10.3.4 Generate Configuration Files
Use the Excel commissioning tool called ‘Commissioning_Document_v1.2’ to generate
the required OLTC configuration files. The spreadsheet takes the following inputs:
• The tap position movements in the form of raw CSV data (as output by
Perception in Section 10.3.3)
• The ‘through positions’ of the tap changer
This data is used to produce the tap position map and the motor torque configuration
files, output in the form of TapPositionCalibration.cfg, OltcGroups.cfg and
OltcRefData.cfg. To use the tool, perform the following steps:
1. Start Microsoft Excel and open the Commissioning_Document_v1.2 as shown in
