METHOD FOR SYNCHRONIZING EXCITED SYNCHRONOUS MACHINE WITH SUPPLY MAINS (VERSIONS)

摘要

electrical engineering; reducing time required to ideally synchronize synchronous machine and throw it on line. SUBSTANCE: method involves following procedures: machine connected to supply mains is excited at it approaches subsynchronous frequency; then continuous variation of voltage exciting synchronous machine is set so that with such variation it can cross supply frequency; after this transfer phase coincidence is predicted and at this moment excited synchronous machine is thrown on line. EFFECT: reduced synchronization time. 4 cl, 2 dwg
