For getting the runner characteristics more correctly, researching the representation of runner characteristics of the kaplan turbine in this paper, and using this method of modifying runner characteristics to calculate the transient of hydraulic power station. improving the calculating model of the axial thrust in the kaplan turbine ' s transient. base on the theory of screw propeller without any boundary, using the theory of screw propeller with pipe, and the formula to calculate the dynamic axial thrust during transient is developed
本文對轉槳機組在過渡過程中的槳葉劃水產生水推力的數學模型進行了改進，在原來使用無邊界螺旋槳進行等效的基礎上，使用了導管螺旋槳對轉槳機組中的槳葉劃水進行等效，並且比較詳細的分析了影響轉槳機組軸向水推力的各個因素，以及給出了動態計算軸向水推力的公式，通過計算表明，使用改進后的動態水推力計算模型得到的結果能較好的反應實測的動態軸向水推力。 -
The axial - flow turbine generator set is suitable for low head from 2m to 70. its feature is that the water flow passes through the runner axially. the axialflow turbine generator set can be classified into two forms according to the runner construction : one is fixed blades propeller for small variation of head and power, the other is movable blades kaplan for large variation of head and power
貫流式水輪發電機組是低水頭大流量電站的較好機型，一般適用於水頭2 ~ 15米，其特點是水流從進水口到尾水出口都是軸向的，流道基本上成直線，因而貫流式水輪發電機組具有水流特性好，效率較高等特點。
