Abstract:The measurement and control equipment for relay protection was based on DSP. The electric quantity value and subharmonic were measured and analyzed by FFT to realize the real time detection on electricity net. The double CPU structure was adopted by equipment; the TMSVC was used to calculate; the MSP430F149 was used to control the communication; the XC95144X chip was used to realize the logic control; the MAX125 chip was used to realize the conversion between model and figure; the HPI interface was adopted to achieve the high-speed data transmission between DSP and singlechip. The algorithms compiling of high subharmonic restrain and microcomputer protection is the core of DSP software. The algorithm also includes data processing algorithm, sampling spots, choosing the sampling start time and so on.
Keywords:Measurement and control equipment for relay protection  TMSVC5410  MSP430F149  XC95144X  HPI  FFT (Fast Fourier Transform Algorithm)
