Gearing up for smart MV switchgear

摘要

These are revolutionary times for medium-voltage (MV) distribution systems as they undergo a profound change in role In the past, MV systems were restricted to the distribution of power of consistent quality from a transmission network or conventional generation plant, as well as performing basic switching and protection duties. Now, intermittent local generators, such as wind and solar sources, present a more complex energy flow for the distribution equipment to handle. Furthermore, there are heightened quality and reliability expectations from operators and consumers. This puts the onus on utilities and operators to ensure that their often ageing grids become safer, smarter, more efficient, more reliable, and more environmentally friendly. And in addition they need to be easier to engineer, install and operate. These factors are all driving the development of 'smarter' MV distribution networks.
