.2 + Type Of Combined-cycle Load Optimization Theory

The paper introduces a novel idea for the strategy of 2 + 1 300MW multiple-spindles layout combined cycle unit optimized operation and critical point.Chapter one introduces that at present, particularly this year, our country electric power is in short supply situations and proposes to increase electric power capital construction and improve electric wire netting technology method energetically. Have introduced two main tasks of research object and thesis.Chapter two introduces the features of each part of combined cycle unit, the mathematical models based on the characteristics of combined cycle unit are studied. This paper analyzes the operating status under various circumstance conditions and presents the strategy of combined cycle unit optimized operation and critical point according to units' economy. And compared with the data of the income and data of GE procedure , it makes the good result.Chapter three introduces that after recommending realizing DCS system of the scheme and AGC order in the power plant, the paper puts forward three solutions, determines to carry on the configuration to compile with Composer software at last, download the scheme to MFP module.Chapter four studies the function of DCS system in plant and performs the configuration by using Composer software. The rules and critical point are exchanged to logic codes in order to conform the conversion time and running methods, which make the units running more valid and effective.Chapter five makes a summary on some ideas and results from this thesis.
