- 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.
- 在研究汽轮发电机端部瞬态涡流场、端部绕组电动力的基础上, 本文对汽轮发电机端部绕组的振动进行了全面分析.文中以1台32MW汽轮发电机作为实例, 对发电机在冲击负荷下端部绕组所受到的电动力以及由此引起的强迫振动情况作了实例分析, 得出了一些有益的结论.文中还对端部绕组在假想故障下的振动情况作了模拟分析, 以便进一步了解发电机端部绕组的振动规律, 为提出改善绕组振动的对策提供了理论依据.
