电力系统各元件的序阻抗分析计算

Analysis and Calculation of Sequence Impedance of Power System Components

电力系统中的短路故障大多数是不对称的,一般计算都是采用的对称分量法。通过这一方法的使用,其与计算系统不堆成短路的时候,其选择使用的参数也就是电力系统元件所对应的相序参数。所以序阻抗的分析和计算是短路计算的基础,显得尤为重要,特别是零序阻抗的分析和计算。

Most of the short circuit faults in power system are unsymmetrical.Generally,the symmetrical component method is used.Through the use of this method,when it does not stack short circuit with the calculation system,the selected parameters are the phase sequence parameters corresponding to the power system components.Therefore,the analysis and calculation of sequence impedance is the basis of short circuit calculation,which is particularly important,especially the analysis and calculation of zero sequence impedance.
