摘　　要：针对回路法解算与调节复杂风网流量不方便、收敛速度慢甚至假收敛等问题,提出利用通路调节复杂风网流量方法。在建立通路矩阵、各分支阻力列向量的基础上,列出通路风压方程,用节点邻接矩阵法寻找通路。以基本阻力路线上的风压和作为标准值,调节其他各通路阻力。将通路矩阵、各分支阻力列向量按余树弦在前、树枝边在后的顺序进行排列,通过求解线性方程组,得到各余树边阻力调节量。用该方法调节复杂风网流量时,便于找出关键路线和主导分支,运算速度快、精度高,调控方案选择更广泛。Proposed to use the path method adjusting the complex wind network, avoiding inconvenient,slower speed or even false convergence of loop method. Wind pressure equation of path is listed basises on the establishing path matrix and the branch resistance column vector, and the node adjacency matrix method is used to find the path. The wind pressure on the basic resistance route and the standard value are used to adjust the resistance of the other passages. The path matrix and the branch resistance column vectors are arranged in the order of the cosine chord in front and the branches in the back. The residual tree edge resistance adjustment amount is obtained by using the linear equations. This method is easy to find the key route and the dominant branch when is used to adjust the flow of complex wind network, the operation speed is fast, the precision is high, and the control scheme is more widely selected.
