Relay main power system automatic safety device , its normal running and working correctly , to ensure the security of the power system , stable, reliable and economic operation are essential . Power system relay protection device running reliability in addition , configuration and manufacturing quality , and other factors related to the principle of the device , but also with the design, installation , commissioning , tuning , operation and management of the device principle , wiring , tuning principle content mastery , and debugging methods , as well as operation and maintenance and management level are closely related. Therefore, the strengthening of technical training on the relay protection of employees , protection devices to improve the level of operation and maintenance , and help to improve the power system operation , security , stability , reliability , and economy . With the development of computer technology , multimedia technology, more and more widely , it is an important application areas - computer-aided instruction (Computer Assisted Instruction referred CAI) is increasingly favored by the education sector . The relay is a strong theoretical and technical disciplines, covering a wide range of knowledge points , comprehensive and strong tradition of teaching , training mode image is poor , difficult to fully expressed in the complex principles and processes . To compensate for the deficiencies of the existing training tools enable learners through multimedia rich performance practices , accurate image to learning the professional and technical knowledge to master the basic skills of the operation and maintenance of relay protection , the paper combined with my school and NARI relay the company 's collaborative research projects , development and design of the RCS-985 generator transformer composed of sets of protective devices multimedia training software . The software the computer multimedia technology and the relay protection training courses organic content including NARI-RELAYS introduction , product descriptions, device introduced to protect the principle , commissioning and operation and maintenance , and protection action demo . The software protection the principle logic diagram , protection device picture scanning technology and image processing software Photoshop processing , real video clip courseware is inserted by the non-linear editing system , the animation using Flash technology, making the relevant sections . Interactively on the chapter page and scroll through the directory tree combined to facilitate the use of the learners .
