2、system security and economic operation, power plants and users are linked to the intermediate link, plays a transformation and distribution of electric energy effect.This paper reviewed the power system protection technology in China after the process of development, this paper Outlines the microcom

3、puter relay protection technology achievements, this paper puts forward the future relay protection technology development trend is：Computerized, and the electric network, protection, control, according to the results of the survey and data communications integration and artificial Intelligent. Key

4、word：relay protection present situation development The future development of the relay protection substation1. relay protection development present situation The electrical power system rapid development to the relay protection proposed unceasingly the new request, the electronic technology, comput

5、er technology and the 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

6、 of the nation, our 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

7、engineers and technicians 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

8、 grew the instruction function to the national relay protection technical teams establishment. The 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 rel

9、ay protection 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,

10、 the transistor 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

11、 protection 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

12、70s, started 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 c

13、ircuit protects 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

14、 frequency protected 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 strip 220kv and on the 500kv line. Our country namely started t

15、he computer relay protection research from the end of the 70s , the institutions of higher learning and the scientific research courtyard institute forerunners function.
