Introduction: To install a CAT-1 Transmission Line Monitoring system on a SHE Transmission line and demonstrate whether it can enable dynamic line rating resulting in safe and cost-effective line operation close to its thermal rating.

Objectives:

• Investigate the ease of integration of CAT-1 proprietary software with SHE Transmission’s SCADA system
• Evaluate levels of additional capacity achievable on the trial line through use of the installed CAT-1 equipment
• Verify the correlation between practical observations and the theoretical model already established
• Investigate the extent to which the technology can be applied without need for physical line uprating
• Estimate potential Capex and Opex savings from use of dynamic ratings based on the data obtained

Expected Benefits: The DLR system is intended to:

• Increase generation output and allow further generation connections to the 132kV circuit

• Raise Transmission capacity

• Monitor sag in order to provide advance warning of impending clearance violations

• Match line ratings to load and weather conditions.

The results of this project have potential for learning in the following areas:

• Potential savings in Capex and Opex

• Potential levels of additional transmission line capacity achievable by using the method

• Unforeseen challenges and risks associated with dynamic ratings

• Ease of integrating supplier proprietary systems with existing SCADA system

• Complexity of system planning required in case of wider adoption of the method

The learning will be disseminated by conference presentations.
