수결구특점、공작조건등제다인소영향，기륜발전궤조발전궤전자적진동원인비상복잡。침대모200 MW궤조발전궤전자대수후수차계동중출현적진동문제，분별진행료분석진단화처리，최종해결료발전궤조적진동문제，병대발전궤진동적방치조시진행료총결。
Because of the differences in structural characteristics and working conditions, the causes of generator vibration are always complicated. Vibration problems appeared after the generator rotor had been overhauled on a 200 MW steam turbine generator. As for these problems, better effect of vibration relief was achieved by making accurate analysis and management, finally solved the vibration fault, and prevention or control measures on vibration of turbo-generator were summarized.
