Embodiment 1

[0058] Such as figure 1 As shown, a method for analyzing factors affecting the life cycle cost of a power transformer includes the following specific steps:

[0059] Step 1: From the perspective of the system, the life cycle cost of power transformers is a complete and dynamically changing system. The core of the system is the cost of power transformers, which is composed of multiple factors. The cycle cost is divided into five subsystems: initial input cost, operation cost, maintenance cost, power outage loss cost and decommissioning cost, and its life cycle cost Y is calculated:

[0060] Y=C 1 +C 2 +C 3 +C 4 +C 5 (1)

[0061] Among them, Y represents the life cycle cost of the power transformer, C 1 represents the initial input cost, C 2 represents the running cost, C 3 Indicates the maintenance cost, C 4 Indicates the cost of power outage loss, C 5 Indicates decommissioning costs.

[0062] The initial input cost C 1 The calculation method is:

[0063] C 1 =C...

Abstract

The invention relates to a method for analyzing influence factors of the whole life cycle cost of a power transformer. The method comprises the following steps: establishing a mathematical model of the whole life cycle cost of the power transformer; according to the mathematical model of the whole life cycle cost of the power transformer, establishing a power transformer system dynamics model based on the whole life cycle cost of each influence factor; carrying out simulation operation on the power transformer system dynamic model to obtain a simulation value of the whole life cycle cost of the power transformer; adjusting the value of each influence factor, judging the influence of each influence factor on the whole life cycle cost of the power transformer, and determining the key influence factor. Starting from the system dynamics theory, the whole life cycle cost of the power transformer is calculated, the change process of the whole life cycle cost and the cost influence factors can be directly reflected by adjusting the values of the parameters, the influence of the whole life cycle cost on the total cost is further researched, the key cost influence factors are determined, and the method is good in practicability and worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of electric power construction planning, and in particular relates to a method for analyzing factors affecting the life cycle cost of a power transformer. Background technique [0002] Power transformers play an extremely important role in power transmission and energy conversion in the power system. They have the characteristics of large investment, complex operation and maintenance, and long service life. Their cost occupies a very important share in the investment of the entire power system. The life cycle cost (Life Cycle Cost) research and management of power transformers can bring significant economic benefits and is a powerful guarantee for the sustainable development of power systems. [0003] Most of the parameters in the power transformer life cycle cost model are based on future predictions and judgments, so there are various uncertain factors in the life cycle cost analysis. To determine the impa...
