Study on Electromagnetic Force and Vibration of Turbogenerator End Windings under Impact Load(Ⅱ):Analysis of Vibration of End Windings under Impact Load
摘要
Abstract
On the basis of the study of transient eddy current field in the end region of turbogenerator and electromagnetic force of end-region winding, this paper analyzes the electromagnetic vibration of the turbogenerator roundly. A 320 MW turbogenerator is taken as an example to specify the electromagnetic force of end-region winding and therefore the vibration in the case that the generator is affected by impact load. Some conclusions are drawn on the basis of the specification. Vibration of windings under imaginary faults is simulated, so that the vibration law of the end winding of turbogenerator can be studied further. On the basis of this, the countermeasure against winding vibration can be advanced.关键词
