| 摘 要： | 电力系统中,非线性电感元件与系统中电容串联可能产生次谐波谐振,对电力系统安全运行构成危害。电容式电压互感器(CVT)内部结构满足产生谐振的条件,有可能产生奇次谐波的稳定振荡。本文应用双描述函数方法对电容式电压互感器中的次谐波谐振域作了分析,并讨论了参数对形成次谐波谐振的影响及对次谐波谐振的抑制。

| Abstract: | In the power system,the subharmonic oscilation can be caused by the series connection of induc- tance elements with the capacitors.It is harmful to the save operation of the power system.If the inter- nal structure of capacitence-type voltage transformer.Meet the condition for producing harmonic os- cilation,a steady vibration of odd-order subharmonic oscilation may occur.Using the method of dual- input describing function,this paper analyses the region of subhormonic in the capatence type valtage transformer.And the parameters affecting the formation of the subharmonic cscilation and how to restrain it are also discussed. |
