The Research Of Generation-transformer Group Fault Recorder's Information Analysis And Diagnosis System

Generator-transformer is most important device in modern power system, more kind of fault, different fault causes, that make it difficulty for analysis and judgments of fault, which is very important for the safety and running stably of unit, however some fault recorder in use exist some shortcomings in performance, such as impertinency configure in hardware, small system capacity, The speed of the serial port is very slow, the function of high frequency recorder have limited, data analyses in line the clock is no proficiency ,the computer is often out of whack, However some recorder of unit can only matriculate the waveform such as the analysis and calculate of electric parameter that the worker want to know , find the cause of fault correctly, analysis and appraise the action of protection and automechanism. They can do nothing, The paper bring out a new-type fault recorder scheme based on Ethernet communication and DSP, this scheme adopts many advanced technologies and development flat roofs, such as GPS, DSP. Object Oriented Programming, it has been using in practicality and bring out better effect.
