Problems solved by technology

No matter what kind of technical route it is, it does not consider the response strategy after the power point is decommissioned. Especially for a specific project, how to use the original site when the unit is decommissioned and the alternative plan for the power point after decommissioning are not considered, which cannot reflect The management concept of the whole life process

Embodiment 1

[0054] see Figure 1-2 , an evaluation method for the strategy of serving main power points around cities, including the following steps:

[0055] Establish a hierarchical system structure according to several arrival strategies; the hierarchical system structure includes a target layer, a criterion layer, a sub-criteria layer and a program layer from top to bottom; the sub-criteria layer is at least one; the rule layer includes all The constraint condition B of the service strategy; each of the sub-criteria layers includes the constraint condition C of the service strategy; the constraint condition C is the subordinate constraint condition of the constraint condition of the upper layer of the sub-criteria layer; as In one embodiment of the present invention, the constraint condition C of the first sub-criteria layer is more specific than the constraint condition B of the criterion layer, and it is a subordinate constraint condition, and the correlation between the constraint ...

Embodiment 2

[0061] A method for evaluating the arrival strategy of main power supply points around the city. On the basis of Embodiment 1, the judgment matrix is ​​constructed according to the hierarchical system structure, specifically:

[0062] Based on an element of this layer, use the comparison scale r ij Indicates the importance of the i-th element of the next layer relative to the j-th element; among them, when the criterion layer and the sub-criteria layer or the sub-criteria layer and the sub-criteria layer establish a judgment matrix, if the constraint condition C has nothing to do with the reference element, then compare the standard degree r ij =0; In an embodiment of the present invention, using image 3 The value rules shown to determine the comparison scale r ij value. In this embodiment, the number of sub-criteria levels is 1, and the correlation between upper-level constraints and lower-level constraints is as follows: Figure 4 , where the sub-criteria layer constrai...

Embodiment 3

[0077] An evaluation method for the arrival strategy of main power supply points around the city, on the basis of the second embodiment, the weight of each constraint condition of the last layer of sub-criteria layer is obtained, and the last layer of sub-criteria layer is corrected according to the weight The weight vector of , specifically:

[0078] Obtain the evaluation values ​​of several experts on the i-th service strategy under the constraints C of the last sub-criteria layer, and form an evaluation matrix U i =(u ijk′ ) m′×n′ ; Among them, m' is the number of constraints in the last sub-criteria layer, n' is the number of experts, u ijk′ is the evaluation value of the k′th expert under the jth constraint condition C under the i-th service strategy;

[0079] Perform normalization processing on the evaluation matrix to obtain a standardized evaluation matrix P i =(p ijk′ ) m′×n′ ,in, min(u ij ) and max(u ij ) represent the minimum value and maximum value among ...

Abstract

The invention relates to a method for evaluating an in-service strategy of a main power supply point around a city. The method comprises the following steps: establishing a hierarchical system structure according to a plurality of in-service strategies; the hierarchical system structure comprises a target layer, a criterion layer, a sub-criterion layer and a scheme layer from top to bottom; constructing a judgment matrix according to the hierarchical system structure; the judgment matrix is obtained according to elements of two adjacent layers; obtaining a weight vector of each judgment matrix through a fuzzy analytic hierarchy process; obtaining the weight of each constraint condition of the last sub-criterion layer, and correcting the weight vector of the last sub-criterion layer according to the weight; and obtaining a final weight vector of the target layer according to the weight vector of each layer, and obtaining an evaluation result of each in-service strategy according to the final weight vector. According to the method, the related constraint conditions are extracted, the in-service strategy is evaluated on the basis of the entropy weight method and the hierarchy method, and the influence of all the constraint conditions on the in-service strategy is considered.

Description

technical field [0001] The invention relates to an evaluation method for the arrival strategy of main power supply points around cities, and belongs to the field of electric power technology. Background technique [0002] my country's power structure is dominated by coal-fired power generation. From the perspective of future development, thermal power will still occupy a dominant position in my country's power structure for a long period of time. Facing the current and long-term development situation of coal-fired thermal power units, study its installed structure and current situation, conduct a comprehensive analysis of the economical and safe reasonable life of the units, and obtain as accurate and quantifiable as possible the decommissioning expectations of thermal power generation units in service, which is a great contribution to our country. The planning and construction of coal-fired thermal power units provide basic and guiding data, which is of great significance ...
