Abstract :
In the European Union (EU), Variable Speed Drives (VSDs) was identified as the motor systems technology having the most significant electricity savings potential. In the EU, the identified economic electricity savings potential with the application of VSDs, by 2015, in industrial and tertiary sectors are 39 TWh/year and 8 TWh/year, respectively. However, only a small percentage of this potential is being used. In this paper the characterization of current market of the VSDs is presented, including the average prices, the installation costs, and the total sales in each EU country, per power range. Selected VSD applications are presented. The key barriers to a wider application of VSDs are identified. In particular, the power quality and reliability problems associated with the use of VSDs are presented and possible technical solutions are discussed.
