Motor start-up
Thread Content
There is currently a standalone power supply with a capacity of 500 KW and a voltage of 400 V. What is the maximum power of motors, centrifugal compressors, and reciprocating compressors that can be used with it? If a motor with a power of around 130 KW is used, can this issue be resolved by installing a soft starter?
Experts, should this issue be reviewed?
This requires calculating the starting voltage drop and the busbar-side voltage drop based on the characteristics of the equipment in order to determine it
It depends on the length of the circuit and the cable selection; if the voltage drop is within acceptable limits, soft starting can be used to address the issue
A 500KW generator with a 130KW motor for reduced-voltage starting should work fine; however, the other loads connected to the generator should not be too heavy. For specific calculations, refer to the section on diesel generator capacity calculation in “Matching Four”.
Low-voltage starting is no problem; it mainly depends on whether you have any other loads
Using reduced-voltage starting is no problem.
