水轮发电机的风路和数值解法

Numerical calculation of ventilation circuit for water-wheel generator

对水轮发电机的典型通风系统结构进行了分析，绘出相应的等效风路图。并根据等效风路图列出压力平衡方程和流量守恒方程。采用高斯消去法和欠松弛迭代法并应用计算机对这些方程进行数值求解，从而计算出各支路的流量。

In this paper, the ventilation system of water- wheel generator is analyzed, the equivalent ventilation circuit is drawn. According to the equivalent ventilation circuit, the equations of pressure and air now are obtained. The equations are solved numerically using the method of Gauss elimination and under-relaxation iteration by computor, thus the air flows in every branch are determined.
