摘要:
为了缩减大规模电力系统小干扰稳定性分析的计算时间,对状态空间矩阵的快速形成方法进行研究。针对插入式建模技术,分析状态矩阵的形成过程;采用含双重阈值的不完全LU分解法(ILUTP),调整相关矩阵中非零元素的位置,将矩阵转换为对角占优形式;运用双共轭梯度稳定法(BICGSTAB),对处理后的大型稀疏矩阵迭代求解;矩阵的存储方式为行压缩稀疏存储;利用ILUTP与BICGSTAB的算法特性,实现了基于Open MP技术的并行计算;通过两个实际算例验证了所提方法的可行性及有效性。结果表明,该方法能够加快大型电力系统状态空间的形成过程。
Abstract:
In order to reduce the calculation time of small signal stability analysis of large-scale power systems, a method for quickly forming the state matrix is studied. For the plug-in modeling technology, analyze the formation of the state matrix Using incomplete LU decomposition technology (ILUTP) containing a double threshold correlation matrix adjusting the position of non-zero elements, the transformation matrix is a diagonal dominant matrix Iteratively solves the processed large sparse matrix using the bi-conjugate stabilization method (BICGSTAB)Matrix is stored as row-compressed sparse storage Using an algorithm with properties ILUTP and BICGSTAB achieve a parallel computing Open MP Technology Finally, the feasibility and effectiveness of the proposed method are verified by two real examples. The results show that this method can speed up the formation process of the state space of large power systems.
