In this brief, constrained multi variable model predictive control (MPC) strategy is investigated for a GE9001E gas turbine power plant. So the rotor speed and exhaust gas temperature are controlled manipulating the fuel command and compressor inlet guide vanes position. A nonlinear model is introduced using conventional mathematical models and ARX identification procedure as gas turbine plant ...

This paper presents a novel strategy for implementing model predictive control (MPC) to a large gas turbine power plant as a part of our research progress in order to improve plant thermal efficiency and load-frequency control performance. A generalized state space model for a large gas turbine covering the whole steady operational range is designed according to subspace identification method w...

This demonstration project was intended to repower an existing plant facility, the Lakeside Station in Springfield, Illinois. A single Integrated Gasification Combined Cycle (IGCC) process train was planned to generate a net output of 60 megawatts. The plant consists of a combined cycle (gas turbine, heat recovery steam generator, steam turbine) power train located in the existing buildings and...

The design of a black liquor gasification/combined cycle (BLGCC) power/recovery system requires the selection of a specific gas turbine. There are many different models from which to choose, but with only a fixed set of output ranges that are determined primarily by original design decisions relating to aircraft applications. A perfect match between the fuel requirement of a gas turbine and the...

CO2 capture from fossil fuel power plants is increasingly proposed for greenhouse gases emission mitigation. It can be applied to coal power stations (with boiler and steam cycle or with gasification) or to natural gas combined cycles (NGCC). The first case is probably the most important in a mid-term perspective, due to: (i) the larger amount of avoided carbon per unit of electricity produced,...

Nowadays, extensive research has been conducted for gas turbine engines control due to growing importance of gas turbine engines for different industries and the need to design a suitable control system for a gas turbine as the heart of the industry. In order to design gas turbine control system, various control variables can be used, but in the meantime, fuel flow inserting into combustion cha...

The potential for improved performance of wave rotor cycles through the use of passage height variation is examined. A Quasi-one-dimensional CFD code with experimentally validated loss models is used to determine the flowfield in the wave rotor passages. Results indicate that a carefully chosen passage height profile can produce substantial performance gains. Numerical performance data are pres...

This paper concentrates on the modeling and control of distributed generation systems including fuel cell and gas turbine. The fuel cell is onnected to the power system through a dc/ac converter, which is equipped with both voltageand power-control loops. The gas turbine is also ssumed to be equipped with both voltage-control and generation (or frequency)-control loops. Moreover the gas turbine...

The temperature of exhaust gases from simple cycle gas turbine generation sets (GENSETs) is usually very high (around 500 C), and a heat recovery steam generator (HRSG) is often used to recover the energy from the exhaust gases and generate steam. The generated steams can be either used for many useful processes (heating, drying, separation etc.) or used back in the power generation system for ...
