WEB BASED SCALABLE INTELLIGENT MULTIMEDIA VIRTUAL LABORATORY FOR POWER ENGINEERING Ning Gong Brian Butz Saroj Biswas Li Bai Department of Electrical and Computer Engineering Temple University, Philadelphia, PA19122 AbstractA laboratory practicum is considered a key component of engineering education. However ahands-on approach is often ignored for courses involving electrical machines because of safetyissues, expense, and lack of qualified teaching assistants. When the advantages of combiningcurrent internet and web-based technologies with educational purposes are considered, a web-based virtual power laboratory offers a possible, positive alternative to providing physicaltraining and learning materials.This paper presents the planning and development of a web based application that can simulate avirtual laboratory for electric machines. This virtual laboratory application is developed on auniversal web-based platform that can be accessed anywhere by most mobile devices andstandard computers. The planned architecture of the virtual laboratory consists of eight modules:1) a Core Concept Knowledge Base, 2) an Experiment Knowledge Base, 3) MathematicalTools, and 4) a Virtual Instrumentation Core that are interfaced with 5) the StudentInteraction Module through 6) a Multimedia Graphical User Interface Module. Thesemodules are managed and authenticated by 7) a Scalable User Management Module, whichwill be monitored by 8) an Intelligent Tutoring Module. The graphical user interface (GUI)enables students to simulate electrical machines under different operating conditions. The virtuallaboratory will be supervised by a virtual Intelligent Tutor that can track the students’ progress,monitor the students’ actions and answer questions from the students.As a proof of concept, nine virtual experiments have been developed for DC generators andmotors. Machine concepts are summarized using text, 2D and 3D graphics as well as multimediaanimation. The animated GUI plays an important role in this system as it enables students toreview and retain basic concepts and builds a bridge from the virtual to the real laboratory.Multimedia is incorporated in this project to provide convenient visual and aural guidance forstudents to better understand power generators and machines. Students will be guided andsupervised by an intelligent tutor to: learn basic concepts, answer pre-laboratory questions,practice in virtual experiments and compose laboratory reports.The virtual power laboratory provides schools and colleges, which do not have physicalequipment, with an alternative way to train student with experimental concepts of electricalmachines. This application can also be used by students as a safe test bed for gaining hands-onskills before encountering with any real power equipment. Moreover, various interfaces andmodules developed in this application have been evaluated and tested to be user friendly anduseful learning auxiliary tools, and can be used for developing intelligent virtual laboratories forother engineering courses.Key Words: Virtual Power Laboratory, Generator/Motor, Animation, Web Application,Intelligent Tutor, User Management.
