十字复数链表在机电暂态仿真程序中的应用

Application of Cross Complex Linked List in Electromechanical Transient Simulation Program

随着电网规模不断扩大,计算节点日益增加,机电暂态仿真程序需要具备更高的计算速度和占用更少的内存空间。应用十字复数链表实现了矩阵元素的快速存取,避免数组元素的搬移,有效地提高了计算速度并减少了内存需求;同时避免了求解复数方程组时将实部和虚部分开求解,使复数网络方程组求解时像实数方程组一样方便;还实现了部分标准BPA数据的转换,经与中国版BPA仿真曲线的对比,证明了所开发的机电暂态仿真程序的正确性。

With the continuous expansion of power network scale and increasing of computational nodes, it is necessary for eleetromechanical transient simulation program to possess higher computing speed and take up less memory space. Cross complex linked list is used in this article,which can not only realize the fast access of matrix elements,bus also avoid the removal of array element,effectively improve computing speed and reduce memory requirements. At the same time, because the real part and imaginary part of a complex is not separated with each other when solving the complex equations, it is easy to solve the real equations. This article also completes the conversion of standard BPA data. Compared the curves with Chinese version of BPA＇s simulation curve,the correctness of electromechanical transient simulation program is proved.
