Анализ характеристик блочно-комплектной турбокомпрессорной установки с газотурбинным приводом на основе её комплексной математической модели

Abstract

На основе созданной в Специальном конструкторском бюро ПАО «Сумское НПО им. М.В. Фрунзе» комплексной математической модели (КММ), реализованной в виде программно- вычислительного комплекса САРТУ-КС-М, выполнен анализ технологических и термодинамических параметров блочно-комплектной турбокомпрессорной установки, созданной на основе центробежного компрессора и газотурбинного привода мощностью 8,0 МВт. Установка предназначена для сбора и транспорта нефтяного газа в условиях эксплуатации Уренгойского нефтегазоконденсатного месторождения (Россия).

This paper gives the computation data and the analysis data for the power efficiency of the turbocompressor plant (TCP) with the gas-turbine drive based on its design and actual operation modes. The need for the use of an advanced design method and appropriate software and hardware to develop the TCP equipment, to perform the commissioning of it and to provide its operation has been substantiated. The block –assembled turbocompressor plant that was created using the centrifugal compressor and gas turbine drive of 8.0 MW was used as a test facility. The structure of the programming and computing system CAPTU-KC-M used for the analysis of the working process of the block-assembled TCP has been given. The mathematical model of the system is represented as a set of the computation procedures realized in the program mode according to the typical structure of the flow diagram of the plant that allows for the TC design, including its thermodynamic analysis. The operation parameters of TCP used for the oil gas have been analyzed. The TCP efficiency was calculated using the method of exergy balances. The values of the exergic efficiency factor of the analyzed plant for actual and design modes reach 0,112 and 0,144, respectively. Taking into consideration the obtained data the scientists worked out the recommendations to increase the energetic efficiency of the plant operation.
