The stator core resonance of hydro-electric generator caused by negative-phase-sequence current is a new problem encountered in recent years in this country, and to our knowledge, scarcely known abroad. In this paper, the formulas for natural frequency and amplitude of the core standing wave vibration are derived. A comparison of test data taken on a 60 MVA generator with calculation results shows that the natural frequencies obtained are close to those measured. Discrepancies are, however, found between...

The stator core resonance of hydro-electric generator caused by negative-phase-sequence current is a new problem encountered in recent years in this country, and to our knowledge, scarcely known abroad. In this paper, the formulas for natural frequency and amplitude of the core standing wave vibration are derived. A comparison of test data taken on a 60 MVA generator with calculation results shows that the natural frequencies obtained are close to those measured. Discrepancies are, however, found between the calculated amplitudes and the measured ones, particularly at low I2%, yet at higher I2(74%), the discrepancies are shown to be within reasonable limits.

本文从理论上分析由负序电流引起的定子铁心振动.推导了固有频率和振幅的计算公式.文中介绍了水电站试验实测的部分结果,将计算值与实测值相比较,可见固有频率的计算值比较接近实测值,可作为设计电机的依据;振幅的计算值与实测值相差较大,但仍有一定的准确性,可供工程计算作参考.

Vibrating optical fiber will bend and be deformed. Theoretically bend and deformation increase transmission losses in the fiber. This paper analyses two kinds of additional attenuations when the fiber is in the condition of typical standing wave vibration.Through numerical calculation and experiments, conelution is made that these additional attenuations are quite small, which can therefore be neglected, in the first approximation.

光纤振动时必然导致光纤的弯曲和形变。从理论上讲,弯曲和形变都会增大光纤的传输损耗。本文分析了光纤在典型的驻波振动状态下,由这两种因素产生的附加衰减,通过数值计算和实验结果,得出了这种附加衰减是相当微弱的结论。因而在实际传输的条件下,光纤振动引起的附加衰减完全可以忽略。

Firstly this paper gains the formulas of the energy and energy stream ofstanding-wave in a string,and explains when the energy transfer of standingwave goesand comes between node and antinode,that the cycle of the eiiergy vibration is half as muchas the cycle of standing-wave vibration in a string.Secondly,with the aid of the figures itwas explained that when the amptilude of the vibration was the mi11imum,the energy wasgot together near antinode.Lastly,it was...

首先得出了弦驻波的能量公式和能流公式,从而说明驻波的能量在相邻波节与波腹之间来回传输,其能量振动的周期为驻波振动周期的一半。进一步用作图法说明,当振动达到最大时能量储存在波节附近;当振动经过平衡位置时,能量储存在波腹附近。最后指出实际的弦驻波实验是有能量传递的。
