摘要:

With an increasing number of private generators feeding into the public network, the need to control the quality of supply and safeguard the general public are receiving increasing prominence. Requirements, islanding and CHP schemes are considered in the second of two IEE colloquium reports

摘要:

Of the millions of rotating electrical machines sold each year, the majority are assembled in the ideal conditions of the maker's factory and shipped to the customer in one unit. At the large end of the range, however, when ratings are in tens of megawatts, a size is reached when transport and site handling limitations prevent this. The machine then has to be broken down for shipment into main components such as rotor, stator, baseplate and bearings. For very large machines even this division into components in order to solve the shipping problem, either to modify the design of components, possibly to their detriment, or to assemble them at site where conditions and facilities will not normally be as good as those available at a manufacturer's works. This article describes the special problems that arose at site with two projects, Dinorwig and JET where the option to build at site was chosen, and those that still arose with the QEZ refit when the ideal design of propulsion motor was modified to produce shippable elements.

摘要:

The realisation of the fragility of the Earth's climate has suddenly impinged on the steady long-term planning of the electricity generation industry. Generation planners must cope with not only the environmental problems but also the efforts of politicians and economists to solve them

摘要:

In Part 1 (January 1991) the need for a stable electricity supply was established and the inherent stability of the synchronous generator considered. Part 2 (July 1991) looked at the generator and its controls and introduced the equal-area criterion. Part 3 looks at how to obtain the data necessary for computer modelling when designing new generators.
