Applications of DSPARM for microprocessor protection device in distance protection

摘要

By studying the development of microprocessor protection and features of the protection devices, the requirement of the device under the multi-mission of monitoring, protecting, controlling and communicating is discussed in this paper, and a microprocessor protection device of dual CPU structure with ARM & DSP is designed. DSP TMS320F2812 and ARM S3C2410 are used in this design. The print circuit boards of this device are finished and fast Fourier transform is chosen. According to the distance protection scheme in 110 kV transmission based on MATLAB, the tests of the device are done. The results show that the design of DSP & ARM in this paper is feasible in microprocessor protection, and it has a simple and reliable circuit structure and is expandable on software and hardware.
