Abstract:Based on the least square fitting method and difference compensation method,the jumper design method is optimized for 1000 k V UHVAC single-circuit transmission line. A new design method is put forward to simplify the installation and design of jumpers,which can avoid the repeated calculation of transmission line tower size,rotation degree,length and inclination angle of insulator strings etc because of boundary condition changes in the conventional " exhaustive algorithm". The proposed mentod can effectively enhance the design efficiency and design quality for jumpers.
