The utility model discloses a public line distributed generator intelligent management system, the anti - power transmission problem of public line and the electric power system that have solved small-scale power in connecing haul oneself willingly into the problem that allies oneself with the system of cutting main switch and reduce public line power supply reliability fully, have realized the purpose to public line distributed generator and network state remote monitoring. The technical scheme who adopts does: a public line distributed generator intelligent management system, the public line is the 220380V shared line, connect through the wire between distributed generator and the public line, and has set gradually the switch that is incorporated into the power networks, the electric energy meter that is incorporated into the power networks, intelligence be incorporated into the power networks switch, disconnected electric sensor, service entrance switch, the total service entranceswitch of customer and switch on this wire, the service entrance switch of service entrance switch for taking the automatic coincidence function of decompression dropout, the service entrance switch of switch for taking the automatic coincidence function of decompression dropout is incorporated into the power networks, disconnected electric sensor and intelligence are incorporated into the power networks, and the switch passes through the circuit and data collection station is electric is connected, communicate through wireless between data collection station and the handheld terminating machine.
