考虑实时气候对于输电线路载流量的影响
Influence of Real-time Climatic Conditions on Ampacity of Power Transmission Line
摘要
Abstract
Due to different calculation standards in different countries and influence on ampacity of the transmission line by different climatic conditions, the calculation results are often different.GB 50545-2012 standard and IEEE Std 738 TM-2012 standard is respectively used for calculating ampacity of the transmission line in domestic and at abroad, therefore, this paper compares and analyzes calculation models for ampacity in these two standards.On these two models, it uses real-time climate data about one 500 kV line to calculate and analyze carrying ampacity in winter and summer as well as in specific climatic conditions.It also studies influence of different climatic factors on ampacity of the transmission line.Results indicate real-time climatic conditions are more available in accurately working out ampacity of the line and making full use of carrying capacity of the conductor on the premise of ensuring its safe operation.In addition, wind speed has largest influence on ampacity of the transmission line while sunlight intensity has smallest influence.关键词
