Self-adaption composite heating power ice melting cooperating method

Abstract

The invention discloses a self-adaption composite heating power ice melting cooperating method. A load transfer ice melting method, a direct-current ice melting method and a radiation absorption type coating ice melting method are adopted for self-adaption cooperation, and therefore the optimal ice melting effect is achieved. The method comprises the following steps that 1, primary configuration parameters of an ice melting cooperating scheme are determined; 2, distributing setting of the self-adaption ice melting method is carried out according to a trigger condition and the configuration parameters. According to the self-adaption ice melting cooperating method, the control range is expanded by dynamically adjusting the ice melting need judgment standard. The ice melting effects of various ice melting methods can be effectively utilized, waste is reduced, and the direct average ratio of an ice melting means is restrained.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering, and in particular relates to an adaptive coordination method of multiple ice-melting modes for transmission lines. Background technique [0002] In recent years, the number of icing disasters caused by transmission lines has increased, the scale has expanded, and the damage has increased, which has brought a huge impact on the normal operation of the power grid and people's living standards. [0003] In order to solve the problem of icing on transmission lines in winter, which seriously threatens the safe operation of power systems, a lot of research has been done on the problem of icing on transmission lines at home and abroad, and many methods of melting ice on transmission lines have been proposed. In the case of severe icing, the commonly used methods are mechanical deicing and thermal ice melting. The operation of mechanical deicing is cumbersome, and it is easy to dama...

Problems solved by technology

However, the structure of the controllable rectification device is relatively complicated; the harmonic content is high and the reactive power loss is large during operation, so it is necessary to configure an AC filter with a certain capacity for reactive power compensation and filtering; and it is necessary to configure responsive protection equipment, which requires a considerable investment

[0007] The radiation-absorbing paint melting method achieves the deicing effect by absorbing the heat of sunlight, and uses organic carbon black with Si0 2 Or use C and Al as emitters to improve spectral selectivity, and use organofluorine, organosilicon, alkanes, and olefins as substrates to achieve the purpose of increasing hydrophobicity, but they will gradually lose their effectiveness over time. Anti-icing Limited durability, needs to be repainted before ice and snow weather, time-consuming and labor-intensive, and the effect is not good

[0008] It can be seen that the load transfer deicing method, the DC current deicing method, and the radiation-absorbing coating deicing method have their own advantages and disadvantages.
