Dynamic effects in large scale industrial networks

摘要

Large scale industrial electricity distribution networks are subject to disturbances arising from both static and dynamic causes. These include private generators, heavy motors, and high-speed automation systems. The inclusion of a rigorous network study at the design stage can result in a standardised modular, able to adapt to changes in demand. The protection systems must be rapid and selective, in spite of variations in short-circuit power. Protection against faults in network components can only be provided by a fully redundant system with separate primary and back-up networks.
