摘要:

London Underground now has some ten years' experience in the use of computer-based systems for the control of its power supply network. The initial application of computer technology, and ideas for future systems, all relate to the evolution of control methods from the early days of manned substations

摘要:

Essential process plant and monitoring systems require battery-backed supplies to ensure continuity of function during mains outages or disturbances. BNFL Engineering has provided many such systems to BNFL's Sellafield Site for both green-field site projects and refurbishment of existing facilities. The factors to be considered in engineering these systems are considered in this article

摘要:

Earlier articles have described how the use of major strategic spare components can improve the availability of large turbogenerators and experience of this strategy in the United Kingdom electricity supply industry. This article outlines the complementary strategies which have been adopted for generator transformers and transmission plant. Applications in respect to transmission transformers, switchgear and circuit and other substation equipment are described. The mutual advantages arising from sharing arrangements and co-operation on the basis of these strategies by the United Kingdom mainland generating boards is noted
