Research of 3-D digital simulation platform for TGP and Gezhouba cascade dispatching

This paper researches the key points of TGP(Three Gorges Project) and Gezhouba's 3-D simulation system,describes exactly the database established process and the 3-D visualization project frame.The system stuies the data interface among TGP real-time database and the dispatching mathematical model,displays the dispatching methods in 3-D scene intuitively,consequently actualizes the querying and sort displaying of the shipping related data.A new platform is provided in this paper for cascade dispatching decision-making.
