摘要（英）：

The invention relates to the technical field of parameter setting of subsynchronous oscillation damping controllers, and discloses parameter setting equipment and method for the subsynchronous oscillation damping controller. The subsynchronous oscillation damping controller comprises a modal filter and control equipment, wherein the modal filter is used for carrying out filtration on a rotating speed signal of a generator set to obtain a corresponding modal signal; the control equipment is connected with the modal filter and is used for achieving control on subsynchronous oscillation according to the modal signal; the control equipment comprises a compensation device; and the compensation device is connected between the modal filter and the control equipment, and is used for carrying out setting according to the filtered modal signal. The modal signal output by the modal filter is set through the compensation device which is connected with the modal filter in the subsynchronous oscillation damping controller in series; the accuracy of parameters in the subsynchronous oscillation damping controller is improved; and the subsynchronous oscillation damping controller can relatively well suppress subsynchronous oscillation, so that the generator set can be relatively well protected.
