Active Power Control Set-point Ramp Rate of 20% of Registered Capacity per minute is applied in the WFCS Yes / No Wind Following Ramp Rate of 20% of Registered Capacity per minute is applied in the WFCS Yes / No Where NCC has control of the reactive power, ensure WFPS is exporting close to 0 Mvar at the connection point by bringing kV set-point = system voltage in 1 kV steps. Yes / No / N/A If the WFPS has Emulated Inertia, note Emulated Inertia Status Turn Emulated Inertia OFF Pre-test status: ON / OFF / N/A Emulated Inertia Status: ____ Ramp Rate Calculations Calculation Value Active Power Control Set-point Ramp Rate of 20% of Registered Capacity per minute ____ MW/min (WFPS to specify calculation and formula used) Wind Following Ramp Rate of 20% of Registered Capacity per minute ____ MW/min (WFPS to specify calculation and formula used) If WTGs are out of service, will the WFPS ramp at a reduced ramp rate? ____ MW/min (WFPS to specify calculation and formula used) Ramp Rate Settings Mode Rate Priority Frequency Response As fast as technically possible. 60% of its expected Active Power response within 5 seconds 100% of its expected Active Power response within 15 seconds. 1 Active Power Dispatch 20% of Registered Capacity per Minute 2 Wind Following 20% of Registered Capacity per Minute 3
Ramp Rate Settings Both Active Power Control Set-point Ramp Rate and Wind Following Ramp Rate are adjusted between 1% and 100% of Registered Capacity per minute, with ramps carried out at each ramp rate. Step No. Action Time Comments 1 WFPS begins data recording for all trends noted in Section 7.3, above Operator Name ____________ Date ____________ 2 WFPS requests permission from NCC to proceed with the Ramp Rate Settings test and confirms the following with NCC: AAP of the WFPS MW output of the WFPS APC is OFF Frequency Response is OFF Frequency Response is in Curve 1 ____ MW ____ MW Status ____ Status ____ Curve ____ 4 WFPS requests NCC to turn APC ON and issue a of [insert 30% of Registered Capacity] MW and waits until 3 minutes after the set-point has been achieved AAP =____ MW MW Output =____ MW 5 WFPS sets the Active Power Control Set-point Ramp Rate to 1% of Registered Capacity per minute confirms the following to NCC: Active Power Control Set-point Ramp Rate is now 1% of Registered Capacity per minute ____ MW/min 6 WFPS requests NCC to issue a set-point of [insert 35% of Registered Capacity] MW and waits until 3 minutes after the set-point has been achieved WFPS shall ramp to the new over 5 minutes AAP =____ MW MW Output =____ MW 7 WFPS sets the Active Power Control Set-point Ramp Rate to 100% of Registered Capacity per minute confirms the following to NCC: Active Power Control Set-point Ramp Rate is now 100% of Registered Capacity per minute ____ MW/min 8 WFPS requests NCC to issue a set-point of [insert 20% of Registered Capacity] MW and waits until 3 minutes after the set-point has been achieved WFPS shall ramp to the new over 9 seconds AAP =____ MW MW Output =____ MW 9 WFPS sets the Active Power Control Set-point Ramp Rate to 20% of Registered Capacity per minute confirms the following to NCC: Active Power Control Set-point Ramp Rate is now 20% of Registered Capacity per minute ____ MW/min
5 WFPS ends data recording 6 WFPS informs NCC that the Shutdown and Start-up test is complete. If further testing is not being completed, go to Section 8.5 Return to Standard Settings Note any issues or deviations from test procedure For example changes in step size, duration, test operators, parameter changes on site Mark as “No Comment” if test proceeded as per procedure. Return to Standard Settings The WFPS settings are returned to standard following completion of the Active Power Control Test. Step No. Action Time Comments Operator Name ____________ Date ____________ 1 WFPS confirms the following with NCC: AAP of the WFPS MW output of the WFPS APC is OFF APC Set-point = [insert 100% of Registered Capacity] MW Frequency Response is ON Frequency Response is in Curve 1 Frequency Droop Setting is 4% WFCS frequency reference is system frequency Emulated inertia Status is returned to pre-test status as noted in Section 6.4 ____ MW ____ MW Status ____ ____ MW Status ____ Curve ____ ____% Frequency Reference __________ EI Status 2 WFPS informs NCC that Active Power Control testing is complete Note any issues or deviations from test procedure For example changes in step size, duration, test operators, parameter changes on site Mark as “No Comment” if test proceeded as per procedure
