Network processor based on standard IEC61850

Abstract

The invention provides a network processor based on the standard IEC61850. The network processor comprises a processor module, a storage module, a storage controller module, a clock management module, an internal control module, an interface controller module and an external interface module; the storage module, the storage controller module, the clock management module, the internal control module, the interface controller module and the external interface module are all in both-way connection with the processor module through AMBA buses. The network processor supports the IEC61850 protocol function, achieves high instantaneity and low power consumption, and is applied to an intelligent transformer substation and a power distribution automation communication system.

Description

technical field [0001] The invention belongs to the technical field of information communication integration, and in particular relates to a network processor based on the IEC61850 standard. Background technique [0002] Smart grid is a crossover technology that integrates grid technology and information electronics technology. It is based on an integrated, high-speed, two-way communication network, covering basic measurement, digital substations, distribution automation, and microgrids. Traditional substation communication protocols mainly include: CDT, SC1801, DNP3.0, N4F, 101, 103, 104, etc. The interfaces and functions provided by the power equipment supporting these protocol standards are different, and the "island" problem between equipment is serious , Information sharing is difficult, which is not conducive to the stability and maintenance of the power system. In order to facilitate the management and interconnection of various IED devices in smart substations, the ...

Problems solved by technology

There are also many problems in the communication board method: the hardware circuit connection is complicated, the crosstalk is large, and the system stability is affected; the power dissipation of the communication board is large, and the uneven heat dissipation causes the system to restart; the structure is complex, the development is difficult, the cycle is long, and the operation and maintenance are difficult. ;Many materials are used, and the input cost is high; the volume is large, which is not conducive to the localization of secondary equipment; in addition, the IEC61850 protocol is complicated, and it is easy to make mistakes when decoding by software

All of the above problems may pose a potential threat to the security and stability of the power grid.
