The deregulation of the electric power market has introduced strong competition, and as a result, power plant operators strive to develop advanced operational strategies to maximize the profitability given the conditions of the dynamic electric power market. In the deregulated electric power market, the operational strategies should match the evolving electric power market, and be capable of performing an optimization that is specific to a unit operating in a complex environment. A profit based, lifecycle oriented, and unit specific approach is proposed for more effective gas turbine power plant operational optimization, and methodologies for this approach are developed. This paper outlines an integrated, generic environment for unit-specific gas turbine power plant operational modeling and optimization, while several other follow up papers address specific operational optimization problems. The procedure is implemented for a generic combined cycle power plant with single gas turbine with the results demonstrating the feasibility of the proposed approach.

To solve the housing damage problem of a fractured compressor blade (CB) caused by an impact on the inner casing of a gas turbine in the seventh stage (from 15 stages), modifications of the trailing edge (TE) of the CB have been proposed, namely 6.5 mm curved cutting and a combination of 4 mm straight cutting with 6.5 mm curved cutting. The simulation results of the modifications in both aerodynamics variables Cl and Cd and the pressure ratio, including structural dynamics such as a normalized power spectrum, frequency, total deformation, equivalent stress, and the safety factor, found that 6.5 mm curved cutting could deliver the aerodynamics and structural dynamics similar to the original CB. This result also overcomes the previous work that proposed 5.0 mm straight cutting. This work also indicates that the operation of a CB gives uneven pressure and temperature, which get higher in the TE area. The slightly modified CB can present the difference in the properties of both the aerodynamics and the structural dynamics. Therefore, any modifications of the TE should be investigated for both properties simultaneously. Finally, the results from this work can be very useful information for the modification of the CB in the housing damage problem of the other rotating types of machinery in a gas turbine power plant.
