Research On Simulation Of Daqing Oilfield Gas Turbine Power Plant MARK VI Control System

Natural gas power generation has a promising future compared to other energy sources,but the domestic gas turbine power plant has just begun to grow up,experienced power plant operators are barely needed.In order to train more excellent operators of gas turbine power plant,a multifunctional training software is required.MARK VI system is able to simulate operation functions and simulate the monitoring data of all kinds of operating status.At the same time,it could provide operators and technical managers with an objective judgement.Through its fault simulation function,the ability of analysis and dealing with emergency events is improved.According to the Daqing Oilfield Co.Power Group fired power plant #2 gas steam combined cycle power generation system,the system model of fired power plant is built and MARK VI system model and MARK VI system simulator is studied in depth in the dissertation.Firstly,the Daqing Oilfield Company Power Group fired power plant #2 gas steam combined cycle power generation system is selected as the research object.The mathematic model of prime mover,generator,excitation system and transformer is constructed and the structure and principle of gas steam combined power system is studied,which lays a foundation for the construction of MARK VI system simulating model;Secondly,based on the real data of Daqing Oilfield gas turbine power plant,SimuBuilder,a graphical model builder is utilized to construct the MARK VI system model.And the dynamic relationship between prime mover mechanical output power,generator output power and generator rotor speed is proved by the simulation experiment.The result corresponds with theoretical results.By the simulating engine SimuEngine,a man-machine visualized platform is built and custom programming is enabled.Finally,combined with the real data and the feature of gas power plant,the operating simulating and the graphical data system of MARK VI system is designed.The operation,function,technical target and hardware construction is then studied to design a simulating training system for gas power plant.Meanwhile,the dynamic response of the output power,air mass flow and exhaust gas temperature are analyzed to prove the validity of simulating results.In the application of the proposed training system,the operating environment,fault simulation,fault reshow,custom parameters and multiple practical function can be simulated approximately to the real facts.
