摘要:

电晕损耗是1 000 kV特高压交流输电线路导线选择的重要影响因素。探讨国内外主要的电晕计算方法进行,以实际工程为依托,采用博纳维尔电力管理局(BPA)公式计算1 000 kV特高压交流线路在不同天气条件下的电晕损耗及年综合平均电晕损耗,并对电晕损耗与电阻损耗的关系进行比较。探讨的计算方法和计算结论可为特高压交流输电线路导线选型设计提供参考。

Abstract:

Corona loss is the important factor in the conductor selection criteria for 1 000 kV UHVAC transmission line. In this paper, the popular corona loss estimation theory is discussed. Based on a practical project, the corona loss is calculated using Bonnevile Power Administration (BPA)model, in which the weather condition is considered. The relationship between corona loss and resistance loss is compared thereafter. The research results could be referenced for future designation on the type of UHVAC transmission line.

Key words: UHVAC, corona loss;conductor selection
