4、he communication rapid development unceasingly has poured into the new vigor for the relay protection technology development, therefore, the relay protection technology is advantageous, has completed the development 4 historical stage in more than 40 years time. After the founding of the nation, our
5、 country relay protection discipline, the relay protection design, the relay manufacture industry and the relay protection technical team grows out of nothing, has passed through the path in about 10 years which advanced countries half century passes through. The 50s, our country engineers and techn
6、icians creatively absorption, the digestion, have grasped the overseas advanced relay protection equipment performance and the movement technology , completed to have the deep relay protection theory attainments and the rich movement experience relay protection technical team, and grew the instructi
7、on function to the national relay protection technical teams establishment. The acheng relay factory introduction has digested at that time the overseas advanced relay manufacture technology, has established our country relay manufacturing industry. Thus our country has completed the relay protectio
8、n research, the design, the manufacture, the movement and the teaching complete system in the 60s. This is a time which the mechanical and electrical relay protection prospers, was our country relay protection technology development has laid the solid foundation. From the end of the 50s, the transis
9、tor relay protection was starting to study. In the 60s to the 80s in are the times which the transistor relay protection vigorous development and widely uses. Tianjin University and the Nanjing electric power automation plant cooperation research 500kv transistor direction high frequency protection
10、the transistor high frequency block system which develops with the Nanjing electric power automation research institute is away from the protection, moves on the Gezhou Dam 500 kv line , finished the 500kv line protection to depend upon completely from the overseas import time. From the 70s, started
11、 based on the integration operational amplifier integrated circuit protection to study. Has formed the complete series to at the end of 80s integrated circuit protection,substitutes for the transistor protection gradually. The development, the production, the application the integrated circuit prote
12、cts which to the beginning of the 90s still were in the dominant position, this was the integrated circuit protection time. The integrated electricity road work frequency conversion quantity direction develops which in this aspect Nanjing electric power automation research institute high frequency p
13、rotected the vital role , the Tianjin University and the Nanjing electric power automation plant cooperation development integrated circuit phase voltage compensated the type direction high frequency protection also moves in multi- strip 220kv and on the 500kv line. Our country namely started the co
14、mputer relay protection research from the end of the 70s , the institutions of higher learning and the scientific research courtyard institute forerunners function. Huazhong University of Science and Technology, southeast the university, the North China electric power institute, the Xian Jiaotong Un
15、iversity, the Tianjin University, Shanghai Jiaotong University, the Chongqing University and the Nanjing electric power automation research institute one after another has all developed the different principle, the different pattern microcomputer protective device. In 1984 the original North China e
16、lectric power institute developed the transmission line microcomputer protective device first through the appraisal, and in the system the find application, had opened in our country relay protection history the new page, protected the promotion for the microcomputer to pave the way. In the host equ
17、ipment protection aspect, the generator which southeast the university and Huazhong University of Science and Technology develops loses magnetism protection, the generator protection and the generator?Bank of transformers protection also one after another in 1989, in 1994 through appraisal, investme
18、nt movement. The Nanjing electric power automation research institute develops microcomputer line protective device also in 1991 through appraisal. The Tianjin University and the Nanjing electric power automation plant cooperation development microcomputer phase voltage compensated the type directio
19、n high frequency protection, the Xian Jiaotong University and the Xu Chang relay factory cooperation development positive sequence breakdown component direction high frequency protection also one after another in 1993, in 1996 through the appraisal. Heres, the differentprinciple, the different type
20、microcomputer line and the host equipment protect unique, provided one batch of new generation of performance for the electrical power system fine, the function has been complete, the work reliable relay protection installment. Along with the microcomputer protective device research, in microcompute
21、r aspect and so on protection software, algorithm has also yielded the very many theories result. May say started our country relay protection technology from the 90s to enter the time which the microcomputer protected. 2 relay protections future development The relay protection technology future the tendency will be to computerizes, networked, the intellectualization, will protect, the control, the survey and the data communication integration development. 2.1 computerizes
