[Abstract]:In the design of gas turbine control system, the auxiliary control system is as important as the main engine control system, which will have a great impact on the performance of the gas turbine, and will also have a certain impact on its service life. Therefore, we must pay attention to the design and implementation of auxiliary control system for gas turbine. It is on this basis that this paper chooses this subject. In this paper, the structural characteristics and key technologies of GE 9FA gas turbine are studied, and the auxiliary control system of GE 9FA gas turbine is studied, and the main functions and components of the auxiliary turbine control system are analyzed. Finish the hardware and software design of GE 9FA gas turbine auxiliary machine control system. Firstly, this paper introduces the development of gas turbine and its running control system, especially analyzes the structure and principle of 9FA heavy-duty gas turbine and auxiliary machine of GE Company, including the working principle of gas turbine. The structure of main engine and auxiliary machine, combined with the work and control principle of gas turbine, make clear the importance of auxiliary machine system to the structure of main engine in the course of operation. Secondly, the control of lubricating oil pump, start-up device, speed and acceleration, fan control of oil and gas separator, air system control, ventilation and temperature control are studied. The function and working principle of each important auxiliary machine in the operation of gas turbine are analyzed emphatically. Thirdly, from the hardware aspect, the design and research of 9FA gas turbine auxiliary machine control system of GE company are carried out, and the hardware control logic of auxiliary machine control system in auxiliary machine control system is designed and analyzed. At the same time, the protection measures during the operation of gas turbine are further studied to ensure the safety of gas turbine during operation. Finally, from the aspect of software, the design of the controller and the network system are studied. The starting, hot disk car, ignition sequence, warming order in the auxiliary machine control system are studied. Design and analyze the control logic of parking sequence and other working procedures.
