Control Processes of CCGT Power Units Gas Turbines under the Changing Operational and External Climatic Conditions

摘要

Steam and gas technologies have currently been widely introduced in the energy sector. The development of binary power units in various climatic conditions has revealed a number of interdisciplinary problems related to the efficiency of the unit and its operational reliability. Due to the influence factors fuzziness, it is not possible to analyze them under normal operation. This study has been performed on a mathematical model of a CCGT power unit. The results of a management processes and influencing key factors study are presented. The results of the mathematical modeling reveal the physical problems of the structural synthesis of a multivariable ACS of a CCGT unit power, which, in turn, is associated with the organization of fuel supply to the combustion chamber and air to the compressor of a gas turbine unit. The new technical solution is justified, based on the results of a generalized thermodynamic analysis, and an assessment is made of its efficiency when the outside temperature is varied over a wide range of controlled loads.
