Provided is a dynamic drawing presentation system based on interactive simulation operation. An electrical drawing is dynamically drawn using a simulation programming technology, and is displayed in ascene supporting interactive simulation operation. The system is used for demonstrating the action principle of an electrical drawing. A user can operate a simulated electrical component through thetouch screen or mouth click and change the state of the component. Meanwhile, the user can trigger preset fault information through the touch screen or mouth click and change the state of the relevantsimulated component. The other electrical components in the system will automatically judge the states thereof and make corresponding changes according to the changes, and thus, dynamic change of thewhole drawing is realized. The system is further equipped with functions such as fast search for related components, search for the action conditions of components, interactive analysis of typical failure cases, and on-site scene display, and is a set of electrical drawing principle dynamic demonstration system with high independence and strong interaction.
