Research On Cause And Division Method Of Bird Damage In Inner Mongolia

In recent years,bird damage has became a major factor affecting the Inner Mongolia power grid safe and stable operation,because an increasing share in the tripping caused by birds in Inner Mongolia power grid fault tripping.Although all power supply bureau,electric power bureau power transmission management departments have carried out a large number of bird damage prevention work,the effect received is little.So,drawing in Inner Mongolia electric power system bird area division is very necessary.After that we can pay focused and important attention to bird damage prevention work and improve the anti bird device efficiency.Due to the more assessment efforts made by Inner Mongolia electric power company on line fault in recent years,the directly Bureau of the company make more efforts to the prevention and control of bird,and the bird damage fault rate of high voltage transmission decreased.However,Extraordinary high voltage transmission line bird damage fault rate is increasing year by year.In view of this situation,we propose a method to divide out the bird in key areas by drawing distribution map of bird hazard area,and accomplish key management in the important bird area tower.Do the best work in the right location.So we must draw the Inner Mongolia autonomous bird damage region level distribution map and collected and analyses simply the bird damage classification method research at home and abroad.These work has a certain guiding significance to the study of the thesis in the area.In this paper,first of all,we have a simple understanding of comprehensive evaluation method,and know that this method can comprehensively evaluate various influencing factors;then we establish comprehensive evaluation model based on various factors influencing bird damage and selected influencing factors.Though the comprehensive evaluation model,we calculate the weight coefficient of each factor,and sort theses factors according to the weight coefficient size.Finally,we sum the bird damage factors based on vector and divide the bird damage grade with the bird damage impact factor vector value.
