【Abstract】 In this paper the authors have discussed a way how to use MC6809 to compose the PLC linked current phase comparison protection, Some problems existed in the traditional current phase comparison relays have been solved. Some new ideas and ways for improving the reliability and speed of the relay are presented. Dynamic simulation test shows that the new protective relay based on MC6809 is more satisfactory than the traditional one.更多还原
