本文首先介绍了限制输电系统功率传输能力的主要约束，以及现有的方法来减轻这些约束，如输电线路的提升/升级技术。它还讨论了主要的可行性问题，需要解决的目的是评估时，应推荐一个上调/升级的解决方案。在此基础上，介绍了输电线路电压和热功率提升的有效性、所需的技术分析和常用方法。最后，强调了动态热耗率监测是一个很好的热升级解决方案，并介绍了其商业化的技术。
This paper initially describes the main constraints that limit the transmission system power transfer capability, as well as the existing methods to alleviate these constraints, such as transmission line uprating/upgrading techniques. It also discusses the main feasibility issues that need to be addressed aiming to evaluate when an uprating/upgrading solution should be recommended. After that, aspects of effectiveness, required technical analysis and usual methods for transmission line voltage and thermal uprating are presented. Finally, the dynamic thermal rate monitoring is emphasized as a good thermal uprating solution and its commercially available technologies are presented.
