DEVICE AND METHOD FOR SIMULATING MOTOR-DRIVEN COMPRESSOR SYSTEM

PROBLEM TO BE SOLVED: To provide a simulation device for a system having a motor-driven compressor system, in which a shortage of starting torque and a surging is prevented, to economically operate a compressor system.SOLUTION: A simulation device 1 for the motor-driven compressor system stores, in a simulating part 40, a drive motor, a compressor driven by the drive motor, an intake throttle valve for controlling an intake flow rate of the compressor, and an anti-surge valve interposed in a pipe for returning a part of gas discharged from the compressor to the intake side of the compressor, by unit-modeling. Moreover, the simulation device 1 includes an input part 10 for inputting a design specification data of the compressor, a data setting part 50 for storing the design specification data, and a display part 30 for displaying an unsteady Q-H property and a required drive torque result simulated by the simulating part.
