Embodiment Construction

[0094] In order to make the dynamic evaluation method of the present invention easy to understand, the implementation manner of the present invention will be described below in conjunction with the drawings and specific examples. The following takes the DMA area of ​​the pipe network at 7:55 to 8:00 on June 5, 2016, in the core urban area of ​​City S as an example, and selects 17 nodes for dynamic comprehensive evaluation under different indicators.

[0095] 1. Primary dynamic evaluation and weight determination

[0096] The primary evaluation of the operating status needs to determine the corresponding evaluation criteria based on SCADA historical data and industry standards, and some evaluation indicators need to be converted through penalty curves to obtain the evaluation vectors of the evaluation indicators in hydraulic performance and water quality performance.

[0097] (1) Selection of evaluation indicators

[0098] In the actual situation of water supply network operat...

Abstract

A water supply network operation state assessment method disclosed by the present invention is characterized by determining and selecting the indexes at the next moment according to the weight ratio of the different indexes within the preceding period of time, and then determining the assessment standards and dynamically assessing the operation state. According to the present invention, a dynamic assessment method is used, the operation states of a water supply network at different time periods are considered, different assessment standards are selected, and the comprehensiveness of the single index or the multiple indexes are assessed dynamically. Meanwhile, a grading dynamic assessment scheme is provided, thereby being able to assess the operation state of the water supply network more scientifically, accurately and comprehensively.

Description

technical field [0001] The invention belongs to the field of urban water supply, in particular to a method for evaluating the running state of a water supply pipe network. Background technique [0002] The operation status of the water supply pipe network has always been a concern of the water company. The evaluation of the operation status of the pipe network can help dispatchers analyze and understand the situation of the pipe network. The water supply industry association has formulated a set of scientific and practical pipe network evaluation standards. This standard evaluates the indicators of different pipelines and nodes, but does not consider the dynamic changes in the operation status of the pipeline network at different times, and the evaluation results are not suitable for water supply dispatching. As far as the actual scheduling is concerned, due to the peaks and troughs in the law of water use, the evaluation criteria for different periods should be different. ...
