Abstract:

传统机电波理论将实际电网建模为整个二维空间的连续体模型,将机电波处理为二维平面波。这与实际电力系统情况不完全相符,因此不能真实反映实际电网中机电波传播的特性及现象。为此提出一种全新的由一维均匀参数段按照电网拓扑关系构建的电网框架结构模型。首先分析了实际电网中机电波传播过程的特征,提出电网边界的无反射性、扰动传播距离与地理距离的非一致性以及电网介质的分层特性。在此基础上,将一维链式电网中发电机转动惯量作用域的概念推广到实际电网,提出沿传播路径逐级对称分布转动惯量的等效化处理方法,从而构建了具有分段均匀参数特征的电网空间框架结构模型。进一步采用状态传递矩阵证明了转动惯量等效处理方法的正确性。最后,在PSD-BPA软件中进行IEEE14节点系统仿真,验证了所建模型与实际电网模型的等效性。
