3、ionThe electrical power system rapid development to the relay protection proposed unceasingly t he new request, the electronic technology, computer technology and the communication rapid development unceasingly has poured into the new vigor for the relay protection technology de velopment, therefore
4、, the relay protection technology is advantageous, has completed the deve lopment 4 historical stage in more than 40 years time.After the founding of the nation, our country relay protection discipline, the relay protection de sign, the relay manufacture industry and the relay protection technical t
5、eam grows out of noth ing, has passed through the path in about 10 years which advanced countries half century pa sses through. The 50s, our country engineers and technicians creatively absorption, the diges tion, have grasped the overseas advanced relay protection equipment performance and the m ov

The acheng relay factory introd uction has digested at
7、that time the overseas advanced relay manufacture technology, has est ablished our country relay manufacturing industry. Thus our country has completed the relay p rotection research, the design, the manufacture, the movement and the teaching complete sys tern in the 60s. This is a time which the me
8、chanical and electrical relay protection prospers, was our country relay protection technology development has laid the solid foundation.From the end of the 50s, the transistor relay protection was starting to study. In the 60s to t he 80s in are the times which the transistor relay protection vigor

Tianjin University and the Nanjing electric power automation plant cooperation research 500kv transistor direction high frequency protection the transistor high frequency block system which develops with the Nanjing electric power automation research institute is away
10、 from th e protection, moves on the Gezhou Dam 500 kv line , finished the 500kv line protection to d epend upon completely from the overseas import time.From the 70s, started based on the integration operational amplifier integrated circuit protectio n to study. Has formed the complete series to at
11、the end of 80s integrated circuit protection, substitutes for the transistor protection gradually. The development, the production, the applica tion the integrated circuit protects which to the beginning of the 90s still were in the dominan t position, this was the integrated circuit protection time

Huazhong University of Science and Technology, southeast the university, the North C hina electric power institute, the Xian Jiaotong University, the Tianjin University, Shanghai Jiao tong University, the Chongqing University and the Nanjing electric po
15、wer automation research institute one after another has all developed the different principle, the different pattern microc omputer protective device. In 1984 the original North China electric power institute developed the transmission line microcomputer protective device first through the appraisal
16、, and in the system the find application, had opened in our country relay protection history the new page, pr otected the promotion for the microcomputer to pave the way. In the host equipment protectio n aspect, the generator which southeast the university and Huazhong University of Science a nd Te
