    摘要： A wind power generation system includes: a wind turbine in which at least one blade is mounted on an axis; a generator for generating multiphase alternating current power by rotation of the axis; and a multiphase power conversion device for performing PWM-control for adjustment and output of generated power of the generator. With the configuration, the PWM-control provides for each phase a control paused period in which no overlap occurs. Thus, the pulse density between the control period and the control paused period of other phases is low, thereby generating high and low density in an inter-phase pulse.

    摘要： A power generation system is disclosed for supplying power to an electrical grid. The system comprises a synchronous machine and coupling means for coupling the synchronous machine to a prime mover. Control means are provided to control the system such that the system is selectively operable in two modes. In the first mode, the synchronous machine is coupled to the prime mover and acts as a synchronous generator to supply power to the grid. In the second mode the synchronous machine is decoupled from the prime mover and acts as a synchronous condenser. This can allow parameters of the grid, such as power factor and voltage, to be adjusted.
