A wind power generation system in which a parallel-type inverter is employed is provided to reduce the current ripple and torque ripple of a generator by delaying synchronizing signal applied in first and second converter control parts for a predetermined time. A wind power generation system in which a parallel-type inverter is employed comprises: first and second converter control parts(24,26) controlling first and second converters(16,18); first and second inverter control parts(28,30) controlling first and second inverters(20,22); and a synchronous signal generator(35). The synchronous signal generator produces synchronizing signals delayed for a designated time. The delayed synchronizing signal is delivered to the second inverter control part and the second converter control part. The synchronous signal generator produces the synchronizing signal without control signal and time delay. The synchronizing signal without the time delay is delivered to the first converter control part.
