CONTROL DEVICE, CONTROL METHOD OF SECONDARY EXCITATION DEVICE, AND VARIABLE SPEED PUMPED-STORAGE GENERATING SYSTEM |
| 摘要 |
According to one embodiment, there is provided a control device of a secondary excitation device which supplies a rotary machine with a voltage or current of a variable frequency. The control device includes a harmonic frequency calculation unit which calculates a frequency of a specific harmonic generated on a primary side of the rotary machine by using a slip frequency or rotation speed of the rotary machine and a carrier frequency of the secondary excitation device, and a carrier frequency correction unit which corrects the carrier frequency of the secondary excitation device such that the frequency of the specific harmonic calculated by the harmonic frequency calculation unit falls within a given band. |
