Abstract: According to the poor transportation system of the remote islands and locations or the problems such as the remote isolation failure in an emergency, the article puts forward an automated construction mode of the remote island distribution network based on the beidou communication in order to solve the blinding adjustment problem of the remote island distribution network and reduce the numbers and scopes of the power failure. The construction mode cuts down the time of emergency repair and power failure. It takes the automation construction of zhoushan remote Island distribution network as an example. The whole overhead line is equipped with primary and secondary fusion switches based on the beidou communication, and uses the technology of the beidou short message communication to connect the informations of the three remote to the new generation distribution automation master station system so as to realize the all-weather supervision and control of the remote island distribution network equipment and speed up the analysis and isolation of faulty lines.
