They usually reach their nominal speed between 12 and 24 m/s, wind speeds that are rare to be found near the ground in a constant way so they make them high. In order not to be dismembered by the centrifugal force, the big ones have brakes that keep them at a maximum turning speed in case of very strong wind. These brakes sometimes fail to result in terrible accidents. Wind ...
The system now handles in excess of 100,000 digital signals and 20,000 analogue values sourced from more than 100 Rockwell SLC500 and PLC5 based outstations encompassing the monitoring and operation of numerous engineering systems including but not limited to: • 33kV and 11kV high voltage electrical network • Firemain system • ...

Spectral analysis applied to graphs is not a new tool, but analyses of the real world, especially of technological networks, currently are lacking. We show the spectral pattern of a high voltage power network, calculate the ratio between the smallest and largest non–zero Laplacian eigenvalue to check its synchronisability and ...
Concerns over global warming and high oil prices are expected to lead to a continuous increase in electricity generated by distributed renewable energy sources and small-scale embedded generators (SSEGs). ...
The electricity network represents an example of an evolving complex system. The first local networks contained only a few nodes, but within several decades, they have evolved into a highly connected continental system. The growth of these networks was influenced by various factors such as economic, demographic, political and technological ...
