Dynamic comprehensive evaluation model of energy efficiency of natural gas gathering and transportation system
摘要
Abstract
The energy consumption systems of gas fields in the middle and late stages of development shall be evaluated and optimized.However,most of the existing static energy efficiency evaluation methods ignore ambiguity and randomness,and do not take into account the impact of time effect on evaluation results.It is necessary to upgrade and optimize the static algorithms.Taking the dynamic data of energy efficiency of one certain natural gas gathering and transportation system as the research object,this paper addresses these shortcomings by using the cloud model theory and the TOWA operator quadratic weighting method.Then,a dynamic comprehensive evaluation model of energy efficiency of natural gas gathering and transportation system is established by using the RS-entropy weighting method.Finally,each time sequence is evaluated by using Python programming language,and the dynamic comprehensive evaluation results of energy efficiency in the long-term dimension are obtained through dynamic dimension raising.The following results are obtained.First,the introduction of time weight vector allows for a better reflection of energy efficiency fluctuations in the long-term dimension and enriches the information content.Second,the dynamic comprehensive evaluation results show that the energy efficiency of the above mentioned gathering and transmission system is"average".The subsequent optimization efforts can focus on the boosting process which has a high proportion of energy consumption in the secondary indicators.Third,the analysis on the dynamic comprehensive evaluation results of energy efficiency of three gas fields verifies that the optimization model established in this paper are applicable to the comprehensive energy efficiency evaluation of most gas fields,demonstrating its extensive applicability.In conclusion,this model introduces uncertainty into energy efficiency evaluation to embody the dynamics and randomness of evaluation object over time,so as to identify the weak links of energy efficiency in the gathering and transportation system,strength the understanding on the energy efficiency system of natural gas gathering and transportation system,and provide more theoretical support for energy-saving and consumption-reducing decisions.关键词
