This presentation provides a high-level view of the electricity industry and the effects of reform in the industry since privatisation. The impact of this reform from the perspective of the England and Wales transmission system operator (National Grid) is discussed with reference to system design and operation. Issues raised include interconnection with other systems and the future prospects of renewable energy. - Author(s): L. Goehlich ; F. Donazzi ; R. Gaspari

Reliability and economy of energy cables are most important for future power distribution. Several cable plants with new monitoring techniques are already in operation, which promise more flexibility and lower cost. The basic ideas of cable monitoring and principles of now available 'RTTR-temperature monitoring' and 'water penetration monitoring' are introduced. - Author(s): H. Koch and T. Hillers

Environmental requirements make it necessary to build underground transmission systems in special areas with special requirements. Limiting values for the use of overhead lines could be magnetic field restrictions, or just visibility of the overhead line, or limited space. The gas-insulated line (GIL) is one technical solution to allow the transmission of electricity under ground at high transmission ratings. The cost reduction of the second-generation GIL compared to the first generation, and the increased productivity in laying of GIL directly buried or in a tunnel, makes the GIL a high power rating underground transmission solution for the future. - Author(s): I.

Northern Ireland Electricity signed agreements in 1990 with Scottish Power, its counterpart in the south of Scotland, for the construction of an HVDC interconnector, known as the Moyle Interconnector, between the companies' transmission systems. After a protracted period in which all the necessary consents were obtained, contracts have been awarded and, following a construction period of only 27 months, the interconnector started commercial operation at the beginning of 2001. - Author(s): A.M.

An overview of the capacitor commutated converter is given, emphasising its applications in long-cable HVDC transmission schemes. Its advantages and disadvantages in comparison with the conventional HVDC Graetz bridge converter are identified, and a critical assessment of its performance is presented using a developed steady-state formulation as well as a transient simulation based analysis. - Author(s): N.M. Kirby ; Lie Xu ; M. Luckett ; W. Siepmann

Onshore and offshore wind farms are a rapidly growing worldwide industry. The development of larger, more efficient turbines is opening up new frontiers in wind energy generation in the form of large offshore wind farms. The use of high-voltage direct current (HVDC) technology can fully realise the potential of these developments, overcoming the major technical challenges facing traditional AC solutions and providing an efficient, economic and reliable solution. - Author(s): B.R. Andersen ; L. Xu ; P.J. Horton ; P. Cartwright

The increasing rating and improved performance of self-commutated semiconductor devices have made DC power transmission based on voltage-sourced converters possible. This technology is called VSC transmission. The main components in a DC scheme are depicted and their functions explained. The features of three main categories of converter topology suitable for DC transmission are described. Three specific converters, namely two-level, three-level diode-clamped and four-level floating-capacitor converters for a 300 MW scheme, are compared in terms Of costs, DC capacitor volume, commutation inductance and footprint. The floating capacitor converter is shown to yield the lowest system cost. - Author(s): D.J. Hanson ; M.L. Woodhouse ; C. Horwill ; D.R. Monkhouse ; M.M. Osborne

The unbundling of the generation and transmission functions in England and Wales into separate shareholder-owned companies has inevitably resulted in far less predictability in terms of generator siting and closure. National Grid, as the sole transmission company in England and Wales, is required to plan and respond quickly to changing system patterns to maintain both security and power quality standards. This has been achieved by an extensive programme of investment in reactive compensation. To supplement the existing fixed static VAr compensators installed in the last 10-15 years, National Grid has, to date, installed a further 12 relocatable SVCs at sites in England and Wales as part of a planned programme of work to meet these changing system needs. - Author(s): B.

NIE is the electricity transmission and distribution company for Northern Ireland, and the ESB is the electricity generating, transmission and distribution company for the Republic of Ireland. The AC interconnection of both electricity networks brings benefits to each company in the form of sharing the generation reserves, facilitating the liberalising of the electricity market in the island of Ireland and generally improving the quality and continuity of electricity to their respective customers. - Author(s): W.T.
