A safety evaluation method of gas storage and distribution station based on BP neural network

Abstract

The invention discloses a safety evaluation method of a gas storage and distribution station based on a BP neural network. The method comprises the following steps: 1, according to the execution standard and the process flow of the gas storage and distribution station, determining an index system of the safety evaluation of the gas storage and distribution station, including an evaluation index and a scoring standard; 2, constructing the topological structure of the BP neural network, and establishing a safety evaluation model based on the BP neural network; 3, collecting the evaluation indexparameters and safety evaluation results of the gas storage and distribution station as training samples of the neural network; 4, obtaining a safety evaluation model of learning and train from a training sample and constructing a database; 5, forming an inference mechanism in which that network output error is within the allowable range; Step 6, the safety of the gas storage and distribution station being predicted: the safety evaluation grade is determined as A safety, B safety, C general safety, D relatively unsafe, E unsafe. The invention has the advantages that the subjective influence ofmanual evaluation is reduced and the accuracy and objectivity are improved; easy operation and high efficiency are realized.

Description

technical field [0001] The invention relates to the technical field of gas storage and distribution, in particular to a safety evaluation method for a gas storage and distribution station based on a BP neural network. Background technique [0002] Natural gas is an important fuel and chemical raw material, widely used in various fields of industry and civil use. Once a safety accident occurs in a gas storage and distribution station, it will cause serious casualties and huge property losses. Therefore, the safety issues of gas storage and distribution stations that receive, fill and store LNG are becoming more and more prominent. Proposing an effective safety evaluation method for gas storage and distribution stations is of great significance to prevent major safety accidents. [0003] The safety evaluation of gas storage and distribution station is the evaluation of the safety degree of a certain gas storage and distribution station, which provides an important basis for t...
