Abstract

The invention relates to a cable current-carrying capacity optimization method and device, computer equipment and a storage medium. The method comprises the following steps: processing the current current-carrying capacity by adopting a cable line system model, and obtaining the current of a cable metal sheath and the armoring current; Obtaining a current loss factor according to the current carrying capacity, the current of the cable metal sheath and the armoring current; Processing the current loss factor by adopting a cable current-carrying capacity model to obtain a current correction amount; Obtaining an absolute value of a difference value between the current correction amount and the current carrying capacity; When the absolute value is smaller than or equal to a preset value; confirming the current correction quantity as the current-carrying capacity of the cable; Therefore, the influence of the metal sheath and armoring of the submarine cable on the current-carrying capacity is fully considered; The current-carrying capacity of the submarine cable can be accurately acquired by taking the correction value as the current-carrying capacity of the submarine cable only when thecurrent correction value meets the condition, so that the current-carrying capacity of the submarine cable can be accurately acquired, and the safe and economic operation of the submarine cable can be ensured.

Description

technical field [0001] The present application relates to the technical field of submarine cables, in particular to a cable ampacity optimization method, device, computer equipment and storage medium. Background technique [0002] The current-carrying capacity of submarine cables is related to the selection of cable core cross-section, the selection of power transmission methods, the safe operation of submarine cables, and economic benefits. Therefore, accurate measurement of the current-carrying capacity of submarine cables is of great significance to the safe and economical operation of submarine cables. [0003] At present, the current ampacity of submarine cables is calculated using the calculation method recommended by the IEC 60287 standard. However, during the implementation process, the inventors found that there are at least the following problems in the traditional technology: the traditional technology cannot accurately obtain the ampacity of the cable, and thus ca...
