The invention discloses a simple method for structuring and filing a real-time running way of a power grid. The simple method comprises a first step of structuring a data template of the power grid based on a latest structure and latest parameters of the power grid, a second step of structuring a data interface communicating with an EMS (Enhanced Message Service) according to CIM/SVG (Common Information Model)/(Scalable Vector Graphics) so as to extract real-time data from the EMS, a third step of developing a real-time running way generation module, a fourth step of structuring an exact real-time database of the power grid, and a fifth step of building connection with BPA (Bonneville Power Administration) server through a BPA interface and establishing contact between an offline BPA and an online EMS to enable the BPA to share the real-time data of the EMS. The system developed by the method can exceed the EMS on the aspect of some functions, and is an expansion and extension of the EMS function. The system established based on the method can be shared by scheduling, planning, biotechnology, design and other relevant departments or professions, and can play greater benefits within a wider range.
