摘　　要：本文论述了用MC6809微机实现的相差高频保护装置的构成方法。提出了一些新的构思与设想。解决了目前模拟型的相差高频保护存在的一些问题。经实验室试验与动模试验证明性能良好。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.
