卫星授时信号干扰影响现状分析

Analysis on the Status Quo of Satellite Timing Signal Interference

电网运行过程中,对时间同步的依赖日益显著,时间同步系统已成为电力自动化系统运行的基础支持系统。但由于卫星授时信号的公开性,使得电力授时采用的授时信号易受虚假卫星信号欺骗,产生错误的定位和授时信息。对此,通过阐述国内外卫星授时及定位抗干扰研究水平的现状和发展趋势,分析抗干扰实现方式的理论依据,从而提出了卫星授时信号抗欺骗干扰的可行性和必要性。

In the process of power grid operation,the dependence on time synchronization becomes more and more obvious,and time synchronization system has become the basic support system of power automation system operation.However,due to the openness of the satellite time service signal,the power time service signal is easily deceived by the false satellite signal,resulting in the wrong positioning and time service information.In this regard,this paper describes the current situation and development trend of anti-jamming research level of satellite time service and positioning at home and abroad,analyzes the theoretical basis of anti-jamming implementation mode,and puts forward the feasibility and necessity of anti deception jamming of satellite time service signal.
