Embodiment Construction

[0055] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, in the case of no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0056] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways than described here; obviously, the embodiments in the description are only some of the embodiments of the present disclosure, and Not all examples.

[0057] When the transmission line is heavily icing, it will lead to accidents such as downed towers and disconnected lines. Timely measures to melt ice on ice-covered transmission lines can effectively reduce the hazards of ice disasters. However, considering the principle of economy, it is imp...

Abstract

The invention relates to a power grid ice melting decision-making method and device, computer equipment and a medium, and the method comprises the steps: obtaining first icing risk parameters of M substations, obtaining N second icing risk parameters and N target icing risk parameters corresponding to each substation, and generating a target risk matrix according to the target icing risk parameter, obtaining a decision-making matrix according to the target risk matrix, the target function and the constraint condition, and allocating an ice melting device to the transformer substation accordingto the decision-making matrix. Because the target icing risk parameter represents the icing risk which can be reduced when the ice melting device is distributed to the transformer substation, the target function indicates that the total ice melting income is maximum, and the decision-making matrix obtained according to the target risk matrix, the target function and the constraint condition is the optimal ice melting decision-making scheme. Therefore, the ice melting equipment is allocated according to the decision matrix to melt ice for the transformer substation, the ice melting efficiencyis improved, and the risk of safe operation of a power grid is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of electrical engineering, and in particular to a decision-making method, device, computer equipment and media for power grid melting ice. Background technique [0002] In recent years, frequent natural disasters have seriously affected the safe operation and reliable power supply of the power grid. Among them, icing in winter is one of the common natural disasters in low-temperature, rainy, snowy and freezing weather. Severe icing of transmission lines will lead to accidents such as downed towers and broken lines. In order to reduce the hazards of ice disasters, it is the most direct and effective prevention and control method to take ice-melting measures for ice-covered transmission lines. [0003] When a large-scale ice disaster occurs in the power grid, due to the limitation of the number of ice-melting devices, it is impossible to carry out ice-melting work on all ice-covered transmission line...
