摘要：

The overhead line rating methods have a double requirement: accuracy and security. A method is accurate if the forecasted rating is close to the actual rating. It is secure if the forecasted rating is lower or equal to the actual rating. This paper compares several overhead line rating methods in terms of accuracy and security based on the results of a pilot project. Indicators for the conductor temperature exceedance and the rating underestimation are used to compare the rating methods. The static rating, the ambient-adjusted rating and the rating based on weather forecasts are analyzed.
