Development of a Mathematical Model for Determining the Leakage Point of the Gas Pipeline at Fuel Supply Energy Complexes and Facilities

摘要

This study presents the results of a new approach to detecting the gas leak while accident on the high-pressure gas pipeline at fuel supplying of power facilities. To solve the task developed a mathematical model for solving problems based on the computational mathematics methods with regard to the determination of pressure losses along the gas pipeline. This model is based on the motion equations for the flow of real gas, takes into account the factor of compressibility and temperature unevenness along the pipeline which allows reducing the recovery time of the energy complex during an accident and increasing its reliability. The method for finding the gas leak is developed. Based on this method a PC program was developed to determine the leakage location under real conditions. The results of implementation of the new method are presented and compared with real statistics of gas leak accidents. This method contribute to the mathematical modeling of the processes of gas flow through the pipeline. The conclusions were formulated.
