A fault line selection system in distribution network based on DSP and ARM processor is designed. The TMS320F28335 chip is used to design the data acquisition unit of the DSP. The S3 C2440 chip is used to design the fault diagnosis machine of the ARM and is set as the core of algo-rithm processing. And the CAN bus is used to connect the two ones. The fault measurements of the fifth harmonic current,the wavelet energy and the active power before and after the fault of each dis-tribution line are fused to diagnose fault using BP neural network. The application of this system in Dexing Copper Mine of Jiangxi Copper Group proves that it has high fault line selection accuracy and operation reliability.
