This book was released on 2018-08-17 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2018 in the subject Engineering - Power Engineering, grade: 76, University of Manchester, course: Electrical and electronic engineering, language: English, abstract: Various converters, generators, and other high power facilities are situated several kilometres away from metropolitan areas. Thus, numerous renewable energy sources with an interconnection between the generation and transmission technology require an efficient and high capacity system which entails the implementation of gas-insulated lines. Gas-insulated lines (GIL) are a resourceful High Voltage (HV) transmission technology, which offers an alternative to traditional cables or overhead lines (OHL). Conventional cables are unable to provide adequate long-distance bulk power transmission as the ratings for voltage or useful power at the load aren’t sufficient in proportion to the line length. OHL with a lattice tower is a typical transmission method on shore with submarine Cross-linked Polyethylene (XLPE) cables or GIL utilised underground in challenging areas due to their flexibility and functional characteristics. A 420/550 kV GIL representation comprising of a multiphase model and constant RLC values presents an adequate analysis of the system. Fundamentally, GIL offers encouraging results given the high-pressured insulation medium, skin effect and returning current. Furthermore, by utilising a common platform for the simulations, a fair comparison with various HV transmission alternatives is accomplished. Additionally, this investigation incorporates an overview of the overvoltage and recovery characteristics of the simulated GIL with an adequate power supply concerning the installation of a synchronous generator and wind turbine. This research examines the economic factors with a distinctive focus on substantial investments made into offshore wind farms and GIL functioning in High Voltage Alternating Current (HVAC). The cost for this particular technical solution may provide an alternative to High Voltage Direct Current (HVDC) networks with Voltage Source Converters (HVDC-VSC) and submarine XLPE cables. The price per generating hour accumulates over time which reflects the total costs. Ultimately, the cost per unit is related to the demand. Finally, the literature review includes technical data, background information and a verification process for the simulation results.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers an insight into the insulation failures in GIS/GIL and provides practical guidance for improving the insulation reliability of epoxy-based spacers. High voltage gas-insulated apparatuses, including gas-insulated switchgears (GIS) and transmission lines (GIL), playing an important role in the global power transmission system. Epoxy-based spacers are key components in GIS/GIL, playing the role of electrical insulation and mechanical support. However, insulation failures frequently occur around the epoxy-based spacers, threatening the safe operation of the electric power system. Three topics make up this book, with seven to nine chapters in each topic. In the first topic, the surface charging and discharging behaviors of epoxy-based spacers are discussed to deepen the readers’ understanding on the insulation problems in GIS/GIL. And the insulation breakdown of epoxy-based spacers is found to be closely related to the electric field distortion under complex operating conditions. In the second topic, original researches on the surface functionally graded materials (SFGM) are presented for relaxing the electric field distortion around the epoxy-based spacers in both AC and DC GIS/GIL, and a series of optimization methods and fabrication techniques for the SFGM spacers are introduced and discussed. In the last topic, the nonlinear conductivity materials (NCM), also known as self-adaptive materials or intelligent materials, are applied as coatings to adaptively regulate the electric field distributions along the surfaces of the epoxy-based spacers. Besides, the concept of the multi-dimensional functionally graded materials (MFGM) is proposed to uniform the electric field distributions in DC GIS/GIL under stationary and transient voltages, exhibiting great potential in the future application.

Available in PDF, EPUB and Kindle. Book excerpt: The increase in demand for electricity and the growing energy density in metropolitan cities have made it necessary to extend the existing high voltage network right up to the consumer. Stepping down the voltage from transmission to the distribution level at the substations located near the actual consumers not only yields economic advantages, but also ensures reliable power supply. Such substations are required to meet a number of severe requirements, including small installation size, effective protection against atmospheric pollution and moisture, noiseless operation, nonexplosive and flame resistant, reduced maintenance, minimal radio interference while providing excellent electric characteristics. Conventional substations using atmospheric air as the main dielectric cannot satisfy these requirements, but totally enclosed substations using sulphur hexafluoride (SF6) gas insulation that are also known as Gas Insulated Substations (GIS). GIS is now in widespread use in the electrical power industry, especially in metropolitan areas. This book will serve as a valuable reference for the novice as well as the expert who needs a wider and detailed scope of coverage within the area of GIS. Gas Insulated Substations provides a comprehensive coverage of a wide range of topics which include: " Introduction to GIS & Properties of SF6 " Layout, Design, Construction, Testing & Maintenance of GIS " Special Problems and Diagnostic Techniques " VFTO Phenomena and its Effects in GIS " Service Experience " Standards Specifications " Future Trends " Extensive References Gas Insulated Substations (GIS) is the first single source for authoritative information on the state of the art in GIS.
