Research of a New Line Protection Measurement and Controlling Device Based on DSP

摘要：

This paper presents the design of a new line protection measurement and controlling device,including its hardware system, software function and algorithms. The core component of the device is TMS320LF2407A DSP, which is rapid and strong. Through advanced high-speed DSP (Digital Signal Processing) technology, serial A/D, serial EEPROM, CAN bus, surface craft and backward structure, the device integrates protection with far action function. It can fulfill protection, fault record, four functions(YX,YK,YC,YT), communication, electrical power calculating and collecting, and so on. The design of the devices software system is modular. Through combining hardware analogue record wave and software digital record wave, Fourier algorithm and software compensation power angle algorithm 32 points per cycle, it guarantees the devices reliability, advancement and measurement precision.
