Power grid section self-adaptive dynamic monitoring method

The invention belongs to the technical field of power grid dispatching control, and particularly relates to a power grid section self-adaptive dynamic monitoring method. Comprising the steps of 1, performing power grid stability limit self-adaptive dynamic monitoring based on a random matrix theory; 2, constructing a power grid section out-of-limit dynamic repository based on power grid stability regulations by monitoring real-time operation conditions of a section, power transmission and transformation equipment, a power plant, direct current and the like; step 3, configuring and monitoring flexible equipment combinations such as temporary sections, custom sections, custom combinations and the like, and performing custom combinations of power grid sections; step 4, flexibly combining the inherent section and the newly added self-defined section, and performing dynamic real-time refresh monitoring on the section by adding the limit value of each section; the working intensity of dispatchers is reduced, the te
