1、水能计算水能计算步骤：1）得到流域的水文资料，对其进行整理，最终得到水能计算成果表中的（2）（3）（5）（6）（7）（8）；2）用（2）列19年累计天数除以19得到年平均天数（4）列所示；3）由公式H=Hg-h损，即表中（6）列压力前池水位减去（7）列下游尾水位高再减去（8）列水头损失得到（9）列净水头高；4）由公式N=KQH得到（10）列的装机容量，即用（2）列的日平均流量乘（9）列净水头高再乘以出力系数K,本设计中是引水式小型水电站，所以本出K选8.2；5）用表中（10）列装机容量上下两行差得到（11）列出力差；6）由公式E=NT得到（12）列电量差，即用（1

2、1）列出力差乘以（4）年平均天数；7）由（12）列的电量差累计可以得到（13）列的年累计发电量；8）由（3）列年平均天数乘以24可以得到（14）列装机利用小时数。由以上8个步骤可以得到下表中的水能计算成果表。由（10）列装机容量和（14）列装机利用小时数画得下图装机利用小时数：图一装机利用小时数水能计算成果表序号日平均流量m319年累计天数年平均天数频率压力前池水位m尾水位高m水头损失m净水头m装机容量kw出力差kw电量差万kw.h年累计电量万kw.h装机年利用小时数h（1）（2）（3）（4）（5）（6）（7）（8）（9）（10）（11）（12）（13）（14）1
