Study On Operation Technology Of Gas Turbine And Gas-Steam Combined Cycle Plant Unit

Several GTCC of invite public bidding has been put into production in succession, ourcountry pay more attention to Gas Turbine and GTCC units. So how to optimize andincrease the security and economy of the units has become a imperative problem.This paper mainly study the GTCC of GE9E which functions largely in our country,realized the indirect measurement of Gas Turbine's inlet temperature T3 through somemeasurable parameters such as T4. At the same time, it also realized the measurement ofT3 under the whole condition through the theoretical model which has been built.The paper makes a contrast between simply circulation and GTCC for three kinds ofways of IGV according the T3 and other measurable parameters, provides the bestevidence to simply circulation and GTCC. Have some certain evaluation to the actualfunction of plants.
