POWER CONTROL METHOD AND DEVICE

摘要

The present invention discloses a method and an apparatus for power control. An apparatus for power control in accordance with an embodiment of the present invention can include: a voltage comparing part configured to compute an error voltage by using a measured voltage measured at the generator and a reference voltage that is designated; a control module configured to compute a first reactive power value for power control of the generator by being inputted with the error voltage; and a driving module configured to compute a reference reactive power value by using the first reactive power value and a second reactive power value computed using an active power value of the power converter and configured to control the power converter in correspondence with the computed reference reactive power value. The present invention can realize a reliable and efficient power generation system without incorporating an additional device or process, thereby achieving a stable quality of electric power and a reliable operation of the power generator.
