DISTRIBUTED POWER SYSTEM AND OPERATION METHOD |
摘要 |
[Problem] To provide a distributed power system capable of continuously supplying electric power to a load even when a system voltage of the electric power system becomes abnormal. [Solution] A DC/DC converter (11) converts DC current generated by solar power generation facility to DC current with a predetermined output voltage, and an inverter (12) converts the DC current converted by the DC/DC converter (11) to an AC current which is output to a electric power system (15) via a system interconnect switch (14). When the system voltage of the electric power system (15) is abnormal, a control device (20) makes the system interconnect switch (14) open to switch operation modes of the DC/DC converter (11) and inverter (12) to a self-sustaining operation without stopping the DC/DC converter (11) and inverter (12), and supplies electric power to a load (17) connected between the inverter (1) and the system interconnect switch (14). |
