Description: 求解大型对称或非对称方程组，采用稀疏矩阵存储及求解算法，在电力系统仿真分析软件中得到应用-Sparse1.3 is a flexible package of subroutines written in C used to
quickly and accurately solve large sparse systems of linear equations. The
package is able to handle arbitrary real and complex square matrix equa-
tions. Besides being able to solve linear systems, it is also able to
quickly solve transposed systems, find determinants, and estimate errors
due to ill-conditioning in the system of equations and instability in the
computations. Sparse also provides a test program that is able read matrix
equations from a file, solve them, and print useful information about the
equation and its solution.
Sparse1.3 is generally as fast or faster than other popular sparse
matrix packages when solving many matrices of similar structure. Sparse
does not require or assume symmetry and is able to perform numerical pivot-
ing to avoid unnecessary error in the solution. It handles its own memory
allocation, which allows the user to forgo the hass Platform: |

Description: 电力系统潮流计算体现在数学就上是多元非线性方程组的求解问题，求解的方法有很多种。牛顿—拉夫逊法是数学上解非线性方程式的有效方法，收敛性好、迭代次数少。将牛顿—拉夫逊法用于潮流计算是以导纳矩阵为基础的，由于利用了导纳矩阵的对称性、稀疏性及节点编号顺序优化等技巧，使牛顿—拉夫逊法解题规模和计算速度进一步提高，此算法至今仍是潮流计算中广泛采用的优秀算法。(Power flow calculation in power system is a problem of solving multivariate non-linear equations in mathematics. There are many methods to solve it. Newton-Raphson method is an effective method for solving nonlinear equations in mathematics. It has good convergence and fewer iterations. The application of Newton-Raphson method to power flow calculation is based on admittance matrix. Because of the use of symmetry, sparsity and optimization of node number sequence of admittance matrix, the scale and speed of Newton-Raphson method are further improved. So far, this algorithm is still an excellent one widely used in power flow calculation.) Platform: |
