【Abstract】 In this paper,a method of Modular model building is applied in the transient simulation of host machine of hydropower station.The runner characteristic is described by Logarithmic curve projection method.The initial value of steady state is resolved by method of “condition of Zero delivery”.The sustained and on-line solution of time-varying auxiliary system of hydropower station is realized by method of “given head activate”.A computer-based simulation system of hydropower station that can implement flexible configuration has been set up on vcs3 and reasonable results have been achieved.This will benefit the configuration of simulation of different hydropower stations.更多还原
