Embodiment 1

[0042] This embodiment provides a method for evaluating substation energy efficiency, such as figure 1 As shown, the method includes the following steps:

[0043] S1: Collect the basic data of energy efficiency indicators, establish an initial data indicator system, and perform dimensionless processing on the basic data of energy efficiency indicators;

[0044] Since the basic data of the energy efficiency index may be greater than 1, it is necessary to uniformly carry out dimensionless processing and unify the index. Easy to calculate. The obtained value after dimensionless processing can be used for correlation coefficient calculation.

[0045] S2: Calculate the correlation coefficient of the evaluated object according to the basic data of the energy efficiency index;

[0046] S3: Use the combination of AHP and expert scoring method to obtain the weight of each indicator;

[0047] Among them, the construction of the judgment matrix is ​​an important step in the AHP, whic...

Abstract

The invention provides a transformer substation energy efficiency evaluation method, which comprises the following steps of: firstly, finely analyzing various factors influencing the energy efficiencyof a transformer substation, obtaining the weight of each index by adopting a method of combining an analytic hierarchy process and an expert scoring method, and constructing an expert scoring weightsystem; meanwhile, in order to avoid the contingency of data results, different substations are investigated and researched, the initial data indexes of each substation are analyzed by accessing workers in the substations, a complete initial data index system is established, and then subsequent analysis is facilitated through data standardization; and finally, calculating the correlation coefficient and the weighted correlation degree to obtain the comprehensive energy efficiency evaluation index of each transformer substation, and simply evaluating the energy efficiency level of the investigated transformer substation by comparing the values to obtain the final energy efficiency levels of specific different transformer substations. According to the method, the energy efficiency analysisand evaluation of the transformer substation are simpler and more accurate.

Description

technical field [0001] The invention relates to the field of energy-saving analysis and evaluation of substations, and more specifically relates to a method for evaluating substation energy efficiency. Background technique [0002] In terms of energy-saving analysis and evaluation of substations, foreign scholars pay more attention to the innovation and invention of substation components or energy-saving transformation, energy-saving planning and layout, personnel and equipment management, etc., and pay attention to the overall energy-saving design and energy-saving transformation of substations. However, the impact on the energy efficiency of substation components Factors have not been specifically analyzed, and the research on energy efficiency of substations is not comprehensive enough. Most of the research on substations in China is to evaluate the economic benefits of energy-saving improvement of substations. There are problems of incomplete evaluation indicators and si...
