<p>The control section includes a PI controller (103) that calculates and outputs an active current instruction value I q * by proportional-plus-integral control to perform proportional integration of a deviation between the value V dc of a DC voltage outputted from the converter section and a DC voltage instruction value V dc *, a PI controller (105) that calculates and outputs an active voltage correction value by proportional-plus-integral control to perform proportional integration of a deviation between the active current instruction value I q * from the PI controller (103) and the value I q of an active current inputted to the converter section, and a PI controller (108) that calculates and outputs a reactive voltage correction value by proportional-plus-integral control to perform proportional integration of a deviation between the value I d of a reactive current inputted to the converter section and a reactive current instruction value I d *. The control section makes the active current instruction value I q * outputted from PI controller (103) zero or negative and operates the PI controller (105) by proportional control in a period from beginning to completion of startup of the converter section.</p> |
