the FPGA unit of the ONU after receiving the service message;

[0044]The FPGA unit 2 is used to identify the message type of the message, and when the message type does not exist in the pre-register table entry, a 4-byte custom field is added after the mac field of the message, The port information and priority information of the packet are added in the 4-byte custom field, and sent to the CPU port 3 of the ONU. The message types include SV, GOOSE, and MMS. The format of the self-defined field adopts the vlantag format. In the vlan part of the low 12 bits, the high 7 bits indicate wheth...

Embodiment 3

[0048] Step 1), discovery of unknown business

[0049] After the power protection device is connected to the network, the service packets enter the power protection device through the user port of the built-in onu of the power protection device. After the packet is entered, it is first sent to the FFPGA unit of the ONU. The Ethertype field in the middle identifies the type of the message, distinguishes whether it is SV, GOOSE or MMS, and then queries the specific register entry according to (port+type+appid). If the entry is hit, it will be forwarded normally. is an unknown message.

[0050] Step 2), forwarding of unknown packets

[0051] If the table lookup does not hit the entry, the FPGA adds a 4-byte custom field after the mac field of the message in a fixed format, plus port and priority information, and forwards it to the CPU port of the ONU.

[0052] Step 3), message parsing

[0053] After the internal program of the ONU mentions the message from the internal CPU por...

Abstract

The invention discloses a service configuration method and device for an intelligent transformer station. A user port of a built-in ONU (Optical Network Unit) of a power protector receives a service message, and then sends the service massage to an FPGA unit of the ONU; the FPGA unit identifies a type of the message, adds the message to a customized field according to a preset format when a preset dwell vessel item does not include the message type, and sends the message to a CPU port of the ONU; and an internal program of the ONU receives the message from the CPU port, determines whether the message is a message discovered by a new service according to the customized field, and if YES, determines information of the new service according to the message, and the information of the new service is used to configure the new service. According to the method and device, the problems that configuration during onsite construction, reconstruction and upgrade of the transformer station is tedious and a system is not friendly to maintenance staff of the transformer station are solved.

Description

technical field [0001] The invention relates to a method and a device for smart substation service configuration, belonging to the technical field of smart grid. Background technique [0002] The current protection network of smart substations adopts a point-to-point transmission method. Each SV and each GOOSE are directly connected by an optical fiber, and each service does not interfere with each other. Although it is said to be a network, it is actually just a collection of multiple lines. Such a network has good reliability, but has a large waste of resources. [0003] The new generation of intelligent substations proposes the integration of three networks, the station control layer, the interval layer, and the process layer. The multi-layer services of each device are connected to the network through one interface, which saves a lot of optical fibers and makes wiring management easier. In the triple play network, in order to avoid the mutual influence between differen...
