Study on Parameter Optimization of Gas Network Based on Reliability

摘要

Entropy is taken as an indirect index to measure the reliability of gas distribution network. The entropy function is set up. According to principle of maximum entropy, the maximum entropy model is established. With the relative entropy which is the ratio of actual entropy and maximum entropy as the reliability constraint, the diameter optimization model is set up and solved by improved genetic algorithm. Through actual engineering example, the optimization model with reliability constraint and optimization arithmetic in this paper can acquire satisfied solutions to engineering project and have certain reference value for diameter optimization design of gas distribution network.
