Abstract

In this paper, we consider the problem of calculating the optimal stationary mode of the gas transmission system. The maximum throughput of the gas transmission system was used as optimization criterion. Presented are the problem statement and the solution procedure. The original problem is divided into two interrelated components: the MINLP problem and the temperature calculation. To solve the MINLP problem, the Successive Linear Programming (SLP) method was used in combination with the branch and boundary method applied to integer variables. Modeling of compressor shop operating modes was performed using integer variables. Described are the approaches to improving the convergence of the algorithm: the introduction of an additional optimization subcriterion and additional constraints for gas flows through GTS sections.

Highlights

The gas transmission system (GTS) is a complex system that consists of a large number of objects including compressor shops, gas pipelines, etc
This paper covers the problem of calculating the GTS optimal stationary mode by the maximum throughput criterion
The proposed approaches are valid when calculating the optimal GTS stationary modes according to other criteria

Summary

Introduction

The gas transmission system (GTS) is a complex system that consists of a large number of objects including compressor shops, gas pipelines, etc. Control of GTS requires the calculation of optimal stationary modes per various criteria: minimization of gas consumption at compressor stations, throughput maximization and other [1]. We consider approaches to optimizing the GTS stationary mode according to the maximum throughput criterion. The proposed approaches are valid when using other optimization criteria (minimization of gas consumption at compressor stations etc.). Another approach to improvement of the algorithm convergence is to introduce additional constraints on gas flows through GTS sections, starting with the iteration number t t1 : (5)
