The Research On Control Technology Of Gas-steam Combined Cycle Unit

At present,the environmental pollution is becoming more and more serious.Gas power generation has the advantages of low pollutant discharge,wide output power,high reliability,good power generation,quick response and so on.With the increasing emphasis on environmental protection,all parts of the country gradually began to develop gas power generation.Dynamic mathematical model of gas-steam combined cycle unit,an important tool to analyze dynamic characteristics of.High accuracy of turbine performance analysis algorithm and a dynamic simulation model in engineering has important practical value.Through the establishment of simulation model,on the performance of gas steam combined cycle unit were simulation analysis,obtained the necessary to run the data.Binding on the unit basic control theory and the main control circuit,proposed a gas steam combined cycle unit frequency modulation function realization method,can realize the way forward of the gas turbine in frequency modulation in steam turbine control system increase the frequency modulation function,through the gas turbine to reserved interface On the control of gas turbine frequency modulation load,the characteristics of #1 gas steam combined cycle unit in Tianjin Binhai Power Co.,Ltd are investigated.Through the analysis of the power curve,the characteristics of the gas steam combined cycle unit under different load conditions,different disturbance conditions,and the maximum value of all the test results are compared with the standard values.The research on the characteristics of the Tianjin power grid gas steam combined cycle unit is filled.
