Research On Optical Fiber Communication System For Hengjiang Substation Of Zhaoqing

China's electricity demand development has been accelerating in recent years.In order to ensure the stable operation of power facilities such as power plants,substations and transmission lines,the role of power communication is very important.Zhaoqing is located in the Midwest of Guangdong Province,most of the area is in the hills and mountains,and most of thunderstorms here every year.For substations in remote areas,the transmission line distance is longer.Fiber optic cable on the outdoor power lines are often vulnerable to lightning strikes,to keep power network operating in safe and stable condition,the telecommunication network must be uninterrupted and low delay.Zhaoqing 110 kV Hengjiang Substation is important for communication network.He will assume the important task of industrial development in Gaoyao Huodao of Zhaoqing.High reliability requirements for power communication systems.Power system communication is aimed at serving the power grid,so the reliability requirements of the communication network are also high.Based on current research results,the research and discussion on the lightning protection design,equipment selection optimization,networking mode,function realization and application effect of Hengjiang Station communication system are discussed.Thesis is mainly reflected in the following aspects:(1)According to the networking of Zhaoqing area power grid operation,the communication scale of Hengjiang station is introduced.The networking mode of the access system of Hengjiang station is analyzed and compared,and the optimal networking strategy is selected.(2)According to the geographical and climatic characteristics,the optical cable selection,optical cable lightning protection design,fitting configuration,and split welding of Hengjiang station are calculated and analyzed.(3)According to the networking mode of the substation,comparative analysis of routing and equipment cost,proposed parameter configuration and board optimization scheme for optical transmission equipment of optical communication system in Hengjiang station.(4)Designed by optical transmission network,dispatch data network,and integrated data network,implement dual-route dual-channel service transmission in Hengjiang station.(5)Through the above optimization design,debug fiber optic cable and equipment,and data logging,analysis implementation and operation,evaluate the social and economic benefits.
