The Research of Frequency-Controlled Synchronous Drive Transient Processes

摘要

A mathematical model is presented and characteristic transient processes in synchronous motors of variable frequency drives associated with load acceptance and shedding, changes of power supply voltage and frequency and drives speed adjusting are considered. The results can be useful in studying the features of synchronous drive adjustment as well as in the formation of requirements for reconstruction of synchronous drives of gas compressor units at compressor stations and pump units at oil pumping stations of main pipelines.
