- Abstract
In the modern power system, relay protection device is an important tool to ensure the safe operation of the power system and monitor the quality of electricity. Traditional microcomputer relay protection device has a low computing speed, and its protection principle is also imperfect. A device of relay protection based on dual cores TMS320F2808 + N78E366A is developed, the hardware of each module part is designed. The filtering performance of the full wave Fourier algorithm is compared with the differential full wave Fourier algorithm. Then the performance of the above two algorithms is verified through simulation, meanwhile the system algorithm and the sampling points are selected. Finally, the main program diagrams of system software have also been given. The device is fast, reliable, easy to maintain, strong anti-interference, cute size, and can been easily configured into various types protection and control according to users' needs.
