DYNAMIC LINE RATING (DLR) SYSTEM
The DLR system featured a Transmission line dynamic line rating and forecasting, Transmission line clearance monitoring, and line conductor temperature monitoring.
Features and Specifications:
Increase overhead line thermal capacity of between 10%-50% +more capacity, 95% of the time
Mitigation tool for transmission congestion
Increased transmission capacity at minimal investment
Increased situational awareness for operators
More efficient integration with renewables such as solar energy
The DLR system can be utilized in situation whereby transmission network constraints under contingency becomes an operational limitation.
In some cases, the limitation imposes generation constraints, which could lead to operational inefficiencies. The limit can be stretched by applying dynamic rating to selected lines which will bring in significant operational cost saving.
