A real-time gas turbine simulation model for control logic evaluation

Abstract

During our development of a gas turbine control system, we need to evaluate the correctness and completeness of the control logic before conducting a hardware-in-the-loop (HIL) test. For this purpose, a pure software simulation framework which includes virtual DPU (VDPU) and gas turbine model interfacing through OPC protocol was proposed. A real-time gas turbine simulation model for this framework was developed. This gas turbine model was written in C++ and employs the object-oriented philosophy for maintenance and further development and it uses a non-iterative method to ensure the real-time capability to run simultaneously with the control logic. From the result of preliminary tests on this model, it shows to be able to simulate the response of real gas turbine to the instructions from the control system and suitable to evaluate the control logic.
