This paper describes the modeling of a 27 MW combined cycle cogeneration plant with 10,000 tons chilled water central cooling facility. The cogeneration plant is designed to provide heating, cooling and electricity from a single fuel source viz., natural gas, though the gas turbines do have an inbuilt dual fuel combustion system. The topping cycle of the combined cycle cogeneration plant consists of two gas turbines each producing 11 MW of electric power at full load. The energy of the exhaust gases from these gas turbines is then utilized to generate steam in two heat recovery steam generators. The heat recovery steam generators are duct fired using natural gas to meet the peak steam load. In the bottoming part of the combined cycle, the steam from the heat recovery steam generators is expanded in a backpressure steam turbine to supply steam to the campus at about 963 kPa, generating an additional 5.5 MW of electric power in this process. There is no condenser wherein the campus acts as a sink for the steam. The central cooling facility is designed to supply 10,000 tons of chilled water out of which 3800 tons is supplied by two steam driven centrifugal chillers, which utilize a part of the steam supplied to the campus and the remaining by the centrifugal electric chillers. The combined cycle cogeneration plant along with the central chilled watercooling facility is modeled in a commercially available flexible cogeneration software package. The model is built based on the design data available from design manuals of gas turbines, heat recovery steam generators, backpressure steam turbine and centrifugal chillers. A parametric study is also done on the model to study the effect of different parameters like fuel flow rate, temperature etc on the output of the turbine and efficiency of the plant. Modeling of the inlet air-cooling of the gas turbine using an absorption chiller and electric chiller is also presented. Finally the paper discusses these results.

Cogeneration heat and power plant has a long history of application in many types of industries, buildings etc, because of its benefits, such as environmental, energy and cost saving. A useful type of cogeneration plants is the combined cycle cogeneration plant. In this paper, thermodynamic optimization analysis for this type of plant (with backpressure steam turbine) and its performance criteria have been developed. It has been shown that the most efficient plant, for a target stack temperature could be achieved when the gas turbine and steam cycle are designed for maximum specific net work and cycle efficiency respectively. For validation purpose, some standard market gas turbines, which have maximum of 6% error with the basic thermodynamic model, have been chosen in this study. Also it has been shown that the results of optimization of cogeneration systems are in good agreement with those of standard turbines.

The Cost

Abstract Exegetic and thermoeconomic analysis were performed for a 500-MW combined cycle plant and a 137-MW steam power plant without decomposition of exergy into thermal and mechanical exergy. A unit cost was assigned to a specific exergy stream of matter, regardless of its condition or state in this analysis. The calculated costs of electricity were almost same within 0.5% as those obtained by the thermoeconomic analysis with decomposition of the exergy stream for the combined cycle plant, which produces the same kind of product. Such outcome indicated that the level at which the cost balances are formulated does not affect the result of thermoeconomic analysis, that is somewhat contradictory to that concluded previously. However this is true for the gas-turbine cogeneration plant which produces different kinds of products, electricity and steam whose unit costs are dominantly affected by the mechanical and thermal exergy respectively.

This Paper describes the efforts required to operate two steam turbine-driven centrifugal natural gas compressors at significantly reduced rotative speeds. Natural gas is used to power a 420 MW combined cycle cogeneration plant. Normally, the plant uses natural gas fuel at supply line pressure and the two compressors are on idled standby. The goal of the project is to reduce motive steam consumption in the steam turbine driving the natural gas compressors. The present operating mode, or idle mode, is where both natural gas compressors recycle compressed gas via dedicated intercoolers. This mode of operation occurs about 95% of the time. The remaining 5% of the time is when natural gas compressors boost the trunk line pressure in order to deliver fuel to the gas turbine combustors. Both natural gas compressor trains are designed for rapid increase of rotative speed in case one natural gas compressor is shut down. In order to put a natural gas compressor on hot standby slow-roll condition, a special, dedicated slow roll line is proposed for the fine control of the rotative speed.

In June 1983 Power Systems Engineering, Inc. began engineering of a base loaded 465 MW (net) combined cycle cogeneration plant (Figure 1) designed to sell up to 1,150,000 lb/hr (145.0 kg/s) of steam to a chemical plant in Houston, Texas, and sell up to 550,000 kW of electric power to the local electric utility (Houston Lighting & Power). Power Systems designed the plant, specified and procured equipment, arranged $220 million of project financing, will manage the construction of the plant, and will operate the plant. Power Systems negotiated the long-term steam contract with the chemical company and the power contract with HL&P. In addition, Power Systems obtained all permits and contracted for a long-term fuel supply.
