This research proposal deals with the application of advanced mathematical techniques for calculation of the current currying capability of electric power cables. The following are the areas to be addressed: 1. Optimal ampacities for groups of unequally loaded, dissimilar cables. 2. Development of rating methods for cables laid in a "utility sidewalk" installation. This is a new trenchless technology that is being developed and there are no ampacity calculation methods available. 3. Development of installation guides for circuits with multiple cables per phase. Optimization and artificial intelligence methods will be applied. 4. Algorithms for transient rating calculations with arbitrary starting temperatures. All existing methods are based on either ambient or steady-state starting temperatures. In practice, emergency calculations are required for arbitrary starting temperatures reflecting in-situ measurements. 5. Advanced numerical studies to determine the external thermal resistance of touching cables with heavy sheath circulating currents.

本研究计划应用先进的数学方法计算电力电缆的载流能力。以下是需要解决的问题：1。适用于负载不均匀的不同电缆组的最佳载流量。2.在“公用设施人行道”装置中敷设的电缆的额定方法的发展。这是一种正在开发的新的非开挖技术，目前尚无载流量计算方法。3.开发每相多电缆电路的安装指南。将应用优化和人工智能方法。4.具有任意起始温度的瞬态额定值计算算法。所有现有的方法都是基于环境或稳态起始温度。在实践中，需要对反映现场测量结果的任意起始温度进行应急计算。5.确定具有大护套环流的接触电缆的外部热阻的高级数值研究。
