Abstract

A DC/DC converter (11) converts the DC current generated in solar power generation equipment to the DC current of a prescribed 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 power system (15) via a system interconnect switch (14). When the system voltage of the power system (15) is abnormal a control device (20) opens the system interconnect switch (14) to switch the operation mode of the DC/DC converter (11) and inverter (12) to self sustaining operation without suspending the DC/DC converter (11) and inverter (12) and supplies electric power to a load (17) connected between the inverter (12) and the system interconnect switch (14).
