Embodiment Construction

[0023] specific implementation plan

[0024] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0025] Such as figure 1 As shown, the "simplified point-to-point + two-network integration" networking scheme designed in this embodiment is adopted.

[0026] "Simplified point-to-point + two-network-in-one" networking scheme, the interval protection, measurement and control and metering functions are directly connected to the process layer merging unit and intelligent terminal in a point-to-point way with optical fiber, so as to ensure the "function autonomy" of each interval and obtain maximum operational reliability .

[0027] No dedicated process layer network, station c...

Abstract

The invention discloses a protection measurement and control device with SV and GOOSE transparent transmission functions, which mainly includes: a PLC processing module and a communication processing module. The PLC processing module realizes logical operation and is connected with the communication processing module to realize data interaction; the communication processing module realizes communication Data aggregation and transmission, real-time data interaction between two modules; PLC processing module includes: PLC controller, PCI communication interface, wherein: PLC controller is connected with PCI communication interface, and exchanges information with the communication processing module via PCI bus, the communication processing module includes : communication control sub-module, process layer communication interface, station control layer communication interface and PCI communication interface, the PCI communication interface faces the PCI bus, and realizes information interaction between the communication processing module and the PLC processing module. The protection measurement and control device can simplify the networking scheme, reduce investment, facilitate construction, and realize the transparent transmission function of SV, GOOSE, and IEC1588 messages.

Description

[0001] Technical field: [0002] The invention relates to the technical field of electric power relay protection, in particular to a protection, measurement and control device that integrates protection, measurement and control functions and supports SV, GOOSE, IEEE1588 and MMS message co-cable transmission technology and transparent transmission technology. [0003] Background technique: [0004] Smart substation is an important part of my country's smart grid national strategy, and it is also the latest requirement for the technical form of substations in the smart grid environment.
