Simulation And Training System Platform On Computer Based On Virtual Reality For Substation

The personal ability of substation operator is one of the most important factors that affect the security and reliability of electric power system.So, the substation operator should be trained before he/she starts to operate real equipment. At present, many simulation training systems for substation have been developed and effectively used.However, most of these systems are developed for a certain substation, so their generality, expansibility and maintainability are not very satisfying. Moreover, the training interface are almost all two-dimensional windows, and the reality is poor.Contraposing the shortcomings of these two aspect, the simulation training system based on virtual reality for substaion is introduced in this paper.First, the Object-Oriented Design is applied for analyzing the substation system. According to data requirement of the system, the relation database system is used to describe the data information. And indoor secondary equipment editor platform, the acident phenomena and condition editor platform, the relation define platform and the simulation training module are developed basing on the information of the database. These platforms are used to change the equipment information of the substation and wirte to the database. The simulation training module is used to read the information from the database and reconstruct the substation, including the equipments and the relation between them. So the generality of the system is achieved.Second, virtual reality is introduced in this paper. OpenGL(Open Graphics Library) and 3D Studio Max are used to construct the three-dimensional environment of the substation. Using the vivid model of real device instead of button and label, the reality of simulation training interface is greatly improved.Meanwhile, the operation of the virtual equipment is implemented by using the the interactive function of OpenGL. And the result of operation is showed in the virtual scene. The student could learn the experience more directly and vividly, and the result of training is more effective.The system developed in this paper is provided with the facility and maintainability of software simulation. Also, the generality is achieved and the reality is greatly improved. So this system could be widely applied.
