Claim 0:
1. A power conversion apparatus comprising:
a power conversion circuit interconnected with a power system;
a calculating unit that is configured to calculate, based on an output current and an output voltage of the power conversion circuit, at least one information of reactive power and a reactive current output by the power conversion circuit; and
a storing unit that includes a storage device and is configured to accumulate, in the storage device, time-series reactive power information which is information associating time and the at least one information calculated by the calculating unit,
wherein the time-series reactive power information is information further associating year, month, and day with the time and the at least one information calculated by the calculating unit,
wherein the at least one information includes information associating, with the time, each of an instantaneous value and an integrated value with respect to each of the reactive power, the reactive current, and a reactive voltage output by the power conversion circuit.
