| 摘 要： | 作为计算输电网可用输电能力的一种重要方法,连续潮流法一直受到电力工作者的关注.文章在分析基于P-Q解耦潮流的ATC模型基础上,给出了ATC计算中预测和校正的详细算法.这种算法在迭代过程中以不变的系数矩阵和代替变化的雅克比矩阵B′和B＂,可以节省存储空间、提高计算速度.以IEEE14节点系统为例,文章分别运用基于P-Q解耦和牛顿-拉夫逊法的连续潮流法进行ATC计算,进一步验证了基于P-Q解耦法ATC计算方法的有效性.

| Abstract: | As an important method of computing Available Transfer Capability in transmission network, the continuation power flow is always favored by electric operators. Based on the ATC model of P-Q decomposition, the method of predictor-corrector during computation of ATC is presented. In the iterative, the constant matrixB'and B" take the place of variable Jacobian matrix. It can reduce the requirements of storage capacity. The computation speed can be improved. The proposed method is applied to the IEEE14 bus system. Compared to the method based on Newton-Raphson, the result proves that the proposed method is valid. |
