The object of research: The expander of the excess gas pressure utilization plant. Investigated problem: Increasing the efficiency of the process of utilization of excess gas pressure during its distribution from main high-pressure gas pipelines. Development of hardware and software tools that provide automation of the process of regulating flow parameters under the influence of time-varying disturbances. The main scientific results: A mathematical model of the process of utilization of excess gas pressure has been developed, and an experimental assessment of its adequacy has been carried out. With the help of the Matlab application “Linear Analysis Points”, the description of the object is linearized, which makes it possible to obtain its representation in the state space. The area of practical use of the research results: The sphere of application of the results of the study is automation objects related to the regulation of gas flow parameters. The results of identification of model parameters provide an opportunity for the synthesis of the process controller. Innovative technological product: In accordance with the task of increasing the efficiency of the process of utilization of excess gas pressure when it is distributed from the main high-pressure gas pipelines, a mathematical model of the channel for controlling the speed of rotation of the turbine (expander) has been developed, which serves as the basis for the synthesis of the regulator for the utilization process. Scope of the innovative technological product: The developed model can be used in the construction of turbine speed controllers, which are used in the generation of electricity. The approach to the linearization of the description of the control object makes it possible to automate the process of identifying its parameters.
