Application of DSP on Power Transformer Protection Device
Abstract：On the basis of researching power transformer longitudinal differential protection principle and magnetizing surge current produce condition,the dual-DSP（Digital Signal Processor） structure transformer protection scheme is proposed by improved Fourier algorithm.Using DSP control technology,capability of parameters detection for power transformer protection device and real-time data processing has been strengthened effectively.The research results showed that this design was kind of feasible and practicable method to optimize the performance of transformer protection device.
