In the present invention, resonance suppression devices have a current command value generation unit described in detail below and are connected in parallel at desired connection points (installation points) on a power line that connects a power supply system and a wind farm. The current command value generation units generate a current command value by: subtracting a voltage obtained by multiplying a harmonic component Vh of a measured system voltage VS by a second transfer function (KV); and adding, using an adder, a current obtained by multiplying a harmonic component of a current Is supplied from a power facility on the side including a resonance point by a first transfer function (KS). The generated current command value is input to a power conversion device, a compensation current is output from the power conversion device to a power system, and resonance is thereby suppressed. |
