<p>PROBLEM TO BE SOLVED: To suppress voltage fluctuation of a plurality of wind power generators arranged in a remote location and facilitate operation continuance of wind mills, in order to solve the problem that in a wind farm with a wind power generation system, a risk that a synchronization phenomenon occurs gets higher, and thereby it is difficult for operation continuance at the time of voltage drop from an electric power system side.SOLUTION: When voltage of an electric power system is an abnormal value, correlation of voltage fluctuation between a plurality of wind power generation systems constituting a wind farm is calculated, and it is determined whether a synchronization phenomenon occurs. Consequently, a pitch angle of a blade is changed with respect to a wind power generation system contributing to the synchronization phenomenon.</p> |
