Abstract

The embodiment of the invention provides a prediction method for a power grid and a controller. The prediction method for the power grid comprises the following steps: acquiring topographic data and meteorological prediction data of a to-be-predicted region; establishing initial field structure data according to the topographic data and the meteorological prediction data; and determining power grid galloping hidden danger points of the to-be-predicted region and an extension path between the power grid galloping hidden danger points according to the initial field structure data and an optimized ant colony algorithm. According to the embodiment of the invention, meteorological and topographic data features can be analyzed quickly, efficiently and comprehensively, the power grid galloping hidden danger points can be positioned finely, the extension path between the power grid galloping hidden danger points can be predicted accurately, the operability is high, the practicability is high, and the anti-freezing and ice-melting work of the power grid can be guided.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a prediction method and a controller for a power grid. Background technique [0002] The galloping of transmission lines is a relatively common but extremely threatening power grid disaster, which can cause damage to hardware, tripping of lines, or disconnection of towers, which seriously threatens the safe and reliable power supply in winter. Although galloping occurs in an ice-covered environment, the conditions for galloping disasters are more complex, not only requiring the thickness of ice-covering and the value of horizontal wind speed to be within a certain range, but also the locations of disasters are more dispersed, and the difficulty of protection is significantly increased. In order to strengthen the pertinence of galloping disaster protection, grid galloping prediction technology, especially the prediction of disaster occurrence and evolution character...
