Medium Voltage Drive Systems in Pumping Plants
Medium voltage (2.3kV to 6.6kV) motors are the norm in major Asian pumping plants in Asia to drive their water or waste water pumps. Pumping stations have to control both flow as well as pressure over varying consumer demand. Due to higher demand on productivity and efficiency, the trend for new installations is to design plants with electrical variable speed drives for their motor-pump sets to increase quality, reliability, and productivity over conventional pressure control methods. Energy efficient, modern, medium voltage speed controllers are available for new installations, as well as retrofitting existing fixed-speed motor in older pumping plants.
