Research On The Strategy Of Automatic Reclosing Of Fault Lines In The Parallel Path Of Photovoltaic Generation Part

The influence of the grid for grid photovoltaic power station at home and abroad is still in further analysis and argumentation,especially photovoltaic power station is according to the nature of the load input reclosing or according to the characteristics of the power supply in the problem of the reclosing and need further research.Combined with the actual fault data,this paper studies the strategy of automatic reclosing of the fault line in the grid-connection path of photovoltaic power station.Firstly,the purpose and significance of using automatic reclosing in power line are introduced.Secondly,the influence of grid-connected photovoltaic power station on line reclosing strategy and the problems to be solved are analyzed.Low voltage through the technical requirements of the photovoltaic power station is studied,not simple to pv line by the single power line or principle of double power lines reclosing setting pv power grid path line of reclosing,and gives the corresponding reclosing adjustment strategy.Based on the actual network frame of xinjiang aksu power grid,this paper presents and compares the actual operation effect before a nd after the improvement of reclosing strategy.Finally photovoltaic power station grid path fault line setting scheme of the implementation of the automatic reclosing,to improve the operation success rate index,aksu power grid reclosing reduce the disposal time power grid failure,improve power supply reliability and power grid safe operation has important significance.
