Combined Cycle Gas Turbine (CCGT) integrates two cyclesBrayton cycle (Gas Turbine) and Rankine cycle (Steam Turbine) with the objective of increasing overall plant efficiency. In modern gas turbine the temperature of the exhaust gases is in the range of 500 oC to 550 oC. Modern steam power plants have steam temperature in the range of 500 oC to 630 oC. Hence gas turbine exhaust can be utilized ...

In the Modern scenario, the naturally available resources for power generation are being depleted at an alarming rate; firstly due to wastage of power at consumer end, secondly due to inefficiency of various power system components. A Combined Cycle Gas Turbine (CCGT) integrates two cycles- Brayton cycle (Gas Turbine) and Rankine cycle (Steam Turbine) with the objective of increasing overall pl...

Graphical representation is useful to illustrate complex structure in a direct or intuitive way. A graph is a symbolic of network and its connectivity can be simplified as a set of linked notes. In recent studies of complex control system, directed graph has been introduced to define and interpret the interconnection structure underlying the dynamics of the interacting subsystem. Generally, the...

In order to build accurate model for complicated nonlinear system in engineering, like boiler–turbine system, a novel fuzzy-modeling approach is proposed, which is based on a new fuzzy c-regression model (NFCRM) clustering algorithm and is able to determine the right number of rules automatically. In this method, NFCRM is applied to build the fuzzy structure and then identify the premise parame...

In present work ,a boiler turbine plant is presented as a 2x2 MIMO system with high multivariable interaction having two manipulated variables namely the governor valve position and the fuel flow rate and two control variables namely generated electric power and the steam pressure. The controller for this plant has been designed using conventional PID and MPC technique by first investigating th...

Power generation today is an increasingly demanding task, worldwide, because of emphasis on efficient ways of generation. A power station is a complicated multivariable controlled plant, which consists of boiler, turbine, generator, power network and loads. The power sector sustainability depends on innovative technology and practices in maintaining unit performance, operation, flexibility and ...

The load following operation of coal-fired boiler-turbine unit in power plants can lead to changes in operating points, and it results in nonlinear variations of the plant variables and parameters. As there exist strong couplings between the main steam pressure control loop and the power output control loop in the boiler-turbine unit with large time-delay and uncertainties, automatic coordinate...

To maximize the system-level heat integration, three retrofit concepts of waste heat recovery via organic Rankine cycle (ORC), in-depth boiler-turbine integration, and coupling of both are proposed, analyzed and comprehensively compared in terms of thermodynamic and economic performances. For thermodynamic analysis, exergy analysis is employed with grand composite curves illustrated to identify...
