A new core vibration calculation method of UHV shunt reactors is proposed to deal with the problem that vibration parameters of the core of an ultra-high voltage (UHV) shunt reactor cannot be measured on site. A series of tests have validated that the method can calculate the vibration parameters of a UHV shunt reactor core with different voltage ratios. The method is adopted to study the influence of nodal voltage fluctuations of the UHV AC tie line on the core vibration characteristics of a UHV shunt reactor under normal and abnormal operating conditions. The conclusion is drawn as follows: in the three operating states assessed herein, no matter whether the power grid is in a normal state or not, the core of the UHV shunt reactor will not reach magnetic saturation, and the vibration parameters of the reactor always maintain a linear relationship with the operating voltage. The changes of power grid operation parameters are introduced to the research into reactor vibration, which is conducive to a more comprehensive understanding of the actual operating state of a UHV shunt reactor. It can also provide help for the design and operation of UHV shunt reactors.

电压波动对特高压并联电抗器堆芯振动的影响
针对超高压并联电抗器堆芯振动参数无法现场测量的问题,提出了一种新的特高压并联电抗器堆芯振动计算方法。一系列测试证明,该方法可以计算出不同电压比的特高压并联电抗器堆芯的振动参数。该方法用于研究特高压交流联络线的节点电压波动对特高压并联电抗器在正常和异常工况下的核心振动特性的影响。结论如下:在本文评估的三个运行状态下,无论电网是否处于正常状态,UHV并联电抗器的堆芯都不会达到磁饱和,电抗器的振动参数始终与工作电压保持线性关系。电网运行参数的变化被引入到反应堆振动的研究中,有利于更全面地了解特高压并联电抗器的实际运行状态。它还可以为特高压并联电抗器的设计和运行提供帮助。
