Automatic self-description interface control document (ICD) encoder

Abstract

The invention relates to an automatic self-description interface control document (ICD) encoder, comprising a single chip microcomputer, characterized in that the encoder consists of a single chip microcomputer, a secure digital(SD) card, a clock oscillation circuit and a power filter circuit, the single chip microcomputer being connected with the SD card, writing date into the SD card and also being connected with the serial port of a distribution automation terminal communication unit, the SD card being connected with the serial peripheral interface(SPI) of the distribution automation terminal communication unit, the power filter circuit being connected between the power source and the SD card, and the clock circuit being connected with the single chip microcomputer. Data as remote signaling data, remote measurement data and remote control data, sampled by the distribution automation terminal is automatically generated to be self-description ICD documents meeting the International Electrotechnical Commission (IEC) 61850 standard, which avoids the defects of low work efficiency, high malfunction probability and long testing period, resulted from the allocation of manual production remote information point table and manual test point table. The encoder is simple in the structure, convenient in installation and use, and reliable in performance.

Description

technical field [0001] The invention relates to a power distribution automation terminal equipment for a power grid, in particular to a self-describing ICD file automatic encoder. Background technique [0002] The modification of telecontrol information point tables and communication parameters of traditional power distribution automation terminal equipment mainly depends on manual configuration. After the information point table is configured and the local test is correct, the master station and the factory station will conduct a point-by-point test. The probability of error is high and the test cycle is long. Generally, it takes more than 6 hours. In the power distribution automation system, the power distribution terminal The huge number makes it very difficult to maintain and debug the distribution automation system. In addition, due to size limitations, most of the current distribution automation terminals use DSP (digital signal processors) and microcomputers as core ...

[0002] The modification of telecontrol information point tables and communication parameters of traditional power distribution automation terminal equipment mainly depends on manual configuration. After the information point table is configured and the local test is correct, the master station and the factory station will conduct a point-by-point test. The probability of error is high and the test cycle is long. Generally, it takes more than 6 hours. In the power distribution automation system, the power distribution terminal The large number makes it very difficult to maintain and debug the distribution automation system

In addition, due to size limitations, most of the current distribution automation terminals use DSP (digital signal processors) and microcomputers as core processors to process remote signaling signal acquisition, telemetry and AC sampling, remote control output, local and remote communications and other tasks. , the remaining business processing capacity is very limited, it is difficult to complete the self-describing function of the device that meets the IEC 61850 standard, and adding this function to the original software code requires a lot of re-testing of the original function, and the workload is very heavy
