Description

Technical Field

[0001] The invention relates to the field of data processing, and in particular to a comprehensive evaluation method for environmentally friendly insulating gas based on multi-dimensional dynamic weights. Background Art

[0002] Insulating gas has good electrical insulation properties and arc extinguishing ability, and is widely used in gas-insulated power equipment. Traditional sulfur hexafluoride insulating gas will destroy the ozone layer and cause the greenhouse effect. Therefore, the research and development of new environmentally friendly insulating gases that are friendly to the ozone layer has become a hot topic in this research field. New insulating gases generally exist in the form of compounds. The gas itself and the decomposition gas produced under the action of the electric field of power equipment may have an impact on the environment and personnel safety. In addition, the economic cost of developing and producing different insulating gases is also different. Therefore, how to conduct a multi-dimensional comprehensive evaluation of the performance of environmentally friendly insulating gases is an important issue that needs to be solved in electrical engineering.

[0003] In the existing gas evaluation research, most of them are single-dimensional evaluations based on the purpose of the gas, such as whether the insulation performance is good, whether the environmental protection is compliant, whether the toxicity is compliant, whether the decomposition characteristics meet expectations, etc. However, in actual use, the various physical / chemical properties of the gas will play their role. Directly integrating the evaluation information of a single dimension will result in the problem of relatively fragmented evaluation of each indicator. In addition, based on different usage scenarios, the requirements for different performance are completely different. The current solution cannot directly derive the optimal choice, and the efficiency and accuracy of manual selection are poor. Therefore, how to comprehensively consider the multi-dimensional indicators that affect the performance of insulating gas, combined with the degree of difference in the requirements of each dimensional indicator in actual engineering, and comprehensively evaluate the insulating gas to obtain the optimal choice under different needs is a technical problem that urgently needs to be solved.

[0022] The technical solution of the present invention is described in detail with specific embodiments below. The embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0023] Example: A comprehensive evaluation method for environmentally friendly insulating gas based on multi-dimensional dynamic weights, such as Figure 1 As shown, the following steps are included: Determine the comprehensive evaluation index of the environmentally friendly insulating gas, collect data on the gas to be evaluated based on the comprehensive evaluation index, and obtain the evaluation index value of each dimension corresponding to the gas to be evaluated.

[0024] include: Establish a comprehensive evaluation index system for environmentally friendly insulating gas performance; Based on the comprehensive evaluation index, data of the gas to be evaluated is collected to obtain the initial value of the evaluation index; The initial values ​​of the evaluation indicators of each dimension in the indicator system are normalized and dimensionless, and the evaluation index value I=(I1,I2,...,I m ), I i (i=1,2,…,m) is the normalized and dimensionless evaluation index value of each dimension.

[0025] In this embodiment, Figure 2 As shown in the figure, the established comprehensive evaluation index system mainly includes four main dimensions, namely insulation, safety, environmental protection and economy, and contains eight indicators under each corresponding dimension, namely breakdown field strength I1, arc extinguishing ability I2, inhalation toxicity I3, carcinogenic toxicity I4, greenhouse effect I5, environmental toxicity I6, manufacturing cost I7 and maintenance cost I8.

[0026] Among them, the normalization and dimensionless algorithm of the indicator value is: In the formula, I represents the normalized dimensionless value of the indicator, and I 实际 Indicates the actual value of the indicator, I 实际maxIndicates the maximum value among the actual values ​​of the indicator.

[0027] A unit nonlinear basis function is established, and the evaluation index values ​​are substituted into the unit nonlinear basis function to obtain the influence of each dimensional evaluation index on the comprehensive performance.

[0028] include: The nonlinearity of the impact of each dimensional evaluation index on the comprehensive performance of insulating gas is analyzed, and a unit nonlinear basis function is established. The evaluation index value is substituted into the unit nonlinear basis function, and the impact of each dimensional evaluation index on the comprehensive performance is obtained as F = [f(I1), f(I2), ..., f(I m )], where f is the unit nonlinear basis function, I i (i=1,2,…,m) is the normalized and dimensionless evaluation index value of each dimension.

[0029] like Figure 3 As shown, the unit nonlinear basis function includes: In the formula, according to the influence of different evaluation indicators on the comprehensive performance, the four types of basis functions are divided into: logarithmic increasing type f1, exponential increasing type f3, negative logarithmic decreasing type f2, and negative exponential decreasing type f4.

[0030] According to the law of the influence of the evaluation index on the comprehensive performance of the insulating gas, the corresponding unit nonlinear basis function is selected. Among them: for the index with a larger value, the better the performance of the insulating gas, the increasing basis function f1 or f3 is selected; for example, the breakdown field strength and arc extinguishing ability.

[0031] For indicators whose performance of insulating gas deteriorates as the value of the indicator increases, the decreasing basis function f2 or f4 is selected; for example, inhalation toxicity, greenhouse effect, etc.

[0032] In addition, according to the change in the degree of influence of the increase in the index value on the comprehensive performance, a concave curve or a convex curve in the increasing or decreasing function is selected. For example, as the breakdown field strength increases, the insulation performance of the insulating gas increases more and more, and the corresponding base function is f3.

[0033] In this embodiment, after analyzing and selecting a reasonable basis function, the influence of each index on the comprehensive performance of the insulating gas is F=[f3(I1), f3(I2), f2(I3), f2(I4), f4(I5), f2(I6), f2(I7), f4(I8)], as shown in Table 1: Table 1 Index parameters and data processing results of the gas to be evaluated in the embodiment The dynamic weights of the impact of evaluation indicators on comprehensive performance are established, and the dynamic weights are assigned according to the differences in performance requirements of environmentally friendly insulating gases in different dimensions under actual working conditions.

[0034] include: Establish the dynamic weight of the evaluation index on the comprehensive performance, denoted as W = [w1(I1),w2(I2),...,w m (I m )], according to the differences in the performance requirements of different dimensions of insulating gas under actual working conditions, the dynamic weight is determined by expert scoring and / or hierarchical analysis method, where w i (I i ) is the dynamic weight corresponding to the i-th indicator, and the sum of all weights is 1.

[0035] For example, in this embodiment, when the actual working conditions require that the gas has higher insulation performance, the dynamic weight is determined by expert scoring and hierarchical analysis method as W1 = [0.25, 0.25, 0.14, 0.06, 0.1, 0.1, 0.04, 0.06]; when the actual working conditions require that the insulating gas has higher environmental protection and biosafety while meeting the insulation requirements, the dynamic weight is determined by expert scoring and hierarchical analysis method as W2 = [0.05, 0.05, 0.28, 0.12, 0.2, 0.2, 0.04, 0.06].

[0036] An evaluation model for the comprehensive performance of environmentally friendly insulating gas is established. Matrix calculation is performed based on the influence of each dimensional evaluation index on the comprehensive performance and the assigned dynamic weights to obtain the comprehensive performance evaluation results.

[0037] In this embodiment, a mathematical model S = WF for evaluating the comprehensive performance of environmentally friendly insulating gas is constructed. T , W is the dynamic weight, F is the impact of each dimensional evaluation index on the comprehensive performance, and the superscript T represents the matrix transpose.

[0038] In this embodiment, the data and dynamic weights in Table 1 are substituted into the evaluation model, and the other comprehensive performance evaluation results of the insulation to be evaluated are obtained as S1=[0.3189, 0.7524, 0.6182] and S2=[0.2265, 0.5509, 0.5744].

[0039] The gas with the highest score in the comprehensive performance evaluation results is selected as the optimal choice.

[0040] Based on the comprehensive evaluation results of dynamic weights, it can be seen that insulating gases B and C are the optimal choices under two different working conditions with high insulation requirements and high environmental safety requirements, respectively.
