Abstract

The invention discloses a power transmission line ice-melting decision method based on a shortest path algorithm and 0 / 1 decision. The method comprises the following steps: 1) dividing an icing line area; 2) calculating ice-melting time of each team for a single icing line; 3) calculating required time from each team to each substation of the icing area; 4) calculating required time from one substation to another substation in the same icing area of each team; 5) calculating the shortest ice-melting time of each team in all icing lines of the icing area; 6) establishing a power transmission line shortest ice-melting time decision-making model; and 7) calculating the shortest ice-melting time and outputting an ice-melting decision scheme. The power transmission line ice-melting decision method can quickly and effectively make a full-network icing line decision-making method, so that ice-melting time is reduced, and operability is high; and the problems that a power transmission line ice-melting decision is mainly made by human experience, and the decision-making time is long and risk of decision making is large under the conditions of multi-lines and complex working condition are solved.

Description

technical field

[0001] The invention belongs to the technical field of power transmission and distribution, and in particular relates to a decision-making method for melting ice of a power transmission line based on a shortest path algorithm and 0 / 1 decision-making. Background technique

[0002] Ice disasters occur frequently in southern my country, which often lead to the collapse and disconnection of power transmission lines due to icing, causing large-scale power outages in the power grid, seriously threatening the safety of the power grid, affecting people's production and life, and causing huge losses to the country. For example, the power grid ice disaster in 2008 caused the collapse of more than 1,300 bases of 220kv and above transmission lines of the State Grid Corporation of China, damage to more than 100 sets of 220kv and above substation equipment, and direct property losses of more than 10 billion yuan. Power grid ice disaster prevention is a complex system engin...
