Embodiment 1

[0044] Such as figure 1 As shown, the distribution network status assessment and diagnosis method based on the layered radar map method includes the following steps:

[0045] S1. Obtain historical data of distribution network status evaluation indicators.

[0046] S2. Combining the fuzzy analytic hierarchy process and the anti-entropy weight method to obtain the comprehensive weight of the diagnostic indicators of the current situation of the distribution network, and calculate the subjective and objective weights of the classification layer.

[0047] S3. Draw a radar chart according to the comprehensive weight of the distribution network status diagnosis index, and use the area of ​​the radar chart as the distribution network status diagnosis evaluation value.

Embodiment 2

[0049] Such as figure 2 Therefore, the distribution network status assessment and diagnosis method based on the layered radar map method includes the following steps:

[0050] S1. Select the evaluation index of the distribution network status.

[0051] When diagnosing and evaluating the status quo of the distribution network, it is necessary to select as comprehensive indicators as possible, so as to build a comprehensive and reasonable indicator system. When constructing the index system, it is required to ensure the comprehensiveness of the coverage of the index on the one hand, and to reflect the current level of the distribution network as completely as possible; Distribution network indicators. The distribution network status evaluation indicators in this embodiment include power supply capacity indicators, grid structure indicators, operation management indicators and equipment level indicators, as shown in Table 1.

Abstract

The invention discloses a power distribution network current situation assessment and diagnosis method based on a layered radar map method. The method comprises the following steps: obtaining historical data of a power distribution network current situation assessment index; synthesizing a fuzzy analytic hierarchy process and an anti-entropy weight method to obtain a comprehensive weight of the current situation diagnosis index of the power distribution network, and calculating subjective and objective weights of a classification layer; and drawing a radar map according to the comprehensive weight of the current diagnosis index of the power distribution network, and taking the radar map area as the current diagnosis evaluation value of the power distribution network. According to the method, visualization of diagnosis and evaluation of the power distribution network is achieved, and therefore the purpose of visual evaluation and diagnosis is achieved. Therefore, a rapid and efficient method is provided for power distribution network assessment and diagnosis workers.

Description

technical field [0001] The invention relates to the technical field of distribution network status evaluation, in particular to a distribution network status evaluation and diagnosis method based on a layered radar chart method. Background technique [0002] A reasonable and accurate planning scheme can effectively guide decision makers to carry out purposeful and prioritized upgrades and transformations of the distribution network for weak links in the power grid, thereby improving the power supply reliability of the distribution network, improving the power supply capacity of the distribution network, and reducing Distribution network operation and maintenance costs and improve the quality of power supply. Before planning the distribution network, it is necessary to evaluate and diagnose the current situation of the distribution network to find out its weak links, so as to formulate an accurate planning plan in a targeted manner. Traditional distribution network evaluatio...
