<P>PROBLEM TO BE SOLVED: To provide an electric power conversion device that suppresses wrong determination on individual operation. <P>SOLUTION: The electric power conversion device converts DC electric power into AC output electric power and sends the output electric power to an electric power system in linkage with the electric power system. The electric power conversion device includes an individual operation determination part which gives active change to the output electric power and determines that the individual operation starts based upon a value of a parameter associated with the current state of electric power at a linkage point. The individual operation determination part determines that the individual operation starts when a determination condition in which a value of frequency of a voltage as one kind of parameter is preset is satisfied and when a determination condition in which a value of another kind of parameter is preset is satisfied. <P>COPYRIGHT: (C)2013,JPO&INPIT |
