Design And Research Of Gas Turbine Auxiliary Control System

Gas turbine as a core production equipment, has been widely used in the fields such as multiple production in power plant. Especially in recent years, along with the ascension of the whole level of social productive forces, the scope of application of gas turbine is more and more widely, its performance is also in constant improvement. This paper is based on the choice of a subject.This research introduces the structure features and key technologies of GE 9FA gas turbine, it is because this will be the GE 9FA gas turbine as the main research object, to study the auxiliary control system. Auxiliary control system of GE 9FA gas turbine is studied, introduces the main function and auxiliary control system and component.First of all, in this paper, the gas turbine and the operation of the development of control system are introduced, the key is GE 9FA gas turbine and auxiliary machinery for the analysis of the structure and principle, has been clear about the auxiliary system of the importance of the host structure in operation process;Secondly, in view of the gas turbine lubricating oil pump control, initiating device control of auxiliary fan control, speed and acceleration control, oil and gas separator, air system, ventilation and temperature control, etc., to the study on analyzed emphatically the important auxiliary role in the process of gas turbine operation and its working principle;Again, from the aspects of hardware, to GE 9FA gas turbine auxiliary control system design and research, the auxiliary control system of auxiliary control system hardware control logic design analysis.Finally, from the aspects of software, set up and the network system design of the controller, start of auxiliary control system, hot plate, ignition sequence, warm-up sequence, parking order and turning control logic of working procedure such as design and analysis.
