TABLE 2
(3) On-site electricity utilization unit
The characteristics of field electricity utilization can be summarized into 6 aspects: denuded, polytropic, vulnerable, temporary, environmental complexity, diffusive. Just because these characteristics of the field power utilization cause many on-site power utilization equipment and electric lines to have insecurity factors, easily cause electric equipment and line damage and cause electric safety accidents, such as: electric shock and electrical fire. If only one side of the using function is emphasized on the field power utilization, and the safety protection of the power utilization is neglected, the power utilization is inevitably damaged. The design of field power utilization urgently needs to meet the requirement of generating power utilization and ensure the safety and reliability of power utilization.
Wherein, for the field power unit, the field power unit is classified and evaluated according to the building information, the field power unit is recorded as X, and the subordinate electrical factors of the field power unit are recorded as XiCorresponding weight coefficient is ωxi。XiThe evaluation term of the subordinate was XijCorresponding weight coefficient is ωxij.

SFi-floor evaluation score;
ωi-floor weight factor;
S3-building electrical safety assessment integrated assessment score;
i-evaluating the number of buildings;
sLi-building floor assessment score;
ωLi-building weight coefficient
The electrical factors subordinate to the distribution box and the subordinate items (evaluation rules) of each electrical factor are shown in table 3.
TABLE 3
Then, a comprehensive evaluation score of the target unit is obtained according to the scores of the electrical safety management unit, the power transformation and distribution room unit and the field power utilization unit and corresponding weight coefficients, so that the electrical safety condition of the target unit is evaluated according to the comprehensive evaluation score.
In this embodiment, the total evaluation score of the electrical safety evaluation of the target unit can be calculated by adding the scores of the 3 evaluation major terms (i.e., the electrical safety management unit, the substation unit, and the field power utilization unit) obtained by the above calculation by multiplying the scores by the corresponding weight coefficients, and the calculation formula is as follows:
wherein:
z-the composite assessment score for the electrical safety of the target unit;
i is the number of evaluation units;
Si-evaluating the unit score;
ωi-evaluating the cell weight coefficients.
In the embodiment of the invention, the electrical safety evaluation grade of the target unit can be evaluated according to the comprehensive evaluation score of the target unit obtained by calculation and the preset evaluation standard. For example, a score of greater than 90 is judged as good, a score of 80-90 is judged as good, a score of 70-80 is judged as normal, a score of 60-70 is judged as poor, and a score of less than 60 is judged as very poor.
It should be noted that, in this embodiment, an electrical safety assessment report may be generated according to the electrical safety condition obtained by assessment, and the electrical safety assessment report may include six parts, namely, a compilation basis, an electrical risk factor analysis, division of an assessment unit, electrical safety assessment, a countermeasure measure, an assessment conclusion, and a recommendation.
It should be noted that, the above-mentioned evaluation items, the subordinate electrical factors thereof, and the evaluation details of each of the subordinate electrical factors may be adaptively increased or decreased according to actual needs. In addition, the weighting factor can be adjusted according to the actual evaluation situation, and the evaluation items and values listed in tables 1 to 3 are only one possible situation, but are not to be construed as limiting the present invention.
It should be noted that, in the above embodiment, each weight coefficient may be obtained by an analytic hierarchy process.
Specifically, in the present embodiment, the hierarchy can be divided into three types:
(1) the highest layer: only one element is included representing the overall goal of the decision analysis and is therefore also referred to as the overall goal layer.
The highest layer in the text is electrical safety evaluation;
(2) an intermediate layer: several layers of elements are included representing the sub-goals involved in achieving the overall goal, including various criteria, constraints, policies, etc., and are therefore also referred to as target layers.
The intermediate layer herein is: electric safety management, power transformation and distribution room and field power utilization;
(3) the lowest layer: representing possible schemes, measures, etc. to achieve each decision objective.
The lowest level here is the unit evaluation rule;
in this embodiment, the decision matrix can be easily constructed from the hierarchical structure described above. The method for constructing the judgment matrix comprises the following steps: each element having a downward membership (referred to as a criterion) is taken as the first element (located at the upper left corner) of the decision matrix, and the elements belonging thereto are arranged in the first row and the first column in order therebehind.
Aiming at the criterion of judging the matrix, which importance and how much importance two elements are compared with each other needs to be judged, and the importance degree is assigned according to 1-9 (the importance scale value is shown in the following table).
TABLE 4 significance Scale of significance table
In the present embodiment, the numerical value of the importance between two elements can be obtained by repeatedly asking a filling person (expert). Wherein, the filled judgment matrix is A ═ aij) n × n, the decision matrix has the following properties:
(1)aij〉0
(2)aji＝1/aji
(3)aii＝1
according to the above properties, the judgment matrix should have symmetry, so when filling in, a is usually filled in firstiiThen, only n (n-1)/2 elements of the upper or lower triangle need to be judged and filled in.
In special cases, the decision matrix may be transitive, i.e. satisfy the equation: a isij*ajk＝aik。
When all the elements of the judgment matrix are satisfied, the judgment matrix is called as a consistency matrix.
In this embodiment, the filled determination matrix is hierarchically ordered by using a certain mathematical method. The hierarchical ranking is the relative weight coefficient of each factor of each judgment matrix to the criterion thereof, so that the weight vector is essentially calculated. The calculation weight vector includes a characteristic root method, a sum method, a root method, a power method, and the like, and the sum method is briefly described here. The principle of the sum method is that for the consistency judgment matrix, each column is normalized to be the corresponding weight coefficient. For the non-uniformity judgment matrix, each column is normalized and then approximates to the corresponding weight coefficient, and the arithmetic mean value of the n column vectors is obtained to be used as the final weight coefficient. The specific formula is as follows:
it should be noted that, in the hierarchical ordering, the judgment matrix is checked for consistency.
In special cases, the decision matrix may have transitivity and consistency. A correct judgment matrix importance ranking has a certain logical rule, for example, if a is more important than B and B is more important than C, then logically, a should be more important than C, and if a result that a is more important than C appears when two are compared, the judgment matrix violates the consistency criterion, and is logically unreasonable.
Therefore, in practice, the judgment matrix is required to satisfy substantial consistency, and consistency check is required. Only by checking, it can be shown that the decision matrix is logically reasonable, and the analysis of the results can be continued.
The steps of the consistency check are as follows:
first, a consistency index c.i is calculated.
And secondly, determining a corresponding average random consistency index R.I by table lookup.
And (4) checking the following table according to different orders of the judgment matrix to obtain an average random consistency index R.I. For example, for a decision matrix of order 5, a table look-up yields r.i. ═ 1.12
Table 5 average random consistency index r.i. table (1000 positive and reciprocal matrix calculation results)
| Order of matrix | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
| R.I. | 0 | 0 | 0.52 | 0.89 | 1.12 | 1.26 | 1.36 | 1.41 |
| Order of matrix | 9 | 10 | 11 | 12 | 13 | 14 | 15 | |
