Title:
電力変換システム
Document Type and Number:
Japanese Patent JP7054653
Kind Code:
B2
Abstract:
Provided is a power conversion system that can converge generator oscillations at an early stage, without causing control interference or the like to be generated. This power conversion system is connected to a three-phase power grid, and is provided with: a control unit that extracts the oscillation component of a first reactive power which is output by a generator connected to the power grid, and that outputs a command signal corresponding to the oscillation component; and a power conversion unit that, in accordance with the command signal, generates a second reactive power which cancels out the oscillation component of the first reactive power, and outputs the second reactive power to the power grid.
