1. A design support device configured to support design of a power supply system in which power from a power supply is distributed and supplied to a plurality of load devices by a power distribution supply path in which a plurality of power cables are combined, the design support device comprising:
a first acquisition unit configured to acquire configuration information indicating a configuration of the power distribution supply path;
a second acquisition unit configured to acquire, for each of the plurality of load devices, operation pattern information representing an operation pattern of the load device;
a calculation unit configured to calculate, for each power cable of the plurality of power cables in the power supply system, a maximum current value, which is a maximum value of a current flowing through the power cable, based on the configuration information acquired by the first acquisition unit and the operation pattern information for the plurality of load devices acquired by the second acquisition unit; and
an output unit configured to output, for each power cable of the plurality of power cables in the power supply system, at least one of the maximum current value for the power cable and recommended cable information representing a cable recommended for use as the power cable based on the maximum current value for each power cable calculated by the calculation unit,
wherein the calculation unit is configured to:
generate first time series current data of a current flowing into each load device of the plurality of load devices based on the operation pattern information for each load device,
calculate, for each power cable of the plurality of power cables in the power feeding system, a second time series current data of the current flowing through the power cable by adding values of currents in the first time series current data for each load device connected to the power cable, and
determine a maximum value of the current in the second time series current data as the maximum current value for the power cable.
