Abstract

The present invention relates to a simulation calculation method for thermal stability of a ship cable. The method comprises the following steps of: performing statistical analysis and classification on current laying forms of a main cable on a conventional submarine, and determining 4 typical arrangement modes; determining a main parameter that influences thermal stability calculation of the cable; separately modeling the 4 typical arrangement modes; establishing a cable cross section model by using ansys software, applying a ring-shaped layer, and setting a layer position in the cable as a node, applying a radiant heat load to the node, and loading the main parameter of the cable on the node; and according to the established model, by pre-processing for the thermal stability calculation during long-time operation of the cable and post-processing for the thermal stability calculation during short-circuit current impact, calculating the thermal stability of the ship cable. The method provided by the present invention solves the problems that manual calculation is error-prone, a large amount of labor and time need to be consumed, and real-time property and accuracy are difficult to meet; and the method provides technical guidance for the construction and design of the main cable laying of the conventional submarine.

Description

technical field [0001] The invention relates to a submarine system simulation technology, in particular to a simulation calculation method for the thermal stability of a marine cable. Background technique [0002] In the construction design of the conventional submarine power system, in order to ensure the reliability and safety of the power system and the stability of the whole ship's power grid, it is necessary to calculate and analyze the thermal stability of the cable. Analyzing the thermal stability of marine cables in working conditions can provide the basis or check for the selection of conventional submarine cables. The analysis and calculation of thermal stability is of great significance to the safety of conventional submarines. [0003] At present, the method of combining manual calculation and estimation is mostly used in China to estimate the thermal stability of cables. With the deepening of design work, manual calculation can no longer meet the requirements o...
