Problems solved by technology

And from the actual situation, in the equipment communication control module, due to the different understanding of the 103 protocol, some non-standard situations have also occurred, resulting in the 103 of different manufacturers and different products (even the same manufacturer) are not fully compatible. of
Therefore, it is difficult to realize a general communication gateway by conventional methods
If a dedicated gateway is used, there are many types of gateways, and the workload of developing, maintaining, and verifying gateways is huge

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] 1. Hardware design

[0033] Currently, the vast majority (over 95%) of 103 legacy IEDs at the bay level are implemented based on RS-485 serial communication ports, while IEC 61850 is based on Ethernet interfaces. Therefore, the gateway hardware is required to have RS-485 / Ethernet conversion function, and have a certain program storage area and data storage area. On this basis, configuration files can be written and downloaded, and the hardware system can run stably and reliably. Accompanying drawing 1 is the schematic diagram of the hardware principle that the present invention selects.

[0034] The CPU used in this universal gateway is Samsung's 32 processor s3c4510B. This chip is specially developed for embedded Ethernet applications. The core is ARM7TDMI, and the working frequency is 50MHz. The chip integrates 2 UARTs and 1 Ethernet controller. , ...

Abstract

This invention discloses a gateway design method 0f conversing the 103 protocol for the realization of IEC 61850 generic. Because of IEC 61850 is the unified standard network of communication substation, substation layout of the heavily adopted IEC 60870-5-103 agreement on the remaining products is an obstacle for the implementation of IEC 61850,and the Model of legacy is numerous, if using special gateway, the types of gateway request many models, development, maintenance, validation which is a tremendous workload.. To address the problem, this invention uses a new agreement mapping method - XML Schema meta-data mapping method to establish a complete 103agreement and XML Schema model of IEC 61850, then describe the mapping rules between two models using XML Schema. Its hardware is based on embedded system technology, which is low cost, small size. Engineering staff only adjust configuration files; can realize conversion between IEC 60870-5-103 protocol agreement and the IEC 61850, instead of changing of Gateway hardware and software system and changes in code.

Description

technical field [0001] The invention belongs to the technical field of power system substation communication dispatching, and in particular relates to a general gateway design method for realizing the IEC61850 standard. Background technique [0002] The communication protocol of a large number of products (hundreds of thousands) in the existing substation bay layer adopts the IEC60870-5-103 (hereinafter referred to as 103) protocol, and the IEC 61850 standard has been widely accepted as a new unified substation network communication standard. It is of great significance to transform a large number of products left over from these spacers that do not meet the IEC 61850 standard to meet the IEC 61850 standard. [0003] However, since 103 is a point-oriented protocol. The so-called point-oriented refers to relying on various data address "point" values ​​to distinguish different information, such as a certain switch state, a certain line's voltage, current or power and other m...
