The filling, review, execution and archiving management of two orders (operation order and work order) is one of the core businesses of on-site operation management of electric power enterprises. At present, the power grid management platform has developed the process and functions of two-order management and put them into application. However, from the perspective of the application status and analysis, there are still some problems that need to be solved urgently, such as lack of some core operation scenarios and incomplete two-order application functions. The intelligent two-order system effectively solves the current management situation of many non-standard and unqualified two orders, for instance, low efficiency of manual filling out operation orders and manual review by substation duty personnel, formalistic on-site safety investigation and safety technical disclosure of work orders for substations, and inconsistent writing requirements, thereby achieving the goal of effectively controlling the entire process risk of substation two-order management business from a three-dimensional, source-oriented, and transparent perspective.
