OCS monitoring attribute one-key checking tool for power grid line

The invention belongs to the technical field of power grids, and particularly relates to a power grid line OCS monitoring attribute one-key checking tool comprising a graph-model consistency checking module used for comparing graph parameters in a plant station with parameters in a database so as to screen out different point information; the line table updating and topological relation checking module is used for checking whether lines connecting the two plant stations exist in the two plant stations or not; and the tool setting module is used for setting parameters and project execution processes. The problems of large workload, long time and possible mistakes and omissions of new line monitoring attribute setting in a manual checking and dispatching automation system before closing and power transmission of a new line of a power grid are solved, and the correctness and completeness of line monitoring attribute setting are ensured. The working efficiency and the operation quality of automatic operation and
