输电线路在参数不对称时，传统的分析方法如对称分量法失效，此时需要采用模分量方法，此方法的核心在于求解相模变换矩阵。为求解该相模变换矩阵，从标准 Clarke变换矩阵出发，通过矩阵变换，得到适用于不对称线路模分量分析的相模变换矩阵，即改进的 Clarke 变换矩阵。将上述矩阵应用于不对称输电线路的模分析，可以有效减少计算量。仿真结果验证了该方法的可行性。

Traditional symmetrical component method becomes invalid under asymmetrical parameters of transmission lines and in the case the modal analysis has to be used, and the core of the modal analysis is to solve the phase-mode transformation matrix. Starting from standard Clarke transformation matrix and through matrix transformation, the phase-mode transformation matrix suitable to the modal component analysis of asymmetrical transmission line, i.e., the improved Clarke matrix, is obtained. Applying the obtained matrix to modal analysis on asymmetrical transmission line the calculated amount can be effectively reduces. The feasibility of the proposed method is verified by simulation results.
