Study Of The Software System For The Design Of Setting Fiber Optical Cables On Power Towers

With the rapid progress of the economy since reformation and opening, The construction of electric power system has been greatly developed, which brings us a kind of transmission resources all over the country. It is very important to find a way to use the resources sufficiently .One of the best way is setting ADSS on the power towers and building a large communication net, it can make great benefits to the economy and our society.While in recent years, we find some problems in ADSS projects. ADSS fiber optical cables are eroded and power towers are destroyed by the additional loads of ADSS. In order to solve these problems and avoid loss, we need to research and develop a software system to assist the design for ADSS setting.After studying the recent research results and summarizing practical experiences ,the author develop a software of computation and design based on the principle of integration .This software consists of three subsystems (preprocess,computation and postprocess),with the support of database module. Users can model, compute and analyze with this software conveniently and the whole system is developed with Visual Fortran,VC++, OpenGL ,SQL Server.In the computation part, the main body of this software, the author use Charge Simulation Method to analyze the electromagnetic field distribution on each section of transmission lines and the potential and intensity along ADSS concerned 3-D effects.Also,Finite Element Method is used to analyze the structure of power towers.Some unordinary loadcases, such as galloping and transmission lines corner etc., are concerned and the subsystems are coupled .The results are provided by figures of element color,isoline, contour with data-output . It can help users to choose the best suspension point for ADSS and find a way to strengthen power towers .It is helpful in design.
