How to choose the power of diesel generator set

The capacity of the diesel generator set is limited. Unlike the power grid, the starting current of the load must be considered. Therefore, it is not entirely correct to choose the total power of electrical appliances as the power of purchasing diesel generator sets. For example: a 30KW motor uses star-delta starting, the starting current will be 4 to 6 times the rated current, at least a 120KW diesel generator set can be used to start this motor normally. Different starting methods will have different starting currents. For example, the soft starter will only generate 2 to 3 times the starting current. The inverter starts steplessly and there is no starting surge current. Also, whether the electrical appliance is loaded when starting, also determines the size of the starting current. It is necessary to fully understand the specific electrical conditions to calculate the required diesel generator set power more economically, and to avoid calculation errors and buy back unusable situations.
