Dynamic Line Rating

Dynamic Line Rating (DLR) is a method used to determine the real-time capacity of power lines to carry electricity. Unlike traditional static line rating, which uses fixed factors like temperature and weather conditions, DLR adjusts the power line’s capacity based on current conditions like wind speed, air temperature, and sunlight.

Essentially, DLR helps power grid operators know exactly how much electricity a power line can safely transmit at any given moment. For example, on a windy day, the wind can cool the wires, allowing them to carry more electricity without overheating. This makes the grid more efficient and can help prevent power outages.

By using real-time data and sensors, DLR allows for smarter management of electricity transmission, making the system more flexible, efficient, and responsive to changing weather conditions, while reducing the risk of line failures or overloads.
