    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: In a power generation apparatus equipped with an AC energization synchronous generator, when energization of a secondary winding starts to conduct connecting to the network of the AC energization synchronous generator to a network voltage, energization of the secondary winding starts at a fixed frequency and a slip frequency is calculated from a difference between a frequency of the network voltage and a resultant stator voltage frequency. Thereafter, energization starts at the calculated slip frequency and a voltage having a frequency generally coincident with the network frequency is output to the stator to incorporate the generator to the network. A phase is adjusted to make zero a phase difference when the rotation speed changes or the phases become different.

    摘要: Because of the necessity of resolver for detecting a rotating position, which is very expensive, and noise suppression of the rotating position signal line on a doubly-fed machine, cost increase of the generator and reduced reliability due to possible failures are inevitable. In order to solve such problem, a generation system in the present invention is equipped with an exciter that estimates the slip frequency of the doubly-fed machine from each primary current I1 and voltage V1 and secondary current I2 and voltage V2 of the doubly-fed machine and excites the secondary of the doubly-fed machine at the estimated slip frequency.
