Reference: IEC 61400-27-1:2015, Annex D.

Attributes

Name Type Description
dprefmax PU Maximum ramp rate of pWTref request from the plant controller to the wind turbines (dprefmax) (> WindPlantFreqPcontrolIEC.dprefmin). It is a case-dependent parameter.
dprefmin PU Minimum (negative) ramp rate of pWTref request from the plant controller to the wind turbines (dprefmin) (< WindPlantFreqPcontrolIEC.dprefmax). It is a project-dependent parameter.
dpwprefmax PU Maximum positive ramp rate for wind plant power reference (dpWPrefmax) (> WindPlantFreqPcontrolIEC.dpwprefmin). It is a project-dependent parameter.
dpwprefmin PU Maximum negative ramp rate for wind plant power reference (dpWPrefmin) (< WindPlantFreqPcontrolIEC.dpwprefmax). It is a project-dependent parameter.
kiwpp Float Plant P controller integral gain (KIWPp). It is a project-dependent parameter.
kiwppmax PU Maximum PI integrator term (KIWPpmax) (> WindPlantFreqPcontrolIEC.kiwppmin). It is a project-dependent parameter.
kiwppmin PU Minimum PI integrator term (KIWPpmin) (< WindPlantFreqPcontrolIEC.kiwppmax). It is a project-dependent parameter.
kpwpp Float Plant P controller proportional gain (KPWPp). It is a project-dependent parameter.
kwppref PU Power reference gain (KWPpref). It is a project-dependent parameter.
prefmax PU Maximum pWTref request from the plant controller to the wind turbines (prefmax) (> WindPlantFreqPcontrolIEC.prefmin). It is a project-dependent parameter.
prefmin PU Minimum pWTref request from the plant controller to the wind turbines (prefmin) (< WindPlantFreqPcontrolIEC.prefmax). It is a project-dependent parameter.
tpft Seconds Lead time constant in reference value transfer function (Tpft) (>= 0). It is a project-dependent parameter.
tpfv Seconds Lag time constant in reference value transfer function (Tpfv) (>= 0). It is a project-dependent parameter.
twpffiltp Seconds Filter time constant for frequency measurement (TWPffiltp) (>= 0). It is a project-dependent parameter.
twppfiltp Seconds Filter time constant for active power measurement (TWPpfiltp) (>= 0). It is a project-dependent parameter.
