Title:
GRID LINKAGE FACILITY
Document Type and Number:
WIPO Patent Application WO/2017/145316
Kind Code:
A1
Abstract:
Provided is a grid linkage facility capable of suppressing harmonic voltages even when the circuit configuration differs in accordance with the conditions. This grid linkage facility is connected to a power grid and is equipped with: multiple power converters 14 connected to the power grid; multiple transformers 11 provided between the power grid and the power converters 14; multiple switches 12 provided between the transformers 11 and the power converters 14; and a controller 3 that controls the opening/closing of the switches 12. On the basis of a harmonic voltage content ratio characteristic, which is the relationship between the number of closed switches 12 and the harmonic voltage content ratio of the grid linkage facility 1, the controller 3 outputs an opening/closing command to the switches 12 such that the number of closed switches 12 is outside a closed-switch-quantity range, which is the range wherein the harmonic voltage of the grid linkage facility 1 increases.
