Main transformer displacement strategy making method based on major emergency defect rate

Abstract

The invention discloses a main transformer displacement strategy making method based on the major emergency defect rate. The method includes acquiring the key attribute data of all main transformers as the research object; calculating the major emergency defect rate of each main transformer in each operating year, performing regression analysis on the major emergency defect rate and the operating years of each main transformer, establishing a regression model of the major emergency defect rate and the operating years, and determining the model parameters by means of a least square theory; establishing a target function and a constrained condition based on the main transformer damaged degree reduction degree / displacement cost maximization principle; and obtaining the main transformer displacement strategy through the adoption of an implicit enumeration method to solve the target function. The method guarantees the main transformer risk in an acceptable range, acquires the high fund utilization efficiency, and effectively assists power grid enterprises to develop investment decisions through the establishment of the predicted model of the main transformer major emergency defect rate and based on the optimal manner of equipment damaged reduction degree cost ratio.

Description

technical field [0001] The invention relates to a method for formulating a main transformer replacement strategy, in particular to a method for making a main transformer replacement strategy based on a major emergency defect rate. Background technique [0002] With the advancement of power grid information construction, a large amount of data has been generated in the process of power grid production and operation. These data contain many laws and characteristics closely related to safety production and equipment management. Using technical means to analyze and mine these data, we can get Useful data can assist enterprises to grasp the inherent characteristics of power grid production and operation, master management rules, refine business models, assist management decision-making, and develop management innovations, thereby improving the lean management level of enterprises and promoting enterprise management from extensive to intensive. , Refined transformation. [0003] ...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing equipment replacement strategy formulation methods only consider the degree of equipment degradation, but do not consider the impact of equipment replacement on the overall risk of the power grid. At the same time, they do not consider the overall capital utilization efficiency.
