摘要
电力系统中的三相不对称问题给对称分量法的应用带来了困难。使用相分量方法在分析电力系统三相不对称网络时更加方便。由于传统相分量法不能充分利用电力系统对称元件可解耦的特性,计算量较大,影响了广泛应用。基于相分量模型提出的多态相分量法,可以处理电力系统各种不对称的问题;使用矩阵和向量作为计算元素,实现了三相计算和单相计算的统一;通过多态化矩阵变换,减少了计算量,实现了与对称分量法相同的计算效率。
The three-phase unbalance problems in power system make it difficult to apply symmetrical components. Phase components method may offer advantages in the analysis of unbalanced three-phase networks. In despite of the attribution that symmetrical components in power system can be decoupled, phase components method has too large calculation to apply widely. Based on phase co-ordinate representation, the polymorphic phase components can be used to deal with all kinds of unbalance problem. The unification of three-phase and single-phase calculations is realized with polymorphic matrices and vectors calculation. Calculation is reduced by polymorphic matrix translation and is similar as symmetrical-component quantities.
