As the generator is a more complex equipment in power plant, the change of parameters of generator and transformer must be truly reflected in case of fault or abnormality. It is necessary to record not only the stator voltage and current of generator, but also the voltage and current of generator rotor, that is, the change of DC parameters of excitation system.

The fault recording device of generator transformer group is composed of two boxes. Each cabinet is independently completed by data unit to collect 96 analog signals and 192 switch signals. The boxes are connected by communication lines. Analog signal and switch signal are transmitted from the backplane, not through the signal line, with strong anti-interference ability. The management unit adopts industrial control module with high performance, low power consumption and no fan to complete the data acquisition, processing and storage of multi-channel data acquisition unit with good reliability.

The fault recorder realizes all functions of the fault recorder on the embedded system, and adopts the operating system: Linux General operating system sys / BIOS real-time operating system, which ensures the reliability and real-time performance of the system for a long time, and also avoids the uncontrollable risk of other manufacturers using Windows system. The data acquisition unit of the system has high acquisition frequency, strong calculation function and high calculation accuracy.

The generator transformer fault recorder can start automatically in case of fault. The components and materials specially used for dynamic recording device of power system and the most advanced embedded platform are selected, which not only realizes all functions of fault recorder, but also its advanced application functions, and effectively supports intelligent application in IEC61850 communication The demand of.
