Abstract

The invention discloses a TRIZ-based guidance method for the condition maintenance of substation equipment, including the steps of establishing a guidance model for the condition maintenance of the substation equipment: setting the TRIZ invention principle matrix, and collecting various state quantities of the condition maintenance of the substation equipment to be guided Each parameter in the empirical value sequence of the TRIZ invention principle domain, obtain the mapped discrete sequence value of the state quantity reconstruction, obtain the complete correlation coefficient between the state quantity and the TRIZ invention principle, and construct the guidance model of the substation equipment; and use variable The steps of the electric equipment guidance model to guide the substation equipment: collect the parameters of various state quantities of the condition-based maintenance of the substation equipment to be guided and the actual sequence of the principle domain of the TRIZ invention, and obtain the actual mapping discrete sequence of the reconstruction of the state quantity Value, obtain the complete correlation coefficient between the state quantity and the TRIZ invention principle and obtain the guidance result of the substation equipment. The invention improves the accuracy of regular evaluation results of the working states of No. 1 and No. 2 substation equipment of the 220KV substation of the power grid.

Description

technical field [0001] The invention relates to the field of maintenance of substation equipment in a power system, in particular to a TRIZ-based guidance method for state maintenance of substation equipment. Background technique [0002] The condition-based maintenance of substation equipment is a major change in the maintenance method of power equipment, and it is a production management method vigorously advocated by power grid operating companies. The characteristic of condition-based maintenance is to perform on-demand maintenance according to the equipment status, avoid blindness, make the maintenance work more precise and scientific, and the maintenance effect is more significant. The power grid company has given the state-of-the-art maintenance guidelines for the substation equipment of the power grid, and these guidelines are widely used in a large number of substation equipment in China. The current maintenance guidelines are evaluated manually based on traditiona...
