| With the development of society and the improvement of the science technology, strong power system and weak power system have been permeating with each other. However, strong power system can cause electromagnetic interference and affect weak power system’s normal work,With the rapid development of China’s national economy, the demand of electric power from all walks of life has rapid increase. Besides, due to our country’s energy distribution characteristics, the technology of UHV transmission has great development, and the transmission voltage grade is continuously improving. Meanwhile, with the characteristics of fast speed, large transport amount, better economy, light environment pollution and comfortable, rapid transit railway has got the favor of people and rapid development.In this paper, the influence on short-wave radio direction finding stations and short-wave radio receiving stations from surrounding rapid transit railway and UHV transmission line has been studied. First, this paper analysis the characteristics of rapid transit railway and UHV transmission line’s interference source. And discuss the characteristics of short-wave propagation. Afterwards, from the point of view of the theory, this text discussed the features of radio interference of rapid transit railway. And analysis the interference on short-wave radio direction finding stations and short-wave radio receiving stations from radio interference of rapid transit railway with the speed of 300km/h. In the end, this paper analysis the passive interference on short-wave antenna from UHV transmission line by means of entity modeling and simulation technologies. In addition, this text mainly discuss the passive interference on short-wave’s direction figure in case of the protecting distance and line route of UHV transmission line. |
