In order to simulate the hydro dynamic characteristics of hydropower station conveniently and quickly, a new simulation method based on Flowmaster2 software is proposed. According to Flow-master2 software requirements, the mathematic model of the hydro-generator, the most critical component in the establishment of hydropower simulation system, is deduced. The steps and programming methods of establishing the simulation model are introduced in detail. Through modeling a Francis turbine, it shows that the method in this paper can realize the hydraulic system simulation modeling of hydropower station conveniently and quickly, which lays the necessary foundation for the digital simulation of large hydropower project.
