PROBLEM TO BE SOLVED: To provide a distributed power supply system and a control/protection device for the same capable of minimizing the occurrence of power failures and effectively using a power supply output to the maximum. SOLUTION: The distribution power supply system is provided with circuit breakers 11-13 connected to a distributed power supply 50, a system 81 and a load 85 respectively, current transformers 21-23 which detect respective currents n the system 81, the power supply 50 and the load 85, voltage transformers 31 and 32 which detect voltages in the system 81 and the power supply 50 respectively, and a control/protection device 40 which controls the circuit breakers 11-13, the distributed power supply 50 and the load 85 based on detected outputs by the voltage transformers 31 and 32 and the current transformers 21-23. In addition, a control and protection device 40 for the distributed power supply system 1 is provided. |
