Intelligent substation operation information processing system and processing method

Abstract

The invention discloses a system and method for processing operation information of a substation. The system comprises an FPGA chip, a first DSP chip, a first RAM and a second RAM, wherein an internal memory is arranged inside the FPGA chip, and the FPGA chip is used for capturing network messages and storing the network messages in the internal memory of the FPGA chip; an internal memory is arranged inside the first DSP chip, and the first DSP chip is used for data fractionation, wave recording calculation and fault location, and starting data are generated and stored in the internal memory of the first DSP chip; the first RAM is respectively and electrically connected with the FPGA chip and the first DSP chip and used for reading data from the internal memory of the FPGA chip under the control of the FPGA chip so that the data can be processed by the first DSP chip; the second RAM is respectively and electrically connected with the FPGA chip and the first DSP chip and used for caching the starting data in the internal memory of the first DSP chip so that the starting data can be read by the internal memory of the FPGA chip. The processing efficiency of the captured network messages is high, timely transmission of fault information is facilitated, and timely and effective analyzing and positioning of operation faults of the substation are facilitated.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a processing system and method for operating information of an intelligent substation. Background technique [0002] In the joint commissioning and operation of the traditional substation automation system, situations such as background monitoring, unattended centralized control station and dispatching automation master station system remote signaling or incomplete events, unsuccessful remote control, and measurement jumps often occur. When these situations occur in systems such as automatic reactive power control (AVQC) and automatic generation control (AGC) of remote or local automatic closed-loop control, the seriousness is even more prominent. Practice has shown that most of these situations are caused by communication failures. However, due to the lack of effective technical means, it is impossible to reproduce the communication process when the problem occurred, so ...

AI Technical Summary

Problems solved by technology

At this time, traditional troubleshooting methods cannot meet the requirements, and errors in the communication process are difficult to reproduce

[0004] The existing technology is inefficient in processing captured network messages, resulting in failure to transmit fault information in time, which easily affects the timely and effective analysis and positioning of substation operation faults
