Description

technical field [0001] The invention belongs to the field of fault recording devices for power systems, in particular to a fault recording and analysis device for a generator transformer set (hereinafter referred to as a generator-transformer set). Background technique [0002] As an important source equipment in the power system, the generator set will have a direct impact on the safe operation of the power system and the quality of electric energy if the faults and abnormalities occur. With the sustained and rapid development of the social economy, the demand for electric energy has soared, and a large number of new, expanded and renovated power plants have emerged as the times require, and the scale of the electric power industry is expanding day by day. As an important source equipment in the power system, the generator set is expensive and is one of the most invested equipment. Because large-capacity units have the characteristics of relatively low cost, high operating...

AI Technical Summary

Problems solved by technology

It can greatly improve the monitoring and operation level of the power network, improve the accuracy and reliability of fault recording, improve the work efficiency of operators, and improve the safe operation level of generator sets. It has broad application and development prospects, but due to the limitations of system structure and performance The reason is that when the industrial computer of the system fails, the system will not be able to operate normally, and there are deficiencies in real-time performance and anti-interference

[0005] At present, the assembly rate of wave recording devices for large and medium-sized units is not high. Most of the fault recording devices that have been assembled are products in the early 1990s. The outdated technology and the lack of understanding of the research and development personnel on the generator set have led to the current domestically produced The operation of the generator-transformer fault recording device is not satisfactory: low technical indicators, easy data loss, poor configurability, incomplete information, substandard data format, imperfect monitoring and analysis tools, poor network capabilities, weak communication capabilities, crashes , false start, refusal to start and other serious problems
