Method for managing primitive of automatization system based on dynamically loading and plug-in unit technique

The invention discloses a dynamic management technology for drawing packet, object of model management and the graphic element thereof in power automation system software, in particular to a novel object management and expansion method realized by utilizing the dynamic loading and plug-in technology, which comprises graphic primitive drawing, model building, validity check, and the like, thereby ensuring flexibility and scalability. The invention provides a technical means which can expand and refit model equipment without recompilation and maintenance, thereby facilitating demand adjustment and expansion of new application, simultaneously, ensuring the uninterrupted operation of the system and meeting the demand for development of the power automation system. Additionally, the technologycan be applied to other monitoring systems.
