Generator transformer unit faults recorder analysis device

Abstract

A generator transformer unit faults recorder analysis device belonging to the field of power system faults recorder devices consists of a storage station and a monitoring station and adopts a master-slave hierarchical network structure, wherein the storage station adopts a server computer and the monitoring station consists of a signal transducer unit, an intelligent collecting-analyzing unit, a GPS unit, an industrial computer unit and a power-supply unit, wherein the signal transducer unit is connected with the intelligent collecting-analyzing unit; the intelligent collecting-analyzing unit comprises a data collecting card, an FPGA module and a real-time embedded controller and is respectively connected with the industrial computer unit and the server computer of the storage station; the GPS unit is connected with the real-time embedded controller of the intelligent collecting-analyzing unit; and the power-supply unit is respectively connected with the intelligent collecting-analyzing unit and the industrial computer unit. Established on the basis of the components, a related system reinforces reliability, enhances real-time property and lowers complexity and cost thereof.

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
