这是第二部分的调查，旨在提供一个彻底的技术比较传统和替代架空输电线路的基础上的负载能力的特点。前一部分概述了负载能力分析的基本原理，并将其应用于三条可比较的单回路线路。在第二部分中，分析扩大到三个可比的双回线：传统的三相交流双回线（假设为比较的参考系统）和双极高压直流输电线路和非常规的交直流联合线路。与第一部分一样，负载能力分析考虑了热极限、电压降、功率损耗，以及稳态和瞬态稳定性（如果可行）。第二部分还对单回路和双回路配置的不同系统进行了总体比较，得出最终结论。
This is the second part of an investigation aimed at providing a thorough technical comparison between traditional and alternative overhead power transmission lines based on the loadability characteristics. The previous Part I outlined and applied the fundamentals of the loadability analysis to three comparable single-circuit lines. In Part II, the analysis is broadened to three comparable double-circuit lines: traditional three-phase ac double-circuit lines (assumed as the reference system for the comparison) and bipolar HVDC lines and nonconventional combined ac-dc lines. As in Part I, the loadability analysis takes into account thermal limits, voltage drop, power losses, and - when feasible - steady state and transient stability. Part II also performs an overall comparison among the different systems in single-circuit and double-circuit configuration to draw final conclusions.
