The invention relates to the electric power system regulation and control informatization field and especially relates to a multidimensional analysis display system based on power grid regulation and control operation monitoring and a method thereof. The system comprises a display screen, a display theme module, a data model, ETL data integration, a three-area power grid dispatching operation management system (OMS) and a national power grid intelligent power grid dispatching technology support system basis platform (D5000). The display theme module comprises 10 theme modules of an operation mode, accident tripping, an equipment defect, back brake operation, alarm suppression, a reactive voltage, information processing, online monitoring, an operation and maintenance condition and a work condition. Information of each transformer station can be timely grasped, a supervisor can be reasonably arranged to carry out key work, a power grid operation state is monitored, and a power grid historical operation condition is analyzed and displayed so as to guarantee health operation of a power grid.
