Reasonable Rated Voltage of High and Medium Power Adjustable-Speed Drives for Energy Saving

Ma Xiaoliang

Strategic Study of CAE 2001, Volume 3, Issue 11, Pages 80-84

Abstract:

A large amount of energy will be saved if adjustable-speed drives are adopted by high and medium powerThe rated voltage of most of the motors in the power range is 10 kV because the power supply is 10 kVbecause this kind of inverter consists of a lot of power electronic devices in series and its cost is highand reliability is poorer than lower voltage one.of the motor and inverter is the same as power supply, i. e. a lower rated voltage can be used for the
