The modular modeling idea is applied to the simulation of the transition process of the host system of the hydropower station. The logarithmic curve projection method is used to describe the characteristics of the runner and the zero flow state method is used to calculate the initial steady state of the system. Under the premise of compressibility of fluid, this paper solves the problem of on-line continuous solution of time-varying system of auxiliary pipe network in hydropower station. At the VCS3 platform, a full-computer simulation system of hydropower station with flexible configuration is established. At present, satisfactory results have been obtained, It laid the foundation for the future configuration of simulation calculation of different power plants.
