| Abstract: | The hydraulic transient calculation for rejecting load is carried out adopting explicit characteristics method. The maximum pressure taking place in spiral case and the unit maximum speed rise are given also. The principle of explicit characteristics method is transforming hydraulic dynamics equations and mass conservation equations into four total differential equations,and then resolving the equations. The explicit characteristics method is more accurate than traditional calculation method. |
