Impact of voltage dips on the operations of a high-power synchronous motor with a reactive power Controller
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2016, Vol 526, Issue 2
Abstract
The article presents the impact of voltage dips on the operations of a synchronous motor in the state of synchronism. The following characteristics were determined: static characteristics of the load angle depending on power voltage and excitation current for a GAe - 1716t/01 high-power motor. The results of simulation tests of dynamic states were presented. Finally, it was investigated whether it is justifiable to force excitation current during voltage dips in order to keep the motor in the state of synchronous work.
