Firstly, the numerical calculation of hydraulic transients is made. The multiple time increment method that is applied to deal with the conjunction boundary of open-channel flow and pressure flow is given. The mathematical model of the whole diversion and power system is made to analyze the variation process of the open-channel flow depth, the surge chamber oscillation and the units operation parameter in all control working conditions. The minor oscillation stability of cascade hydropower stations is studied. The numerical calculation results verify preliminarily the feasibility of such design, at the same time show that it is aneffective measure to set up overflow section in the open channel in order to ensure the stability operation of units and it is necessary to monitor the open-channel flow depth in order to ensure the diversion discharge of the lower station is less than the outflow discharge of the upper station.
