Each of the plural power conversion apparatuses includes a power conversion circuit interconnected with a power system, a calculating unit 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, a storing unit configured to accumulate, in a storage device, time-series reactive power information which is information associating time and the at least one information calculated by the calculating unit, and a communication interface configured to transmit the time-series reactive power information stored in the storage device to the server. The server is constructed to collect the time-series reactive power information of each of the plural power conversion apparatuses via the communication interface.",
