Embedded transformer station information integrated server

Abstract

The invention relates to an embedded substation information integration server, which is composed of a core processing module (1), an ethernet communication interface module (2), a CAN bus communication interface module (3), a serial communication interface module (4) and a switching value input-output module (5), and wherein, the core processing module (1) is composed of a processor AT91RM9200 (11), a synchronous dynamic random access memory (12), a parallel flash memory (13), a NAND flash memory (14), an electrically erasable programmable read-only memory AT24C512 (15), a real-time clock (16), a watchdog timer (17), a complex programmable logic device XC95144 (18) and peripheral auxiliary circuits, which jointly construct a basic embedded system. The invention applies uniform network and specification systems to develop the embedded substation information integration server which has the advantages of high performance, high openness, high reliability and low cost and realizes the interconnection and interoperation among the devices of different manufacturers, thus providing a data service platform for the integration, sharing and comprehensive processing of information.

Description

technical field [0001] The invention relates to a general hardware platform and a data service platform for realizing information integration of substations, and belongs to the technical field of substation automation in electric power systems. Background technique [0002] Various smart devices from different manufacturers in the substation, such as protection devices, smart watt-hour meters, centralized watt-hour collectors, DC screens, arc suppression coil control devices, small current grounding line selection devices, insulation detection devices, independent VQC devices, Fault recorders, etc. must be connected to monitoring, telecontrol and other information processing master stations. Due to the different production years and technical levels of these devices, each manufacturer implements its own communication mode, which makes it difficult to communicate and connect between devices from different manufacturers. This situation is more common especially in low-voltage ...

AI Technical Summary

Problems solved by technology

The communication network and data transmission protocols of the substation automation system are not uniform, making it difficult for products from various manufacturers to interconnect and interoperate, which brings a lot of protocol conversion and debugging workload, brings inconvenience to operation and maintenance, and leaves a lot of trouble for the reliable operation of the system.
