提出了一种新算法能够得到依频率连续变化的转换矩阵,先使用传统算法计算出每个频率点的转换矩阵,然后通过一个平滑算法消除转换矩阵中由传统算法产生的突变点。通过一个双回三相不换相输电线路的算例将新算法与Newton-Raphson算法进行比较,实验结果和理论分析表明,新算法具有更高的效率和更好的追踪能力,且更加灵活,可以适应更多约束条件,实验表明可以通过改进约束得到光滑性更好的转换矩阵。
A new algorithm is proposed to get the transformation matrix with continuous frequency changes. The transformation matrix of each frequency point is first calculated by the traditional algorithm. Then, a smoothing algorithm is used to eliminate the mutation points of the transformation matrix generated by the traditional algorithm. The new algorithm is compared with Newton-Raphson algorithm through an example of double-return three-phase non-commutated transmission line. The experimental results and theoretical analysis show that the new algorithm has higher efficiency and better tracking ability and is more flexible, Can adapt to more constraints, experiments show that we can improve the smoothness of the transition matrix better conversion matrix.
