# 一种考虑线路短时过载的断面输电能力提高方法A Transmission Capacity Improvement Method Considering Transmission Line Short-Time Overload

Abstract: The limit of thermal stability is an essential part of determining the transmission capacity of the transfer section. In the traditional safety analysis, the limit is a constant value. However, in the actual power operation, it is a process of the electro-thermal coordination closely relating to the environmental factors. Based on the above statements, the paper does a study on the process of the line current-carrying and then creates a model of thermodynamics of the line. After that, we combine the model with power analysis tools, as a result, forming a calculation model of power analysis. Finally, we test the thermal stability of the line in the short-time overload environment and verify the increase on the transmission capacity in consequence.
