摘　　要：在我国社会不断发展的当下,人们对于文化生活的追求日渐提升。卫星广播电视地球站作为转播电视广播信号的工作单位,承担着为广大群众文化生活服务的任务。在卫星广播电视地球站当中,电力系统是保障广播电视信号接收、转播的重要基础设施。为了切实有效地服务社会,应积极利用可编程控制器,以其为核心构建出控制系统和机组系统,通过完善局部电源供电网络,协调多个电路的分配以及切换问题,实现一台机组满足多个电路共同反应与同期操作的目的。本文将以某卫星广播电视地球站供电线路、供电网为例,合理地对多路电源与应急发电机组自动切换控制系统开展设计,得出不同功能系统的设计方案,有效推动广播电视转播事业发展,为人们的工作生活带来便利。With the continuous development of our society,people’s pursuit of cultural life is increasing.Satellite radio and television earth station,as the work unit of TV broadcast signal transmission,undertakes the cultural life service task of the masses.In the satellite radio and television earth station,power system is an important technical basis to ensure the reception and transmission of radio and television signals.In order to effectively serve the society,we should actively use PLC as the core to build the control system and unit system to meet the needs of social development.Through the perfect local power supply network,coordinate the distribution and switching of multiple circuits,a unit can meet the purpose of multiple circuits common reaction and simultaneous operation.This paper will take a certain earth station as a template,take the power supply circuit and power grid of the satellite radio and television earth station as an example,design the automatic switching control system of multi-channel power supply and emergency generator set effi ciently and reasonably,get the design scheme of different functional systems,effectively promote the development of broadcasting and television,and bring convenience to people’s work and life.
