Gas Compressor System Simulation using Functional Mockup Interface for Human Machine Interface and Control

This paper describes a gas compressor (GCS) system simulation for the purpose of verifying a controller’s operation and interfacing simulation with measured data. The GCS is used to collect and compress low pressure gas streams for transmission into larger higherpressure lines. This system is simulated with ANSYS TwinBuilder. It includes models of the compressor, motor, bypass valve, and piping along with pressure sources for the low and high-pressure lines, which are controlled with measured or test data. To cycle and pressurize the GCS, a controller is implemented using an FMU from ANSYS SCADE. To interact with the system and monitor current operating conditions, a human machine interface (HMI) is also implemented using ANSYS SCADE as an FMU.
