Small Turbines in Distributed Utility Application


Book Description

Implementing distributed utility can strengthen the local distribution system and help avoid or delay the expense of upgrading transformers and feeders. The gas turbine-generator set is an attractive option based on its low front-end capital cost, reliable performance at unmanned stations, and environmental performance characteristics. This report assesses gas turbine utilization issues from a perspective of fuel supply pressure requirements and discusses both cost and operational factors. A primary operational consideration for siting gas turbines on the electric distribution system is whether the local gas distribution company can supply gas at the required pressure. Currently available gas turbine engines require gas supply pressures of at least 150 pounds per square inch gauge, more typically, 250 to 350 psig. Few LDCs maintain line pressure in excess of 125 psig. One option for meeting the gas pressure requirements is to upgrade or extend an existing pipeline and connect that pipeline to a high-pressure supply source, such as an interstate transmission line. However, constructing new pipeline is expensive, and the small volume of gas required by the turbine for the application offers little incentive for the LDC to provide this service. Another way to meet gas pressure requirements is to boost the compression of the fuel gas at the gas turbine site. Fuel gas booster compressors are readily available as stand-alone units and can satisfactorily increase the supply pressure to meet the turbine engine requirement. However, the life-cycle costs of this equipment are not inconsequential, and maintenance and reliability issues for boosters in this application are questionable and require further study. These factors may make the gas turbine option a less attractive solution in DU applications than first indicated by just the $/kW capital cost. On the other hand, for some applications other DU technologies, such as photovoltaics, may be the more attractive option.

A spreadsheet is also given to help readers apply the simple load model of the IEC standard for small wind turbine safety. Small Wind Turbines represents the distilled outcome of over twenty years experience in fundamental research, design and installation, and field testing of small wind turbines. Small Wind Turbines is a suitable reference for student projects and detailed design studies, and also provides important background material for engineers and others using small wind turbines for remote power and distributed generation applications.




Microturbines


Book Description

Small-scale gas turbines, known as Microturbines, represent an exciting new development in gas turbine technology. They can run in size from small, human-scale machines down to micro-sized mini-machines that can barely be seen by the naked eye. They also run a great diversity of fuel types, from various types of commercial gases to waste-generated gases. This new book by industry expert Claire Soares will fully describe the various types of microturbines, their applications, and their particular requirements for installation, maintenance and repair. It will explain how a microturbine the size of a refrigerator can power an entire school, hospital or small factory, which is particularly useful for onsite, remote installations. The book will also show how microturbines can be paired with one or more fuel cells to form a hybrid energy source, or can be teamed with any source of distributed power, such as a mall hydro-turbine or a wind turbine. Moreover, the reader will learn how microturbines can run on a variety of fuels that are far cruder than those required by most standard gas turbines; they can be made to run, for instance, using gas from a landfill or biomass source. The reader will find detailed information on costs, specifications, and maintenance and repair guidelines. Ample references and resources will provide the reader with tools for finding manufacturers and product specifications for their own particular needs. - Covers major categories of microturbines, including factors common to their design, installation, operation, optimization, maintenance, and repair - Invaluable guidance on market factors and economics affecting microturbines and their applications, particularly for distributed power generation - Provides current case studies showing microturbines used in hybrid systems with fuel cells and other types of power generation systems

Siting Guidelines for Utility Application of Wind Turbines. Final Report


Book Description

Utility-oriented guidelines are described for identifying viable sites for wind turbines. Topics and procedures are also discussed that are important in carrying out a wind turbine siting program. These topics include: a description of the Department of Energy wind resource atlases; procedures for predicting wind turbine performance at potential sites; methods for analyzing wind turbine economics; procedures for estimating installation and maintenance costs; methods for anlayzing the distribution of wind resources over an area; and instrumentation for documenting wind behavior at potential sites. The procedure described is applicable to small and large utilities. Although the procedure was developed as a site-selection tool, it can also be used by a utility who wishes to estimate the potential for wind turbine penetration into its future generation mix.
