Problems solved by technology

[0005] The current investment decision-making plan for primary equipment overhaul and technical transformation of the power grid is determined based on historical experience. There is no quantitative and accurate evaluation method, and the required investment decision-making plan for technical transformation cannot be accurately formed.
[0006] In addition, there is currently a lack of a cost data accumulation and display platform for the entire life cycle of various equipment after technical renovation and overhaul, and the relevant data of the entire process cannot be displayed, which is not conducive to subsequent analysis

Abstract

The invention provides an online construction method for an overhaul technical improvement scheme of primary equipment of a power grid. The method comprises the following steps: obtaining equipment annual operation and maintenance data of the same type and different operation years of equipment of the same manufacturer of the primary equipment of the power grid online; establishing a cost prediction model of the power grid primary equipment under the limited data volume based on the operation and maintenance data; based on the predicted future cost of the equipment, determining the economic life of the equipment by taking the lowest annual average cost of the primary equipment of the power grid as a target; determining a technical improvement scheme or an overhaul scheme according to the current running age limit of the equipment and the obtained relationship between the economic life limit and the technical life limit of the equipment; and visually displaying the online formed technical improvement scheme or overhaul scheme.

Description

technical field [0001] The disclosure belongs to the technical field of power grid primary equipment, and in particular relates to an online construction method and system for an overhaul technical transformation plan of a power grid primary equipment. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] At present, with the gradual deepening of the reform of power grid assets and the reform of transmission and distribution prices, the management of power grid assets is becoming more and more lean, gradually shifting from extensive to precise investment and maximizing equipment utilization. [0004] How to maximize the benefit of equipment through the investment decision-making of a power grid equipment overhaul technical transformation, which can not only meet the maximum economic effect in the entire life cycle of the equipment, but also ens...
