Every link of power system may exist security risks, power industry funds and technology is highly concentrated, the production equipment is very expensive, its operating parameters almost reached the extreme, physical simulation of its production process of experimental teaching costs are extremely high, resource consumption is huge, and may cause malignant environmental pollution. Teaching, training operations can not be carried out at will, therefore, the establishment of virtual simulation experiment center is an effective solution to the experimental teaching of electric power production subject group. Visualization technology makes simulation virtual teaching and training become a reality, through power generation process simulation, power network simulation, substation simulation, centralized control station simulation, power grid dispatching automation system simulation, through virtual reality technology to imitate the work done by means of electric power teaching and training has become a new development trend, the application effect is good.
