Development of Computer Simulation System for Overhauling of Hydroelectric Generating Unit

In order to make the reasonable and effective technical schemes for overhauling and solve difficulties in training overhauling workers in hydroelectric power plants, a computer simulation system for overhauling of a hydroelectric generating unit was developed by combining computer-aided simulation, virtual reality and multimedia techniques. The key techniques in this system include 3-dimensional digital modeling for all the parts of a hydroelectric generating unit, knowledge database setting up for overhauling technique and precess, implementation of 3-dimesnsional visualization, and dynamic simulation of assembling processes based on the virtual reality and multimedia techniques. This system has been successfully used in the overhauling of a large hydroelectric generating unit and the training of overhauling workers.
