Info\NERC MOD\2023-MLPR2-MOD026
1.2 Field Measurements
1. ❑ Micro-Ohm Resistance Test,Value: mf2 @ 20°C
o Original Value is 0.***f2 @ **°C
o Manufacture Value is 1.1850 @ 25°C(This is a questionable value, very large but
maybe)
2. ❑ Review Final Rotor I Test Report,Value: Mfg
(Including Slip Rings,Initial Maintenance Record)
3. ❑ Complete final field measurements forms and save to SharePoint Site;
Plant Condition Assessment Library-All Documents
1.3 Equipment Verification
1. ❑Verify Unit Style Number:DECS-400-1-C-5-U
0 1=PSS
o C=125V(ac or dc)
o 5=5A CT Secondary
o U=Battery Backup for real-time clock.
1.4 Initial DECS400 Field Setup & Load DECS Settings File

5. ❑ Update Field Rated Data with field DLRO Testing values.Use IR to measure
temperature of the rotor not just the ambient air for temperature measurement.
1.5 IRIG & Networking Setup
1. ❑Verify IRIG physically Connected and Setup the IRIG Settings and adjust for MST.
a. Communications->NTP Settings
❑Set the IP address to the NTP(Clock:unknown)

❑ Perform a final walkdown prior to spinning and flashing the field.
1. ❑ Switch to FCR Mode
There have been times when the current is not enough and the unit will fail to build.
Review the open circuit saturation results from the manufacture or previous testing.In
2017 data was collected and the field current was 287A,at 1.6MVA unity loading.83A
may not cut it as noted from the Basler manual.
2. Go to Settings->AVR/FCR/FVR
a. Adjust Field Current Regulator(FCR)
i. ❑ Setpoint(20%)=415A x 0.20=83A
ii. ❑ FCR Pre-position 1(20%)=83A
iii. ❑ FCR Pre-position 2(20%)=83A
3. Manually Start the DECS400(generator should build to percentage of rated voltage)
a. ❑ Use a fluke to verify the voltage is firing correctly.
May need to raise the voltage if 20%is not sufficient,see step 4.
b. ❑ Capture all diodes firing within the waveform and record.
4. ❑ Increase the field current until 100%rated terminal voltage is reached.
a. The OEL limiter should limit the current to Rated Field Current x 75%=311A(Or
use past MOD data, refer to the initial settings tables).
According to Limiters->Summing Point OEL.Adjust this if needed.
b. Record the:
i. No load field current: A
ii. No load field Volts: V
c. Manually adjust the voltage to 2%above rated. 13.8kV x 1.02=14.076kV,this
will provide the field current required for manual step responses in FCR mode.
i. Rated+2%field current: A
ii. (Rated)/(Rated+2%)_ %
5. Go to Meter->Operation
a. Verify the phase angle,positive and negative sequences to make sure values look
correct.

Idaho Power MLR2—Initial Setup&FCR/AVR Commissioning Procedure
i. ❑There should be little negative sequence values,if there are,a CT or
PT might be rolled.
ii. ❑ General review of field current and generator voltage.
iii. ❑ Verify any protective relays are reading correct.(SEL-751A)
6. ❑Verify the field temperature appears accurate.= C at startup
7. ❑ Verify the phasing looks accurate.
