The invention discloses an experiential interaction process design method for ultra-high voltage power virtual training. The method comprises the steps that overall logic design of the interaction process of an ultra-high voltage virtual training system is completed; overall modeling of the interaction process of the system is completed, and function module division of the system is established; and a task-driven management module, a data model management module and an interaction process control module are designed. According to the invention, under the background of an immersive virtual reality technology, user experience design is taken as the basic starting point, optimization design modeling is carried out on the interaction process of the virtual training system of an ultra-high voltage substation; the interaction process of the system is effectively controlled; experiential interaction between a user and the system is realized; and the training learning experience of the user isenhanced.
