摘要
为解决传统Scott-Hensley网络解算算法在寻找回路过程中速度过慢从而导致解算时间过长的问题,本文基于节点压能算法进行相应研究,对节点压能算法的迭代原理进行分析,从数学角度确定其在实际应用中的可行性,推导节点压能解算法的数学模型,给出了通风网络中各个节点的压能校正迭代式以及算法流程;并针对节点校正式中存在不收敛和收敛慢的问题,根据通风机特性曲线的不同拟合次数给出相应的解决方法。最终通过示例证明了在同一复杂通风网络中相较于Scott-Hensley算法,节点压能算法具有收敛速度快的特点,且收敛误差同Scott-Hensley算法相比差别不大。
According to finding ventilation loops,traditional Scott-Hensley network solution algorithm is so slow to require more solution time.To solve this problem,this paper carries out corresponding research and analyzes the iterative principle of the node pressure energy algorithm.From a mathematical point of view,this paper determines the feasibility of this algorithmin practical application and deduces the mathematical model,which gets pressure energy correction iterative formula and algorithm flow of each node in ventilation network.Aiming at the problems of non convergence and slow convergence in node calibration formal,the corresponding solutions are given according to the different fitting times of fan characteristic curve.An example shows that in the same complex ventilation network,the node pressure energy algorithm can achieve fast convergence and similar convergence error compared with Scott-Hensley algorithm.
