The aim of the ship load flow and short circuit calculations is to determine whether the thermal and mechanical stresses on equipment, such as generators, cables, switchboards, and transformers, is below the maximum design values, under normal as well as contingency conditions.
It also gives information about the setting of transformer trappings and voltage regulators that ensures that the voltage levels on the different distribution buses and load terminals are within permitted stationary deviation limits.
Load flow calculations are performed to find stationary values of loads in the generation and distribution network, and since the network in ships normally are radial, it is a fairly straight-forward exercise.
It is normally done prior to the short circuit calculations in order to obtain its starting values.
